I'm having issues with that same RAM pack with B450 Tomahawk Mobo (also MSI) and 2700. Would you mind posting your memory bios settings?
Ran across this while trying to get the same memory to play nice with my 2700 and b450 tomahawk Mobo. Would you mind sharing the memory section of your bios?
@ skootiebootie - yep, I've got a mystery 1TB spinning drive from current desktop that will transfer over, but it'll just be larger file storage.
@Zerk-parts still being delivered, nothing unboxed yet, still a chance for returns if anyone's got a red flag.
