You should use 64 bit if possible but if you're seeing 3.2GB, it's more
likely that your motherboard is not capable (I have one of those here
right now).

It still is, even with with 64 bit. If your motherboard supports
remapping this memory with 64 bit you can use the whole 4GB. Otherwise
you're limited to 3.2:
