  • ECC memory and totalwidth

    LS,

    I am having a hard time getting ECC memory to report the proper totalwidth as of late.

    When using in dmidecode on linux or wmic on windows server 2019 both of my 2 recent attempts with
    4 x Kingston KSM26ED8/16ME (64gb total) tried on a ASrock x570 creator with latest bios and ecc enabled
    and
    4 x Cruicial CT16G4WFD8266 (64gb total) tried on a Biostar x570 GTA latest bios and ecc enabled
    always report a totalwidth of 124 rather than 144

    The CPU for both setups used was AMD Ryzen 9 3950x (supports ECC although not advertised as such)

    The AMD x570 / AM4 support ECC and ECC error reporting

    Is there anything I am doing wrong?

    I am really looking for having memory reports show the correct totalwidth

    Hope this community can shed some light on this.

    Kind regards

    Don't know. It is a niche area.
    It isn't something we have looked at in detail.
