Argh!
I had to cancel that order on the motherboard. It appears the Rampage II Extreme is an excellent game motherboard and does pretty good on other things so long as you are happy with 6GB or less. But I wanted 12GB triple channel and that posed lots of problems.  You have to use much slower ram to run with high stability on that mobo if you going to have 12GB or more.

The other mobo that was on my list which I am checking is the ASUS P6T6 WS Revolution. Once I get all the vendor info for parts on it I guess then the order will go in again.  That one has fewer memory speed restrictions when trying to run 12GB or more.
