I'm new to overclocking and just recently purchased an ASUS A7V133 MB and 1.2G 266FSB ATHLON. I set the multiplier at 10.5 and my system runs at 1400 (133X10.5) MHZ. I verified that the change took place by running a CPU benchmark. Why did'nt I have to close the L1 bridges on the CPU as per what I've read here ???
