I suspect there is a typo in your code defining m. You have a lower case i in the expression but are using an upper case I as an iterator. Is this really what you meant?
With this code, you've asked Mathematica to compute a symbolic answer as the determinate of a very large matrix. Consequently, it should not be all that surprising when your system runs out of memory. It is hard to understand why you would want a symbolic answer that will have several thousand terms.
