Hey

Man, the mainboard is dope!!!! Yes, these things are compatible with the mainboard, you can (almost) always find them in the QVL (Qualified Vendor List) of the manufacturer: Here is the link to it https://www.asrock.com/mb...

By the way: the RAM are beautiful and absolutely TOP! I just installed them in my new 10900k / 3080 gaming monster :D

Wish you happy holidays

Cheers Shen
