I recently acquired my friends old T7400, which although it hadn't been used in a few years, was working before it was left in the corner.
Running Ubuntu 16.04 LTS, Dual XEON E5420 2.5Ghz, 20GB RAM
I am getting this error message on boot:
alert! uncorrectable memory error has been previously detected in dimm 1 or 2. Press F1 to continue...
The dimm slots referenced also, change from '1 or 2' to '5 or 6' etc. I have swapped all the ram out, checked the contacts, and re-seated it.
My PC also hangs, becomes completely unresponsive in every way and has to have a hard reset.
I ran memtest86+ for about 3 days, making over 8 complete passes of the 20GB of memory, but didn't find a single error.
I don't think its anything wrong with the RAM sticks, as I have tried a few combinations, and the error messages don't repeatedly flag the same 2 sitcks. It's highly unlikely that the 4x1GB sticks that came with it are damaged, as well as the 4x4GB sticks I just bought from a reputable seller who reported them as tested.
I have removed and reseated the CPU. I have also replaced the cmos battery, but the problem persists.
Any ideas people?
I'm going to update the BIOS tonight, in case that's the cause.
Many thanks in advance.
