there are < 32 core XCC models.Is XCC(>32 cores), means higher idle power and core to core latency.

little Notes:This thread is amazing but very hard to find the basic information. How about an spreadsheet to track the knowledge.

i have tested Xeon W3-2423 and Xeon W5-3425 on X13SEI / Gigabyte MS33-AR0XEON-W work on X13SEI/X13DEI?
we never got any proof.I have seen a discussion of this on STH somewhere , and some one said X13DEI with BIOS1.1 can run XEON-W
Thanks for the information I will use it in the futureIn case that would be of interest to anyone, I've installed dual Noctua NH-U12S DX4677
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).Thanks for the information I will use it in the future
What are these cards for? Never seen them before.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.
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.What are these cards for? Never seen them before.
Yeah, doesn't look like that, because of the fan orientation.I don't think it will fit a dual socket MB.
in any case you need pre production BIOS which comes usualy not with the board/server.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).
Makes sense!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, makesno sense trying older steppings to work.
if your C steppings CPU even not gives a "cd" code it's dead.Bugs are fine, this is just for fun if it even was possible.
the most beautiful women are always the most expensive. the more people want it, the more expensive it becomes.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.
beautiful women, most frivolousthe 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.
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...Or I am missing some only aliexpress listed qs samples or something
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.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...
Hmm interestingly, that is what my qyfq does on my x13swa, but worked fine on my w790 as expected.if your C steppings CPU even not gives a "cd" code it's dead.
W790 supports D0, x13swa not with BIOS 1.0a and up.Hmm interestingly, that is what my qyfq does on my x13swa, but worked fine on my w790 as expected.
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?W790 supports D0, x13swa not with BIOS 1.0a and up.
but x13swa uses not a RoT Firmware.
