Hello, I am just wondering, how can I find out if my processor is using a 86 or 64 bit. I tried going to device manager and clicking on processor and then properties. But couldn't see any details whether my computer was running a 86 or a 64 bit. Many thanks, Steve

What's the model / manufacturer of the CPU? And the question is, "Do you have a 32-bit processor or a 64-bit processor?" There is no 86-bit processor, and most PC CPU's have the x86 instruction set, regardless.

Core Duo = 32-bit Core 2 Duo = 64-bit The T2050 is a Core Duo, so you've got a 32-bit processor. Pentium III--Descendant of Intel Core. Pentium III-S 1400 @ 1.63GHz, 512K L2 X800XT AIW OC 580/600 2GB of RAM 250GB HD SB Audigy 2 QDI Advance 12 mobo Smugly running Vista

Hello, Thanks for your response, I was just wondering how you could find out on your computer. Thanks, Steve

To have your computer tell you in its own words the capabilities of your processor, download CPU-Z. http://www.cpuid.com/cpuz.php If CPU-Z lists "EM64T" in the Instructions field, then you've got a 64-bit processor. However, it won't since you've got a Core Duo, which is a 32-bit CPU. Pentium III--Descendant of Intel Core.

Centrino has never been the name for a CPU but a mobile platform technology that includes specific CPU, chipset & wireless network adapter as a unit combo. Your Pavilion dv6000 CPU is actually an Intel Core Duo T2050 with Centrino Duo Mobile Technology. Unfortunately it is NOT a 64-bit processor, but a 32-bit 1.6GHz Yonah CPU with a 533MHz FSB. http://support.intel.com/support/no... http://en.wikipedia.org/wiki/List_o... PS. If you prefer to check for this detail on the system rather than going by the CPUs specification, you can simply navigate the registry through, HKEY_LOCAL_MACHINE\HARDWARE\DESCRIPTION\System\CentralProcessor\0 Then look at the right pane under ProcessorNameString & Identifier & you should be able to very the CPU platform.

I have a the Q6600 quad core (64 bit capable) and the registry lists it as a X86 system (32 bits).... I am running XP 32bit right now. If you want to know your processor... then download Everest Home Edition and run it.... it will tell you all you ever wanted to know about your machine.
