clear your cmos first
these are the important things you must know
CPU frequency = bclock x CPU clock ratio
This is a biggest change from the old LGA 775 where FSB and multiplier determined the CPU speed. The base clock is similar to the FSB but also has some key differences. The bclock is the basis for all the other frequencies
QPI frequency = bclock x QPI clock ratio
QPI is the Intel communication path between the CPU and the X58 chipset on the motherboard. So all devices not controlled on the CPU die itself have to communicate with the CPU via the QPI.
Uncore frequency = bclock x uncore clock ratio
Uncore is everything on the die that is not core, primarily, the memory controller and the L3 cache. ->VTT voltage.
Memory frequency = bclock x System Memory Multiplier (SPD)
Memory is shown in the BIOS as a multiplier of 6, 8, 10, etc
CPU Vcore Directly related to the CPU frequency
QPI/VTT voltage This is the uncore voltage.
DRAM voltage This is directly related to your RAM modules and increases will allow increase in MEM speeds
default VTT is 1.15V and the DRAM voltage has to stay within 0.5V of the VTT
now all you do is Maximize Bclock & uncore Frequency. start by entering the BIOS and select load optimized defaults, then save and exit. After the reboot, go back into the BIOS and turn off the start-up slash screen, so that you can view your systems post behavior. Also, feel free to disable any integrated peripherals that will not be used (i.e. NICs, extra PATA/SATA controllers, legacy devices, etc). All other overclocking settings you can leave on auto. disable all power saving features. These include, but are not limited to; EIST, C1E, and all other C-states.
you need to isolate the bclock, because all other major devices derive their frequencies from the bclock. In order to isolate the bclock, the first thing you need to do is manually force a low multiplier for the CPU.
isolate the bclock from the memory by dropping the multiplier normally 8 to its lowest
Lock in your desired uncore clock ratio. the the uncore clock ratio must be set to double the System Memory Multiplier (SPD). remeber set the uncore clock ratio based on your desired System Memory Multiplier (SPD) (not the temporary memory multiplier your using right now.
then IOH Core voltage-----> if you are running a single PCIe card (gpu), give the IOH Core 1.1V
QPI/VTT voltage--------> 1.2V
safe it reboot back into bios
bclock-------> from 133MHz to 150MHz.
save and exit and allow the system to reboot into windows
start up RealTemp. start up CPU-Z. run 3 loops with IntelBurnTest
If the test ran without error, raise the bclock by 10MHz, reboot into your OS and run the test again.
If the test failed, raise the QPI/VTT voltage by 0.025V, reboot into your OS and run the test again.
Continue to repeat this till you reach the same bclock speed you wanted or reach your maximum safe QPI/VTT voltage (1.3v) or Raising the QPI/VTT voltage is ineffective in stabilizing the system
