It looks like you have more than 64MB of Memory, Looks like you have 128MB. With 128MB you should be able to upgrade your IOS to a version that supports a higher CME..

Have a look at the CME and IOS compartibility matrix...

Having said that, there is nothing wrong with having more memory..So yes you are on the right track
