**update**
I'm now using the xmp II profile that comes with the ram which is running at 5600.
So far so good, passed the memtest with no errors.
When I check cpu-z.
I see a dram reading of 2800, and the individual reading for both sticks of ram under xmp is 2800 also.
Timings are 36-36-36-76.
Given the ram is running Dual mode, I'm assuming this is what I'm supposed to see and the xmp profile is working?
