Windows 7: Windows 7 Professional 64bit & TWO physical core duos (4 processors)

Windows 7 Professional - 64 bit
 
 
Windows 7 Professional 64bit & TWO physical core duos (4 processors)

I have a HP Pavilion a6767c. It is a 64 bit machine. It has TWO Core Duo ES300's at 2.6 Ghz. (TWO physical core duo processors with TWO cores each equals 4 processors total available). I am running 64 bit Windows 7 Professional.

My question: Other forums say that Windows 7 Professional will support multiple cores. When I ctl-alt-del the performance monitor shows only two graphs.

Does this mean that Windows 7 Professional is only using the two cores of one of the two physical core duo processors and ignoring the other two cores on the second physical core duo processor?

How do I get Windows 7 to recognize all 4 cores and show me 4 graphs in the performance monitor?

I bought the box for Autocad and I want maximum performance.

Thanks for any light anyone can shine on this question.

Thought this post looked familiar. (vistax64). Duo core and dual cores are different. See here. Intel® Core™ Duo Processor — Frequently asked questions for Intel® Core™ Duo Processors

duo core mounted (IMO) on one chip, dual cores mounted on separate chips on different sockets.

IN either case you have task manager showing one graph per cpu (1 x 2=2) and that is correct, Your computer is using both cores per cpu under load.

No it doesn't. And it is an E5300, not ES300.

and the motherboard in the above HP,

One physical socket for one physical CPU, with 2 cores in the CPU.

You don't seeing as it is working properly and you don't have 4 cores.
