Did some research, but cannot vouch for it. Win 7 HP can utilize only one processor. But 64 bit, like mine can use more.

Also check your MOBO Bios to ensure that all is configured correctly.

In Intel's I think hyperthreading needs to be enabled (hyper something anyway), sorry I cant be more helpful. Perhaps just resetting it to the defaults will help.

Windows 7 Home Premium only supports a single physical socket. As far as I know, there is no practical limit to the number of CPU cores within that one socketed CPU.

Win7 Pro and Ultimate support 2 sockets.

I believe there's no difference between the 32 and 64 bit versions as regards htese limits.

I can't explain why you're not seeing all 4 cores. It's not due to a fundamental Win7 limitation, though. (Win7 Home Premium 32 bit sees both cores of the AMD CPU in my notebook, for example.)

I think this is a fairy tale. My win7 runs on both of my duo core processors. I think the guy that said that in the thread you linked is wrong.

PS: I did read your whole post - I even quoted the whole post. No problem.

I had a thought, if you can get into bios, there might be a setting for max cpu or max ram. If it is checked uncheck it.

Before you do anything like this, I suggest a System Image.
