Hi,
I noticed that highering cache voltage helps a lot in stability, also with cache at default frequency.
I increased the cache ratio using offset +0.2v and I set the vcore to 1.250v with a maximum of 1.268

We want to avoid those.

Prime95 28.x and LinX 0.6.5 uses AVX 2.0, previous version of this software uses AVX.

I can "pass" at 4.5GHz 1.275V on the default test, but I'm definitely throttling (only getting 350 Gflops).
My CPU temperature hits 95C+, and over 450 watts flow through the CPU!

I'm never running that crap on my PC again.

does you CPU shutdown at 95c?
my PC shutdown as soon as core temp shows 95c.

No, it didn't shut down. It was throttling though.

I never experienced CPU throttling, my Asus X99 Deluxe shut down the PC at soon as temp is 95c, do you know why?

Maybe a setting in the bios? Or just too unstable?

Maybe CPU current capability, if you exceed the value put in the bios, it will shutdown.

Well, I feel X99 with a 5960X feels like a supercomputer...smile.gif

Makes sense. They are probably the most optimized equations that will take advantage of every part of the CPU possible, and that's why people are seeing performance above 300 gflops. However, with that said, I code numerical models and they don't stress the CPU anything near like LinX does!

But hey, maybe if I get asked why I don't further optimize code, I'll say because I don't want to blow up my 5960x with LinX 0.65 as proof? biggrin.gif

LinX did shut me down but I have no played with CPU overcurrent protection options. That was probably triggered in my case. But I'm glad it was and I have no intention of running something that can pull 450W through the CPU only. While the CPU may throttle to protect itself, I'd be worried about the motherboard.

Even with the throttling you may end up degrading it quickly
