We've got exactly the same, but then with the X5DPR-IG2+/X5DPR-8G2+.
I've got about 25-30 running FreeBSD 4.6 - 4.11 running perfectly
stable, but the 3 that I installed 5.x on, (currently all 5.4-STABLE),
keep on hanging themselves up completely, even with no read load on
them, within a week.

CPUs range from 3.06 to 3.2 GHz, all of them have 4x1GB DIMMs, and
3 SEAGATE ST3146807LC 0007's...

I tried updating the BIOSes as well, with both a standard BIOS and one
given to us bh supermicro preconfigured fro com-console, so I could
flashed them with a remotely booted DOS floppy over com-console. :-)

Another thing I noticed: motherboard versions from before 2005 do not
detect sio0 on the right place: port 0x2f8-0x2ff irq 3 on acpi0 (the
normal place for sio1), resulting in loader/kernel comconsole going to
the right port and the userland comconsole going to the wrong port...

This problem does not occur on newer versions of the servers...
