post #11041 of 19540
System is stable at 4.6 with a cache clock of 4.4 on 1.3 VID/1.32 Vcore.

There is definitely more in it. But I´m going to delid next week and save the bigger OCs for after. Cause my chip is running to 90°C on a custom waterloop with 1.32 already. So I´ll have to remount either way and so I´m going for the delid in the process. Already ordered a bunch of 3€ Core Duos to pratice on thumb.gif

1.33 on the ring? I'm not sure how much heat that adds vs like 1.1v but it's just not worth it unless you're at like 1.4vcore and don't want to add more to core voltage. If there's headroom there, you'll probably get more performance from increasing that instead of getting that last 500mhz out of cache for 0.2v.

I found no major difference in temps or average temps going from the very original x264 vs your new one. Average CPU usage went up, but temps stayed same.

Also, why doesn't everyone use the latest Prime95, just tell it not to use the really hated FMA3? There are some fixes/improvements for AVX in the latest versions.

I’ve said this some time back and nobody found it pertinent (even though some of you faced it personally),

I found through experience, that i could pass under a certain voltage 2 hours of prime small fft’s and 2 more on large 1344, 30 min of IBT very high and 10 loops of x264 test, BUT i bsod’ed while encoding a bluray with megui after 2h:45m (just 20min before completion).
And i verified this with a different video (this time with vidcoder) that bsod’ed after 2h:20m ( just 5 min before the estimated eta)


Some of you faced this aswell, when you complained that you crashed under BF4 after you passed 30 min of prime or 10 loops of x264 or whatever else. I’m pretty certain you didn’t crash after 2 min of bf4, rather after couple of hours.

Stressing with prime fo 30-60 min or IBT at very high for 20 min it’s not enough!, it’s a necessary step but not enough. Longevity of your preferred test is the last thing you have to address before you can qualify your OC as stable.

Therefore, through my experience i’m slightly inclined to believe that the x264 stress tests you’ll find through this pages (including the original x264 benchmark), despite my attempt to make it as stressful on the cpu as possible, is not the best tool to confirm the final OC stability.
And i suspect that is, because of the 1 or 2 seconds of “leasure” the cpu gets between the loops.
Use it as a stress test to determine your cpu capabilities alongside prime, but, as a final personal validation of the stability, use something (x264 continuous encode, battlefield 4 (or whatever games use avx instructions) etc) that last more then 3 hours.

Wait, i'm confused. So you crashed while encoding a bluray with x264, and you're saying that x264 is not a good stability test?*

In general i tend to add a little voltage because in my experience when using oc's for days or weeks you tend to eventually get bitten in the ass by this with haswell


*I'm thinking either you're just running far longer in these cases and running into error eventually because it's not really stable (option A) orrrr.. some usage of the encoder is more stressful the way you're using it. Either way, both is fixed by just overnight x264-ing then adding 0.01vcore, no? If the stress difference is enough for +0.01vcore to still crash, i think we can obviously improve test further - but i don't think it is. Current version is pretty mean on CPU

That’s true, i only get 2° higher with mine than on original, which is within the margin of error.
But it is the same as what i get with megui, so it’s probably closer to real world results.
Yet, it’s still the hottest non-synthetic application that i tested, 10-15° over the hottest games, while the cpu usage is closer to prime than games or other everyday applications.
Anyway, we have prime and ibt to test the temp headroom of the cpu.

IBT is using old version of linpack, no version of prime is as hot as linpack that's not two years old tongue.gif

No, you misunderstood, i said that x264 regular encoding found instability where the x264 stress test/benchmark that we’re using didn’t..., and that i suspect is because of the “time off” the cpu gets between the loops.

Whatever encode i do with megui or vidcoder for personal uses is nowhere near as stressful on the cpu as the x264 stress test that i provided is...

Well, that’s what i did, i increased the voltage. But my point was that the x264 stress test/benchmark might not find the instability because of the pause it gets every 10m or so between loops.

LinX then.., it’s almost 10 degrees hotter than IBT on my system.

But all this super high temp tests are only useful to determine one’s cooling solution capabilities.
I can’t imagine there will ever be an every day application that heat’s up the cpu like prime small fft’s does, let alone linx.

EDIT.

Very high temps will bring small instabilities and require a little more voltage, that's true. But very few of us reach these very high temps in every day use to deem these very high temp tests an absolute necessity (unless you have inadequate cooling in which case you don’t need linx to get there)

I tried 1.3 Vcor with 1.1 Vring and there is no difference in temps at all, for some reason they even seem to be higher (maybe due to ambient)

I always thought the the ring voltage should be around 0.02 lower than the core voltage. and 1.3 being the maximum. I set mine to 1.3 in the bios.

But as I said, I think there still is some room to improve the tuning and all.

Going much higher an the Vcore is not possible at the moment. with 1.35 the temos go to 100°C. That´s the reason I´m aiming gor the delid

I´m going to tweak it now with a lower cache clock and lower overall voltage.

There shouldn´t be that much of a difference performance vise
