I successfully added PC100 to my PC66 (but only after finding that the maximum stick size supported was 64MB. I had to swap the 128M I bought. I also had my original RAM go "bad", which resulted in intermittant crashes.
I highly recommend running "memtest86" (from a boot floppy or CD) in the highest mode to make sure you "exercise" your new RAM. It will write and read with various data patterns that (hopefully) shows up any issues with contamination between adjacent memory bits.
