- The problems you'll probably run into will be
-
- machine locking up
- parity errors
- read and write errors

- Your machine MAY though be able to sense the slower simms and compensate
- for it by automaticly inserting more wait states. Most machines though
- (older ones at least) have the wait states hardwired via jumpers on the
- mother board.
