How can you tell if you should use the fast or slow 4G version of s905x2?

And what are the signs that you’re using the wrong one?

Ex.  
I have a T905Q and ps1 plays well with most games, some pauses but n64 is unplayable for most games.

Any help is appreciated, my first build. Having a lot of fun.
