Most likely not in a 32 bit windows operating system. Since you will
be very limited due to address space fragmentation. Remember with the
default 2GB per process limit (regardless of the ram you have) of 32
bit windows gives you about 1.2 GB maximum single allocation.
However like Michael Jackson said it will work fine if you have a 64
bit executable on a 64 bit OS.
