ATM, I'm not a huge supporter of x264; it was able to find a fair few instabilities as I established a baseline voltage, but its certainly not intensive enough to find all instabilities (i know it's not synthetic).

I've had to bump .03v to achieve some sense of stability on OCCT whereas I was fine in x264 without that extra voltage. I think that's fairly significant and can't be within margin of error

Try Y-Cruncher, it would give your chip a run of its life.

Edit: Checking, bluescreenview etc; it was a 124 - but it was just like a soft restart, didn't throw bluescreen, i've only seen that happen when very close to stable but missing a tiny bit of vcore

Ah yep, makes sense smile.gif

Awwwwww yisssss. What's the heat output on it like?

Aha!

finally at the desktop at 4700mHz @ 1.3v.

It's late though. Stress testing tomorrow.

As it tests different parts of the processor for stability, I think after it tests the CPU cache (uncore), it also tests the AVX2.0 instruction set and during that, temps can jump 7-10C. So it can get it a bit toasty, but not consistently.

Ill give it a crack tomorrow when my 30 passes of x264 are done. Thanks smile.gif

seems a bit excessive, that's what, 5 hours?

If it doesn't work, it'll not work faster than that i think. Doing a ton of time on a hard stability test is good; i've yet to pass an hour of x264 and be unstable in any game or while encoding stuff though; if i was it's just a matter of slight tweaks - if x264 misses it, it'll probably miss it given 1 hour or 5

I got a 124 error on the 17th pass of x264 on my old 4770k wink.gif

Yeah, about 5hrs haha

To be honest at that point i'd just leave it and add +0.01vcore if any sign of instability showed

Yeah that's fair enough. Honestly I have nothing to do until the Ti Classy arrives next week so I figured I may as well go crazy with stress tests tongue.gif

That card has some sex in it man!
