How far is too far? (E8400 C0)

post #1 of 50
Thread Starter 
I am happy to finally have reached 4ghz, this is a first for me. It feels great. But my temps are excellent and even though I had to push the voltage to the dickens for stability, how far can I go on the vcore? I am only looking to keep this cpu for a year tops, most likely til Christmas when I'll finally go Core i7.

Is 1.5v safe if the temps are <60c load? Whats the max benchable voltage?

Is what I am currently running.

I am not trying to get the max life out of this chip, only the max OC.

Well thats pretty bad for just 4ghz ahaha, but seriously though, I have been trying to get to 4.4ghz and i cant get it stable, I have my voltage as high as 1.5 and for giggles i tried Intel burn test.....ya I saw 90c on that run LOL!

I put my cpu through hell and she is still kickin

The vcore is higher than Intel specifies, but if you can keep the cpu cool or below 72C you should be fine. CPU degradation can be a possibility if the voltage is too high for too long. Several people have proven it.
I don't want to say your safe for a year, but if the cpu price doesn't bother you much it would be a good experiment for all.
What temps does the cpu reach after a few hours gaming?

Maybe you can lower the vcore to 1.4 and kick up the chipset voltages a notch or two to help stabilize.

Keep your vcore at one increment over 1.3625 and you should be fine.

It's a C0 so it might be a bit tough.

For benching 1.5v is perfectly acceptable in my opinion I've seen some extreme OCN benches pushing 1.59vcore through them. Just keep an eye on the temps because pushing voltage that high makes a watercooling investment become worthwhile .

Well I tried for 4.0 and Had to bump up all my voltages. I ended up bring it back to stock voltages at 3.825Mhz and 200Mhz wont kill me and I most likely wont notice any performance drops except in maybe benchmarking......but who cares about my bench scores if i can game at very fast FPS

Obviously he does or he wouldn't have made this thread. Some people enjoy benching.

I am thinking 1.5v 24/7 and 1.6v benching.

Honestly, if this chip dies tomorrow, no big. BUT if I can keep it for a year or 10 months, then thats $150 or so I can make off my backup Q6600.

I am actually still getting some freezing when installing games while browsing/downloading 3dmarks/watching movies even though it passed 19 hours orthos. Is freezing a sign of too much voltage?

My NB is at its max in bios, 1.45v. My SPP isnt, however. I dont think 1790FSB is a big deal for a 750i ftw.

For benching, I always just keep turning up voltage until I don't get a post. Never had any problems killing chips. You run into problems when you go up by increments that are too large.
