Thank you. I wish tech support were an issue, but this is an older box from an
ISP I was given, so it is more or less a project/fun box at this point. The RAM
is HP. (not yet HPE when this box was minted). Like I said, I have 2 sets of RAM
(36 2-Gig sticks total, all HP Part No. 405476-051)

I have attempted to run with as low a 8-Gig (4 sticks, non-interleaved, all
sticks in DIMM slot 1A of each bank per the manual) and it will not memtest in
that config. Adding a stick to slot 1B of each bank allows the test to go to 32%
precisely where the error begins, regardless of which sticks are used.

I'll keep playing with it. I've been through the BIOS (there are about 50
settings for RAM/ECC alone, most have 'Auto' setting). I'll double-check there
as well. The box was apparently working fine before it came to me (I don't know
how long ago the 'working fine' was through)

I'll keep fiddling with this. It is truly one impressive piece of hardware that
comes in a 100 lb. box and sounds like a 747 at takeoff (I think it has
equivalent thrust too given all the fans (17 at last count, 9 of which are the
80mm 6000 rpm jobs)).

Thank you again for your help.
