I have some 1700 series routers that need to be upgraded from their current IOS versions but am having trouble figuring out what new version I can run. The biggest problem is identifying the DRAM amount in the routers. When I do a 'sh ver' I can identify the Flash RAM easily but not the DRAM. Below is the result from one of my routers:

I know this is a simple question but I'm just getting started with this stuff. Thanks in advance!
