Unless you have a server, you should not be concerned. Your querie was limited in info, and, I suppose I should suggest some app that would detect such. Sorry.
In case you don't have a server, here are some links with info on error correction code memory.

As far as a program to inform you of the system you are working on, and the ram installed. Check the links I posted. They all go somewhere, eventually.
Aida did not help me. It was of limited use. Must have been the free version I tried.
