I've been successful installing a PC100 128MB stick in the slot on the MB in
place of the default PC66 64MB stick that's installed at the factory. But a
known good PC100 256MB stick from a 600X freezes the system dead and it
refuses to boot. I've tried every combination of memory I've got lying
around the shop in the 770Z, but haven't been able to get it past 512MB
total with two 128MB and one 256MB.

A CPU upgrade is on my list of things to attempt on the 770Z, right after my
daughter's wedding! ;-)

One must have one's priorities.

Regards,

James
