I was looking to purchase the ASUS Rampage III Formula motherboard. I wanted to install 12gig Corsair DDR3 hight-end memory. However, at the ASUS site I read a note saying "Due to Intel spec definition, DIMMs of DDR3-1333 or above are out of spec". I haven't been able to determine what this actually means, anywhere! Is it ASUS note saying that I have to stay with DDR3 memory below 1333? If I purchased faster DDR3 would it work? Would it be clocked down by the motherboard. Would I be wasting money if I went with faster DDR3 memory? I'm trying to get a clear answer to this footnote at the ASUS site.
Thanks for any clarity on this question.
