ES Xeon Discussion

Thank you very much for clarification.
Do you think this is ES/QS limitations or E5-2650 V3 feature?
Might be a feature despite Ark claiming 2133...
Intel Xeon E5-2600 v3 "Haswell" Processor Review | Microway
- Entry-level “Basic” CPUs now support 1600MHz memory (a 20% increase)
- Mid-level “Standard” CPUs now support 1866MHz memory (a 16% increase)
- Higher-end “Advanced”, “High Core Count” & “Frequency Optimized” CPUs now support up to 4 DIMMs per socket at 2133MHz (a 14% increase)
ES/QS should support the same memory frequencies. The difference between an ES and a QS is in the microcode and the stepping/revisions. Although there are cases where an ES and QS are the same aside from microcode detection. Also ES usually have different clock speeds particularly for turbo boost (usually lower for both).
Thanks for this link on V3 Xeons, it is really very useful, shows why E5-2650 v3 sets DDR4-2133 as 1866.
Would be QFQR on E5-2695 v3 be acceptable or is that too early?
It's one of those intermediate steppings (M0) and I haven't seen a real yay or nay on that one (I believe), the one(s) before it QDXX was a nay , QEY6 (ES2) a maybe (Rollo said yay, Patrick nay) and the one after it QFQG (PreQS) a yay though...
I though I had seen a CPU-Z screenshot in an old ebay listing which showed it as Pre-QS but cant find it any more.

incase anyones interested my X99-UD4P , E5 2685 V3 ES and 16gb of G-Skill DDR4 Ram are on ebay uk. going with X79 and some cheaper v1/v2 Xeons for a play 
Have you or anyone ordered off this site/seller? Seems pretty hard when you can't read Chinese, even with google translator.
If its the final QS stepping then it should work as those are identical to production levels.
Well the screenshot is up, its Stepping 2 /R2 .. so i'd assume its not too bad. On the other hand there are severla steppings after it so they found some more issues... Decisions decisions
That's the same one as a production processor. Haswell-E/EP all use Stepping 2. R2 is incorrect as CPU-Z reads it when it probably means Revision 2. The actual stepping for Haswell-EP processors such as the E5-2683 V3 are C1. So the revision is correct and if you see Stepping or Revision 2 it is either QS or pre-QS/ES. You may have also noticed some ES Haswell-EP processors have a Stepping or Revision of 1. Those are the first samples and likely B stepping processors.Well the screenshot is up, its Stepping 2 /R2 .. so i'd assume its not too bad.

Mistertao is taking 8% commission.
By the way , xtrememicro refunded my order on the xeon e5 2686v3 qs and told me they have oversold, did it happened to you too?
I can't say that I am surprised about them overselling the E5-2686 V3 QS. They recently had the E5-2630 V4 ES (R0) with many in-stock and then kept revising the quantity down to 2. I wonder if whomever bought 2 of those processors were probably refunded as well. Xtrememicro still has yet to respond as to when they are getting more 2630 V4 or even 2686 V3 QS.
Finally it's here ,

Ordered 2-xeon 2673 v3 QS and got 2676 v3 QS = 649.35 $
Supermicro x10drl-i = 376.62$
Crucial 64gb ddr4 = 333.77$
evga gtx 1060 ftw+ acx3.0 6gb = 337.66 $ (on the way, now using 7970)
2- hyper-t4 = 87.27 $
crucial mx300 275 GB = 77.59$
1 tb wd blue = 46.28$
Power supply corsair rm850x = 163.36$
corsair 100r case = 58.54$ (swapped old computer case cm storm trooper)
cinebench r15 ≈ 3042cb

I picked up 2 E5-2689 QS. I could have got the retail for about 26% more but most dealers told me they were identical. It has same stepping and everything. Now, my understanding was this mode would do 3.7 all core and Turbo to 3.8. And that is what I am seeing and I am seeing overall nominal benchmarks and in-line with spec.
However, when I run Corona Benchmark then I see the CPU throttle down to 3.2/3.3ghz and my real speed is only 3.2 to 3.5 vs 3.7. My temps are still reporting below 70C but challenging it. So if I'm seeing anything less then 3.7 all core does that mean the chip is heat throttling or is there another kind of throttling TDP throttling? I am running NH-i4 cooler. The CPU monitors do not report heating throttling. But, it seems to throttle at 55c to 60c.
It appears to be heat throttling but should this cooler be sufficient for this chip? Or maybe the paste hasn't set yet. Any recommendations for a good solid cooler that will do the job if this one doesn't? Maybe h100?

Are those V4? Because in V4, intel introduced some kind of stupid protection when using AVX, where the chips throttle down even under normal temperatures. Since Corona uses AVX, numerous people with retail V4 chips have written on their forum that they get less performance than their V3 systems.
So if your system is for rendering, wait and hope for intel to fix this somehow.
It is not for rendering. But, I have other benchmarks too where it shows my CPU averaging 3.5ghz but the others averaging 3.7ghz or the turbo turned offed. My overall speeds are good but not sure why seeing this behavior. I don't really hear the fans kick into any sort of higher gear either.
I have the ASUS Z10PE-W16. Perhaps someone can show me how its suppose to be setup? Most of the features aren't explained. One thing I noted is that this CPU has an operating temp 55C compared to the 2687wV4 of 70C @ CPUWORLD.
But thanks it sounds like it could be due to the AVX instructions.
