Pros: Nice quality. Thats about it. Run it in non xmp, everything is fine. defeats the purpose.

Cons: Have an Asrock X570 board and a 3900x. With XMP profile, it posts at 3600 CL14 and seems to run fine till I play a game or do something tasking. It bombs shortly after. When it does make it through a benchmark, they come out worse then when using my 3200 CL16 old memory.

Overall Review: Take a chance if you have something like a godlike board. Otherwise, waaay too much money for a roll of the dice. I'll be returning these for 3200's.
