Nope. The system will take 256MB modules in 11-bit Column Address, in
selected banks. I am kinda wondering if there's something strange about
the manual (I'm looking at page C-19 of the 805-3158-03 05/1999
SPARCengine Ultra AXi OEM Technical Manual from sun.com). I seem to
remember the Tatung U10 clones having a different layout, so maybe I just
put them in the wrong bank.

As far as Crucial is concerned...

They have 64MB, 128MB, and 256MB modules. I have a pair of 256MB modules
in here from another vendor, so I know they work (and I just saw Mike N's
response to that effect as well). 

I also see that the OEM manual says 60ns only, and these are 50ns. But I
can't imagine that being the problem. 

Maybe I should just sell the 256MB sticks and buy a pile of "128MB" 256MB
sticks. :) Or just settle for 768MB right now. Yeah, as my gf says, my
life is hard. :-)
