I have a Rampage IV Extreme and just recently upgraded to a Ivy Bridge E (from Sandy Bridge E.)
I know IVY-E supports 1866 RAM, but from what I am reading it's with 2 DIMMS (I have 4 installed). I have it set to 1866 and CPU-Z reports 933mhz so it appears its running all 4 DIMMS correctly.
Is this actually true or is it just reported that way? Why say it only supports 1866 with 2 DIMMS if it works with 4?
Thanks
