My C2D processor only showing one Core!! Please Help!!

Nour Ershaid · 05-08-2007, 06:41 AM

Iv bought a new pc :

CPU : Core 2 Due E6300 1.866 Ghz
Motherboard : MSI RC410M2 PCI-E
Ram : 1 GB
Hardisk : Sata Western Digital 250 gb
Video Card : GeForce 7300 LE PCI-E 512 Mb

everything was fine until i reformated the windows and ,, the main problem is that diagnostic programs such as everest dont show that my processor is Core 2 Due ((E6300)). they were showing that my pc is core 2 due untill i formated the windows !! i formated again but it is still showing that processor is 1 core !!

can u help me please?

my bet is that you are running Windows XP Home Edition pre-SP2. XP Home doesn't recognise more than one processor unless SP2 is installed.

im sorry to tell you im running on Windows XP Pro SP2

look at this picture please :

watch that CPU-Z say my processor has one core in the bottom

there are a few other possibilities involving ACPI drivers but i don't know much about that.

Hello,

In Windows XP, go to run and type msconfig. Hit enter.

When the msconfig windows appears, click on the boot tab, then click on the Advanced options... button. When the Advanced options window appears, check the Detect HAL box, the ok and apply all dialogues.

Restart your PC, and check to see if both cores are active either in task manager or CPU-Z.

Sorry. Thought the same applied to XP.

Nour Ershaid · 05-08-2007, 12:08 PM

thanks for trying to help anyway

Hello,

Check in your BIOS to see if you can enable / disable dual core functionality.

If no option is available, then in Windows XP device manager, try changing the ACPI driver.
