I have a Dell Optiplex 320 with an Intel Pentium D and in the Bios it's got SpeedStep disabled (what does this speedstep do?) and it's got an option for 64 bit. Can I enable it since I'd like to use a 64Bit application with my current version of windows? XP PRO

Sorry I don't have the option to enable 64 bit processing, it says in the bios 64-bit capable ------ yes. To take advantage of that, I have to install XP 64 bit and that's it, nothing else?

Speedstep is a built-in application for Intel processors to vary the wattage usage. If you're loading the cpu,(processor), down with a game lets say, the wattage usage goes up,(heat values also), but at idle the cpu doesn't need the full wattage requirement, so the voltage is 'stepped down' inside the processor. WinXP Home, and Pro have this feature built in, and do not need the motherboard's BIOS to enable it. There are 32bit WinXP Pro OSes, and 64bit WinXP OSes, you cannot make a 32bit OS into a 64bit by flipping a 'switch' inside BIOS. This is a whole different program,(64bit). This feature is in your version of BIOS so that should you install a 64bit Operating System, you can enable BIOS to recognize it.

Speedstep is very useful for prolonging battery life in laptops. It simply downclocks and undervolts the processor to reduce power consumption.
64 bit OS is best for servers. If you want your device drivers nightmare to begin, go ahead and try 64 bit OS.

XP will support speedstep, unless you have XP 64bit OS, you cant use 64bit applications.
