Is my cpu 64bit?

[schnipps]

I havent a clue and cant seem to find the answer but i have a intel Duo 2.8, its not a conroe but the one before it, can i use 64 bit windows with it?

I'm guessing you have an intel core duo

I dont think you can:

http://en.wikipedia.org/wiki/Intel_Core

EM64T (Intel's version of AMD64) is not supported by Yonah. However, EM64T support is integrated in Yonah's successor, the mobile version of Core 2, code-named Merom.

Give CPU-Z a try, it should list the extensions/features your CPU has as well as giving you more info on exactly what it is: http://www.cpuid.com

Intel Duo 2.8? I think someone is confused.

Core Duo's 32bit, but its top speed (not overclocked) is 2.33Ghz
Core 2 Duo is 64bit, but it doesnt come in a 2.8Ghz. It does come as 2.67 or 2.93 yes, but not 2.8

Im guessing its a Pentium D 820, or 920, these are Dual Core P4's and support EM64T.

CPU-Z would be a great idea to wash away the confusion.

I didnt know what speeds they run at.....i jus know core duo came before core 2 duo.....and that they dont have 64bit extensions...

Exactly right, his chip supports 32bit, core 2 duo is also 32bit but supports 64 bit extensions

However, if he means "duo" to mean dual core than it's possible it's a Pentium D 820 which does support the EM64T instruction set.

Thats what it is an 820, i havent ran the cpu program as i thought someone would just know, im not desperate to know though cheers anyway.

They're just trying to establish what CPU you have, it helps

The 820 is 64 bit yeah.
