Hey man, I know it might be hard to believe that I got this used from ebay but I truly did. If I knew where the golden batches were I would let everyone know. If you want I can PM you a link to the auction but I do not feel it would be right to post it publicly.

I reseated the cooler and reset my bios and manually put my OC settings back in as well as loosening my ram timings. I realized that the core stopped again after browsing through a few web pages so I started it over leaving it alone and it passed. So it appears 1.392v was stable but web browsing made a core stop.

For those with Gigabyte UD4 B3 1155 MB's F3 bios is available and CPUZ has a new release which shows the vcore accurately.

So you increased vcore 1 notch and got the same temps as before?

1.392 to 1.404v is not much of a jump.... I know resetting my cooler helped a touch...

I should rerun it since a core got scrolled or something not giving definite proof of my claims.... I know it passed though... rerun or not... ??

Jason, you ran for 23 hours, right?

There's no need to get OCD about running tests. Just leave it as it is and call it a day. I doubt you'll find any normal program that will crash. Go ahead and try to play some games on it and see how it works. If you keep trying to prime, you're going to eventually suffer from "Break-in"/"Degradation."

I wouldn't keep that as a 24/7 speed, though. Someone who had been folding about 2 months at 5 ghz, 24/7 (water cooled; temps were not a problem) said that after 2 months, his CPU stopped being stable above 4.6 ghz.

my 2600K is having trouble even folding stable above 4.6 now. A few months of folding at 5 and 1.52v seems to have taken its toll. On water here so temps shouldn't be a problem. But hey I knew the risks. I regret nothing! lol

If you keep running tests, you will find that eventually the CPU won't pass anymore and you'll have to raise the vcore. It's called "break-in"; I'll refrain from calling it degradation because some CPU's will lose their absolute maximum clocks/absolute minimum required vcores right on the very first run, even at very low voltages. C_N's 2500k, for example, booted into windows on the very first run at 1.29v @ 5 ghz, then on the very next boot, it BSOD and needed 1.31v to make it in. Then about an hour later, 1.33v. Eventually it settled on 1.35v and was stable from there (yes, it was a godly 2500k).

Basically the difference between break-in and degradation is, breakin is when the cpu will need a small bump in vcore, from its max clocks (at a certain vcore) when brand new, and it won't matter what the vcore is or what the clocks are....it can happen at 4.5 ghz and 1.25v. These CPU's eventually settle and will stop needing more vcore. Degradation is when you run at high loads/high vcores for a long time, and then are no longer stable. Yes, I know, they are the same thing basically, but one is pretty much unavoidable while the other is avoidable.

Ok, for the TL;DR version, just set a profile for the high end gaming settings, set a second one for 0.025v less with Hyperthreading off, and call it a day. And just keep your CPU around 4.5 ghz and 1.25v (load vcore) for 24/7 and you'll be fine.

No, I am only running 1 hour blend.
This is a new chip to me and I need to spend more time refining my OC. These p95 runs are being somewhat elusive in reporting errors.

I have never experienced cpu degradation before with all the cpu's and platforms that I have OC'ed. I do believe it is possible but I highly doubt I will experience it.

nice chip.

It seems like most of the malay were B, some A, and rarely a C.

Do all the costa chips seem to be A batches?

Technically speaking this is true. Low input produces higher load output and vice versa.

Based from that, higher load output produces higher temps.

Please don't ask me why I know this. All I know is this is one of the basic principles in electronics.

Problem is, you have to know what the "input" is. It isn't directly CPU core voltage, since in that case, the higher you raise the vcore, the cooler the chip should run....

You're not referring to Ohms law, or Watts=volts x amps, right?

Might be something related to resistance...
I don't know...someone said lower VID chips react better to voltage since the walls are thinner, but this also lets more heat escape as well. Higher VID chips=thicker walls=doesn't respond as well to voltage=runs cooler since the walls don't release as much heat, since more vcore is needed to push current through the thicker walls ...oh I don't know...
