ES Xeon Discussion

[RolloZ170]

if the leak was true, Intel may have been planning support for DCPMM on WS for quite some time at least

no,all final stepping QS.
Intel® Optane™ Persistent Memory Supported - No

if you believe some chinese sellers, all SPR-SP also have 4x16GB HBM built in.

and since SPR-SP D0 has proved to contain it, this maybe worth a try?

You may have missed the fact that Intel no longer supports DCPMM 300, this includes intel MRC packages for BIOS support.
besides there were steppings after D0 because they have bugs.

indeed, i think you're right. maybe I should shift my attention to lga7529.
thanks again for all your help.

i don't think pmem 300 is supported there.
or LGA4710 ? maybe cheaper boards.

thanks again for all your help.

checked some old conv's
one of my contacts tried pmem 300 on ASUS SAGE with D0 ES, pmem not detected(i checked BIOS for options but found none)
also very hard to get MM on gigabyte boards.

 

[RolloZ170]

my friend successfully powered four of his pmem 300(SKU: NMC2XAD512GQS) with Gigabyte MS03-CE0 and Q079, others have bad firmware version and can't go through self-check.

powering and get to memory mode are two diff. things. and if you have luck, never update your BIOS.

yes, i know. he tried both two modes and told me the restrictions on the capacity ratio between DRAM and DCPMM in this generation(Ruby Pass) are stricter in MM mode than the last one, and it cannot be lower than 1/8. AD mode, as usual, is of no limit.

and if you have luck, never update your BIOS.

that's true

but dual SPR ES D0 doesn't scale good in CBR23 for some reason, CBR24 looks better.

that nice, thanks for pointing me out. I have considered CBR23 as baseline for my task. My real usage involving all cores utilization, no limits, full load.

Q079 is locked, so you can OC only by BCLK. this works only with ASRock W790 WS R1.0(Hyper BCLK Engine)
on all other boards your PCIe etc clocks are rising with the BCLK and get unfunctional at some point.
for the HP/Dell W790 boards it is highly possible the intel ME don't start the D0/E0 ES like the SM X13SRA-TF.
remember my X13SRA-TF starts ES only with early/old ME 16.10.0.1400, next ME ver. 16.10.5.1562 blocks ES from start.
there is a way out, you can update early/old ME but keeping the ES friendly config.

Dell 7960 BIOS 1.0.5( 25 Apr. 2023 ) missing D0 microcode but E0 supported.
HP Z4 G5 WS BIOS 01.01.27 Rev.A ( Nov 16, 2023 ) removed whole D0 support, E0 supported.

how update early/old ME but keeping the ES friendly config.? if buy this mb, how can i confirmation its ME version is 16.10.0.1400?

replace only the code not the data.
some vendors like ASUS provide ME update package , its based on FWUpdate(Intel CSME Sytem Tools)
but i made it by hand with HxD.

if buy this mb, how can i confirmation its ME version is 16.10.0.1400?

If you buy a new x13sra you will NOT get a ES friendly ME.
the x13sra i bought was a board for evaluation, the seller couldn't update to latest BIOS because of ROM layout mismatch,
i sayd "no problem, i take it as it is...."

@RolloZ170 Gonna buy the ms33-cpa motherboard, would the q03j cpu work? Any quirks I should know about? Also I assume the motherboard is some sort of testing sample as well?

 

[RolloZ170]

yes, stepping E0 (early and late) work, the BIOS is similar to MS33-AR0 e.g.
i have Q08S E0 running on it.

Also I assume the motherboard is some sort of testing sample as well?

no: MS33-CPA-V10 is OEM, not retail consumer market.
any BMC FW lists it in the etc/devmaps folder

Awesome. How is the performance (I saw you had a similar setup)?

normal, it is no different.

8461v prod unit srm7d only neeed 1800 renminbi(yuan) in xianyu app? why so cheap since it is not es/qs cpu?

8461v is UP only. used and seller needs money, or fraud(ES/QS, not prod.unit)

 

[roidinev]

So must check and confirmation.

Just found the perfect SPR-SP ES for heavy load. The code is Q28U and it reports as Xeon Gold 6459C. The stepping is S3. I haven't found no information on it so i think it is a OEM SKU but i have no idea which brand it is OEM to - i got it from a friend in "exchange" bundle. For some reason HWinfo64 detects it as Gold 6455B (no idea why). This processor cooks with fire - it goes to 3.9 all core under full CPU-Z stress load (3.8 all core under continuous Cinebench R23 load) and stays there pulling 370W from the socket. Tested on Supermicro and Tyan server motherboards with the latest BIOS - works perfectly fine. All i wish now is i can find it in the D0 stepping to put into my Asus WS until Xeon W7-34xx ES/QS/Prod will come down because W7/W9-35xx hit market and these will be replaced. This Gold is... well - pure gold

'C' confidential SKU for select customers.
HWinfo: CPU Brand name is out of the processor(cpuid) - HWinfo table is wrong, you ca report that to Martin if you like.

It reminds me of some Q071 CPUs I found on the same app with a 270rmb price tag

i payd 450 but had to get it to europe for same money.
