I have a board I got for free from an old friend and it is a ASUS P4VP0-MX and i have no clue what kinda ram to use it is running with a ddr 266mhz cl.2.5 ram card with 256mb. What I am wondering is if I can use 1GB 184-Pin DDR SDRAM DDR 400 (PC 3200) in the ram slot. so can you go from pc 2100 to pc 3200?
