Hi people,
Is there an OS built-in limit on the number of CPU's and/or cores that Windows 7 Home Premium will support?
I know there was a memory limit but I also believe that was removed. Was there ever a CPU/Core limit and is that still in place?
If anyone has a link to backup that would be great :)

The link I have is this:

http://windows.microsoft.com/en-US/windows7/products/system-requirements

I'm just not sure how up to date it is and if there have been any changes that might not be reflected in this link. It says:

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.

So fully agree on the actual core side of things - 64bit supports 256 processor cores.
But the bit at the bottom says that 7 Starter, HB & HP only support 1 physical CPU. So if someone was for example running a machine with 4 physical CPU's (all quad cores) they would not be able to see the full benefit from Windows 7 - with the lower end versions only supporting the 1 physical processor.

Just want to make sure this is still the case or if there is anything that has superseded.
 
i very much doubt anything has changed. these limitations have been with us since window XP (maybe even 2k but i can't remember). 1 socket for home editions and 2 for pro/ultimate/enterprise/whatever.

you'll be wanting a server OS or switch to linux.

Cheers. It wasn't for me - although I wasn't aware of the limitations, hence me asking in the first place :)
Just a discussion on different forums about a certain PC and it's performance in games.
I'll pass on what I've now discovered.
