[rescue] Mixing CPU modules with different part no.

[Chad A. Chance]

I have run mixed part number modules and mixed cache-controllers in the past
with no problems.

Of course with any statement like this I have to say "your mileage may vary"
and really the only way to know for sure if those 2 particular modules will
work togethor is to try it. You won't fry anything by trying it, the worst
that could happen is the machine will be unstable.

Good Luck,
Chad

Hello Gurus,

I read about the general module configuration rules
from http://mbus.sunhelp.org/misc/genconf.htm. It says
we should be careful when mixing module with different
part no.(even of same type) and we "should not mix
MXCC cache-controllers of differing major revisions,
on the same MBus/XBus".

I currently have a module(part no.501-2904) running in
my SS20 and thinking of adding another module to
it(part no.501-4130). By refering to this page
http://mbus.sunhelp.org/modules, since 501-2904 and
501-4130 have similar MXCC ver.no., furthermore MBus
and XBus speed also the same. Does this mean I have no
problem of mixing them ?

By the way, what does the 2.3 and 2.4.5 in "501-2904
SuperSPARC-II 2.3" and "501-4130 SuperSPARC-II 2.4.5"
means ?

Thank you
