If you have an Intel Dual Core Processor, wouldn't that justify using Ubuntu 64? After all it's 2 32 bit processors in one die.

Actually its 2 64 bit processors on one die. and if you want you can run the amd_64 version of ubuntu on just about any modern cpu, be it an athlon 64, or an intel core based design.

Both of them are 64 bit architectures that can run 32 bit code..Consequently you can run either a 32 bit or 64 bit OS on them.

Hope that helps

No, because each one of the processors can store addresses of 32 bit. They don't work together in such a way as to be able to store 64 bit, each processor half of it. That would kind of make two processors pointless, since the idea is that they can do different tasks parallel, independently of each other.
Having said that, the modern dual core intel processors are 64 bit anyway.

Dual core and 64bit are not the same thing

64bit http://en.wikipedia.org/wiki/64-bit

Oops my mistake...

Intel core solo and duo are 32 bit
pentium dual core are 32 bit

only core 2 duos are 64 bit

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

Either way the poster above is bang on, a cpu is only 64 bit capable if it can address memory by a 64 bit long address, having more than one core is irrelevant.

well with all but one saying I have 64 bit capabilities, how do I upgrade my system to 64 bit as I have it customized the way I want it.

I dont belive you can upgrade from one system to another without wiping things out but having said that, if you are feeling brave, you could try installing the 64bit kernel from the repos and see what happens

make sure you back up *everything* before you try though

Actually. Pentium DualCore is 64bit (got one myself), Core2solo, Core2Duo and Core2Quad are 64bit too, CoreSolo and CoreDuo are the 32bit ones.

You can't upgrade to 64-bit from 32-bit. You have to do a clean install with a 64-bit os.

Always back up before upgrading or doing a clean install. Nothing is guaranteed perfect.

I didn't think you could but figured if possible, that would be the only way.

and I agree, backup before making any changes, heck, backup once in a while anyway cause drives do fail

well I ran the live CD and it worked, so I installed Intrepid Alpha 6 64 bit. Very little conf, it helps to have "home" on a different partition. BTW: it a Pentium "Dual-Core". Thanks for the advise.

Very nice.

I have enjoyed being 64 bit for over a year now.

It really makes a difference when you use it every day.

I was wondering what the difference was between Dual Core and Core 2 Duo. Thanks.

DualCore is from the "old" Pentium family (sixty-something nanometers), while Core2Duo is a new family (45 nanometers).
BTW, the nanometers thing is the size of the conductors within the microprocessor, the smaller it is, the cooler it runs and less power it uses.

And to be completely picky:

32 bits + 32 bits actually = 33 bits. Binary math.
