So I have this dimm of 256mb PC100 RAM that simply will not work in my Sawtooth. I thought it was dead, or incompatible somehow (I have PC100 that won't work with Macs), but I dropped it into my G3 (early b/w, uses same RAM as the Sawtooth) and presto! It works. Ran several RAM tests on it, all came out fine. Anyone alse have weird issues like that?
