I've seen allegations that for some vendors, text like this on their non-server/workstation boards turns out to mean that ECC modules will work in the board, but without the actual ECC function.
- adrian_b 3y agoWhile there might have existed such vendors, nobody provides more information than that written above in their MB specifications, so it is difficult to know for sure which is the case, before buying a MB. The only way to gain more confidence is if the downloadable MB manual has an exhaustive description of the BIOS options. If in the BIOS options there is one for enabling ECC and perhaps additional related options, e.g. for configuring scrubbing, only then there is complete certainty about ECC support in the MB. However most recent MB manuals no longer have a complete BIOS description, so they may be not helpful. At least with the ASRock or ASUS AM4 or AM5 MBs that I have used, whenever "ECC & Non-ECC, Unbuffered Memory" was specified, the MB really had ECC support.
- formerly_proven 3y agoSometimes the OS is unaware of ECC support on the hardware as well, e.g. Linux doesn't/didn't enable the Intel edac driver on i3's running on server chipsets using ECC memory, despite the CPU actually utilizing ECC in that scenario (they simply forgot to add them to the whitelist). So edac-util went "No ECC MCs found!", even though the platform worked.
