B650 board with Zen 5 and ECC memory?

Thanks for your response!

Should be fine in principle. In practice, I’d plan for validating SECDED with every BIOS version the board runs. Don’t know of any ProArt B650 ECC tests but Wendell recently found the ProArt X870E wouldn’t post with ECC DIMMs without a BIOS update. At least one ROG X870E’s failed to deliver claimed ECC support as well.

You mean testing it with something like memtest86 (I don’t know if it supports ECC on Zen 5 yet)? Or just checking if it’s reported as ECC by the kernel? Is there a safe way to check if there are correctable errors reported other than overclocking it?

ASRock’s ECC delivery seems more consistent. The boards are a good bit more expensive but, if you need 5 or 10 GbE down, Gigabyte’s ECC support on their upper end B850 and a couple of the upper end X870Es might also be worth considering.

Going with ASRock’s Taichi Lite was exactly my plan for a while. It was even one of the few boards which still had 6 SATA ports, which I was also looking for. However, I recently learned that ASRock boards unfortunately don’t offer individual SATA port enabling/disabling like ASUS does which is quite important for me. I then saw people reporting here and on Reddit that ECC worked on ProArt, mostly X670E but I think I saw two users which also said it worked on B650 (actually, one of them was B650 TUF, I just found it here).

Wouldn’t surprise me if B650 production stopped last year.

Really? I thought stopping their production would be announced somewhere online and I couldn’t find it. Because I don’t know if a B850 board will be available for a similar price soon.
