Ok, a last check: QYFP can get past BIOS without adjusting C-states, but no other QY**s can, right? Or does that only apply to Asus W790? I see people in this thread using QYFU with Asrock, but unless I missed something they haven't mentioned the C-state adjustment requirement. Also, my board may only be able to use 6/8 RAM slots due to pin damage - I'll adjust it again when I put in the new CPU, but if it doesn't fix will having only 6 16GB RDIMM cause any trouble?

350W, more boost clocks.
QYFS TDP=350W boost 3700
QYFU TDP=300W boost 3500
QYFQ,QYFP TDP=270W boost 3300
What about QY08?
This one has 350W TDP and 4.0GHz boost clock so it seems good in this standard, but some seller says this is 48 cores and others say this is 56 cores with screenshsots, not sure which is correct.
Also the seller screenshot says VT-x is not supported on this, but it might be because the seller was running cpu-z or hwinfo in the virtual machine.

QYFV is also attarcting my eyes, this one has 350W TDP and 3.8GHz boost clock with 52 coress.
There is also QYG6 with 350W TDP, 2.5 GHz base clock with 48 cores but this one severely lacks information.

disabled in BIOS by default.

they show random pictures, i guess 56C is from QYK8. as long as you get QY08 it is 48C.

QYFV: my info is 48C

D0, ES from 8469C OEM.

Q071 arrived with no POST. Guessing DOA.
Said Q071 works in an MS33-CPA and that pair now acts as a server.
Another confirmation that the MCC R0 doesn't work on Asrock W790. When recorded, it stepped to B7 (iirc), then EF before instantly reset-looping.

I also discovered PCIe/BCLK scaling with GPU changes, suggesting no isolated BCLK generator. Not very fun, unlike my usual 4.62GHz Westmere Xeon.
As a result, I no longer have the W790 boards and will move to the ES Xeon general if I have anything more to say.

I got QYFS for my Asrock W790, but it had no POST with code 00 in the exact same setup that booted for my W3 Xeon. The CPU is assumed DOA, but is there anything that I may be missing in my tests of it?

QYFU work fine with Asrock W790 WS 7.01 bios.
Could it be that my BIOS is too old for the ES CPU somehow? I've got the 3.01 BIOS. Alternatively it could be QYFS does not work with the board, but QYFU does.
This is all assuming that the CPU is not actually dead...

Can QYG6 works well in W790-ACE? I cannot find any detailed information yet.
QYG6 is 8469C ES2 D0 48C 2.50Ghz
'C' confidential SKU for select customers. you never know what is different.
just buy and test ( like i would do for fun )
why don't you go with QYFS on the safe side ?

QYFS has too many cores, but limited power. I want a not too bad single core to run my code, so maybe QYG6 is the best choice for me. With 48 cores parallel in Matlab, the frequency of QYG6 is 3.1*1.1 G. Really good for me

Barev, Interesting CPU. Yes please share the HWinfo report or screenshot.
Also if you need higher clocks and fewer threads on matlab you can probably get Max speed turbo if you disable half the cores.

Does anyone have the toturial for the overlock of the ES cpu in W790? I can just let the QYG6 at 108 bus speed with 2.35, 1.8V in. Larger than 108, I can not enter the Ubuntu 22.04 system.

BCLK change PCIe USB / Sata clock too. depends on your GPU how high you can go.
108mhz is very high, rare reached by others.
SPR-SP have a fused per core power limit, much above 4Ghz is not possible or result in crashes.
i could OC my QYFQ from 3.3Ghz (default) to 3,9Ghz. but if you already have 4ghz boost or 3,7ghz there is not much room.
be happy to have a cheap CPU on that platform.

I want to know how you change the multiplier of your CPU? Directly change and fix it in W790 BIOS? I do not have any information to turbo my CPU.

Just a thought.
I have the Asrock W790 WS motherboard, I use it with a E7-2475X CPU, but allow me to make a suggestion.
It would probably be helpful to those in this thread to always state which bios version is being used, as I have noticed a slight, but quite measurable increase in performance depending on the bios with the E7-2475X, so I would venture there would be like results for other CPUs and perhaps even enhanced compatibility. Currently the 9.01 bios gives me the best the performance, YMMV.
