You probably won't have that exact speed listed in the bios as the memory has to run in a certain ratio to the BCLK, so just set it to whatever's closest (within reason.)

yeah. i understand that, but when i put it that high, the UCLK seems to be rather high and it wont load the os. and i cant see any voltage control for the UCLK? (whatever it is) after posting it gets to a black screen with a flashing _ top left corner :/
