That sounds plausible, and should be the first thing one checks if a system is flakey after adding hardware. also Digital circuits use more power as the clock speed increases, especially CMOS circuits [Power = FCV^2, F=frequency, C=load capacitance (of the chip), V=voltage], which could explain why it works at a reduced clock speed but not at full speed. It takes just over 5% more power to clock at 100MHz than at 95MHz, for a typical CMOS circuit. > I would definitely try using memory from a different dealer, and failing > that, I'd put a decent UPS on the computer. If it is a power supply problem (as opposed to a power service problem, i.e., the utility company), then a UPS will not be of much help. A UPS will give you a clean and stable line voltage, but it will not compensate for a power supply that just can't handle the load. - Bruce
