Adding memory to a Cisco 2620?


I wnat to upgrade the memory on my Cisco 2620 router. It looks like it has 48mb, is this possible, can you get to 24mb dimms or is it using a 32mb and 16mb?

Does Dimm 0 and Dimm 1 have to be the same size?

Here is my config, I want to get an IOS that supports VPN's, but I think I need around 98mb.

2620 supports a Maximum of 64MB DRAM

DIMM 0 and 1 need not be the same size. See if your IOS supports "show c2600" to see DIMM configuration you have.
