Im looking to get a I7 3930k just for a rendering setup. I had a look at ark.intel for some info on the cpu and I was suprised to see that the cpu only handles low fequency ram (sort of - DDR3 1066/1333/1600). The motherboard that I plan to get supports ram upto 3000 frequency, if I get some 1866 ram will my cpu be able to handle it?
