I've managed to get the Q9450 stable at 3.4Ghz with lower voltages then I had previously thanks to CrapCrasher's
post in the Intel Overclocking thread, prime95 ran for 14hrs 17mins before I turned the pc off in the morning.
vid:1.3375v(~1.37/1.38v with
vid special), I was using 1.4v before;
nb 1.367v(was using 1.715v before);
vtt:1.25(1.4v before);
cpu gtl 1/3: 115;
cpu gtl 0/2: 107;
nb gtl: 100(the
gtl setting was disabled).
I upped it to 3.5Ghz loaded into windows desktop but wouldn't fully load everything so I had to restart, now Windows is refusing to load(gets stuck at the black screen with windows xp and progress bar) even at stock tho it loads in Safe Mode. going to have to reinstall

was hoping to play with overclocking till friday night then reinstall over the weekend(been meaning for the last couple of weekends due to the cold boot and the 1394 net adapter issues).
