Try doing an x265 encode and monitor clock rate.

CPU: i7-5820K @ Core, 4.3Ghz (-0.08V/1.33V Adaptive = 1.25V); Cache: 3.9GHz (1.20V); VCCIN: 1.85V @ LLC 6 12hr x265 (AVX2) Stable
CPU: i7-6950X @ Core, 4.2Ghz (+0.01V Offset = 1.30V); Cache: 3.3GHz (1.05V); VCCIN: 1.90V @ LLC 5 12hr x265 (AVX2) Stable

Hi,
Use Blender and classroom or BMW demo rendering file
It will throw a little avx at you bmw being the short test about 3 minutes and classroom about 9 minutes
https://www.blender.org/

https://www.blender.org/download/demo-files/

Use hwinfo to see if you clocks drop the amount of avx you're set at.

Oh, I was only talking about stability here, sorry for that misunderstanding - I understood it so that you meant that fluctuation between AVX and non-AVX clocks hampers stability.

Sure, intermittent AVX load leads to corresponding frequency fluctuations.

Hi guys,
i've pushed my 6950x a little bit further.
Reached 4.3GHz with 1.26V on the Core. Don't want to go near or beyond 1.3V core voltage.
While i was testing i got two times BSOD 0x101 and i cranked up the vrin to 1.92V @ LLC5.
The issue is gone.
Do you think 1.92V is save or is it a little bit too high?

Too high. 100MHz aint worth it. If you REALLY want the sweet single core performance I suggest you start looking to per core OC and leverage the Intel Turbo Boost Max 3.0 application. Set your best core to 4.3GHz and all other cores to 4.2GHz.

You mean that vcore @ 1.26V is to high, right? Realy? My question was if vinput=vrin @ 1.92V LLC5 is to high.

Is it worth it to upgrade a Haswell-E to a Broadwell-E? What's the diff in IPC? Do Broadwell-E's overclock better as to core or IMC?

I think it was 6% better IPC. But they don't reach the overclock level like Haswell-e. 4.5 Ghz on the cores is mostly impossible. The IMC is better as Haswell-e

Probably not unless you want some extra cores and would rather buy the newer chip, but they definitely dont clock as high and the cache doesn't get anywhere near the core clock like it did on Haswell-e
