This does not generally extra fragmentation with one possible exception. The additional RAM will cause Windows to increase the size of the swap file. Why it does, I have no idea as it makes no sense. You will notice your hard drive space decreases a bit. A little math tell me you might see your space decrease by a little over 1 meg as the swap file tends to be 1.5 time RAM size. It's possible the swap file is fragmented a bit , however.
