View Full Version : Computers Is there an easy way to tell if a Pentium 4 is 64 bit?

I am looking at buying a used/refurbished computer to use as a htpc and there are a lot of P4's available but I want to load Windows 7 Home Premium (64 bit). According to wikepedia the P4 chip was manufactured from 2000-2008 and in 2004 they started to include the 64 bit in the chip. Any ideas or should I just buy a pc with a more recent chip? And before I get a bunch of you don't want to do that replies I am trying to build this thing for less than $250.

I'm pretty sure the Cedar Mill core P4s were the only ones that fully supported 64-bit. Those would include the Pentium 4 631, 641, 651 and 661 models.

Do you only have a 64-bit version of the OS or something? Cause if you're trying to stay under $250, the difference in 32-bit and 64-bit won't matter.

I looked it up, and there were a couple Prescott models that supported 64-bit too.

Models 506 and 516 should be 64-bit capable too.

Thanks for the info. I think I am just going to replace my desktop pc and use it as my htpc. I can buy some pretty good refurbs for about $300 and my current desktop has a core 2 duo.

Just FYI I'm not making a full blown htpc. The only feature I will be using is the streaming Media from my main pc to my tv using a VGA and Audio cable.

I have windows 7(x64) on my desktop and laptop and I love it.

wouldn't any of the HT models support 64bit?
