I'm getting NOWHERE with my Rampage Formula/QX9650. I can up the multi to 10 and it works fine, but even increasing the bus 7 MHz to 340 Vista will not load. I've tried upping voltages to insane levels just to see if it helped and it doesn't seem to. I had this same CPU and memory at 420 x 10 on my Maximus Formula 12 hours + prime stable.

Since it will generally POST I'm wondering if maybe I have a Vista issue. I swapped from the Maximus without a re-install and recently went from an 8800GTX to HD4870. Removed the nvidia drivers, did driver cleaner, etc using the 8.6 hotfix catalyst drivers. Since the video card swap there are some issues. Sometimes it won't go into standby (S3) as set in the power properties. Manually putting it into standby works fine. Sometimes it will crash coming out of standby. I guess I'll hang on until the official 8.7 catalysts come out and do a re-install. In the meantime running at 3.33 GHz. Hopefully reinstalling Vista will get my OC back.

On a side note the Maximus was RMA to Asus and they have return shipped. It'll be interesting to see what shows up. It seems like the X48 should be > X38, so there must be some other issue with the OC.
