Any suggestions for ECC?

Would you suggest going with an ASRock Rack motherboard, even for desktop use, like you used here? https://www.phoronix.com/review/amd-ryzen9-ddr5-ecc

I'm strongly tempted to get a Zen5 CPU, but am unsure of the motherboard.

I haven't yet tested ECC with any Zen 5 desktop CPU. But yes in general with Zen 4 that ASRock Rack and Supermicro boards have worked out well. With time will try out ECC on Ryzen 9000 series.

Zen5 appears to officially support up to DDR5 5600, but unfortunately all of the ASRock Rack or Supermicro boards I looked at only supported DDR5 5200.

I may wait for new Zen5 boards, or maybe take a gamble on something like the Asus ProArt, where I saw comments online indicating that ECC is (unofficially?) supported.

Looking forward to Ryzen 9000 ECC benchmarks.
