Does AMD 670/650 support ECC and USE ECC?

Does AMD 670/650 support ECC and USE ECC? Looking at setting up some ATX workstations for the office. will not need a ton of cores. just need modularity of ATX and reliability was looking at the 7600X IDK if there is equivalent Epyc so my thoughts are an Ryzen 5 7600x with ECC

I believe all Am 5 Cpus support ecc but not all motherboards do.

It appears AM4 and AM5 ECC support’s almost entirely an AGESA thing rather than Intel’s odd arrangement where the chipset influences behavior of a bus it’s not connected to—ASRock claims ECC support on A620 mATX, for example, though I don’t know of a third party fault injection report confirming SECDED on the boards.

MSI and, so far as I know, Gigabyte haven’t exposed the ECC enable as an option in their BIOSes, though maybe some of Gigabyte’s server or industrial boards have it. Out of the ASUS boards I know offhand ECC support’s restricted to high end SKUs.

Keep in mind DDR5 adds read CRC and thus offers protections with only on-die EC2 which used to require bus EC4.

is that how actual error correction is confirmed?

yeah i’d be looking at asrock for mobo brand anyhow

EDIT: found an asrock rack board sans 10gb there is a version with 10gb for like $120 more

It’s the most structured testing option. A more basic approach that just verifies something’s happening is cranking up a DDR overlock and looking for corrections in the system log.

The B650D4U accepts UDIMMs, not RDIMMs.

ASUS claims that all their X670 and B650 boards support ECC UDIMMS when coupled with an AMD Ryzen “X” series chip. Meaning no Pro series chips and no APUs.

ah! thnak you! https://www.amazon.com/Kingston-Branded-Memory-4800MT-KTH-PL548S8-16G/dp/B0BV3B4YQ9/

i have not seen any PRO 7000 series yet. i did realize my am4 asrock rack board requires PRO CPUs for ECC so unless i figured out how to do that structured test i probably need to upgrade those old systems to PRO chips to get that ECC working.

It depends on the motherboards and AGESA.
Best bet currently is probably with Asus as they claim ecc support on all their X670E boards,
except for the ROG strix X670E-i gaming.

so does asrock, at least all the 670/650 boards i looked at. i would not advised buying asus. I say that having great luck with them over the decades, even had one board get struck by lightening, burst in to flames and did not flinch and continued to run fine sans active modem connection since the modem card was literally burning on fire.

With Asrock when their boards first came out they did support ECC on certain boards.
However with a couple of AGESA´s further idk what the current state of that actually is.

Maybe Wendell could shine a light on that.

i have been saying stop buying ASUS for years now.

the ECC on consumer gear issue has been a roll of the dice since AM3. the thing is MOST (not ALL though) AMD CPUs support ECC in some capacity. but getting boards, BIOS revisions, and actual RAM, to all be willing to activate it at the same time is a roll of the dice. and if you do have it functioning, BEWARE any further BIOS updates.
