I wouldn’t overclock the ES cpu’s
Someone correct me if I’m wrong but they been stressed already to the max.
And we don’t know what kind of minerals /material they made of. The word is going out that there made out of cheaper materials. They were made for testing purposes only.
So I wouldn't risk it. And If you would max 104 blck
Most ES won't have been stressed to the max. The majority of ES parts are used for functional and compatibility testing. Very few ES samples are used outside of say Intel for things like thermal stress testing or accelerated aging testing.

As far as materials, they should be exactly the same as production parts unless there was a defect discovered in the manufacturing or assembly process which is extremely rare. The dies themselves are run on exactly the same process and the substrates and associated parts are exactly the same as for release as they are just early parts. It would make little to no sense to use different materials since the whole point of ES is to test for volume production at external customers (OEMs). Yes there are internal ES part at Intel, but those generally don't even have labels and rarely make it outside of projects.

I was looking at this:

Now we can see M0 and a Stepping of 2 and CPU-Z reads them as ES. These should be QEYP but the above links they are being sold as Retail/OEM such as the eBay link you provided from China. So from what I understand is that there are two ES samplings (1 and 2 stepping) with 2 stepping being retail/oem?

Also what are the chances that an ES would be remarked and then sold off as OEM/Retail?
Nooooooo

Those are 2 different chips.... QEYP is a 12c ... Early stepping... I wouldn't use before QF on the MCC die (R2)
2683 v3 is a 14c die, and you want QG steppings of those...
Intel Xeon E5-2683 v3 - CM8064401609728

I would have to do some digging... but as far as I know... QG is C0/C1 QF is B0 for 14c+ chips on v3 ...
M0 shouldnt even be... for HCC/14c chips.

Also note that QF is not C0... it is B0 ... the hwinfo says QF/QG and it really can only be one... it just doesn't know the difference evidently. I wouldn't buy rebranded chips like this... not at that price.

Thank you!
What do you think about that one:
Intel Xeon E5 2673 V3 QS 2.4Ghz 30MB L3 12Core 3.1Ghz 105W LGA2011 Haswell-E/EP

Most ES v3 came out of OEM servers during update to broadwell-EP v4 cpu.
They ran 2 years, so no one can expect how long they will live.
Haswell-EP processors are build for stable reliable servers.
IMHO: if u take a NEW motherboard, with good cooling new capacitors of course, these ES will live long.
The ES v3 currently on the market are not stressed intel lab samples, the X99/C612 platform exists since more than 2 years.
Because Intel can't inhibit sell/reselling of ES, they are lower performance to not compete than OEM/retail.

Can you tell me what QH is?

Sorry for noob question which might be considered off topic...:)

Can I use 2400MHz memory with a E5 v3 chip on a Supermicro board X10SRI-F?

I would guess this is all right and the memory would just downclock to 2133MHz using a v3 chip.

I am still looking for my ES chip, so it would be good if I could just get 2400MHz memory that would suit both v3 and v4.

TIA

QHxx is what i see only used by v4 broadwell-ep ES.
example of E5-2650V4 ES (12 core)
ES0 = QH2N = A0
ES2 = QHV6 = L0
QS = QKxx = M0
QKxx will be QS !!!

steppings for v4 OEM/retail
LCC = 4..10core = R0
MCC = 12..14core = M0
HCC = 16..22core = B0

Yes, that works fine

Offtopic - CPU-Z new version with realtime clock window
CPU-Zclock.gif
A right mouseclick inside the cpu form opens core clock data too.

Thanks for your reply.
Got 2 E5 2998 V4 QHUZ on the way and was curious.
Hope they perform good :p

yeah it's fine but some chips supports up to 1866mhz so if u used 2400mhz or 2133 mhz u won't used them all , u will use 1866mhz only

I noticed that you are using Bios F22 with that Gigabyte X99 motherboard. Have you had any issues with that ES even with previous bios versions? I am looking to get the E5-2683 V3 with a Gigabyte X99 motherboard but wasn't sure whether to spend more for an OEM/Retail one or get a B0 stepping ES.
I had no issues. for haswell-ep v3 cpu you don't need bios F22.
If you don't have a motherboard i don't recomment gigabyte, theys have no compatibility with v4 ES,
and only a M2 pcie2.0 x 2 (10Gbit). With OEM/retail or v4 QS its no problem.
Try any ASRock x99 mobo.

All i found about it is bad news.
It seems that this cpu only works in pairs(custom one for OEM server manufacturer)
needs a second cpu present.
what will run is:
E5-2695v3 2.3ghz QFQG(pre-QS),QG7R/QGN4(QS)
E5-2695v3 2.2ghz QEY6(ES2)


".......These are engineering samples and work in pairs. Item was tested on my Asus Z10PE-D8 WS mobo. "
Can you clarify if the QFQG and QG7R/QGN4 are able to run on a single socket mobo?

that are totaly different ones,they work-
the one i talked about was a QDxx...but that was just a theory why it not works...

Hey guys, ive read this entire thread (Patriot and RolloZ170 your posts are extremely informative!) But im not really sure what to buy, im caught between:

1. getting a QF/QG haswell since these are close to the retail release of that chip right?

or

2. getting a QH broadwell with more cores and a newer arch, but its not that close to the retail release. The QH's all seem to have stepping A0 or A1.

How big of a deal are future mobo compatibility issues with early steppings? It seems Asus and Gigabyte X99 mobos dont support early stepping chips at all but Asrock dont seem to care: Intel Xeon E5-2683 v4 Broadwell-EP CPU 1.6GHz 16-Core 120W Max 3.0GHz QH27 ES

Will Asrock start to care and lock out early stepping chips? Has that ever happened before?

tl;dr
Should I buy a close to retail older haswell or futher from retail newer broadwell?
Also how big of a problem is mobo compatibility for early stepping chips?
