hello,
how to know the speed of my CPU 32-bit or 64-bit.
My CPU: Intel Pentium 4 531, 3000 MHz.

More about : cpu 32bits bits

Hi newcomer and welcome to the Tom's hardware forum.

Easy answer: Don't support x64 OS.

You just missed.....the first Intel 64 bit chips were the Pentium 4 6xx series. If you had a 631 it would be 64 bit.

I doubt the board supports enough memory for it to matter. 4 Gb is the best reason for 64 bit OS.

Although this thread is old, I thought I would put my two cence in any way just in case any one want's to know about this particular information.
>The Intel P4 (Prescott) CPU 531 that you have is a 64-bit CPU, the 530 and 530(J) are both 32 bit CPU's, so yes you can install a 64-bit Operating System with the CPU that you have. All three of these support HTT which gives them a 15-30% performance increase as long as you have a Motherboard that supports HTT.

Here is a link to the correct information on your CPU 531, the 530 and the 530(J) : http://ark.intel.com/Compare.aspx?ids=27465,27464,27463,

Agreed with Huge.

The instruction set is 64-bit, so it should be able to handle a 64-bit OS. The speed isn't affected by 32-bit or 64-bit support.

Correct, speed has nothing to do with the instruction set. I forgot to mension the speed thing, silly me, thanks for clearing that up for every one Haserath.
