GA-Z170X-Gaming 7 LED Code 51

[ofmrew]

I have used Anarchy 2-Pack 16GB PC4-17000 DDR4 DIMM memory since 28 Oct with no problems. This morning I got a Debug Code of 51. This memory is 2133. No changes were made to the BIOS and the computer ran fine last night.

I want to thank those that responded; however, the problem cleared. I moved the computer to try reseating the memory and in the move I also reseated the HDMI cable which seemed loose--breaking the golden rule of debugging never to make more than one change at a time. I do not know if it was the reseating of the memory or the reseating of the HDMI cable or just that the room got warmer that fixed the problem.

While your PNY memory appears to meet the boards memory requirements, if its not on the QVL, you can see intermittent problems such as this.  I'd disconnect from power, remove the MB battery and reseat the RAM.
