Hello community.
We are running, Centos 4.8 on SuperMicro SYS-6026T-3RF with 2xIntel Xeon E5630 and 8xKingston KVR1333D3D4R9S/4G
For some time we have lots of MCE in mcelog and we cant find out the reason.
The only thing that shows there (when it shows, since sometimes it doesn't seem to) is a hardware error. You *WILL* be replacing hardware,
sometime
soon, like yesterday.

Bad news: you have *two* DIMMs failing, one associated with the physical CPU that has core 53, and another associated with the physical CPU that has cores 32-35.

Last night we'v made some research to find out which RAM modules bugged.
To be noticed we have 8 modules 4G each.
<snip>
Finally we'v placed last 2 modules...and no errors. It should be noticed that at that step we have exactly the same modules placement as before experiment.
Sounds strange, but at first glance looks like smthg was wrong with modules placement. But we cant realise why the problem didnt show for
the first
days, even month of server running. Noone touched server HW, so i have no idea what was that.
Now we are just waiting will there be errors again.
I'm sure there will. Reseating the memory may have done something, but there will, I'll wager.
Here's a question out of left field: who was the manufacturer of the 4G DIMMs? Not Supermicro, but the DIMMs themselves?
