Can I see SpeedStep and 64-bit processing?

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

Can I see SpeedStep and 64-bit processing?

Speedstep is a built-in application for Intel processors to vary the wattage usage. If you're loading the cpu,(processor), down beside a game let say, the wattage usage go up,(heat values also), but at idle the cpu doesn't want the full wattage requirement, so the voltage is 'stepped down' inside the processor. WinXP Home, and Pro have this element built in, and do not want the motherboard's BIOS to enable it. There are 32bit WinXP Pro OSes, and 64bit WinXP OSes, you cannot breed a 32bit OS into a 64bit by flipping a 'switch' inside BIOS. This is a whole different program,(64bit). This phase is in your performance of BIOS so that should you install a 64bit Operating System, you can enable BIOS to authorize it.
XP will support speedstep, unless you have XP 64bit OS, you cant use 64bit applications.
Speedstep is markedly useful for prolonging battery-operated life contained by 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 initiate, go ahead and try 64 bit OS.
