64-bit Required for Dual Core...?

[Guest Ben]

I have a laptop that came with Vista Ultimate 64 bit. It's a dual core

processor -- and for some reason I thought you had to have a 64-bit OS to

take advantage of multicore systems. Vista has been a bit of a pain, and

I'd rather use XP on it. I have a copy of 32-bit XP Pro -- will the OS take

advantage of the dual-core processor? Thanks!

XP Pro will use both cores, but check that there are XP drivers for all your

laptop devices before you change.

Also, if that laptop have >2 GB of RAM, you may lose some of the available

RAM.

All XP can use both cores. Cores are logical processors and the number of

them on a physical processor is irrelevant. It can be one, two, three, or

four.

 

Dual physical processors are what require Pro since Home can only use one.

The number of cores in each of those two processors does not matter.

No. Anyway, not all multicore processors are 64bit capable. The Intel Core

Duo is a dual core 32bit cpu.

 

32bit editions of Windows run natively on 64bit cpus just fine.

Thanks for the info everyone, very helpful! I've looked into it a little

more and found that I have a Intel Core 2 duo T7200 processor, which is

64-bit capable.

 

Would there be a benefit to sticking with Vista Ultimate 64 and just to a

reformat and reinstalling of it? I'm not sure what the benefits of a 64-bit

OS might be, but after using it for almost a year it just seems overall a

bit sluggish. It could be that starting over with SP1 applied prior to

using it might be better than going with XP Pro 32-bit...?

 

Thanks again for all your help!!!

That's the sort of question that can lead to quite long and, perhaps,

heated replies :-)

 

I have tried very hard not to go the regular install route with Windows

but when I finally give in I always find the machine more responsive. I

even use an XP VM for trying software before I install it on the main

machine so I don't clog the main machine up. I also run NOD32 (64 bit

version) and regularly run cCleaner and Spybot, check the disk regularly

and defrag regularly. Nothing seems to beat a re-install though.

 

What we really need from MSFT is a decent registry cleaner and de-fragger

(I would prefer to dump the registry except for system entries) along with

a proper file manager instead of these silly cut down versions of "Movie

Maker" etc.

 

I suspect a re-install would give you a new lease of life - what I have

done now is a clean re-install, load all he system drivers then activate

and ghost the drive, that should mean a future re-install is a 10 minute

job. I take a second image after all the apps are installed and activated

then replace those over time as new apps are installed. I still have my

base image though.

Thanks... I think this thread has gotten a little diluted -- my fault,

didn't really know what to ask. Thanks for your reply -- I'm going to start

a new thread and try to ask the question more clearly.
