My P3B-F won't do jack when overclocking, my PIII 700 will only be stable at 840 (120FSB) on this board, i plugged it into a Soyo SY-6BA+IV and it was rock at 882 (126) and it was almost fully stable at 933 (133) which wouldn't even boot windows on the P3B-F.. both were using the same slot converter and cooler,(G'Orb) at default voltage.
I might just do a board swap!
