What is the entire sentence your system profiler gives you, when it states your "memory speed is 100? 100 what? Open System Profiler again and copy down the heading and description of where it says "100." It's probably MHz. If so, that's your limitation. > I have the package that the ram chip came in and it says > 133 speed. Is there something Im missing or did the chip get put in the > wrong package ? This is additional RAM you purchased to install, after you bought your computer? If you look at the package again, I think you'll find it says "133 MHz" not "133 mb." I think both Quicksilver models of the PowerMac came with "PC 133 SDRAM" memory modules. Those are described in the literature as 168 pin, 100 MHz RAM modules.
