I received the boards a few days ago and now had a couple of hours for first memory tests. Retail 11900K on aio, memory air
4400c17 at 4800c14
G.Skill Royal 4400C16 at 4800C14
G.Skill 3600C14 at 5000C14, IMC could not keep up with the load
at 5214 C15-14
at 5277 c15-14 direct boot Cinebench
More to follow, I still have some screens on HDD. 5333c15 posts but fails win enter, seems more of imc than memory issue
