You need 1.65 for 400*9? Is that sync with ram though? Thought 1.5 got you up to 450. Maybe thats with Async though.

Edit: I have no problems except sometimes I boot up and get a screen as if the video card memory has gone berkerk and can't get into the new bios for toffee. Can anyone else who has a usb mouse confirm this? I think and USB input devices stop the new bios from allowing you into setup.
