I'll go out on a limb here but...

Dropping vrin and raising vcore will be counter productive unless you're out in the middle of no-mans land. If it does work for you then fantastic and i need to go have a play about with that myself/learn something new!
Adjusting vrin by .05v is too much for one step, especially when you know you're close to stability.
x264 isn't the be all/end all for stability, it is however a useful tool for doing the ground work. That's why i strongly suggested using XTU after x264.....Even then i quite openly admit that won't get you P95 stable. (back to the 'whatever floats you're boat' for 'level' of stability)

Trying to get things done too fast and cutting corners may not achieve the desired outcome....

Anyway, i'm sure you'll figure things out. I'm just wiping by brow that the chip you got is a good one or i would have felt pretty bad!thumb.gif

It was just a quick test there, as i told you before no stress test mean anything to me since my only concern is to be stable at the mother of all stress tests, 24/7 folding. Then i call it success wink.gif More testing to be done, countless bsod to follow tongue.gif

If you are reffering to me then i have to point you the first core at 78C, which means if i want to go higher i have to delid, since running 24/7 at 100% load with 80+C is not ideal to me, see i m used to me previous delided 3770K folding at 4.7Ghz@1.33v at 55C max biggrin.gif

Certainly nothing better than folding for stability testing, glad that someone else also thinks the same. And here folks counting passes on x264, xtu and some stupid crappy stability test, lol.

Didn't we agree XTU stability test (not the bench) is close to useless, almost or similar to AIDA64? It doesn't do anything worthwhile re: stability and unless you've got vcore way higher than needed to pass that XTU it almost guarantees you'll fail BF3/BF4.

x264, the executable provided by the bench is very old, there's been more than +150 revisions to it since but you can easily update it yourself, it raised temps slightly and increased FPS for me.

It's an each to your own kind of thing. You stress with what you see fit and get stability. My personal choices are x264 and prime95 27.9

Has anybody here experience "CPU break in"? In other words...you buy your new CPU, find a stable OC within the first week....then possibly 3-4 weeks later, it becomes unstable and requires more voltage?

Some people have over here, as you go through the threads, it is possible. I mainly think that its because of the high temp spikes that causes this of an undelidded processor.

But I personally think that if you've stressed tested the CPU enough to know it being stable at a certain VCore, VRIN, etc, then that certainly shouldn't happen (at least not till a year or so).

I found it pretty hard to validate stability, a few things are good for hard checking like avx2 linpack for vcore, but it's not practical to run them at high clocks, it usually comes down to a few slight vcore bumps for me over time and then no signs of instability.

Unless you have the same board - same bios version, and a list of settings that you wrote down that you can set after resetting bios to default settings, before you run the same version of the same program etc that you never failed with a lot of runs, and then fail it - you can't really say the chip degraded IMO. I got quite a few freak passes with Haswell like ibt+avx 10xstandard with 1.155vcore when it's not even stable in LoL until a touch past 1.2 on that multi

So that x264 loop from pastebin seemed to...well...stop looping after a few hours. IIRC, loop 20 out of 20...is that right? It was under the impression it would run indefinitely.

It only loops 20 times. If you want one that can loop indefinitely, I'll work on it. Just gotta get off work.

1 quicker one and 19 of the heavier ones, yeah.

You can of course change the batch file yourself easily enough and copy/paste another 19 lines if you want.. or just kick it off again as-is.
