Max VCore for e6400

post #1 of 12
Thread Starter 
So...what is the max vcore for a e6400 in general?

What is the max?

What is the most i should go to without taking life off the cpu?

Anyone have an examples of what speed they can hit with each vcore?

Any help will be appreciated

Does it get into Windows and then freeze? Does it freeze during the boot sequence? You can try moving up the vCore one notch to see if that has any effect. More than likely you'll have to put your ram on a lower divider (1:1 with your FSB) until you find the max stable clock of your cpu.

There are more voltages than just vcore in overclock. There's RAM voltage and MCH voltage. MCH is the FSB that you raise to get your CPU at higher clock speeds. You may need to raise that to stabilize.

I can't reach 313FSB with default MCH. With +0.1FSB, I can reach 535 before I hit a wall.

So you see the bios screen, which most likely means you've also heard the beep when the computer POSTs. Go into your bios and loosen up your ram timings a little bit. Try 5-5-5-15 @ 2.0-2.1V on the RAM. See if this will post.
