- There's an excellant chance that a certain amount of the slower spec'ed
- memory will work. Just don't expect a guarantee. The faster memory
- has been certified to run at that speed. The slower memory chips were
- "fall-outs" from the faster tests. As I understand it the same goes for
- CPU chips. You can expect a certain amount of success from running them
- faster, but be warned that if it does you can feel lucky.
-
- I am also using 100ns 1x9s on a faster system. It's been running just
- fine for the last year.
