--Apple-Mail=_5709D9CC-F173-4A15-ACA5-3D4E15BD7C9E Content-Transfer-Encoding: quoted-printable Content-Type: text/plain; charset=utf-8 Hi all, both, the mainboard (with recent firmware P3.10) and Ryzen 7 CPU should work with ECC RAM (while not officially supported). RAM is KSM26ED8/16ME DDR4-2666 ECC DIMM. AFAIdmesg and dmidecode do not indicate ECC (see below), I think. Data path should show additional ECC bits. There is only one related BIOS setting, I=E2=80=99m aware of. Changing this from AUTO to ENABLED makes no difference. Quick answer would be very helpfull.
