can you use faster DIMMs, say 2100PC, on a machine rated for slower DIMMs? i got new memory for one of my faster machines and would like reuse the DIMMs to beef up the memory on some of my older machines (which still take DIMMs, just slower rated DIMMs). pete -- GPG Instructions: http://www.dirac.org/linux/gpg GPG Fingerprint: B9F1 6CF3 47C4 7CD8 D33E 70A9 A3B9 1945 67EA 951D
