Fail to retrieve Physical CPU count

Hi,

We  encounterer a lot of problems when we want to list the number of Physical CPU of our machines.

My search is based on these fields : Inventory > Processor > « Processor Count » and Inventory > Processor > Features > Cores per Package

I've notice that there's a lot of error when Hyper Threading is activated.

For Example :

Os : Microsoft Windows   Server 2008 R2 Server Enterprise Edition (full installation), 64-bit

Processor : Intel(R) Xeon(R)   CPU           E5630  @ 2.53GHz

Processor Count value : 16

Cores per Package : 16

Hyper-Threading : Yes

Get-WmiObject win32_computersystem | select NumberOfProcessors : 2 ( This is the good value )

This error is present on a lot of our server.

Could you tell me why the processor count has this value and where can I find the true value of the number of physical CPU ?

Thanks
