A 64-bit Operating System is required to take advantage of 4GB memory. A 32-bit Operating System only recognizes up to 3GB memory ? Really?
really.

Yes, and more... our hardware will need to handle more, and a lot of old 32 bit software is no longer going to work because of how much is

changed when we go to 64bit architecture.

he wil be sticking with 32 bit for now then, as much of his software will not function via 64bit OS.
I'll stick with my Mac Classic.
...it's got a *grayscale* monitor!
grayscale! wow. so you have ... all the colors of grey? that must be soothing on the eyes.

no clue but thinks it is all good...

technically that's not true, a 32-bit OS can support greater than 3 GB but not contiguously meaning that it could page it.
AZJazzyJ
says
Win XP and Vista will show only 3 GB usable memory but the OS itself will use the excess for internal calculations and paging.
AZJazzyJ
says
I know it's true for Vista based on testing I've done although it is not well documented.
learns something new every day (or night) here at Plurk... I'll have to keep that in mind AZJazzyJ. Is that only true in Vista 32bit then?
AZJazzyJ
says
I've verified this is true in Vista, I haven't tested it under XP (yet). You are still better off with a 64-bit OS for apps to use memory.

technically 32 bits could address 4.29 x 10^9 (4.29 Gig) of address space. 64 bits could addr 1.84 x 10^19.
AZJazzyJ
thinks
the device drivers for a 64-bit Microsoft OS are now to a point where the stability is on par with the 32-bit drivers.
