Wow, I'm shockingly well equipped to help. I run an HPC business in Ontario and was looking to start swapping out our ROME systems for EPYC 9000. I have 2x64 and 2x32 core variants and can kit them out as you described. YGPM

Well I have a pair of "Genoa 96 core monsters" and was coming here to check if this worked on them. No reports yet?

yeah, S8253 it doesn't boot noticibly faster, but the screen is on telling you what it is doing with a few seconds, whereas first boot with SMC H12 board takes many minutes to post a picture to screen.

Gotta love that 5 minutes of hoping it works when I click the power for the first time on an EPYC 7000 system. BTW, The tyan board posts in like 5 seconds instead of 5 minutes. it still takes forever to initialize on first post, but at least the display lights up and tells you what it is doing...

That is also correct by my understanding. The pcie 5 signal distance is rather poor and requires repeaters everywhere etc to work on pcie slots, so the difference between lm0 and lm1 is probably this peripheral infrastructure (the repeaters) and there is no impact on the cpu interconnect.

My personal SP3 systems are mostly watercooled, and I would certainly do the same with SP5, but I also need air cooled workstation-like solutions.

P.S. I would love to know any cooler options that might be quieter than Dynatron J12 3U. Something like Supermicro 4U or Noctua or something that could make for reasonable workstation usage with 280W (or more) processors...

Similar story on buying in north America. MZ73-LM1 is much cheaper but months away for lead time. I would rather it as I don't need PCIe 5, but I ordered some LM0 to get started with.

What awesome luck. I just got 4x 826 that I need rails for. YGPM

These work FYI: M393AAG40M32-CAE 128GB RDIMM 3200 4Rx4 (3DS 2H 8G x 4) x 36 Both supermicro and gigabyte boards. Not relevant to "cheap ram discussion", but just in terms of broad compatibility and ranks.

Also EATX is ambiguous. do you want full 12x13? SSI-EEB SSI-CEB

I don't know about smallest, but I'll throw this in for your consideration as a compact and well ventilated choice. https://www.amazon.com/Silverstone-RM42-502-rackmount-Compatibility-RM42-502-x/dp/B09227RQV2

yeah basically VRM is the limit on H11DSI & H12DSI.

oh I should try that. I always fired up edge and figured it was a firefox / chrome issue? yeah all ast2600 boards from supermicro do this for me.
