Hi Ohunt3r
I'm not with Laminar Research either, just another simmer in the UK and please initially following the advice given by my colleague Glenn from downunder.
On face value, your PC spec's look more than adequate and with 64GB of RAM and 6GB of VRAM, so the Mem file error. Err=19 is not something that you would normally expect to see.
However, there is still a possibility that a hardware defect could exist, so it may be wise to check the RAM memory with MemTest86 or similar. Please see following link for more guidance on how to use MemTest86 with Linux:-
