e8400 Stable enough? - Page 2

post #11 of 23
It's been suggested by some that at voltages below 1.45v or so, degridation will be limited to .05v. So, I'm running an experiment.

If a week of small FTTs at ~1.4v in 35C ambent temps doesn't kill this chip, or degrade it beyond needing .05v extra, then I'll consider this theory to be tentative fact.

Otherwise, I'll have a dead chip. Sometimes risks must be taken in the pursuit of knowledge (and higher overclocks).

I've been running past 1.3625v for roughtly a week now, and have experienced some minor degridation (a hundredth of a volt). Now I'm seeing if it stops were predicted.

Well, something like 1.301v is fine, just don't go over 1.31v.
Even though it's stable and cool, that doesn't mean the chip won't burn. 45nm is really sensitive.
Not true. Who says that.

If that was a xeon 3110 chip i'd say over 1.4v would be risky but not for a
e8400.

I have been running my chip at 1.41v at 4.15 ghz for the last 2 months and had no issues at all.

Good luck with it. I can't swing another cpu so 1.36 is my self-imposed limit.

Lmao, we're starting a voltage fight.

Anyways, if you guys like running your E8400's at 1.4v+, go ahead.

I see no harm having 1.36v

1.4 is pushing it,

1.45v + you're asking for trouble.

Hassassin, there are tons of guys on here with 1.36v and they have no problems whatsoever...

do you even own an e8400?

Running 1.4 at 4.3 as we speak. I go up and down and switch clock speeds and what not a lot. 0 degrading or anything. 4.3 at 1.4 isnt prime stable for long, but it is 100% stable when using the pc at 100% load so.. fine with me. Prime + 45nm = weird.

Yes I do own an E8400.
Anyways, as I said before, chips are different. Yours may run at 1.36v no problems but someone elses may not.

Any totally stable x86 chip should beable to pass nigh infinite runs of Prime95 without errors, and my goal is 100% stability, even in less than ideal conditions.

Ah yea of course, I can run 1.3 100% prime stable, maybe lower even, and 4.2 at 1.36 fine.
I usually like prime stable, but with these chips, non prime stable doesn't cause any problems. On 65nm I only will do 100% stable.

I ran my e8400 for 2 months at 1.36 and no problems. 4.3 stable, I am currently at 1.37 with my qx9650. I might just might go 1.40 with it.
