I have a 7120 and need to determine if it can have more memory installed. The 'show version' gives 229376K/98304K, and Total: 191252512, Used: 170820752, Free: 20431760. Opening up the box, however, show that both DIMM1 and DIMM2 have Samsung M374s1723CTS-C1H SDRAMs installed, which are 128MB SDRAMs. I can't reconcile the output of 'show version', 'show proc mem', and the part number of the installed SDRAM modules on the mother board. It looks to me as though it has 191MB and could take a 128 MB upgrade to 256, but maybe not. Are there any good links on determining installed memory on 7100s?
