"support for up to 128 GB of non-ECC DDR4-3200 memory"
So completely pointless for its target market.
"The memory slots allow for up to 128 GB of ECC and non-ECC UDIMM DDR4-3200 memory"
Oh, so it does support ECC after all?
*goes to Asrock's website* "DDR4 288-pin ECC/non-ECC UDIMM"
Ok, so Anandtech just messed up. Or is the ECC support still limited somehow? As in, it works with ECC modules but doesn't actually use ECC? Or it works in the background but doesn't send a memory error event to the OS?
It's just the general wishy-washy state of ECC on non-professional AMD CPUs: it 'works', but nobody (neither AMD nor motherboard manufacturers) are actually willing to actually straight-up guarantee it is really working. QVL for the board isn't up yet, which is the ultimate arbiter of whether ECC will actually be supported, or remain in the realm of "well, if you plug in the sticks and it boots then great, but we won't do anything beyond that"
BTW, interesting solution for the PCIe lane distribution. The 4.0 lanes from the CPU that usually go to the m.2 slow are here routed to the second physical PCIe slot, prioritizing that instead of unnecessarily high-speed SSD storage. The m.2 is instead routed through the B550, hence why it's PCIe 3.0 only. Worth it IMO if one expects to use two high-speed expansion cards. Though one coud've split up the main x16 slot into x8/x8 instead of (or in addition to) this.
Too bad its an AMD board, otherwise I like this arrangement. Because on a server you will generally boot something like ESXi off a shitty media (like even a USB stick) and then run hardware RAID for the datastores. This allows plugging in more high-speed IO devices like raid cards or heck even some M.2 riser card or a 10GbE, since the board seems to forget including one. Really, who needs 4 1Gb ports, they could have easily done a dual 1/10 or something combination.
I’ll be getting this. I’ve used their Rack boards with consumer chips for years. Z97WSm and H97WSm still running in 1U’s w/ 4790k CPU’s. Never a hiccup from day one. Their BIOS allows overclocking too which is great for Digital Audio Workstations where 4-4.4GHz on Intel chips was a great boost. Also have the X470D4U w/ a 3700X that has been 100% solid since summer. Only wish the AST ASPEEED 2500 had more RAM. 16MB’s is barely adequate, but fine for non 3D Monitoring.

If you can get ASrock to comment on the TPM version, that would be awesome!ITproblems2020 - Monday, January 4, 2021 - link
Yes, I second this! This is crucial for our environments.Mentawl - Tuesday, January 5, 2021 - link
There's a TPM header on the board, so looks like you can put any of Asrock's TPM modules on it. They offer both a 1.2 and 2.0 module at the moment.ajp_anton - Tuesday, January 5, 2021 - link

Love my ASRocks. B550 will be perfect,
