AMD Ryzen 9 7900X Performance With ECC DDR5 Memory

[wertigon]

Are there any consumer motherboards that support ECC on AMD 7000 series? I run a homeserver with a 5950X and Asrock B550M pro4 supports ECC without issues. But apparently the newer 7000 series mobo's do not support it by default?

Asus got support across pretty much the whole range, do double check but seems like most Prime and ROG boards support it, and possibly more.

Other than that, seems like really sparse support unfortunately. It is time to make ECC mandatory, there is little reason left not to do it and you can always turn it off if you do not want it.

Michael Does this board (or any other ECC-supporting board) use LVFS?

...Asrock B550M pro4 supports ECC without issues.

Good to know; I've been wondering about that but hadn't taken the time to look it up yet. Still, while it may be apples-to-oranges, the perform impact of switching from DDR4-3200 CL14 non-ECC to DDR4-3200 CL22 ECC is going to be a bit more than 1-3%...

The data really show how pathetic it is that ECC isn't standard. The performance penalty is negligible!

I have often wondered, if I should begin to use ECC RAM for my NAS/server running 24/7. However, I have not really realized any issues being due to RAM errors.

Does anyone have any experience with running ECC RAM? Do you get errors/corrections reported in your logs regularly or at all? Is it really necessary in real life?

A defective RAM-module in my home server verry successfully messed up my zfs-pools on my NAS

Michael, have you heard any indications that 48 gig DIMMs with ECC will ever be a thing? I'd sure like to put 192 gigs in one of these boards.

Haven't heard but then again I don't deal too closely with the memory vendors.

I guess one of the questions or interesting bits remains (enlighten me if it's only me), if there's a significant or any kind of difference between the ECC-Disabled ECC DIMMS and Non-ECC DIMMS.
I suggest running these same exact test setup, with a few different as closely similar non-ECC supporting DIMMS, with as close if not exactly the same timings and specs otherwise, from different vendors.

Was going to do that but didn't have anything quite close to the ECC DIMMs tested.
