Another potential advantage is the large address space. With terabytes of ram directly addressable, potentially totally new solution ideas may be formulated. For instance, you could memory map the 3-4-5 man tablebase files and lose the disk access penalty. That might make them give a large Elo boost, while the disk access method for 32 bit systems seems to be about break even. You could have 20 GB hash tables. You could store (in ram) a large tree of every chess game ever played together with statistical information on each node.
