Recommended memory configurations  
2-5  
ASUS P8B75-V  
 
Memory configurations  
You may install 1GB, 2GB, 4GB and 8GB unbuffered and non-ECC DDR3 DIMMs into the  
DIMM sockets.  
You may install varying memory sizes in Channel A and Channel B. The system maps  
the total size of the lower-sized channel for the dual-channel configuration. Any excess  
memory from the higher-sized channel is then mapped for single-channel operation.  
According to Intel CPU spec, DIMM voltage below 1.65V is recommended to protect  
the CPU.  
Always install DIMMs with the same CAS latency. For optimum compatibility, we  
recommend that you obtain memory modules from the same vendor.  
Due to the memory address limitation on 32-bit Windows OS, when you install 4GB  
or more memory on the motherboard, the actual usable memory for the OS can be  
about 3GB or less. For effective use of memory, we recommend that you do any of the  
following:  
- Use a maximum of 3GB system memory if you are using a 32-bit Windows OS.  
- Install a 64-bit Windows OS when you want to install 4GB or more on the  
motherboard.  
For more details, refer to the Microsoft® support site at  
http://support.microsoft.com/kb/929605/en-us.  
This motherboard does not support DIMMs made up of 512Mb (64MB) chips or less  
(Memory chip capacity counts in Megabit, 8 Megabit/Mb = 1 Megabyte/MB).  
The maximum 32GB memory capacity can be supported with 8GB or above DIMMs.  
ASUS will update the memory QVL once the DIMMs are available in the market.  
The default memory operation frequency is dependent on its Serial Presence Detect  
(SPD), which is the standard way of accessing information from a memory module.  
Under the default state, some memory modules for overclocking may operate at a  
lower frequency than the vendor-marked value. To operate at the vendor-marked  
or at a higher frequency, refer to section 3.4 Ai Tweaker menu for manual memory  
frequency adjustment.  
For system stability, use a more efficient memory cooling system to support a full  
memory load (4 DIMMs) or overclocking condition.

Jumper  
Clear RTC RAM (3-pin CLRTC)  
This jumper allows you to clear the Real Time Clock (RTC) RAM in CMOS. You can  
clear the CMOS memory of date, time, and system setup parameters by erasing  
the CMOS RTC RAM data. The onboard button cell battery powers the RAM data in  
CMOS, which include system setup information such as system passwords.

Normal  
Clear RTC  
(Default)  
P8B75-V Clear RTC RAM  
To erase the RTC RAM:  
1.  
2.  
Turn OFF the computer and unplug the power cord.  
Move the jumper cap from pins 1-2 (default) to pins 2-3. Keep the cap on pins 2-3  
for about 5-10 seconds, then move the cap back to pins 1-2.  
3.  
4.  
Plug the power cord and turn ON the computer.  
Hold down the <Del> key during the boot process and enter BIOS setup to re-  
enter data.  
Except when clearing the RTC RAM, never remove the cap on CLRTC jumper default  
position. Removing the cap will cause system boot failure!  
If the steps above do not help, remove the onboard battery and move the jumper again  
to clear the CMOS RTC RAM data. After clearing the CMOS, reinstall the battery.  
You do not need to clear the RTC when the system hangs due to overclocking. For  
system failure due to overclocking, use the CPU Parameter Recall (C.P.R.) feature.  
Shut down and reboot the system, then the BIOS automatically resets parameter  
settings to default values.

Onboard switches  
Onboard switches allow you to fine-tune performance when working on a bare or open-  
case system. This is ideal for overclockers and gamers who continually change settings to  
enhance system performance.  
1.  
MemOK! switch  
Installing DIMMs that are incompatible with the motherboard may cause system  
boot failure, and the DRAM_LED near the MemOK! switch lights continuously. Press  
and hold the MemOK! switch until the DRAM_LED starts blinking to begin automatic  
memory compatibility tuning for successful boot.  
P8B75-V  
P8B75-V MemOK! switch  
Refer to section 2.2.7 Onboard LEDs for the exact location of the DRAM_LED.  
The DRAM_LED also lights when the DIMM is not properly installed. Turn off the  
system and reinstall the DIMM before using the MemOK! function.  
The MemOK! switch does not function under Windows OS environment.  
During the tuning process, the system loads and tests failsafe memory settings. It  
takes about 30 seconds for the system to test one set of failsafe settings. If the test  
fails, the system reboots and test the next set of failsafe settings. The blinking speed  
of the DRAM_LED increases, indicating different test processes.  
Due to memory tuning requirement, the system automatically reboots when each  
timing set is tested. If the installed DIMMs still fail to boot after the whole tuning  
process, the DRAM_LED lights continuously. Replace the DIMMs with ones  
recommended in the Memory QVL (Qualified Vendors Lists) in this user manual or on  
the ASUS website at www.asus.com.  
If you turn off the computer and replace DIMMs during the tuning process, the system  
continues memory tuning after turning on the computer. To stop memory tuning, turn  
off the computer and unplug the power cord for about 5–10 seconds.  
If your system fail to boot due to BIOS overclocking, press the MemOK! switch to boot  
and load BIOS default settings. A message will appear during POST reminding you  
that the BIOS has been restored to its default settings.  
We recommend that you download and update to the latest BIOS version from the  
ASUS website at www.asus.com after using the MemOK! function.

BIOS setup  
3.1  
Knowing BIOS  
The ASUS UEFI BIOS offers a user-friendly interface that goes beyond traditional  
keyboard-only BIOS controls to enable more flexible and convenient mouse input. Users  
can easily navigate the UEFI BIOS with the same smoothness as their operating system.  
The term “BIOS” in this user manual refers to “UEFI BIOS” unless otherwise specified.  
BIOS (Basic Input and Output System) stores system hardware settings such as storage  
device configuration, overclocking settings, advanced power management, and boot device  
configuration that are needed for system startup in the motherboard CMOS. In normal  
circumstances, the default BIOS settings apply to most conditions to ensure optimum  
performance. We recommend that you not change the default BIOS settings except in  
the following circumstances:  
An error message appears on the screen during the system bootup and requests you to  
run the BIOS Setup.  
You have installed a new system component that requires further BIOS settings or  
update.  
Inappropriate settings of the BIOS may result to instability or failure to boot. We strongly  
recommend that you change the BIOS settings only with the help of a trained service  
personnel.  
3.2  
BIOS setup program  
A BIOS setup program is provided for BIOS item modification. When you start up the  
computer, the system provides you with the opportunity to run this program. Press <Del>  
during the Power-On Self-Test (POST) to enter the Setup utility. Otherwise, POST continues  
with its test routines.  
If you wish to enter Setup after POST, press <Ctrl> + <Alt> + <Delete>, or press the reset  
button on the system chassis to restart the system. You can also turn the system off and then  
turn it back on to restart the system. Do this last option only if the first two failed.  
The BIOS setup screens shown in this section are for reference purposes only, and  
may not exactly match what you see on your screen.  
Ensure that a USB mouse is connected to your motherboard if you want to use the  
mouse to control the BIOS setup program.  
If the system becomes unstable after changing any BIOS setting, load the default  
settings to ensure system compatibility and stability. Select the Load Optimized  
Defaults item under the Exit menu. See section 3.9 Exit Menu for details.  
If the system fails to boot after changing any BIOS setting, try to clear the CMOS and  
reset the motherboard to the default value. See section 2.2.8 Jumper for information  
on how to erase the RTC RAM.  
The BIOS setup program does not support the bluetooth devices.  
The BIOS setup program is designed to make it as easy to use as possible. Being a  
menu-driven program, it lets you scroll through the various submenus and select from the  
available options using a keyboard or a USB mouse.  
The BIOS setup program can be used under two modes: EZ Mode and Advanced Mode.  
You can change modes from the Exit menu in the Advanced Mode screen or from the  
Advanced Mode button in the EZ Mode screen.

CPU Load-line Calibration  
It allows you to adjust the voltage settings and control the system temperature. Higher load-line  
calibration could get higher voltage and good overclocking performance but increases the CPU  
and VRM thermal.  
1
CPU Current Capability  
CPU Current Capability provides wider total power range for overclocking. A higher value  
setting gets higher VRM power consumption delivery.  
2
3
VRM Fixed Frequency Mode  
Switching frequency will affect the VRM transient response and component thermal. Higher  
frequency gets quicker transient response.  
iGPU Load-line Calibration  
Load-line is defined by Intel VRM specifications, and affects the iGPU voltage. The iGPU  
working voltage will decrease proportionally to integrated graphics loading. A higher value can  
get a higher iGPU voltage, and a good performance, but increases the CPU and VRM thermal  
conditions.  
4
iGPU Current Capability  
A higher value brings a wider total iGPU power range and extends the overclocking frequency  
range simultaneously to enhance the iGPU performance.  
5
6
CPU Power Phase Control  
Increase phase number under heavy system loading to get more transient and better thermal
