Hello everybody. Long time no see.

Can somebody please help me find out why I am unable to use the full potential of my Core 2 Quad 6600 2.4 ghz core? I came to find out that after I installed CoD: Black Ops on my computer it doesn't want to load up correctly because it apparently thinks I have a single core PC. I thought it was a simple fix as I haven't updated/flashed my BIOS since I built my machine about 2 years ago. I emailed my MB manufacturer (XFX) and they told me my motherboard was made after the quad core is able to use it. They nicely gave me a link to the correct .ISO file to burn to CD and flash my BIOS. I flashed/updated my BIOS successfully with the file they told me and still no apparent multi-core functionality. I also tried to go to TASK MANAGER and see if I see 4 graphs under PERFORMANCE tab and nothing, even after clicking off "One Graph per CPU" under VIEW tab and nothing, and also not able to right click a process and have the option of SET AFFINITY. My BIOS correctly identifies my CPU as a "Core 2 Quad 6600 2.4 ghz" under the SYSTEM INFORMATION in BIOS, so why this problem?!

Please somebody help me understand what is the problem and how to fix it. I want my PC to see and use my Quad core... not pay money to still use a single core. Thank you and much appreciated for all help and insights.

My specs on my computer are
CPU: Intel Core 2 Quad 6600 2.4 ghz
Motherboard: XFX 630i 7150
RAM 4 gigs
Video: GeForce GT 430 1 gig

The game has to support multithreading, and if it doesn't it will only use one care of any multicore processors.

Please perform the following, so that we can get the exact specs of your computer. This will better assist us in helping you more.

Here is a screenie of my machine with Speccy. Please somebody help me figure out how to make it recognize and use the 4 cores I have. I am very frustrated at this point.

Look in the device manager under computer. It should say ACPI multiprocessor. If anything else is listed you will need to update the system to ACPI multiprocessor.

OK here is the link. Sorry thought the screenie would be more informative. Hope this helps resolve the problem.

Baltboy... Under Device Manager > Computer - it says "Advanced Configuration and Power Interface (ACPI) PC". But under Processors is lists four lines with the same processor "Intel® Core™ 2 Quad CPU Q6600 @ 2.40 GHz". How do I update the system to ACPI multiprocessor?

I think you have your BIOS configured wrong. You have multicore disabled, and I would check your motherboard manual.

Your clock speed is also wrong.

You will need to go back to the device manager and open the ACPI PC. The choose update driver. It should either present you with a list or you will have to choose to select from a list for the driver. Choose the ACPI Multiprocessor and that should do it. Was the Quad core an upgrade to the original system? This is a common problem when upgrading to a multicore processor the HAL needs to be changed for Windows to properly utilize the CPU.

This machine was built all together about 2 years ago.



Baltboy... I chose "Update Driver" under the ACPI for the Device Manager and chose "Allow Windows Update to connect this time only". It searched and found nothing for update. This machine I built was a first for me that had multicore so, yes I am unfamiliar with the settings for it.

cryptodan... The tech I talked to at XFX for my motherboard said my MB should automatically see and use the Quadcore as it was made after the quadcore came out. Do you think if I change a few settings on the motherboard like clock speed and such it would "see" and use the multicore?

Just talked to the same tech at XFX and I told him what you all were saying about my problem. He noted especially what Baltboy said about the multiACPI. He had me go to Update Driver > No Not This Time > Install from a list or specified location > Don't Search I will choose the driver to install. In that window he said it should have listed Multiprocessor ACPI as a choice and it wasn't there. He then told me to click "Have Disk" and locate the .DLL file called HALMACPI.DLL. We found it but it wouldn't let me click it as an applicable file to use for an update. He then had me locate the HAL.INF file in the INF folder under windows, but even after double clicking that it still didn't add to the list of options Mutliprocessor ACPI. His final solution he said was to do a Windows Repair and then hit F7 somewhere along the process and "force" the HAL insertion. Here is the link.

BIOS's can be configured to disable cores on a multicore processor check your manual for more information.

Look at page in your motherboard manual and look see if Core Multi-Processing is enabled?

Since the multiprocessor option isnt showing up i would tend to agree with cryptodan. XP and newer windows versions will not show you options that your system isnt capable of so you will not crash your PC. Since the only thing that should be blocking the recognition of the quad core would be the hal or the bios and the hal isnt showing it as an option than looking hard at the bios options is the first place to start.

OK I am at the point where I think I am going to be buying a new motherboard to try this out... see if its the motherboard or the chip? My only question is, when I pull all the components out of the computer, install the motherboard, and connect them back to the new board, will any of the components need to be configured to the new board, or will they plug and play and boot up like normal? I am thinking they will boot up like normal. If they boot up like normal and the problem of not recognizing the Quad Core was my old motherboard, will the new motherboard see and use the Quad Core as long as it is Quad Core ready?

Have you checked the Motherboard Manual on the page I referenced by looking up your motherboard on XFX. Please do, and verify that it is enabled. If it is disabled, then your computer will not use all the cores, and is reflected in your speccy.

Problem with getting a new motherboard, will be the fact that you will have to reinstall Windows. Please check the BIOS as referenced in my post above.
