Menthol - Thanks for the advice,
1) "Yes" The menory set was the OVL list. The Memory is Model F4-2666C15Q-16GRR
" G.SKILL Ripjaws 4 Series 16GB (4 x 4GB) 288-Pin DDR4 SDRAM DDR4 2666 (PC4 21300) Desktop Memory"
2) "Yes" Setting to Optimized Defaults I still get the error.
See MyPCPartPicker Build write up -
https://pcpartpicker.com/b/fTccCJ - system was awesome for awhile untill this freezing issue came up.
So we are then suspecting that what ever the cpu/memory communication reliability issues is.... use has made it worse?
I'll follow your suggestions and report back.
