RAM - Dragon Center

[GeoHandle]

I’ve had problems with my computer involving RAM that I’d tried various ways to identify and fix, I thought I had at one point and then found out I hadn’t, so eventually I gave up and just decided to use the two ram sticks in single channel. I won’t go into detail on the problem in this post since I’ve already made multiple posts for my problems with the RAM, but basically I can only use the first two slots in my motherboard for RAM (either stick in either slot, or both in the first two slots) with my cpu (3700x), dual channel worked, though not to the rams rated speed, when using a lower end CPU (3200G), but not on the original 3700x I had nor on the new one I’ve replaced it with. 
I just noticed in MSI Dragon Center that though the ram sticks show up as the same set, the xmp shows as different speeds. Could this be the cause of the problem, and if so does that means the RAM set should be sent back, or is this just from me using different xmp speeds when using the sticks separately?
