I've come across the subject of preventing interleaving and
investigated it myself years back to solve issues with the XLR8 SSE
card. There is no known setting or other way to turn off interleaving,
aside from not using identical sized DIMMs. If you just don't want to
mess with it anymore, you could get 4 64MB DIMMs and stick those in
Bank B. It'll deinterleave and give you 768MB total RAM. Not ideal, but
should be plenty for OS 9.
Since the Powerlogix card doesn't overclock the bus from the default
50MHz that Tsunami-based boards are rated for, I would suspect the
memory itself may have problems. Have you run the Gauge Pro or Power
Control memory tests? If you had the original 604e installed or a
slower G3/G4 the memory may have been ok at those speeds. But the G3 on
the Powerlogix upgrade pushes the system a lot more, and less than
perfect memory may generate errors. Interleaving stresses RAM even
further. I had it happen with my OWC RAM when going from a 350MHz to a
500MHz G3. Power Control suddenly started showing quite a few errors in
testing and OS 9 did become more unstable. Bought new stuff from Data
Memory Systems and haven't had memory problems since. MacGurus or
Crucial have pretty good reps for quality memory too. Or you could talk
to OWC about getting replacement DIMMs sent if your current ones are
showing errors.

Hey people,
I have a PowerTower Pro that I've purchased one of those new fangled
1GHz G3 upgrades from PowerLogix for.
After several hours of moderate configuration alterations and
continued bus errors and Finder errors, I have apparently resolved the
problem: I removed all of my RAM in the 'B' memory banks.
My DIMMs are all identical 128MB sticks from OWC. I would like to use
all of my RAM but have noticed in the past and now again here that
interleaving seems to cause more problems than it is worth. Is there a
way to completely stop it from happening?
I'm running OS 9, FYI.
Thanks guys.
