4GB on ST20G5

I bought the ST knowing its limitiation to 2GB of RAM max.

Is there ANYTHING I can do to update the system: BIOS, motherboard, move jumpers, rearrange switches, etc. to get in a larger amount of RAM.

In case you're wondering, I need this for some of the mathematical modeling I do.

Thanks!

I don't have any proper suggestions I'm afraid, but as it's an AMD S939 motherboard, the memory controller's on the CPU, so I can't see why this would pose any more of a challenge then any other motherboard with only 2 physical RAM slots.
Having said that, I'm not sure what the practicalities are of using 2gig sticks are, and be prepared for a fairly hefty price if you do find this to be a viable method.
