Windows 7 - Dual Core Xeon 3.6Ghz Processors

Hello all..

Have a quick ? for you all...

I have installed Windows 7 on my IBM Intellistation machine which has 2 Intel 3.6Ghz Dual Core Xeon Processors. Here's my question...

In Device Mangler, it shows Processors>Intel(R) Xeon(TM) CPU 3.60Ghz x 4. When I check Task Manager, it shows me the utilization of two processors.

Is this correct!? Should TM show 4 boxes instead of two!? Or is Windows 7 seeing everything okay?!

Thanks in advance!

Which version of Windows 7 do you have?

It's not easy to find the information, but apparently you need Professional or Ultimate to use two physical sockets. Home Premium only supports one.

I forgot to include that.. My apologies...

I have Windows 7 Home Premium x64.

AND...

Am I REALLY going to benefit from upgrading from Home Premium to Professional in order to utilize the processors!?

Physically there are 2 processors (cores). However if "hyperthreading" is enabled then these 2 may sometimes show up as 4.
I see the difference on my machine (running Ubuntu) when enabling/disabling hyperthreading.
Hyperthreading is enabled / disabled in the computer's BIOS

You cannot take advantage of 2 physical CPU chips with Home Premium. You have to be on Professional, Enterprise or Ultimate to utilize both physical CPU's.
