ES Xeon Discussion

[Civiloid]

Thanks for the information I will use it in the future

I had a Chinese Coolerserver M97 as a temporary cooler, which looks like a U12S clone. I can also tell that while it looks similar, it is worse. Fans need to spin up faster on that, and temperatures are about +10C compared to Noctua. So unless you get it for less than 50$ per cooler, I'd probably recommend paying more for Noctua but just having a better experience. It was also similar size-wise, but clips are way more complicated to install than Noctua (it would be no difference in that regard on a single CPU motherboard though).

In case that would be of interest to anyone, I've installed dual Noctua NH-U12S DX4677 on my Gigabyte MS73-HB1. Although it is officially incompatible, it actually works well. It is a bit hard to snap in the fan, but other than that, it is okay. I basically pushed the clip between radiators with my fingers from the side, which is suboptimal, but ok.

My 8490H ES E0 is barely audiable at its current state and stays relatively cool with 65C (149F) on CPU under my workload and y-cruncher.

Spoiler: How that looks (so far without a chassis)

What are these cards for? Never seen them before.

I am using Freezer 4U-M | Multicompatible 4U Single Tower CPU Cooler | ARCTIC. Marketing says it is "compact" but it is huge but amazingly quiet. I don't hear any fan noise, even outside of the case. I chose that one because it was the cheapest but I am very pleased for a single socket solution. I don't think it will fit a dual socket MB.

From left to right: Mellanox ConnectX-5 x2, Mellanox ConnectX-6 x1, Mellanox ConnectX-5, Mellanox BlueField-2 (ConnectX-6 DPU), Mellanox ConnectX-5 - bunch of network cards as I'm using that thing as a dev machine to test network cards performance, patching some opensource projects around that and slowly drafting my own packet generator.

I don't think it will fit a dual socket MB.

Yeah, doesn't look like that, because of the fan orientation.

Are there any motherboards that could possibly work with a QXHU 112L sapphire rapids C1 stepping 4677 eng sample? I tried a x13-swa and a w790 sage se, no luck. Someone mentioned ~30 pages ago that dell or Lenovo boards might support as far back as A0? (Which would be cool, somewhere I have some A0s too).

in any case you need pre production BIOS which comes usualy not with the board/server.
if you get them to work youhave to live with many issues, BIOS full of bugs.
i have some C steppings too, but D0s are cheap and E steppings come, makes no sense trying older steppings to work.

Makes sense!
Bugs are fine, this is just for fun if it even was possible.
And yes D0 and E steppings are cheap unless they are workstation skus! Or I am missing some only aliexpress listed qs samples or something haha.

if your C steppings CPU even not gives a "cd" code it's dead.

the most beautiful women are always the most expensive. the more people want it, the more expensive it becomes.
there are at least three D0 SPR-WS models, but i haven't seen for sale.

beautiful women, most frivolous
in our case, in this thread we need to choose what seems to me the golden mean

I was watching for cheaper SPR-WS ES/QS for last few months and so far I haven't seen anything other than QS (E3) and for almost MSRP...

Yeah same, there are some okay deals for 3465x’s for 1800-1900 I guess, given the msrp is ~3k, but otherwise yeah only a few 100 off it seems.

Hmm interestingly, that is what my qyfq does on my x13swa, but worked fine on my w790 as expected.

W790 supports D0, x13swa not with BIOS 1.0a and up.
but x13swa uses not a RoT Firmware.

Yeah I know/knew that, I did it by accident once. (my cpus have an adhesive graphene sheet on them and I didn’t label them…they are now though!). Just saying it was 00 on my supermicro board - is that what you mean by not a RoT firmware? What is RoT firmware? Root of Trust firnware? So they are not encrypted?

 

[RolloZ170]

none SM BIOS is encrypted but digitaly signed. on RoT system the BIOS is validated before update process and before start of CPU.
X13SRA,X13SWA are not RoT protected(so far).
i can bot update BIOS with X13SRA BMC/IPMI (only BMC FW)

 

[AVID-MEDIA]

What is RoT firmware?

Helpful Info

 

[MillionMiles]

X13SRA,X13SWA are not RoT protected(so far).

that mean the modified BIOS can be flash in and work?
like this:

i tried this already. modded BIOS works fine but not with D0 CPU.
Intel ME blocks 806F3 from working. on ASUS W790 i got at least "cd" with 806F2 CPU, on the X13SRA it stays at "00"
D0 needs ME 16.10.0.1400 or earlier. must be flashed with sop8 clamp and programmer(have done this with ch341a)
PM me is you need BIOS with D0 support.

There are about 2-3 sellers who sell them on ebay:
One you've mentioned, and as well those people:
1. Intel Xeon Platinum 8490H ES S4 1.6-.5ghz 60C/120T server cpu support ms73 hb1 | eBay
2. Intel Xeon Platinum 8490H ES Q03J 60C 120T 1.9GHz LGA4189 112.5MB 350W 4800MT | eBay

Probably more, but you basically need to inspect all the offers.

Just remember - you can try negotiating with them and maybe lower the price by 30-40$ if you buy more than one things for them. The more you buy the better discount

Just to confirm, these devices run at the same full clock rate as the production parts?

I wanted to buy from this seller, but I was alarmed by the incorrect information in the description. So I decided to wait a little
