Hi DaveJoBot,

 

You might have to upgrade the bios to support the 64bit cpu.

The Coreduo will give you 64bit support but I would agree about motherboard compatibility with your new CPU

Which specific models of CPU - ensure they use the same socket.

FWIW:  The architecture of both systems mentioned...is 64-bit.  It's the O/S (XP) which is 32-bit.  Most systems since P4s are 64-bit.

Actually Louis, the Core processors, that derived from the Pentium M and preceded the Core 2 series, were 32 bit only. I used this one for a quiet music PC:

It used Socket 479 rather than Socket 478.

Hmmm...my sources indicated the P4 were the initial consumer-level use of 64-bit architecture by Intel for PCs.  I just assumed :that no one bothered with 32-bit chips after 64-bit became the norm.

in either case 64bit is possible and a rather nice upgrade to boot, the coreduo is still a rather nice CPU and would run with linux as I am unsure if more modern versions of windows will work (windows 10 has a big question mark on it, and 7's lifespan isnt going to be around for longer)

the cpu is a core 2 duo, t7600, and i read that the core 2 has 32 and 64 support, well i also read that the 64-bit processors are backwards compatible.

A 64bit CPU can run 32bit programs if this is what you meant by backward compatible. For checking if a CPU is 32bit or 64bit Securable is a nice tool.

It seems likely that CPU can be used in a D820, the model was available with that spec.

 

http://en.community.dell.com/support-forums/laptop/f/3518/t/19482974

 

http://www.cpu-upgrade.com/mb-Dell/Latitude_D820.html

 

Note the suggestion that the D820 has been released with different support chipsets, so it could be worth double-checking the chipset in your laptop is the appropriate spec.

 

Initially, somewhat faster processing would be the only benefit you'd experience. In order to get the best potential result you'd need to install a 64 bit Operating System and more RAM. The current 2GB is the absolute minimum for 64 bit Windows, and means losing the biggest advantage of a 64 bit system, access to more than 4GB of RAM.

 Horses for courses. My main rig, an elderly Compaq business-class desktop PC, is currently using a dual-core Athlon64 X2; but the Puppies that I run on it are almost all 32-bit. Reason? They simply run so much faster than the 64-bit ones (and they're not slow..!) The 32-bitzers, though, aaah.....their feet just don't touch the ground.

 

It's all down to personal choice. Sure, I hear all the time about how 32-bit has reached the end of the road, how 64-bit is so much more secure, blah, blah, blah..... In all the time I've used 32-bit Pups, I've never once been hacked, or had any sort of trouble.

 

It's an individual decision, and it works for me.

Well back then even if you had a 64bit 99% of your programs was still 32bit. It's not a deal breaker. The most performance is going from single core to duo that's where the performance is increased. If the duo will even fit the zif socket.
