You could use PC4000 DDR(1) modules, either running at
PC3200 speed or at higher speed if your board supports it
and is stable doing so. Typically only an aggressive
overclocker would do so.

DDR2 won't work in your board. Won't fit, because it
wouldn't work if it did fit.

The best performance is typically running at same clock rate
as FSB, or in some cases the +33 async mode, and the lowest
timings the modules and board support. So if your CPU and
board dictate PC3200 memory speed, get modules with 2,2,2,5
timings... though just because the module supports these
timings, it doesn't necessarily mean the board would be
stable, and shouldn't use them anyway if you also have other
modules with slower timings installed simultaneously.
