UEFI settings for ASUS Z77 motherboards are considered using the example of ASUS PZ77-V LE board with Ivy Bridge i7 processor. The optimal parameters were chosen for some complex UEFI settings that allow you to get successful overclocking without undue risk. The user consistently gets acquainted with the basic concepts of overclocking and performs reliable and not extreme overclocking of the processor and memory of ASUS Z77 motherboards. For simplicity, UEFI English is used.
The post is coolly received on the site of overclockers. This is understandable, since this site is mostly reckless reckless users involved in extreme overclocking.

AI Overclock Tuner

All actions related to overclocking are carried out in the AI ​​Tweaker (UEFI Advanced Mode) menu by setting the AI ​​Overclock Tuner parameter to Manual (Fig. 1).

BCLK/PEG Frequency

The BCLK/PEG Frequency parameter (hereinafter referred to as BCLK) in fig. 1 becomes available when Ai Overclock TunerXMP or Ai Overclock TunerManual is selected. The BCLK frequency of 100 MHz is the base frequency. The main overclocking parameter is the frequency of the processor core, obtained by multiplying this frequency by the parameter - the processor multiplier. The end frequency is displayed in the upper left of the Ai Tweaker window (it is 4.1 GHz in Figure 1). The BCLK frequency also regulates memory frequency, bus speeds, and so on.
The possible increase in this parameter during overclocking is small - most processors allow you to increase this frequency only up to 105 MHz. Although there are separate samples of processors and motherboards for which this value is 107 MHz or more. With careful overclocking, taking into account the fact that in the future the computer will be installed additional devices, this parameter is recommended to be left equal to 100 MHz (Fig. 1).

ASUS MultiCore Enhancement

When this setting is enabled (Enabled in Figure 1), the ASUS policy for Turbo mode is accepted. If the setting is disabled, the Intel policy for Turbo mode will be applied. For all overclocking configurations, it is recommended to enable this option (Enabled). The disable option can be used if you want to run the processor using Intel policy without overclocking.

Turbo Ratio

In the window of Fig. 1 set this parameter to Manual mode. Going to the Advanced...CPU Power Management Configuration menu (Fig. 2) set the multiplier to 41.

Rice. 2
We return to the AI ​​Tweaker menu and check the value of the multiplier (Fig. 1).
For very careful users, we can recommend the initial value of the multiplier equal to 40 or even 39. The maximum value of the multiplier for non-extreme overclocking usually less than 45.

Internal PLL Overvoltage

Increasing (overclocking) the operating voltage for the internal phase-locked loop (PLL) allows you to increase the operating frequency of the processor core. Selecting Auto will automatically enable this setting only when the processor core multiplier increases beyond a certain threshold.
For good samples of processors, this parameter should be left on Auto (Fig. 1) when overclocked to a multiplier of 45 (to a processor frequency of 4.5 GHz).
Note that the stability of waking up from sleep may be affected when this parameter is set to Enabled. If you find that your processor will not overclock to 4.5 GHz without setting this parameter to Enabled, but the system is unable to wake up from sleep, then running at a lower frequency with a multiplier of less than 45 is the only choice. overclocking with multipliers equal to or greater than 45, it is recommended to set Enabled. With careful acceleration, select Auto. (Fig. 1).

CPU bus speed: DRAM speed ratio mode

This setting can be left in the Auto state (Figure 1) to apply changes later when overclocking and adjusting the memory frequency.

memory frequency

This setting is shown in Fig. 3. It is used to select the frequency of the memory.

Rice. 3
The Memory Frequency setting is determined by the BCLK frequency and the CPU bus speed:DRAM speed ratio mode setting. The memory frequency is displayed and selected from the drop-down list. The set value can be checked in the upper left corner of the Ai Tweaker menu. For example, in fig. 1 we see that the memory frequency is 1600 MHz.
Note that Ivy Bridge processors have a wider range of memory frequency settings than the previous generation of Sandy Bridge processors. When overclocking the memory, together with an increase in the BCLK frequency, it is possible to carry out a more detailed control of the memory bus frequency and obtain the maximum possible (but possibly unreliable) results with extreme overclocking.
For reliable use of overclocking, it is recommended to increase the frequency of memory sets by no more than 1 step relative to the passport one. Higher memory speeds provide little performance gain in most programs. In addition, system stability at higher memory operating frequencies often cannot be guaranteed for individual CPU-intensive programs, or when going to sleep and back.
It is also recommended to opt for memory kits that are on the list of recommended ones for the selected processor if you do not want to spend time on setup stable operation systems.
Operating frequencies between 2400 MHz and 2600 MHz seem to be optimal in combination with intensive cooling of both processors and memory modules. Higher speeds are also possible by reducing secondary parameters - memory timings.
With careful overclocking, we start by overclocking only the processor. Therefore, at first it is recommended to set the passport value of the memory frequency, for example, for a set of DDR3-1600 MHz memory sticks, we set 1600 MHz (Fig. 3).
After overclocking the processor, you can try to increase the memory frequency by 1 step. If errors appear in stress tests, then you can increase the timings, supply voltage (for example, by 0.05 V), VCCSA by 0.05 V, but it is better to return to the nominal frequency.

EPU Power Saving Mode

The automatic EPU system was developed by ASUS. It regulates the frequency and voltage of the computer elements in order to save energy. This setting can only be enabled at the processor's rated operating frequency. For overclocking, turn off this parameter (Disabled) (Fig. 3).

OC Tuner

When (OK) is selected, a series of stress tests will run during the Boot process in order to automatically overclock the system. Final overclock will vary based on system temperature and memory kit used. It is not recommended to enable it, even if you do not want to manually overclock the system. We do not touch this item or select cancel (Fig. 3).

DRAM Timing Control

DRAM Timing Control is the setting of memory timings (Fig. 4).

Rice. four.
All these settings must be left equal to the passport values ​​and on Auto if you want to set up the system for reliable operation. The main timings must be set according to the SPD of the memory modules.

Rice. 5
Most of the parameters in Fig. 5 is also left in Auto.

MRC Fast Boot

Enable this option (Enabled). This skips the memory test during the system reboot procedure. This reduces the loading time.
Note that when using a larger number of memory sticks and at a high frequency of modules (2133 MHz and higher), disabling this setting can increase system stability during overclocking. As soon as we get the desired stability during overclocking, turn on this parameter (Fig. 5).

DRAM CLK Period

Specifies the latency of the memory controller in conjunction with the applied memory frequency. A setting of 5 gives the best overall performance, although stability may be degraded. Set it better to Auto (Fig. 5).

CPU Power Management

The window of this menu item is shown in fig. 6. Here we check the processor multiplier (41 in Fig. 6), be sure to enable (Enabled) the EIST power saving parameter, and also set the threshold processor powers if necessary (all the last mentioned parameters are set to Auto (Fig. 6)).
Going to the Advanced...CPU Power Management Configuration menu item (Fig. 2), set the CPU C1E (power saving) parameter to Enabled, and the rest (including parameters with C3, C6) to Auto.

Rice. 7.

DIGI+ Power Control

CPU Load-Line Calibration

The abbreviation for this parameter is LLC. With a fast transition of the processor to an intensive mode of operation with increased power consumption, the voltage on it abruptly decreases relative to the stationary state. Increased LLC values ​​cause an increase in the processor supply voltage and reduce processor supply voltage drops during an abrupt increase in power consumption. Setting the parameter to high (50%) is considered optimal for 24/7 mode, providing an optimal balance between voltage rise and supply voltage drop. Some users prefer to use higher LLC values, although this will affect the drawdown to a lesser extent. Set high (Fig. 7).

VRM Spread Spectrum

Enabling this setting (Figure 7) enables extended modulation of the VRM signals to reduce the peak in the spectrum of radiated noise and interference in nearby circuits. Enabling this parameter should only be used at nameplate frequencies, since signal modulation can degrade the transient response of the power supply and cause instability in the supply voltage. Install Disabled (Fig. 7).

current capacity

A value of 100% on all these parameters should be enough to overclock processors using conventional cooling methods (Figure 7).

Rice. eight.

CPU Voltage

There are two ways to control processor core voltages: Offset Mode (Figure 8) and Manual. Manual mode provides an always constant static voltage level on the processor. This mode can be used for a short time, when testing the processor. Offset Mode allows the processor to adjust the voltage depending on the load and operating frequency. Offset Mode is preferred for 24/7 systems, as it allows the processor to reduce the supply voltage when the computer is idle, reducing power consumption and core heating.
The supply voltage level will increase as the multiplier (multiplier) for the processor increases. So it's best to start with a low multiplier of 41x (or 39x) and go up one step, checking for stability each time you go up.
Set Offset Mode Sign to “+” and CPU Offset Voltage to Auto. Load the processor with calculations using the LinX program and check the processor voltage with CPU-Z. If the voltage level is very high, then you can reduce the voltage by applying a negative offset in UEFI. For example, if our total supply voltage at a multiplier of 41x turned out to be 1.35V, then we could reduce it to 1.30V by applying a negative bias of 0.05V.
Keep in mind that a reduction of approximately 0.05V will also be used for the open circuit voltage (with light load). For example, if with default settings the processor idle voltage (at a multiplier of 16x) is 1.05V, then subtracting 0.05V will give approximately 1.0V of the idle voltage. Therefore, if you reduce the voltage using too high CPU Offset Voltage values, there will come a point when the idle voltage is so low that it will cause the computer to malfunction.
If for reliability it is necessary to add voltage at full load of the processor, then we use the “+” offset and increase the voltage level. Note that both "+" and "-" offsets are not accurately handled by the processor's power system. Correspondence scales are non-linear. This is one of the features of VID, which is that it allows the processor to ask for different voltages depending on the operating frequency, current and temperature. For example, with a positive CPU Offset Voltage of 0.05, a voltage of 1.35 V under load can only increase to 1.375 V.
From the foregoing, it follows that for non-extreme overclocking for multipliers approximately equal to 41, it is best to set Offset Mode Sign to “+” and leave the CPU Offset Voltage parameter to Auto. For Ivy Bridge processors, most samples are expected to run at 4.1 GHz with air cooling.
More overclocking is possible, although when the processor is fully loaded, this will cause the processor temperature to rise. To control the temperature, run the RealTemp program.

DRAM Voltage

We set the voltage on the memory modules in accordance with the passport data. This is usually about 1.5 V. The default is Auto (Figure 8).

VCCSA Voltage

This parameter sets the voltage for the System Agent. You can leave it on Auto for our overclocking (Fig. 8).

CPU PLL Voltage

For our overclocking - Auto (Fig. 8). The usual values ​​​​of the parameter are about 1.8 V. By increasing this voltage, you can increase the processor multiplier and increase the memory frequency above 2200 MHz, because. a slight overvoltage over the nominal voltage can help the stability of the system.

PCH Voltage

You can leave the default values ​​(Auto) for a small overclock (Fig. 8). To date, no significant relationship has been found between this chip voltage and other motherboard voltages.

Rice. 9

CPU Spread Spectrum

When the option is enabled (Enabled), the processor core frequency is modulated to reduce the peak value in the emitted noise spectrum. It is recommended to set the parameter to Disabled (Fig. 9), because during overclocking, frequency modulation can degrade system stability.

RAM
When using two memory modules, install them in the red slots (located closer to the processor).

iGPU (integrated graphics core)
The integrated graphics core generates heat during operation. It is logical that by disabling it, you can achieve better overclocking results. Use a PCI-Express video card and in the BIOS disable (Disabled) the function iGPU Multi-Monitor Support to disable the graphics core.

CPU Cooling
Use only the most best systems cooling, because LGA1150 processors are somewhat hotter than they could be, and under heavy loads, protection (Thermal Throttling) may be triggered. When overclocking, it is strongly recommended to use such cooling systems that would blow the radiators on the power subsystem. Or provide them with other fans blowing.
Haswell processors are very sensitive to temperature. The better you cool them, the more you can overclock. It has been experimentally proven that at negative temperatures the overclocking results are impressive even at reasonable voltage values. If you plan to assemble a system, for example, with a freon cooling system, then be sure to take care of isolating electronic components from condensate. You can view the processor temperature in the CoreTemp utility.
Now you can proceed to the recommendations for setting up the system in the BIOS.

UEFI BIOS

The Maximus VI Extreme comes preloaded with 5 overclocking profiles. They can become the basis for overclocking your instance of the processor - it will only be necessary to slightly adjust the parameters.

Set parameter AI Overclock Tuner into meaning Manual to access the BCLK control. You can set X.M.P mode. to set all basic parameters random access memory in accordance with the characteristics declared by the manufacturer. This mode can also be selected as the basic mode, then its settings can be adjusted.

CPU Strap sets different values ​​of straps for the processor. This will allow you to overclock BCLK to the maximum possible values ​​​​for your processor.
The relationship between the BCLK, PCIE and DMI frequencies is as follows: PEG Frequency = DMI Controller Frequency = 100 x (BCLK / CPU Strap).
Remember that for different processors, workable straps may differ.

Source option clock tuner will be unavailable if the value CPU Strap not set to a fixed value.

Parameter PLL Selection can be set to Self Biased Mode (SB-PLL), which will result in better BCLK (base frequency) overclocking, but may degrade PCI-E 3.0 performance due to increased PCI-E digital signal jitter (jitter). User can set Inductance/Capacitance Mode (SB-LC) to minimize PCI-E jitter for better compatibility with PCI-E 3.0 devices.

Parameter FilterPLL can be set to High BCLK Mode to achieve high BCLK values, but this threatens to increase jitter. This mode of operation is usually required to set BCLK above 170 MHz. If you do not need such values, then feel free to set the mode Low BCLK Mode.

ASUS MultiCore Enhancement must be turned on Enabled) so that the system will automatically raise the processor frequency to the maximum value according to your settings when they exceed the standard values.
Internal PLL Overvoltage must be turned on Enabled) for the greatest overclocking by the multiplier. But also remember that the operation of S3 / S4 may lead to the inability of some RAM modules to work.
Parameter CPU bus speed: DRAM speed ratio can be set to 100:100 or 100:133. Selecting one of these ratios can be helpful in setting the exact frequency of your RAM. With a DMI/PEG frequency ratio of 1:1, increasing the DMI/PEG frequency by 1% will also increase the memory frequency by 1%.

Inclusion Extreme Tweaking can achieve performance gains in older benchmarks.

Fully Manual Mode- An exclusive mode from ASUS, thanks to which you can manually adjust six key voltages per processor. In this mode, the processor will not reduce any of the six voltages during idle, even if EIST or C-States are enabled. If you need power saving, then you need to turn off this option.

The three most important stresses CPU Core Voltage, CPU Graphics Voltage, CPU Cache Voltage can be set to manual tuning mode ( Manual) to make the options available CPU Core Voltage Override, C PU Graphics Voltage Override and CPU Cache Voltage Override. In this mode of operation, the internal voltage regulator supplies accurate voltage to the CPU Vcore, CPU Graphics, and CPU Cache. This mode will start working as soon as the Voltage Override values ​​exceed the Auto values. In this mode, idle voltages will not decrease even if EIST or C-States are enabled.

Parameter offset mode opens mode Offset Mode Sign to change voltages CPU Core Voltage Offset, CPU Graphics Voltage Offset and CPU Cache Voltage Offset. To set the voltage offset level, change these parameters. Auto mode is a setting by professional ASUS engineers. If you change the voltage to a minimum step of +-0.001 V, then you will get the default voltage.

In mode adaptive mode mode will be available offset mode and additional mode Additional Turbo Mode Voltage for CPU Vcore, CPU Graphics and CPU Cache. Adaptive mode can be thought of as an extension of offset mode. The additional voltage setting will be active during Turbo Boost operation. Auto mode is a setting by professional ASUS engineers. If you change the voltage to a minimum step of +-0.001 V, then you will get the default voltage.

Disabling the function SVID Support stops the processor from interacting with the external voltage regulator. When overclocking, the recommended value is Disabled.
Separation of voltages Initial CPU Input Voltage and Event CPU Input Voltage This will allow you to more accurately set the voltages before and after POST. This allows "unsuccessful" processors to POST with a higher voltage and lower it for further work.

CPU Spread Spectrum must be turned off Disabled) when overclocking the processor.

BCLK Recovery must be turned on Enabled) when overclocking the processor so that the system can boot into the BIOS in safe mode with incorrectly set frequency settings.

CPU Load-Line Calibration can be set to the maximum level (8) so that the voltage does not sag when the processor is loaded during overclocking. The level can be lowered to reduce power consumption and heat generation if the system remains stable.

Parameter CPU Voltage Frequency can be set to "Manual" to select a fixed frequency. The higher the frequency, the more stable the input voltage (CPU Input Voltage). Increasing this frequency may give an increase in BCLK overclocking, but it depends on the processor instance (some may require a lower frequency for about larger BCLK values). It is highly recommended to enable Enable VRM Spread Spectrum or Enable Active Frequency Mode, if you do not intend to set a fixed value for the processor frequency.

VCCIN MOS Volt Control can be increased to improve stability, but heating will also increase. If you set the value Active VGD, VCCIN MOS Volt Control will dynamically adjust based on CPU load.

CPU Power Phase Control must be set to Extreme so that all phases are active. Otherwise, some phases are inactive during downtime. This may allow for increased frequency overclocking.

CPU Power Duty Control must be set to Extreme. In this mode, the preference is given to applying voltage to the iVR, rather than balancing with temperature. In this mode, you can get a little more acceleration.

CPU Current Capability install 140% to move the overcurrent protection threshold. This will increase acceleration.

Meaning CPU Power Thermal Control can be increased if you have problems with power overheating. But it is highly recommended not to change this setting. If you have problems due to overheating, then it is better to put additional cooling on the radiator of the power subsystem.

CPU Input Boot Voltage- the initial voltage from the power subsystem (Extreme Engine DIGI + III) to the integrated voltage controller (FIVR - Fully Integrated Voltage Regulator), which is used before the BIOS is loaded. This voltage is active before the Initial CPU Input Voltage set from Extreme Tweaker is applied. Careful selection of this voltage can help in achieving the maximum frequency of the processor.

CPU Current Capability in meaning 130% shifts the overcurrent protection threshold for DRAM VRM. Helps increase memory overclocking.

DRAM Voltage Frequency in Manual allows you to manually adjust the VRM frequency. The higher the frequency, the more stable the vDDR voltage, which will allow you to achieve greater memory overclocking (do not forget that overclocking is different for each bar).

DRAM Power Phase Control in meaning Extreme does not allow the power phases of the memory to be switched off. This may allow you to increase memory overclocking or increase stability if memory modules are installed in all slots.

Long Duration Packet Power Limit defines the maximum value for triggering throttling when power consumption exceeds a certain level. We can say that this is the first level of protection for the processor from damage. By default, this is the TDP value from Intel. If left in "Auto" mode, it will be set to the value recommended by ASUS (OC Expert Team).

Package Power Time Window- a value in seconds that indicates how much the processor is allowed to work in excess of TDP (the value that we set in the Long Duration Package Power Limit). The maximum possible value is 127.

Short Duration Package Power Limit indicates the maximum possible power consumption at very short-term loads to avoid system instability. This can be considered the second level of protection for the processor. Intel considers 1.25 of the Long Duration Package Power Limit to be normal. While Intel's specification for Short Duration Package Power Limit can be no more than 10ms, ASUS motherboards can withstand much longer.

CPU Integrated VR Current Limit determines the maximum current from the CPU Integrated Voltage Regulator under extremely high loads. The maximum value of 1023.875 essentially disables iVR limit removal, which disables throttling due to exceeding standard parameters current during acceleration.

Frequency Tuning Mode determines the speed of the processor with iVR. Meaning +6% will provide a more stable supply of all six main voltages. Lowering this setting can lower the temperature by several degrees.

Thermal Feedback determines whether the processor will throttling when the external power subsystem overheats. This setting determines whether the overheating protection of the power subsystem will work. If you disable this protection, it is highly recommended to control the heatsink temperature.

CPU Integrated VR Fault Management it is recommended to turn it off if you increase the voltage manually. Disabling can be useful when overclocking.

CPU Integrated VR Efficiency Management recommended to set to high performance to increase overclocking potential. Balanced mode will bring some energy savings.

Power Decay Mode responsible for power saving in idle. When overclocking, it is recommended to turn off ( Disabled).

Idle Power-in Response Regular. Fast mode is set to reduce power consumption.

Idle Power-out Response during overclocking, it is recommended to set to Fast, which allows you to apply a slightly higher voltage to the processor with the shortest delays.

Parameter Power Current Slope with the value LEVEL-4 shifts the throttling time a little further.

Power Current Offset defines the offset of the Power Current Slope parameter. Meaning -100% shifts the CPU throttling time.

Power Fast Ramp Response determines how fast the iVR should respond to a CPU voltage request. The higher the value, the faster the response will be. You can set the value to 1.5 to improve overclocking.

Power Saving Level 1 Threshold defines the minimum power level when the processor should start throttling. Install 0 to disable this feature.

Power Saving Level 2 Threshold- same as above.

Power Saving Level 3 Threshold- same as above.

VCCIN Shadow Voltage- the voltage that is supplied from the external power subsystem to the internal power controller during POST. This voltage is active between CPU Input Voltage and Eventual CPU Input voltage. In Auto mode, the voltage will be set automatically, not above or below safe thresholds.

PLL Termination Voltage (Initial / Reset / Eventual) it is recommended to change during extreme acceleration at low temperatures. The nominal value is 1.2 V. Safe voltages are up to 1.25 V and above 1.6 V. Do not set the voltage between 1.25 V and the iVR voltage to avoid rapid processor degradation.
When overclocking the BCLK over 160 MHz, remember to set the PLL Termination Reset Voltage and Eventual PLL Termination Voltage to the same level as the Eventual CPU Input Voltage or higher. For example, if Eventual CPU Input Voltage is 1.9V, then PLL Termination Reset Voltage and Eventual PLL Termination Voltage must be 1.9V or higher for optimal effect.
If you do not plan to overclock the BCLK over 160 MHz, then the PLL Termination Voltage should be reduced to 1.1 or 1.0 V. Simply put, set this value to 1.25 V or equal to the CPU Input Voltage for optimal results.

X-Talk Cancellation Voltage can be increased if the system is unstable (for example, BSOD 0124). But the effect will be opposite if Max. Vcore Voltage works under LN2 mode - in this case, reducing the voltage will increase stability. The default is 1.00 V.

Cancellation Drive Strength controls the X-Talk Cancellation Voltage mode of operation.

PCH ICC Voltage- voltage to the integrated clock generator. The default is 1.2 V.
For high DMI frequency (>=115MHz) - try 1.2500V or lower.
For low frequency DMI (ICC Ringback Canceller can be configured as follows:
-turn on ( enable) at high DMI frequencies
-switch off ( Disable) at low DMI frequencies

Clock Crossing VBoot- the nominal value is 1.15000 V. Usually, it is necessary to reduce this voltage to increase overclocking. Lower values ​​may help achieve higher DMI frequencies, but may also reduce PCIe 3.0 stability (raise the value if you encounter PCIe 3.0 instability). From experience, 0.8000 V can become the optimal value. Also, increasing this value to 1.65 V can shift the Cold Boot Bug during extreme overclocking (negative temperatures).

Clock Crossing Reset Voltage

Clock Crossing Voltage it is recommended to reduce to increase overclocking. The default value is 1.15000 V. Lowering this value may help increase the DMI frequency, but at the expense of PCIe 3.0 stability. From experience, 0.8000 V can be the optimal value.

DMI De-emphasis Control can be changed manually for better DMI overclocking. But the meaning +6 is optimal.

Parameter SATA Drive Strength can be manually configured to improve SATA stability. The default is 0. You can try to change in both directions.

CPU PCIE Controller in mode Disabled disables the controller built into the PCIEx16 processor to increase performance in 2D benchmarks. In this case, only the PCIE_x4_1 slot remains operational.

GEN3 Preset in Auto mode is the optimal value. But you can try all three preset profiles and choose the most productive one. This is especially useful when testing SLI or CrossFireX configurations.

PLX 0.9V Core Voltage / PLX 1.8V AUX Voltage- voltage control on PLX PEX8747 (PCIE 3.0 bridge).

PCIE Clock Amplitude you can manually adjust to find the best mode at high PCIe frequency (due to high BCLK frequency). More often than not, higher is better.

Internal Graphics(built-in graphics core) it is desirable to disable to improve overclocking.

If you were looking for BIOS settings in pictures, then you have come to the right place.

The changes made will be protected by a lithium battery built into the motherboard and maintaining the required parameters in the event of a voltage loss.

Thanks to the program, it is possible to establish sustainable interaction operating system(OS) with PC devices.

Attention! The present Boot network configuration section allows you to adjust parameters regarding system boot speed, keyboard and mouse settings.

After completing the work or familiarizing yourself with the Bios Setup Utility menu, you must press the burning Exit key, which automatically saves the changes made.

Section Main - Main menu

Let's start with the MAIN section, which is used to modify the settings and adjust the timing.

Here you can independently set the time and date of the computer, as well as configure the connected hard drives and other drives.

To reformat the mode of operation hard drive, you need to choose HDD(for example: "SATA 1" as shown in the picture).

• type- this item indicates the type of connected hard disk;
• LBA Large Mode- Responsible for supporting drives larger than 504 MB. So the recommended value here is AUTO.
• Block (Multi-Sector Transfer) - For more fast work here we recommend choosing the AUTO mode;
• PIO Mode- Enables the hard drive to operate in legacy data exchange mode. It would also be best to select AUTO here;
• DMA Mode- gives direct access to memory. To get a faster read or write speed, select AUTO;
• smart monitoring- this technology, based on the analysis of the operation of the drive, is able to warn of a possible drive failure in the near future;
• 32 bit data transfer This option determines whether the 32-bit communication mode will be used by the standard IDE/SATA chipset controller.

Everywhere, using the "ENTER" key and the arrows, the Auto mode is set. The exception is subsection 32 Bit Transfer, which needs to fix the Enabled setting.

Important! It is required to refrain from changing the "Storage Configuration" option, which is located in the "System information" section and not to allow correction "SATADetectTimeout".

Section Advanced - Additional settings

Now let's start setting up the basic PC nodes in section ADVANCED consisting of several sub-items.

Initially, you will need to set the necessary processor and memory parameters in the Jumper Free Configuration system configuration menu.

By selecting Jumper Free Configuration, you will go to the Configure System Frequency / Voltage subsection, here you can perform the following operations:

• automatic or manual overclocking of the hard drive - AI Overclocking;
• change of clock frequency of memory modules - ;
• Memory Voltage;
• manual mode for setting the chipset voltage - NB Voltage
• changing port addresses (COM, LPT) - Serial and Parallel Port;
• setting controller settings - onboard devices configuration.

Power section - PC power

The POWER item is responsible for powering the PC and contains several subsections that need the following settings:

• Suspend Mode- set the automatic mode;
• ACPI APIC- set Enabled;
• ACPI 2.0- fix the Disabled mode.

BOOT section - boot management

Here it is allowed to define a priority drive, choosing between a flash card, a disk drive or a hard drive.

If there are several hard drives, then the priority hard drive is selected in the Hard Disk sub-item.

The boot configuration of the PC is set in the Boot Setting subsection, which contains a menu consisting of several items:

Hard drive selection

The boot configuration of the PC is set in the Boot Setting subsection,

• Quick Boot– acceleration of loading of OS;
• Logo Full Screen– disabling the screen saver and activating an information window containing information about the download process;
• Add On ROM- setting the order on the information screen of the modules connected to motherboard(MT) through slots;
• Wait For 'F1' If Error- activation of the function of forced pressing "F1" at the moment the system identifies an error.

The main task of the Boot partition is to determine the boot devices and set the required priorities.

• ASUS EZ Flash- using this option, you have the ability to update the BIOS from such drives as: floppy disk, Flash disk or CD.
• AI NET– using this option, you can get information about the connected to network controller cabile.

Section Exit - Exit and save

Particular attention should be paid to the EXIT item, which has 4 operating modes:

• Save Changes- save the changes;
• Discard Changes + EXIT- leave the factory settings in effect;
• Setup Defaults- enter the default parameters;
• Discard Changes- we cancel all our actions.

Given step by step instructions explain in detail the purpose of the main sections of the BIOS and the rules for making changes to improve PC performance.

Bios setting

Bios settings - Detailed instructions in pictures

Save energy - this idea permeates the designs of all modern electronic devices.
Save at any cost, because screams on this topic are extremely popular in modern society. So what do we pay for a rather insignificant, penny savings in energy (a few hours of air conditioning or a heater eat up that savings in a month)?

First off, here's a great article Some Aspects of Power Saving Intel Core i* and Windows for you, which analyzes in detail how modern "power saving" technologies slow down your new powerful computer.
In some cases, the difference is several times, but some tens of watts are saved.
You bought a powerful computer with a doiga-nuclear processor, and at times it slows down strangely, unpredictably, and the sound path is also disrupted (more on that below).
It also gives advice on what to do.
For the full operation of the processor, two conditions must be met:
Disable "C1E" in the BIOS, leaving "C3-C7" states enabled; Never set the power plan to "Energy Saver."

And besides the drop in performance, there is also audible noise. Yes, yes, you heard right.
Modern motherboards have very smart, advanced multi-phase power management schemes, but constant current surges along all power rails generate not only significant electromagnetic interference, but also quite audible (in a quiet room, provided quiet system cooling) whistles-squeaks.

That is why I have turned off C1E - C3 - C6 / 7 processor operating modes for many years, because in the mode with constant processor frequency jumps and cores falling asleep and waking up, the whistle of the power circuit is clearly audible (this is on the Asus motherboard, which is considered good).
Well, because of the micro-brakes too.

But not only the processor power in modern computers has been "greened" to a state of semi-suffocation.
"energy-saving" operating modes for usb are fraught with a keyboard and mouse failure (did you forget that they are all usb now?), "energy-saving" operating modes pci / pci express- constant clicks of interference in the audio path (the sound is something on pci).

Of course, in the OS, all "energy-saving" settings are turned off, the "maximum performance" plan, in which we carefully go through all the points.
This applies to both desktop computers and laptops, which are mainly used
stationary (I remember that setting the power modes of the Asus laptop improved its operation. When working in the "default" modes, the nimble machine seemed to think at times, the mouse and external keyboard fell off regularly).
With frequently worn laptops it is more difficult, you will have to set up 2 work plans.
Wherever you want to increase battery life, you have to include at least some of the "energy-saving" technologies.

The resulting win is definitely worth it, if, of course, you are interested in your new powerful computer, with a powerful wow-core processor, to work quickly and without brakes.

And now about where and how to save.
No need to buy heavy duty power supplies if you will not use this kilowatt.
Any modern PC-shny power supply for 10-20% of the load works worse than 50%.
For most systems, even gaming ones with 1 powerful video card, where the video card eats up the main thing, a 500-watt PSU is more than enough, and if the machine is not a gaming machine, then 300-350 W is enough.

Install a high-efficiency power supply if you don't mind the money (the aspects of their work with a UPS, because they are almost all with apfc, are a separate issue).
Ceteris paribus, choose more economical processors - in the case of x86 / 64, modern core * from Intel consume about half as much as analogues from AMD, in all modes except idle (at any load different from zero). Moreover, they work noticeably faster in most real tasks.
No need to buy powerful gaming graphics cards, if you do not play 3d games at all - even in normal 2D or video viewing mode, a top-end gaming card eats several times more than a built-in processor or entry-level discrete.
