Questioned cannot be answered. Why? Because you haven't a clue (or
didn't provide *us* with one) as to WHAT you intend to replace. Just
because his "machine" can support PC-2700 doesn't mean that is what is
installed. Also, you haven't mentioned how much free memory is
available versus how much pagefile (virtual memory) is consumed to know
if the increase in RAM would allow more programs to remain in memory
rather than get paged out to the far slower hard drive.

Since you aren't going to use the RAM anyway, what's the problem in just
giving it to the boy and letting him figure out if it helps him or not?
First check with only your old memory in the boy's computer. Check for
responsiveness after the install. Then see if the boy can reuse his old
modules with yours. If so, great. If not, he'll still have more than
before which means more programs (or more of each program) can be in
faster memory instead of the pagefile. Just go do it and test if it got
better.
