There is no problem there. Arch's default kernel configuration supports 
up to and including 32 cores.

If you are sure the RAM sticks are working fine by, say, burning them in 
a different rig, then you may have a problem with the memory controller. 
or something more insidious in the firmware controller. In any case, it 
sounds to me you need to RMI the box. I've heard SuperMicro has above 
average tech support...

I've never had problems with AMD-based servers. But the usual stuff in 
these parts is HP (now HPE), what used to be IBM (don't recall which 
Chinese outfit scavenged that part of the business), Dell and MSI-based 
white boxes.
