I doubt there is any way to get around this issue, but it might be possible on a 64-bit OS, maybe.
Windows 2K, XP PRO (32-bit), and Vista (32-bit) will limit the amount program memory available to an application, even when you have 3-Gb of physical memory installed. Window XP PRO (64-bit) & Vista Ultimate (64-bit install) will access all the physical memory, but then if the installed application limits the size of its memory model you might be limited by the application.
A different approach might be to create a first pass screening process were you remove symbols from the testing symbol list for easy to screen rules like, volume is too low, not enough data, etc.
By generating a screening process that creates a testing list of symbols you should be able to reduce the size you are attempting to work with to something possible for the installed abilities of the computer. Another advantage a screened testing list offers is the ability to just test on symbols that have some hope of being included in a trading program, instead of trying to work with segregate symbols lumped into linear sequenced sized-chunks, and then manually attempt to make decisions after the computer stops running its test on each lump of data.
