One place you might check is under /var/lib. I think there may be a
/var/lib/crash directory which contains core dumps.

Another option is to try Advanced Cluster Breakin, which runs other
tests besides memory.

I've had it find problems that memtest hasn't (and vice-versa).

If the system supports IPMI, check those sensors and logs, there may be
something useful there. If you don't have IPMI, there may still be
something in the BIOS logs (how you get to those varies wildly, you may
need to boot into the BIOS to do it).
I hope that helps!
