Asus prime b650m-a support ECC RAM

TrueNAS General

hello guys,

can anyone advise, asus prime b650m-a support ECC RAM. I checked the specification from Asus and also from customer care but they are not pretty sure.

Or any other board which support ECC DDR5 RAM with Ryzen processor, pls advise from your experience,

thanks a lot.

Based on my experience, I was able to get this motherboard to work with ECC ram:

ASRock B650M-HDV/M.2 Supports AMD Socket AM5 Ryzen 7000 Series Processors

But nowhere does it say that this board supports ECC. I was using a Ryzen 7700x and when I put ECC ram in, the TrueNAS GUI said it was ECC and I was able to use MemTest86 that you put on a USB stick to truly test if it was actually in ECC mode and it was.

In other words, I think it SHOULD work, but you might just need to test it and return it if it doesn’t or research some more.

ECC support on Ryzen is unofficial. Basically, you install ECC UDIMMs, an ECC-capable Ryzen CPU or “PRO” APU and… pray. :hand_with_index_finger_and_thumb_crossed:

The best you can do is to go for one of the few dedicated “server Ryzen” boards. For AM5 thet would be Gigabyte MC13-LE0/LE1, AsRock Rack B650D4U or AM5D4ID-2T, Supermicro H13SAE-MF.

For AM4, there’s a liquidation sale of Gigabye MC12-LE0 in Germany. That would be a much more palatable solution than AM5.

The best you can do is run the Pro version of Passmark Memtest86, if the chipset allows for ECC error injection (that’s a big “IF”!).

As for “AM5 / reliable ECC support / budget friendly”, it is one of these “pick ANY TWO” pickles. Which is why I mention the AM4 MC12-LE0 board…
(For information, with the MC12-LE0 Memtest86 Pro reports successful correction of ECC errors, but the events are not logged by IPMI.)
