Hi Andy,
Sounds to me like you have 1) a flakey board, 2) the memory is not
identical. We never use kingston for a variety of reasons, but you
really should see if the part numbers are identical. The timings on the
drams is critical. I would never mix capacities. 3) Make sure the memory
is all the same i.e. registered e.c.c. or non registered e.c.c.
I don't think its the power supply, but it can be.
Regards,
Lanny

Hi Erich,
Why would the power supply be suspect since the machine is perfectly stable
with 64 GB of memory in it?
The server won't stay up long enough to run memtest.

I am having trouble with one of our servers and I'm not sure what to try
next. It has a Supermicro H8DGi-F motherboard with two 16-core AMD
processors and two memory banks, one for each processor. When I
originally
built it, I only had one processor and 40 GB of ram. Everything worked
awesome. I recently upgraded it, adding another processor and another 40
GB
of ram. It was incredibly unstable and constantly rebooted within minute
or
two of uptime, sometimes it wouldn't even boot all the way before
crashing
and rebooting again. Seemed like a memory issue so I scaled it back to
two
processors and 32 GB (4x8GB) of ram. Worked well so I added the
remaining 8
GB sticks I had, bringing it up to 64 GB. Still worked great. The sticks
I
had left were a mix and match variety of 8GB and 4GB sticks. Thinking
maybe
there was some problem with mixing them, I ordered more 8GB memory just
like the ones in the box. While waiting for the new memory, the machine
performed great with no issues. New memory arrived and I added two more
8GB
sticks. Immediately the constant crashing returned. It seems really
unlikely that I got bad memory in two separate orders. Does anyone have
any
other ideas? Again, its perfectly stable with two processors and 64 GB of
memory but goes nuts when I more.
could it be caused by the power supply?
Did you run a memory test?
If possible, try different power supplies.
I really appreciate the help!!
Motherboard: Supermicro H8DGi-F
CPU: 2 x AMD 6274 (2.2 Ghz 16-core)
Memory: Kingston 8GB DDR3 1333
No ECC?
