Can anyone confirm?
correct. for supermicro there is only the X12DPi that support ES1 with BIOS 1.x. AFAIK all other X12 supports ES1 with BIOS 1.0, downgrade is not possible over IPMI so you have to replace the BIOS chip.

> rrubberr said: Any idea if they’re supported on boards like the SuperMicro X12SPZ-SPLN6F?
generaly all supermicro UP boards do not run ES with B0/C0 (step 4,5) stepping.
the only known SM board with ES(step 4,5) support is X12DPi-N(T)6
stepping D0 (step 6) runs fine on all boards with latest BIOS so far.
ASRock SC621 and Gigabyte MU72/MD72 do support ES.

there are ES1 and ES2 3rd gen. avoid ES1.
for ES1 QU9B/QU99/QV2? i.e. you need X12DPi-N6 BIOS lower than 1.2 to work or on UP motherboards unofficial BIOS 1.0.
ES2 step 6 work on all SM boards, i have QWAQ 6330 ES2 working on X12SPL/X12SPM.
your X12SPM (i have one too) runs only ES2 stepping D0 (step 6)
if you can get BIOS 1.0
downgrade to BIOS 1.0 is blocked, the BIOS flash chip must replaced with a preprogrammed one containing BIOS 1.0
>cheekycheeks said:Hi,I recently got my hands on a supermicro X12DPL-i6 essentially for free. Could someone help me in finding an Xeon ES that would work with it. Ideally above 12 cores. Or am I out of luck with this motherboard?
look for stepping D0 like
QWAS=6346 ES2 16 core
QWAQ=6330 ES2 28 core
QWAT=8368 ES2 38 Core
QUxx & QVxx are B0/C0 and do not work on bios above 1.00
check if you can swap this board with X12DPi-N6, this supports B0/C0 ES1/ES2 with BIOS up to 1.1b (not with 1.2 and up)
unfortunaly 1.0 is unofficial BIOS, and can not be flashed by normal way (IPMI / SUM)
we have to swap the BIOS chip. i replaced the chip with SMT socket.

you need asrock or gigabyte motherboard, or supermicro but:

606A5 - Ice Lake-SP C0
606A6 - Ice Lake-SP M0/M1 D0/D1/D2
most sellers mean ES2 = QS.
HWinfo searched in a database for mathing parameter, if one or more is found it will be displayed. Note the Brand Name is not compared.
So it can be happen QS is displayed but Brand Name is still "Genuine Intel(R) CPU 0000%@" (Brand Name is what CPU-z shows i.e.)
>Spartus said: If I went with QS, would I expect near "final" speeds and compatibility, but just have a strange name? I'd be able to update bios though and have more board selection?
my first Ice Lake was a QU9B Gold 5315y ES1 - runs on Gigabyte/ASRock boards out of the Box.
on Supermicro X12SPL need BIOS 1.0 (Note: downgrade is rejected,replace BIOS chip)
next is QWAQ 6330 ES2 D0, mentioned as QS by the seller, but only 1.80Ghz base. works on X12SPL latest BIOS.

you should go with QWLQ
i have seen aQWLQ as production unit. anything can happen because this 837xC are Confidential OEM SKUs.
QVLS,QVLP(330W) are 606A5 - Ice Lake-SP C0.
>Spartus said: They all list 3.5/3.6 GHz turbo
looks like the 8375C clocks all cores 3500/3600Mhz (non AVX) results in 300/330Watts.
only some Custom OEM go all core 3500/3600Mhz but not the Intel standard SKUs(ie.8380 turbo 3400,all core 3000)
> Spartus: If I cared about non-avx I'd be buying more AMD, but I have some need of an AVX-512 monster. Any insight on how avx clocks may vary between qwlq and final? What board should I get for it you think? X12DAI, X12DPI or, or MD72-HB_ would be my go to. You said support can disappear in a future BIOS, but mostly due to TDP reasons?
i had a ASRock Rack SPC621D8-(2L/2T), they support officialy 300W TDP.
Supermicro is working today, but officialy 270W TDP can be dropped in next BIOS builds like it happened on X11SPM.
Note the X12DPi lacks heatsink for CPU0, better choose the X12DAi Workstation one.
Gigabyte MU72/MD72 is OK too but specified to 270W TDP like supermicro's.
>Spartus said: Any insight on how avx clocks may vary between qwlq and final?
we can only guess. But the 8375C is apart from rules, its a custom OEM SKU.
>how did you configure the BIOS to run 3.6G when idle or on a single core? My qvm7 + X12 Dpi N6 only run 3.0 on single core. Even when idling, no core is running higher than 3.0Ghz.
no changes other than this:
disable 18 cores.(bitmap FFFFF)
windows power plan balanced, run CPU-Z stress cpu to put load.
edit/update:
i use X12SPM with BIOS 1.0, you can not expect the same BIOS default settings.

if you run linux maybe you have to set to "BIOS Controls EPB" and "Maximum Performance"

oes anyone know the difference between these two CPUs? Both are listed as Xeon W-3345 QS. Both show the same S-spec (SRKSU). There’s are 20 core and 24 core models listed. Officially, the 3345 is 24 core. I can’t find mention of a 20 core version anywhere, but on some of the 20 core listings they show screenshots of it running with 20 cores.
I’m planning on putting one in an X12SPA. QS there should be no issues, correct?
20 Core: Intel Xeon W-3345 QS Version 20C 3.0GHz 250W LGA4189 DDR4 3200 CPU Processor | eBay
24 Core: Intel Xeon W-3345 QS 3.0GHz 24C/48T LGA4189 36mb 250W CPU Workstation | eBay
...
So the seller is saying that the 20c version is “QS1” and won’t work in supermicro boards. The 24c is “QS2” and is almost the same as retail and will work.
That seems to go against the pictures with the 20c version CPUz not showing it being an ES chip, but the 24c does show ES.
20c is QK7K (no listing on CPU world)
24c is QXZJ (

i highly doubt that.
QX7K is WS [ICE LAKE] Processor 3.20 GHz, 30M Cache, 20 Cores.
It's on M0 stepping, this processor wasn't included is the final production configuration.
20c QX7K cpuid 606A6 - Ice Lake-SP M0/M1 D0/D1/D2 (LGA4189)
24c QXZJ cpuid 606A6 - Ice Lake-SP M0/M1 D0/D1/D2 (LGA4189)
it is a fact: BIOS 1.0 supports ES B0/C0, all later BIOS not.
only the X12DPi supports ES B0/C0 up to BIOS 1.1c
