If you have "DUAL" quad Proc's then why would you see more then TWO.:)
It just means you have 4 "CORES" -PER- processor. Think of the "Cores" as 4 "mini" processors in each individual processor. Does your Mac OS show more then 2 processors when you go to "About This Mac"/"More Info"?
The ram is not "assigned" a processor, it's used by ALL the programs in a "as needed" basis. If your still only seeing 2 gigs+- of ram then it looks like you'll need 64_bit. I only have XP, but I know Windows 7 64_bit shows all your Ram.
You might ask Microsoft if they have an Upgrade system from 32 to 64_bit.
Or, use another HD with 2 partitions and use both for compatibility issues.
64_bit (or 32_bit) only refers to the "basic" Operating System. Windows 7 Home, Pro, etc, just adds more "features" as you go up.
Be aware though, you will need to find out what devices/applications need to have 64_bit drivers.
(For anyone looking at Home, you will have to pay another $100 above the Home version to get Pro for the "XP Compatibility Mode".)
Hope this helps....
Thanks for your help. From a little research it looks like I do everything from the Boot Camp Utility. Remove the Win partition and start over with Boot Camp, then install the 64 bit version. The only programs I want to run in Windows is Sony Vegas and Lumapix FotoFusion, both are 64 bit so it looks like Home will work.
DON'T get the Home version !!
Home versions of WIndows (XP, Vista, WIndows 7) only support ONE physical processor with multiple cores.
Only the PRO versions and above support TWO physical processors with multiple cores each.
With your now installed 32-bit Windows 7 Pro you should see eight bars (= eight cores) when using the Activity Monitor from within the Task-Manager.
1.9GB is a 'feature' of EFI-32
With later models like 2009 (dual 4-core) that have EFI-64 that surprise to me
NEVER ever want 32-bit OS today. Ever.
Home Premium for single socket, Pro for dual, and Pro for more than 16GB RAM. 8GB is actually pretty light for a workstation today for most any type of use.
Two 4 core processors = 8 cores, and that is what the 64 bit version will see, 32 bit versions can only use 2 of the 8 cores.
PCs with multi-core processors:
Windows 7 was designed to work with today's multi-core processors. All 32-bit versions of Windows 7 can support up to 32 processor cores, while 64‑bit versions can support up to 256 processor cores.
PCs with multiple processors (CPUs):
Commercial servers, workstations, and other high-end PCs may have more than one physical processor. Windows 7 Professional, Enterprise, and Ultimate allow for two physical processors, providing the best performance on these computers. Windows 7 Starter, Home Basic, and Home Premium will recognize only one physical processor.
