There appears to be a problem with DIMM slots 1 & 2 beside CPU2 on the motherboard. When I install memory in these slots and run Memtest86+ it causes the server to shutdown.
With all of the DIMM slots filled (2GB in each slot) the server will boot normally and will see all 32GB of RAM in the BIOS, but while running Memtest86+ the server shuts-down. I've tried installing different RAM modules and using another known good power supply, in both cases I get the same result. If I remove the RAM from these two DIMM slots, the server runs Memtest86+ fine.
I’ve tried several different memory tests (memtest HCI and memtest86) with the same results. When you put the CPU under load with memory in slots 1 & 2 beside CPU2 the server shuts-down. If I remove the memory from slots 1 & 2 beside CPU2 the server tests fine. I’ve replaced the memory in slots 1 & 2 beside CPU2 with known good memory, but the server still crashes.
I’ve been monitoring the on chip CPU temps with CPUID Hardware Monitor and they never get above 35 degrees Celsius.
Does anyone have any ideas on what could be causing this?
Thank you for your help.
