Most vcore you can put on an Intel Wolfdale 7400.

post #1 of 6
Thread Starter 
I'm on a quest to get that chip up to 4 gigahertz. Got it to 3.7 stable so far. I think I set the vcore at 1.6

DROP THAT VCORE NOW! Anything past 1.365V will degrade the chip. 1.45V is the absolute max.

If I remember correctly that's a 45nm chip. I think somewhere around 1.4V is the 24/7 limit before you see any serious degradation. If this is a suicide run however, there is no limit!

If you can't get 4Ghz with around 1.6V on a 45nm chip, it ain't gonna happen. Your best bet is to get a better motherboard which more voltage options (PLL, VTT, etc) and a higher quality design. At that point though, you may as well get a new CPU as well.

I got it at 1.3 running 3.4. Good enough for my son.

Too much. 1.45 is the absolute limit on those and that's "outside operational range" according to Intel.

I ran my old one at 1.456 for 2+ years @ 4 GHz--no burnt pads or anything. But not all 7400's can do 4 Ghz that easy. from 2.8 to 3.8 is already a 1,000 MHz overclock on a "cut down" chip so that's a lot.

I'd run 1.440 through it if the cooling is really good (Megatron or lapped TRUE good) and the mobo can control the voltages right. 71.4c should be the max temp in any stress test also, I believe.
