truly impressive expertise!
my main goal is using SPR-SP ES CPU to test 300 series optane dcpmm with different SKU. since i have succeeded with C741 chipset and Q079, i am wondering the possibility to power (or even overclocking) them with W790 chipset, so i am looking for some suitable W790 motherboards. I’m short on funds, so I have to be thrifty.
anyway, thanks for all the info.
Does any c741 motherboard support DCPMM 300?

I have got q077 and qyfs with motherboard ms03 ce0. But I found out that the cpu cannot boost over maximum frequency of all cores (2.7 GHz for q077) even at light load, which should be easily over 3 GHz. So I wonder what’s the problem?

The system installed is windows server 2022. And I have set the power policy to BestPerformance in BIOS and windows. Still not working. The only way that works is to adjust the count of cpu cores to 16 in BIOS by setting the disable mask

if you tweak the system to multithreaded performance you wonder you loose single threaded ?
max single core boost works only if many cores have NO LOAD(idle 800mhz), with windows high.perf. that realy rare happen.

ES = mostly lower clocked.
QS = same clocks than prod.unit.
QX97 is afaik stepping C0 = not work on latest BIOS.
edit: Gigabyte MU72-SU0 runs it.
Qx97 is cpuid 606A6 stepping Dx
(thx to MillionMiles)
So as a D0, could it work with Supermicro X12SPA-TF on some/all BIOS?

Any ideas on getting a pair of Q2P1 (8952+ ES) working on a Gigabyte MS73-HB1?

I know it's not the latest ES but it's all I could get on eBay currently.

Tried the bios that the mobo came with and the latest, can get into IPMI to update that and BMC.

Mobo power lights come on, can access IPMI, but if I try to boot, the power cuts off within about 1 second and doesn't work again unless I unplug the ATX cable and re-plug. Tried a second PSU already that's known working which was my first guess, now I think it's the CPU microcode.

I was under the impression Gigabytes work for ES CPU's but guess not in this configuration.

It's model family F model F stepping 1.

Thank you for your time!

no, the microcode is there.
you have other issue, bad CPU, bad CPU installation.
system should turn on, maybe no display but it sounds you have a short circuit or overload.
have you any pictures ? maybe we can see some missing cables e.g.
i have seen Q2P1 only at ebay, not on goofish nor taobao, no further info, which is weird/strange.

It's saying my photos are too large to upload.

All cables are connected though, 2x CPU, 2x PCIe, 1x ATX.

Current specs:
4x 64Gb ECC DDR5 (in correct slots according to manual)
2x 8952+ ES CPU's
MS73-HB0 motherboard
2x Gen4 WD_Black 8tb NVMes
GeForce RTX3050 LP GPU
MSI AI1300P PSU

About to re-seat the CPUs as all cables are fully clicked in and will report back or find a way to lower the camera resolution to upload.

no PSU ?

you need at least a 750W modern PSU.

To users with EMR-A0:
We tested Q30G and Q2SR on ms33 and ms73
These cpus are able to run with R10 and R11 bios, without bios modification, ONLY TESTED IN ONE SOCKET,
Also, directly use these bios will cause really low performance of these processors...And a long POST time more than 10mins

I noticed it as well. It took 5mins to boot up with q2t7 on ms03 ce0 with R11 versioned BIOS. But it eventually failed at upi link initialization (not sure)
