    You say it supports "8x DIMMs at DDR4-3200 speeds or 16x at DDR4-2933"
    Is that a limit of the motherboard, or is it a limit of the CPU? I mean do all EYPC systems have the same limitation?

    What's the intended use case for slot 7 "PCIe ESM" and the slimSAS 4i connectors labeled slink0-3?

    Those Storage Review guys didn't catch that the PCIe slots were not functional. I guess they didn't actually test the server.

    @StevenDTX It's $2250-2275 a bunch of places online. There's even a Google shopping card with the prices from multiple shops and the ThinkMate guys have it on their site already with a configurator Gigabyte 2U Server R272-Z32

    It's curious ThinkMate doesn't have the P CPUs listed but they've got the normal ones only. The STH review used almost all P's and it's a single socket so I'd think it'd work.

    All EPYC 7002 CPUs will downclock at 2DPC. You will also see DDR4-2933 at 1DPC on most of the older Gen1 platforms.

    @ari2asem the EPYC 7001 chips are missing features like PCIe Gen4. We did not get to test this platform with older chips just to get it out in a timely manner. Here is the spec sheet which may help R272-Z32 (rev. 100) | Rack Server - GIGABYTE Global

    On the other hand, I would expect almost all buyers of the system to use EPYC 7002 chips in it.

    Is the broken forward compatability from 7001 to 7002 parts indicative of a potential small fire sale of 7001 only platforms? Seems like a great homelab niche if the logistics can be managed.

    Ah yeah, I see now that all servers do the same thing. Cascade lake down clocks to 2666MHz with 2DPC.

    On another note, I was thinking EPYC Rome is meant to have a single PCIe root, that would theoretically mean that DMA and RDMA work a lot better than Cascade lake (which doesn't have single root)

    We've been evaluating the various 2U 1P EPYC solutions for use as next generation all flash ZFS storage servers and run into some problems.

    Tyan TN70A-B8026 - works with Open Indiana latest - OmniOS CE Stable and Bloody spontaneously reboot without a crash dump during install
    SM AS-2113S-WN24RT - all the illumos based distros including OI I tried spontaneously reboot without a crash dump during install although everything works fine with Linux/Windows

    If you still have this box, any chance I could get you to try Open Indiana or OmniOSCE on it and report back? Out of the three, I like this Gigabyte on paper the best if it would work although I have to say despite being the first offering and now feeling a bit dated, the Tyan isn't bad and it seems solid at least with Open Indiana. Looks like the Gigabyte may even be cheaper than the Tyan, if Google pricing is to be believed.
