Why do you think most people say dont go over 1.4v for 45nm?

I don't know. :laugh:

I'm going to raise this sucker's voltage until it melts away. I will not go lower then 3,9 ghz, no matter what.:sun:

haha hell yah!

checking that chip in another system that can run at a speed similar to your other setup

yah only real way to make sure.

Here is some help


Im surprised we dont hear more anecdotal evidence of degradation on the Wolfdales from other people that may have pushed over 1.4v for 24/7 use. Maybe we will see a flood of it in the next 12-18 months....

You missed the ironical laughing face from my answer?

I would guess that most people aren't stupid enough to push the voltage beyond 1.4 v in their ocs, so this is why we don't hear anything. But frankly, I was hoping to find at least one or two people on this forum that got this issue.

You missed the homo-erotic tounge sticking out of my smilies mouth? :beer:


I have heard a few stories of degredation, but only 1 or 2 outright killing the chip. This was 1.5v+ though.

It could be worse. At least you are not running it at 1.7V.

Did the voltage in CPU-z change any? On my board I had to increase my vcore from 1.5025 in Bios to 1.5275 due to increasing vdroop (under load).
It's back to rock solid.

Intel did say the voltage limit for these 45nm chips is 1.3625, much lower than the 1.45v most people seem to be subjecting their chips to.

Running your chip at 1.45v is the equivalent of running my 65nm chip at 1.59v and expecting it not to die/age.

This is why I'm hesitant to believe AMD says you can run your 45nm chips at 1.5v.

what is the delta to tjmax for you using realtemp? I'm talking about during linkpack at max memory stressing? I have a E7200 running at 3.5@1.35x, seems to reach pretty high temp during linkpack max stress. I keep the delta to tjmax to about 30C. I also have a S1283 clone (Vendetta 2 for cooling, with the included fan for mine).

1.35v is probably perfectly safe; I'll be you it dips lower at full load in CPU-z.
You're inside Intel's recommendations.

I have had my degradation on all my boxes, and 1.35 is about the max.....

As in, 1.35v is the max before you notice degrading?
I should have disclaimer'd what I said with "**for someone who doesn't fold 24/7"
If I were folding 24/7 I would probably think twice about 1.5v on my current chip.

I'm still running my E6400 from when it was first released at 1.55v vcore at 3.6ghz. I did run into stability problems eventually after 2 years and lowered it to 3.5ghz for stability, but when I swapped out the motherboard I was able to run 3.6ghz again.

Wow, that is a good example of people with more money than sense...

Hmmm, I'm starting to think that this might be true. I've checked the voltage now and it's between 1.39-1.408 V, under load. Now the problem is that I don't remember what it was before this. So, it is really possible for vdroop "to degrade" on a mobo?

If my cheap e7300 dies, I will just replace it

Yeah, but still, it's better for it to live. :laugh:

Yes, did and is reported to do so extensively with a Quad on mine (IP35-E/Pro)

But if you can't hit 4Ghz, that would be reason to believe it is the CPU. I simply increased the voltage a notch and my OC was fine as it had always been..

This sounds like a repeat of "P4 sudden death syndrome".

SNDS - Sudden Northwood Death Syndrome

I remember those days well. I actually was secretly glad that all those awesomely overclocking socket 478 systems failed, because mine (at the time) wouldn't overclock as well. I finally got a great overclocking socket 478 setup... until the motherboard (Albatron 845PE chipset) developed about a dozen leaking/bursting capacitors. Was strangely still stable, but didn't make for a useful computer with network or mouse cutting in and out.

My belief is that a "safe" voltage is +10% because Intel typically specifies voltages at +/-10%.
