Yeah, have been using it since day one (Version 0801).
Lowering the VCCIO to 1.1v threw out the x265 run bigtime, got a invalid run when using 1.05v, where with Auto it was fine.

So, looks like some board models need a higher VCCIO, no big deal. Run the Auto setting if it works. I have to DL the manual for that board, doe the bios have a Tweakers menu?

Went back to Auto VCCIO, got closer x265 results (All within 1FPS).

The board has a "Tweakers Paradise" section:






I posted what I found with the Aura software over there when I first came across the problem of it lowering benchmark results/performance when installed.
But will keep posting new findings like the high VCCIO as well..

Ah.. missed it skimming the manual... try this and gradually lower VCCIO:

But more importantly, just realize that running a 6950X for a long time, eg 24/7 at >1.35V and higher is pretty much uncharted territory.

shoot for 4.3/3/7, solidify the ram OC and build from there. smile.gif

not uncharted territory

but my thermal limit hits around 1.385V when using the stress tests OP was using, non AVX stress tests around 1.41V.

I'm alright with input at about 1.94V, but prob need anywhere in that range up to 2V

I don't use adaptive voltage/SVID supports so this skews it.. but I definitely need over 1.375V for 4.4GHz to work on multiple 6950Xs on mprime/aida/etc. - but have to lower the cache to avoid hitting max temps and throttling.


side note: anyone know where I can find some in depth info on overclocking with ln2/alternative cooling methods? I found some stuff by Gigabyte which was helpful but would really like to soak in more info on it.

the chip has been out for only a few weeks .. so it's uncharted territory for 24/7.

Low latency is good and for gaming, I doubt you would notice any difference between 2400c10 and 3200c14. As an FYI, the GSkill 3200c14 8GB sticks are Samsung ICs, Hynix is fine and I ran my Hynix kit for a long time at 3200c15 or 3000c13... let us know how the VSA adjustment works out.
did you flash it to the most recent bios for that board?

I used to be of this school of thought....I had 2666mhz C12 instead of 3000mhz c15.

Frametimes were better with 3000mhz. Much more consistent. There's a write up about this somewhere.....

bandwidth also has a large influence on the true latency. Those 2 kits latency would only have a difference of like ~5% and would be barely noticeable.

That 5% got me noticeable frametime increases in The Division.

Very noticeable in fact.

This is a really random question but;

Does anyone know why some software won't read/register my CPU properly? Is it just because it's so new? I'm using the 6950X. NZXT's CAM software can display the name of the CPU, but doesn't show the temperature. Speccy only shows "Intel Processor @ 3.0GHz" and doesn't have a temperature read out either. My motherboard is the ASUS Rampage V Edition 10, so, BW-E was/is supported out of the box. So I don't believe it's that it needs a BIOS update. And the temperature sensor works, as in BIOS I can see CPU temperature.
