That was exactly what I mean, you can pass a few stress tests & still be unstable in other uses. Stress testing doesn't really mean stability, you have to throw a bit of everything at it including the things that the rig is used for.
Prime 95 24 hours may not stand up to a good day in bf3, bf3 stable may not pass when encoding.
Stress testing for a starting point & then making sure it can do everything you do daily without crashing is stable.

If you're really after stable, you really have to throw some of everything at the cpu.

I had the behavior described on my Ivy Bridge CPU. prime95 blend ran for over 20 hours without error, but the PC wasn't completely stable afterwards. There were very rare program crashes and WHEA-Logger warnings over the following week. It needed more vcore to get that fixed compared to what prime95 needed.

Agreed, good advice. Try use stress loads as closely matching your heaviest use possible. Too many variables to be definitive.

Umm yes it does because the XTU benchmark is Prime95. biggrin.gif

Prime95 does a great job at validating if your cpu is stable if you are overclocking. It's definitely a good idea to test some gaming and x264 encoding as well. Or whatever else you use your computer for.

It runs it a bit differently though, instead of taking xx hours to go through all the FFT sizes it throws some of everything at it hard & fast, like a condensed prime95 run, not as extensive in testing, but takes minutes.

hmm....well guys.

So Ive been running AIDA64 for 8 hours and 15min. As I did mention a few pages back. And then someone said "aida64 not good...bla....use prime95...bla bla......."

So because I am who I am (which means being extreme stubborn) I'm now gonna run prime95 27.9. The 3 first tests 7-8hours each.
You can laugh at me now if you want.

But I'll return in 1½ day providing an new update. Which I assume will be a 100% pass prime95 too.

When I return, its time for gaming stresstesting and daily use.

Nobody will laugh at you for whatever you use or however long you use it, it is relative to your use. People are here to try help or advise.

Running a less stressful version of prime and playing bf3 in a window at the same time lol , empty server though.

In offset mode what makes the voltage 1.312v spikes to 1.44v ?

If you are running an AVX-type load, the chip will increase the VID, and offset is added to that, so that's why it is spiking. At least in that instance.

So those spikes on load is normal or any settings that need to be change to stop the volt spikes

I notice it in ibt
