ECC support on Zen 4 AM5 platform

[jarnigan]

Is there a timeframe when MemTest86 will support ECC reporting / injection on Zen 4 AM5 platform?

CPU: AMD Ryzen 9 7950X
MB: ASUS TUF GAMING X670E-PLUS
RAM: Kingston Server Premier 32GB DDR5 ECC DIMM (Hynix M) - KSM48E40BD8KM-32HM

BIOS updated to latest (AGESA ComboAM5PI 1.0.0.5 patch C) and ECC in BIOS is enabled.

In Windows 11 wmic memphysical get MemoryErrorCorrection returns code 6 (Multi-bit ECC) so ECC should be working.

But MemTest86 isn't reporting ECC:
ECC Enabled: N/A (Unknown)

What version of Memtest86 are you using?

ECC injecting is blocked by most vendors on Ryzen. So unless you have a engineering sample CPU, it will likely never do injection.

ECC reporting should be possible. Let me check status.
(ECC support on Ryzen is a bit vague).

What version of Memtest86 are you using?

Using MemTest86 Pro Version 10.2 Build 1000

ECC injecting is blocked by most vendors on Ryzen. So unless you have a engineering sample CPU, it will likely never do injection.

In BIOS I have the option to set Disable Memory Error Injection to False.

After playing with memory frequency I was finally able to get some ECC corrected memory errors logged in Windows System Events: https://imgur.com/a/3dLdVcZ
Just to confirm ECC is really enabled and working.

We'll take a look at it.
