EDIT: It was in adaptive mode with turbo voltage set to 1.275 and offset set to 0 where it spiked for no good reason

I'm sitting at manual vcore of 1.20v for 4.0Ghz, which Is probably more than required. But I like to run a processor in for a few weeks to make sure no BSODs occur, and monitor thermals. I don't trust Prime 95 anymore, even when I've had systems that were several hours stable in that tool, i've had BSOD's. It's a waste of space that program imho...I just don't think it's reliable anymore with multicore CPU's of today.

My current method seems to be far more reliable, 32M SuperPI 2 or 3 times Cinebench R15 several times, Game for hours, multiple Firestrike Ultra runs. And my 5960X @ 4.5Ghz never once failed me. If I relied on Prime 95 for stability i'd be pulling my hair out.

My philosophy is that the CPU should run anything that's thrown at it. The negative AVX offset really helps these CPUs. Prime95 AVX on small FFTs serves as a worst case scenario for me.

I also run older versions of Prime95 and Linpack to test my non-AVX overclock, as well as ASUS Realbench and Cinebench.

Negative AVX offset only helps if the PCU applied voltages are sufficient for the AVX ratio and the normal use ratios. If one side needs and offset and the other doesn't, the usefulness of this feature is very limited.

Right now I'm using it mostly to limit thermals. Small FFTs with an AVX enabled Prime95 at 1.244 V gives me ~82 C on my hottest core at 4.1 GHz. Is that a reasonable usage for the offset?
post #415 of 7480
Depends if the voltage applied is close to what the CPU needs to be stable at that frequency, while not affecting requirements at the normal ratios. That's the rub; the fact you cannot tune voltage for all CPUs effectively for both scenarios. If your CPU can run with less voltage and you apply the offset, it will affect the normal ratio voltage, also.

AVX small FFTs... why are you running this? Need to test the heat flux of your cooler mount?
p95 sm ffts have not been useful as a diagnostic of instability for quite some time. Are you setting up a computational box?

AFAIK, you need to leave voltage control on Auto for this to work. Just OC "by specific core" or synch all cores. Use the AVX offset if needed.

True, p95 small ffts with the most recent version (28.7) is the worst. tongue.gif

Can you find a public source for that? Cause I can't, I may have said too much biggrin.gif

Not wanting to read through 40 pages of this thread - anyone that has been following, has anyone managed to get a stable OC past 4.4 on the 6800k?
I'm using the Asus OC built into the Rog Strix board and the 4.4 OC setting is stable and runs about 70-80 degrees under full load rendering movies.
I tried to bump it to 4.5 and BSOD.
Side note - my MSI GTX 1080 comes in today!
