OK. Just looked at the Quicksilver spec sheet. It does indicate a minimum RAM Speed of 100 MHz. One more novice question: The spec sheet says 3 RAM slots and 1.5 GB Max RAM. However, the system profiler indicates 4 RAM slots (one empty). I'm runnning Mac OS X 10.3.7 (7S215). Is there any benefit to filling that fourth RAM slot? Thanx.
