hi i recently built myself a new build of a msi b350 tommahawk artic Ryzen R7-1700 ,EVGA GTX 1080Ti + 2x8gb Corsair Vengance LPX 3200mhz.
when i 1st put PC together i was able to get the ram upto 2933mhz , it would not let me do 3200mhz and i could put up with that , so i bought another 2x8gb Corsair Vengance LPX 3200mhz kit , after fitting them the only way i can get PC to post is to leave the ram at default speed.
i have tested the PC with 4x8gb Corsair Vengance LPX 2400mhz out of my other PC (I7-6700K , gigabyte Z270 gaming ultra +GTX1080) and got same problem that it would not boot above 2133mhz with 4 sticks of ram installed

A new bios was recently posted. It might be worth giving it a try, BETA VH73. I havent flashed it on to mine yet but will do over the next few days.

Have you tried setting memory voltage to 1.4v ?

i put the new bios on mine today and now my g.skill 3600c16 ram seems stable at 3466c16 using the a-xmp profile 1 and manually setting the vram volts to 1.38. Still cant get it stable at 3600c16 but its an improvement over the 3333 it's been sat at since day one.
