I just got my Tbird 1133 (266mhz version) with an Abit KT7A-266fsb board, 133RAM and a basic fan setup. I want to mess around a bit with overclocking but am not sure if the chip is locked or not. It generally runs at 8.5 x 140 (1190) @1.81v stable but as soon as I try to go any higher on the multiplier or FSB, it won't boot and I have to clear the BIOS. That's without any other optimization settings either. Is it because the chip is locked? At 1190, it runs no hotter than 47 deg C and idle at 40 deg. And lastly, how much should I increase the voltage if I want to try 1260? My next purchase is a better fan setup so I won't be playing too much yet. Thanks for the help.
