I used X11SSH-F (BIOS v1.0b).
I found IPMI will record uncorrectable memory ECC errors, if I change BIOS setting as below, please advise.
[Procedure]
Disable Hyper threading in BIOS >> Save & Give a restart.
Again Go to BIOS and Enable Hyper threading >> Save & Restart the system.
Then check IPMI Log, there are Uncorrectable Memory ECC Errors recorded.
The formal BIOS v2.0 "X11SSH6.C16" can solve this issue.
