- Doug here,

-
- As I said, the customer will be able to pick their own oscillators, depending on
- how able their Falcon is to cope with the different rates.
-
- I never said it wouldn't work at 50MHz - I just never said it would!
-
- You could even try a 64/32Mhz combo if you use enough heatsinks.

-
- The top rate varies between accelerators as much as it does between machines.
-
- PowerUp2 was unstable at 32Mhz on our prototype Falcon - yet it's quite happy
- at 48Mhz with the BSS card. It's a 'suck it and see' scenario. It has a lot to
- do with interference from other circuits & the quality of the logic gates.

-
- The problem is quite solvable - see one of my other replies...
