What do you think would give the fastest depth overall? More hash or Large Pages?
If I am not going to run Large Pages I might as well set the hash to 4096 for both engines in this match.
What counts most is that you can guarantee that all engines are treated identically.
As Windows doesn't give you any control over its adress space fragmentation, you probably will have to run multi-engine tournaments without Large Pages. In that case a 4096 MB ordinary hash would be very nice 8-).

Robert, I've enabled so that engines can use up to 4 GB of hash.


In other news, TCEC Tournament 4 is over, with Ivanhoe winning by S-B tiebreaks over Rybka 4.
The next event, R4 vs the latest Ivanhoe should start in a few days.
