Working on dell lattide C600 with the original 128mb pc 100 memory in it. I tried installing another 256mb memory with the 128mb already in, would not reconize the 256mb, just the 128. Tried to install 256mb in slot 1 by itself and get the flashing lights. Put the 128mb back in and it works. The only other thing that does not work is the cmos battery. I am about ready to replace it soon. Can the cmos battery cause memory upgrade problems? The 256mb is known good memory. Any help would be appreciated! Thanks.
