That explains it.  I assumed you still had the original 604e chip in
it- the only 604e chip that ran the bus at 46.7 MHz was the 233 MHz
board.  The 200 MHz 9600 ran at 50MHz.

Hmm. I see.


The CPU daughtercard determines the bus speed in the 7300-9600
machines, so depending on the settings, it will be set to anything
from 40-50MHz (though the later PowerLogix and XLR8 G3 and G4 boards
gave you the option of going up to 62 MHz- some [very few] of these
machines *will* run at those speeds).

Gotcha


Sonnet is known for using
conservative bus speeds on their G3 upgrades as most companies' 300
MHz boards are set at 50 MHz (6 x 50).  Yours is apparently 46.67 x
6.5 = 303 MHz.  One of my users has one of those in a PowerCenter.

Well, in theory at least, this gives greater compatibility, which is important for them as you can't actually alter it on the card like other vendors' cards.
