Do you know the maximum voltage for the E8400 that is safe?

I heard 1.38v was the max safe voltage to run 24/7, but personally I would not set my voltage over 1.36 as Aleir suggested ( if I had an E8400 anyway.)

First post here, I've a E8500 waiting at home but I don't know if it's a C0 or E0, so I was wondering if anyone has been playing around with P5E0903.
I'll fill in my system at home this weekend, P5E BIOS RF0403, Q6700 at 3.5, 4x1 Patriot PC29600 at 1120 5-5-5-15 , Air Cooled

Actually, the Intel datasheet specifies 1.45v as maximum E8400 voltage. I have personally taken an E8400 to 1.5v on air for a suicide run, and I've seen others do the same. 1.40v is what I would recommend as a max if you have good aftermarket cooling (top air or liquid). I run 1.40v for 4.23GHz 24/7.

You can find the Intel datasheet HERE.

Interesting. I was able to OC my E8400 to 4.3 with 1.38 vcore and I thought theres lots of room for higher OCs and low vcores. But when i wanted to go to 4.5 with vcore at 1.45 I was unable to load in Windows. Strange that you need such a higher vcore for 200Mhz higher frequency.

Sometimes you just hit a point where the clocks don't scale with voltage.

I know the spec sheet says it can go up to that, but wasnt 1.4v and above causing many E8400 chips to "kick the bucket" prematurely? Im not sure if there are newer chips out that can withstand higher voltages but from what I recall there were many people that were burnin chips.
How long have you guys your had your CPU at 1.4v for 24/7?

There was a lot of talk about the so-called "degradation" but a lot of people on XS did a lot of testing and found that it was more of a "burn-in" period. Also, people were going crazy with PLL voltage and FSB Term volts and stuff, when these chips don't need them to be that high.

My chip is actually a pretty early batch (Q740A553). I haven't had mine for very long, because I just bought it, but the guy who had it before me was also running it with water cooling at pretty much the same volts 24/7.

Anyway, we'll see how long it lasts.
