yeah, your board has a few different settings to mess with regarding memory latency. they're under "advanced chipset features" in your bios. set "memory timing" to user defined. then you can set "sdram active to precharge delay", "sdram ras to cas delay", "sdram ras precharge delay" and "sdram cas latency" (CL) to lower numbers.
if your pc3200 is running at 266mhz, you might be able to set those four variables all to '2'. that's what i've done with mine as you can see in my sig. otherwise, maybe 4-3-3-2 or something. experiment.
