Would you like to never see a PSOD screen again? I mean, who would? Elevated heart rate, restarted VMs, explaining the reason, searching for the reason, trying to distinguish a false positive from an actual alert. You definitely have better things to do.
When looking at memory failures (DIMM is what I am referring to in this instance) uncorrectable memory errors is what brings most of the trouble and requires DIMM replacement but the majority of the errors are correctable.
Each BIOS version brings improvement to handling hardware. That includes correcting memory errors. Meaning, you can avoid pesky hardware replacement windows for much longer if not forever.
To keep your BIOS up-to-date use LCM. If you do opt for a manual process remember to always upgrade BMC first and only then proceed with the BIOS. BMC upgrades are non-disruptive. BIOS upgrade does require a host reboot.
And as always, keep your NCC up to date (current NCC version is 220.127.116.11 and some false positive alerts in relation to DIMM errors are resolved there).
Stay safe and up-to-date!
