Looking at an issue with a DELL Poweredge 2650 which had weird RAID problems,
whilst it was down for looking at that I stuck in a couple of GB of RAM, and
It fails memtest86 checks, the failure is always the same distance from top of
memory, and occurs with known good memory. Just like the problem described
here by someone else....
Failing on address 000bffedc80 3071.8MB
Swapped memory around a but
Failing on address 0007ffedc80 (2047.8MB)
Swapping memory in any valid config gives the same error, same distance from
top of memory.
The resolution above suggests a problem with the RAID controller firmware, so
I'm in the process of updating both RAID firmware and BIOS revision.
Does this sound like a plausible resolution, and a sensible test case? (Short
of replacing the box)
The DELL website recommends but doesn't mandate the Perc 3/Di firmware update,
which seems wrong to me, unless I'm missing something, either it should be
mandatory, or this isn't a good/complete explanation of the problem I'm
Can I easily run DELL diagnostics (currently Debian is installed on the server
with no diagnostics partition, I didn't see a readily supported method of
running the DELL diagnostics), but I'm sure I use to boot them from CD many
moons ago when I last did this.
