Upgraded my BIOS and decided to OC my chip. I'm following a guide over at
Overclock.net to do so. Here were the preliminary steps:
To be set before starting overclock
On ASUS P8P67 Pro Motherboard, hopefully the names for voltage settings etc wont be too different across motherboards.
AI Overclock Tuner - Manual
BCLK/PEG frequency - 100 (Never Change this)
Turbo Ratio - By All Cores
EPU Power Saving Mode - Disable
VRM Frequency - Manual and 350
CPU Current Capability - 140%
CPU PLL Overvoltage - Disabled
Load-Line Calibration - Ultra High
Phase Control/Duty Control - Extreme
NOTICE: Please use Manual CPU Vcore whilst stress testing until you have found your stable amount, this helps to keep the voltage stable and rules that out as a possible caus of instability if you are having problems. After testing and when you have found your stable vcore, switch to Offset voltage for reduced power use,
Make sure you set cpu vcore to manual and enter the correct amount of vcore, do NOT use 'Auto' voltage as this can use voltages like its going out of fashion (mine decided 1.504v was a good idea )
Now for the Voltages
CPU Voltage - Set to 1.20v which is stock CPU voltage for now
DRAM Voltage - 1.65/1.50 etc as per your memory module label
VCCSA - Auto
VCCIO - Auto
CPU PLL Voltage - Auto
PCH Voltage - Auto
CPU Spread Spectrum - Enabled
CPU configurations
CPU Ratio - Auto
Intel Adaptive Thermal Monitor - Enabled
Active Processor Cores - All
Limit CPUID Maximum - Disabled
Execute Disable Bit - Enabled
Intel Virtualization Technology - AFAIK This is only necessary for F@H on a 2500k
Enhanced Intel Speedstep Technology - Enabled
Turbo Mode - Enabled
CPU C1E - Enabled/Auto
CPU C3 Report - Auto
CPU C6 Report - Auto
I started at 1.2v @4ghz as they suggested and also ran the Prime95 test with their recommended settings:
Custom, 1344 FFT - 1344FT, Available ram use all your ram but leave 1.5GB (1GB for windows and 500mb spare), and set cycles to 1 minutes. So it should look like this:
If you can pass 15-20 mins of this test, restart the tortue test and use 1792 - 1792 for the FFT size. Agaian do this for 15-20 mins.
If you can do both these tests, you have a good indication of the cpu being stable, and you can either go ahead and do an overnight p95 blend test if you want full stability, or increase the CPU multiplier.
Currently set at 1.26v:
Are these numbers in the pic looking good so far? I need to do the second test that they recommend, but I was just curious as to how it was looking so far (from those with more OC experience).
