advice on 3660 IOS upgrade

I have a 3660 running IOS 12.2(2)T (IP Plus). It has 64MB of RAM so there are no 12.3 images that will work. Most 12.2 images have advisories or also do not work with 64 MB RAM (no current T train images are appropriate). Should I consider increasing the RAM or figure out the best 12.2 to use?

Re: advice on 3660 IOS upgrade

I was in the same boat as you. I have a 3660 currently running IOS 12.3. I was having some problems with differential delay and it came down to having to upgrade from 12.2. I finally decided to just upgrade the RAM and install 12.3. It fixed a lot of problems.

Chuck - Thanks and a quick follow-up if you're still following this...I hate to be dumb, but is there an easy way to know if the current RAM is using 1 or 2 slots (other than shutting down and physically looking)?

I had to physically shutdown and look.
