https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=219399 --- Comment #154 from Mark Millard <markmi@dsl-only.net> --- (In reply to Don Lewis from comment #149) It is my understanding that many Ryzen 7 boards allow ECC memory but do not use the ECC functionality: either the board is not wired or else the BIOS does not configure for it. For example: 7A32v1.0(G52-7A321X1)(X370 GAMING PRO CARBON).pdf says: Supports ECC UDIMM memory (non-ECC mode) (It does not say if the board is wired to allow ECC or not so I've no clue if a BIOS update might be able to enable support of ECC mode.) So it appears that: "Too bad you're not running ECC RAM, that would eliminate one potential silent cause of strange behavior" needs more context, such as "on a board that uses ECC mode (when appropriately configured if needed)". It may be that most folks would not have ECC ram put to use for their boards. (The X370 GAMING PRO CARBON that I had access to was turned into a brick by a BIOS update attempt and I do not yet have access to another Ryzen system.) -- You are receiving this mail because: You are the assignee for the bug.
