Which means that the L3 Cache on your CPU is possibly going bad.  May just be a result of living on an Indian Burial Ground and a one time thing, but if it continues, your CPU is shot.

just upgraded the CPU's.

Perhaps there is a bad connection to one of the CPUs. If it continues I'd remove and replace both, check the sockets and CPUs very carefully with a good light and a magnifying glass, or take crisp closeup photos from a couple angles, magnify and examine.

how do I tell which one is having the issue, there are 2 processors on this board.

If the motherboard logging isn't helpful, I'm guessing the only way to tell would be to run with only one CPU, and swap it out with the other CPU after a period of time.
