Hi all,
I managed to get my Rampage Formula X48 stable at 500 FSB with my Q9450 @4ghz. I'd been having tremendous trouble getting there, but came across this thread which pretty much got me over the line. Thank you!
I have the profile saved so i can run the Everest Cache and memory benchmark and post it up a little later on.
Here is a CPU-Z screen shot:

Here were the settnigs i used:
