Installing memory above system max

Hi,

I have an older PC that has 128MB RAM on the motherboard and has a
socket which will take a 144pin, SO-DIMM SDRAM module. The system
spec's say that the max memory is 256MB total. (In other words, I'm
supposed to be able to put up to a 128MB DIMM in that socket).

My question is as follows (and I realize there might not be a
definitive answer as it could depend upon the system's h/w design):

If I install a 256MB DIMM (instead of the 128MB specified max) into the
socket, in general, would this be a problem? Will there be an extra
address line left "floating" and cause unpredictable consequences?
Note, that I'm not expecting to actually be able to address the
additional memory, it's just that I happen to have a spare 256MB module
on hand and would like to use it.

The system is a Panasonic CF-81, 850MHz Pentium 3.

Regards,

MB

From our experience as a dealer, most computers let you access the
maximum RAM amount allowed with no issues. Some computers may not
recognize the module if it's incompatible. So go ahead and try it.
 
KC, thanks for your reply. I'm going to give it a try this afternoon.
