I have a Dell Dimension 2400 desktop PC. I can add up to 2 GB of RAM but I am getting conflicting info on what type of RAM this computer uses. I know it is DDR SDRAM, DIMM 184 pin, non ECC, unbuffered, but I need to know if it uses PC3200, PC2700 or PC2100. The only thing I know about this computer are the followig specs:

Intel Celeron 2.40 GHz proc

2.39 GHz, 512 RAM, 37.2 GB Hard drive.
