Thanks for the info Squid, I have been having a lot of issues with this setup and ram is just the latest. 2133MT/s was the default setting on the bios so I went with it. Next week I will be upgrading to a Gigabyte x399 pro with a Threadripper 2950X, maybe I need to rethink the ram for that motherboard. I will look at that boards QVL list before I buy more.
