That's not 3200 though which seems to be the magic number thrown around. 2933 is what you are looking at with hynix.
@jigger the crosshair board has support +4000 since last agesa but nobody has achieved it. A microcode update won't change that.
Well I'll take that with salt, but the motherboard manufacter will have to add the supports based on the MC or they could have added themselves independently.
