Hi Community,

Any ideas?

2 Ripjaws PC4-19200 4gx2 DDR4-2400

Mixing memory (from different kits) is always a lottery, the memory might or might not work together (properly).

Try memory from one kit in 1st and 2nd slots, and the memory from the other kit in 3rd and 4th slots. If that doesn't work swap the memory from slots 1 and 2 into slots 3 and 4, and memory from slots 3 and 4 into slots 1 and 2.

If still having issues, raise DRAM Voltage by 0.05 V, and don't exceed 1.35 V.

If still having issues, raise VCCSA Voltage by 0.05 V also.
