ES Xeon Discussion

[RolloZ170]

Can the official version of W790 also use QYFS or QYFR?

what do you mean with official version ?
ASUS W790 SAGE & Ace work, ASRock WS W790 work,
supermicro W790 not (X13SRA only with BIOS mod)
Dell 5860 not...

but I've only heard that it can be lit up with ES motherboard.

QYFS or QYFR works in any gibabyte C741 motherboard with latest BIOS.
edit: this is not the usual case/the norm of course.

I also have a question: Does the ASUS W790 motherboard have a BIOS lock? I saw on other blogs that they used the ASUS W790 ES motherboard version 1.01 and were able to power on the ES 8480 and overclock. Can the retail version of the ASUS W790 do the same?

Does anyone here have more details about this Q0TU QDF (Qualification Design Sample), a 4th Gen Xeon LGA4677 CPU?

It seems to be an overclockable Xeon Scalable processor (not the W9-3495X), because it supports Optane Persistent Memory.

Qxxx is called QDF, prod.unit Retail SRxxx is called S-SPEC
QDF does not hint to any stage of ES, can be ES0 or QS.
this stepping E2 has still no Brand string ("0000" instead) - we can't guess about a target SKU at that stage.
it is not unusual that ES have more feature enabled than later prod.units.
If it runs on a W790 motherboard the bad news is no W790 BIOS supports PMEM (why it should)
and no C741 motherboard support overclocking ( you have to mod. BIOS and try XTU )
stepping E2 of Xeon W9-3495X is Q19N

where did you got that from ?

Got It From My Friend
It was a crazy module which can run in all-core 3.9G with 56cores!

Optane PMEM 300 kills everyone!

sorry, i don't see that. max. package is 378Watts and normal for a 56 core but 56 cores @3900mhz will need over 500Watts.

Absolutely working
Need 550w +

it is indeed a special one, talks DMI3 and DMI4 like SPR-SP D0s, runs on W790 and C741 motherboards.

 

[Ti_EgrDiv]

I am interested that why SPR has 12 steps. Are D0 steps ES (like QYFS) have some major bug?or just the Cost or Yield problem

If I remember correctly, they change the memory controller, therefore that step4 and above 4th gen xeon support PMem 300 at C741. However, D0 support PMem 300 indeed, but must be in es C741 chipset.

 

[Ti_EgrDiv]

The most interesting part is that in the latest R12 BIOS (the latest BIOS I have tested), Gigabyte (MS03-Ce0) did not remove the support for PMEM in the BIOS， which means that users can still use the fourth generation along with PMEM .

Indeed ; )
But only AD mode left in the BIOS configuration(s). I haven't try to use ipmctl to configure memory mode in the OS.

Does anyone here know if a QYFS works in a 06CX9 motherboard from the Dell Precision 7960? I bought a QYFS for cheap and the 06CX9 looks pretty promising for its price but it officially does not support the QYFS

 

[RolloZ170]

yes i know. does not work.
there is no way to modify BIOS because Intel BIOS guard is running.

 

[Nima0908]

Thanks for your answer. Thats really sad . Then i need to look out for another board. I dont really feel like paying more than 500€ for a board but that'll be hella difficult.

the Dell Precision 7960 06CX9 motherboard needs custom case, custom Power supply, custom FANs,
custom Front Panel (the Embed Controller is on it like at 7820/7920s)

 

[Nima0908]

I already have all of this figured out, thats not the issue. I would have put it in a old server chassis that i have laying around. It would need some modifying but that aint the issue. Sad that there is no way to get it working

 

[Nima0908]

What about the M41247-601 from HP? It seems to have a way bigger range of usable cpus, so would this maybe work?

not tried.
but HPs BIOS also can't be modded, but this is required on actual BIOS to make SPR-SP D0 work(except ASUS/ASRock)
you need then in any case a early or Test/Debug BIOS.

 

[Nima0908]

Aight. So ASUS/ASRock and Supermicro are my best options?

If you wish to try the ES/QS CPU, then a Gigabyte motherboard is your best choice.

W790
ES = ASUS/ASRock
avoid supermicro / Dell / HP / Lenovo of you want to run ES.
QS work on ALL motherboards who support the Retail version.
QS = prod.unit just with ES bit set.
if you see "0000" in BIOS or CPU-Z it is NOT a QS.
