i5 750 OC

post #1 of 4
Thread Starter 
Here are my settings and perhaps some of my own thoughts on this specific setup and CPU.
Asus P7P55D-E P55 Motherboard with. Bios Version 1404 American Megatrends Inc. 10/29/2010, CMX4GX3M2A2000C9 total 4 sticks-8GB 2000 MHz. The cpu cooler is NH-D14 with both fans, inside a HAF 932 stock case.

Please forgive me that the uploaded images are not clear. I do believe however, if you do not use glass eyes you will be able to decipher the symbols on them regardless of their poor image quality.

The only two areas in the bios that I changed directly that aren't shown in the pictures are as follows, AHCI and I keyed in the ram timings which are 9-9-9-24. The rest are here.

idle temp. 39c Happy Near Year!

Only thing I recommend is to try and drop your CPU voltage & IMC voltage. You can enable Load Line Calibration, that way there would not be such a big drop in voltage from bios to windows and from Idle to load....

Both are listed on Intel Data Sheets as 1.40 Absolute Max..

Also another tip, if possible run 200 bclk with a 20x ratio, this way your ram will run at 2000.....

otherwise it looks good. Dont be afraid to leave OCCT medium data running overnight to ensure its stable as well

My Vcore drops to 1.296 during full load, which drops the temps. in a serious fashion.
Idle the Vcore is different.

Yeah, that is what Load Line Calibration is for, it reduce the voltage drop significantly.

You can run stable at 1.296v, so you set the bios voltage to 1.325, enable load line calibration and boot to windows, start occt and see what the load voltage is... If it is higher that 1.296v then you know you can lower it in bios.

This will give you a lower idle voltage and temp...

Also your IMC is too high. Try dropping it down and stress testing... You will burn it up at those volts.. IMC = "Internal Memory Controller" aka QPI & VTT, max safe voltage is 1.40v
