I have some questions about overclocking RAM on my motherboard. I bought 8GB thinking that I would be running them at 1066mhz, but to my surprise they only clock at 800mhz. I heard that with my kind of build it clocks the memory down when you add more then 4GB of RAM. Can someone please give a concrete explanation? Is there a limitation on the mobo that causes this? Is it even possible to run them at 1066mhz or am I hoping for too much?
