Well can only get one set to post I guess the sub timings are not close enough and I am not too keen on pumping over 1.5v into the ram to see if that can get it to post and boot. Not with this Corsair Ram Cooler alone... So using one kit, Really do not want to return a kit I touched, took out of its packaging not fair for the next owner. So second kit went into my wife's pc. She will have to use the Ancient i7 970 ES with 48gb of ram for video encoding/ripping/editing. G.Skill not sure if they read my email or just the subject, but they said my kits are compatible with this board I would have to run them at 3600 if there is no support from MSI yet, and hit msi up to get support. Kind of going hmmm. But imagine my z490 board needs a bios update to run on 1t, on my Z690 with a single kit it runs at 1t G1 So that is pretty awesome. Made some big jumps in performance in some on the FPS lows like the CPU is like oh finally I can keep up with your resolution with shadows and npc ai. Pretty interesting couple of days.
