https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D219399 --- Comment #165 from Mark Millard <markmi@dsl-only.net> --- (In reply to Don Lewis from comment #163) Note: I can not claim to know for In: Physical Memory Array . . . Error Correction Type: Multi-bit ECC I wonder if it says that even with non-ECC RAM in one or more (or all) DIMMs. That section is not DIMM specific at all from what I can tell. But may be some of it is a summary over all DIMMs? (My guess is: no.) In: Memory Device . . . Error Information Handle: 0x002D Total Width: 128 bits Data Width: 64 bits vs. the older, narrower context's Memory Device . . . Error Information Handle: Not Provided Total Width: 72 bits Data Width: 64 bits The 128 bits instead of 128+8 or 128+2*8 bits suggests lack of ECC use at the DIMM in question. But I'm unable to test a Ryzen context for now so take my notes in this area as speculation (or as a suggestion for contrasting tests that I might have performed if the Ryzen system still worked, presuming some non-ECC RAM is available to substitute temporarily). --=20 You are receiving this mail because: You are the assignee for the bug.=
