So far the MSI B350 is minimal but the bios is nice, what you would expect in a gaming board. First thing I tried was 3200C12 settings and rebooted no problem but when I tried to push the CPU to 4Ghz it would not get even close with 2+0 cores enabled.

I am setup on the EK Supremacy Predator 240 AIO cooler and I am using TG Hydro TIM. 3.5Ghz all cores in CB15 @ 1.2v was working. I will hook up the AC unit today and try again for 4Ghz 32M @ 1.4v 2+0

This board will confirm the chip or the board with 1800X and 1700X IMC incapability of 2933+
