13hrs Prime95 stable...apparently isn't stable - Page 3

So If you're not using any LLC setting, or a very low one, the opposite could happen, and make IBT/AVX unstable. Even if this was true, your computer would never crash in anything else, as long as you where Blend stable. This is because nothing else, except IBT/AVX would drop Load Vcore lower than Blend.

LLC is disabled because of the sleep/resume issue. Until they fix that I won't enable LLC, unless there's another fix.

My Blend test was 12+hrs stable, but still crashed when encoding. It also crashed after 1 IBT run.

Has LLC something to do with the Sleep feature? I thought it was the Internal PLL Overvoltage when enabled that affected Hibernate.

Also, alot of us have to disable C3/C6 to avoid idle/light load BSOD when using Offset Vcore.

Blend does indeed consist of small and large fft. However, unlike the small and large fft tests, blend uses 1600mb of ram by default. If you just choose small ffts and click run it will use no ram; if you choose large ffts and click run it will use 8mb of ram. Now if you choose blend and click run it will use 1600mb of ram, making it a better overall stability test than either of the other two.

sorry my mistake, i was confusing the two. remind me what LLC is?

any downside to disabling C3/C6?

There is a much better free stability program than intel burn with avx which is TOO stressful, and prime 95, which doesnt cause blue screen fast enough,

its called Team Fortress 2 32 man bot match

I tested my 2500k with many programs, including ludicrous 12+ hour prime and 100 pass avx intel burn test, but tf2 causes blue screen in usually less than 2 hours, and without heating up the processor to 70+c.

Nice. Good to know.
So what is it actually doing with the RAM that is being used in the blend test?
What sort of test is running on it?

LLC is the Load Line Calibration. Helps stabilize the Vdrop. At Ultra high the Vdrop would be minimal.

Disabling C3/C6 only gives a tad higher Idle Vcore. This helps to remedy the idle/light load BSOD's.

i'll try dropping the vcore back to where P95 was stable and enabling LLC to see if that makes a diff.

Are you getting insane temps with IBT/AVX? I know it runs about 10C higher than Prime95. So If your temps are getting insane that could BSOD it.

Personally I find Blend to be a better stability test. I find IBT/AVX is only producing unrealistic heat and not so good for stability testing.
