Hi,

a 64 bit mathematica ma be an option, the Grid version with
the distributed memory parallel processing would need more
memory.

But you can try
a) $HistoryLength=0;
b) avoid the display of the data
c) on my computer with 3 GByte Ram and Winows Vista 32

mat = Table[Random[], {3500}, {3500}];
tmat = Transpose[mat];
res = tmat.mat;

work fine and

MemoryInUse[] gives
299732472
and
MaxMemoryUsed[]
gives
300861864

Regards
   Jens
