Good afternoon!
There is an old hp ML370 g4 server, in the morning it gave an Uncorrectable Memory Error (System Memory), I found it on the Internet, change the memory bars, replaced (there were spare ones), but it never started, how to reset the error?

Answer 1

Check modules, look for faulty ones.
if it doesn't help - reset NVRAM

Answer 2

Resetting NVRAM did not help much, so the motherboard most likely died.
