i thought they removed the 2133 divider anyways? I run ddr3 2000mhz 9-9-9-24 I use the 1866 divider and 215mhz fsb.
Been awhile since i messed with it.
Anyways when your trying to set 2133mhz are your northbridge and hyper transport also changing? you will need to keep a eye on those as often they will reach for the sky Esp if using auto memory clock.
I have 10.66x divider in the bios... But I am an overclocker, I want to reach highest clock possible on the ram (Hynix, so they can get 2500+).
I tried also to low NB and Hyper transport...it's the same
