Help me get to 4.0ghz E8400!

post #1 of 37
Thread Starter 
Ok, i decided i want 4.0ghz no matter what. 3.8 just does not sit well with me.

Heat is not really a problem. so far but...I have a few questions.

first, in my bios of my 750i ftw i have 1.381 vots but in cpuz i get 1.344 idle and 1.336 under load. Which of the volts should i be focused on? Is there a definite vdrop in this board?

that is a pretty high vcore for that overclock. did you try 4.0 at that vcore. and yes there is a vdroop on that board. you have to do the mod.

start overclocking

1.336v is what the CPU is getting at load, don't let that go above 1.45. Try going for 4.0Ghz with that voltage, if it doesn't stay stable, up the voltage. Have you increased the NB voltage at all? SB? Ram settings?

1.36 is ok for 4ghz (450x9)

right now my nforce spp is 1.4 and my nf200 is 1.4 * but it says current value is 1.20* for some reason.
Which is my north bridge?

How the hell did you get DDR2 to run at 1.5v? 1.45v is not needed with HIS E8400.
