Does extreme benching cause degrading? - Page 2

I checked, I think it did 6.3 @ 1.84 with 2 cores.

I dont think batch means anything with Ivy + degraded.

Biggest lottery.

Also OC ablity on LN2 tells you nothing about the OC ability on air/water wink.gif

Just to correct a common issue.

Voltage does NOT cause degradation.
Instead the increase in voltage also increases the amperage drawn, and because of this, the increased amperage can burn out or damage traces.

For voltage to cause degradation the voltage would have to get high enough to cause internal arc-ing from trace to trace. And although the transistors are small, that and quantum tunneling are not occuring at this voltage range. tongue.gif

Ivy Bridge is a super resilient CPU arch, so far they have been hard to kill or degrade given you're not a complete idiot and know what you're doing. I've had chips up to 1.94v, nothing wrong with them, work the same on water as they did before 1.94v on LN2. So generally speaking, degradation would be my last guess at what is wrong here.

As for your golden assumption, as far as I know there is no golden batches with Ivy, it seems to be just like Sandy, all in a lucky dip. 6.3 is pretty average for a 3770k on LN2, my first 3770k does 6.5, 6.6+ is getting into the good range of cpus.

Yeah batch seems minimal.
However we are seeing degradation plenty with Ln2. Quite a bit actually. Most of the time you see it in HT on situations where the extra internal head load is causing damage even through the cooling.

Some info from the -220C LHe crew was saying that the chips are garbage and won't hold stock @ stock volts after going down that low. But they do a different gig entirely.

The issue with extreme overclocking is that there is no standard source of information and no professional standard for testing, all you have to go off is your own experiences. There's always somebody who knows some group somewhere who is more knowledgeable than your tiny self. Not a shot at you NoL at all, just a general observation I've picked up on.

Anyway, I talk to and bench with a few overclockers and so far from what I've been seeing the chip is either alive or dead. I've seen and had cpus just die on me after or during a session but I can't say I've actually experienced degradation yet, and I was quite liberal with volts with some of the chips.

Oh of course, even the little things like what power supply can be largely responsible at that level.
LHe @ -228C though, they said no gains past 1.98vcore, and was pulling ALOT of power. Now with water to pull stock speed takes 1.42 vcore.

I can confirm both of this. Have pushed 1.93v through several Ivy Chips and none of them has taken any damage or degraded, a friend of mine even pushed 2.13v with a MSI modded bios IIRC and the chip still lives and works like a charm. No gain over 2v or so there to.

1.45-1.5 24/7 it is then smile.gif
