AGP Card Code 12 in Device Manager

Posted on 2007-07-24
Last Modified: 2013-11-09
Hi Techs,

I have problem with an MSI 865G/GVM3-V Motherboard.  Whenever we install an AGP video card it will not run.  Device manager detects the card but gives it code 12 - there are not enough resources for this device to run.

This happens under XP and Vista.

We have uninstalled all existing Video drivers, disabled onboard video, disabled all non-essential devices (COM, LPT, Audio etc) but still get code 12.  We have tried different AGP Aperture options in the BIOS as well.

We have tested with an 256MB Inno3D 7600GS and a Leadtek 128MB Quadro4 750XGL AGP cards.

If anyone has come across this before and has any suggestions or solutions it would be greatly appreciated.

    I would advise you to read the information provided by Microsoft on the "code 12" issue: . I would then try to track down the device that conflicts with the video cards, and try to change its resource settings (in BIOS if possible, otherwise in device manager in Windows). Using the different view modes in device manager can help you out in determining which resources that seem to be lacking or shared with too many devices (DMA / IO / IRQ / Memory).

    I hope this helps.

    When viewing resources by connection the only device I can see that might be causing a conflict is the Intel(R) 82865G/PE/P/GV/82848P Processor to AGP Controller - 2571

    I assume this is needed for  the AGP port to work in the first place.  If I disable it it disables the video card as well.

    Any suggestions

    probably a mobo problem; if still warranty, return it

    The same thing happens on 2 of the exact same motherboards - could it be a compatability issue? I can understand that with the 7600GS but not the Quadro4

    I'm not 100% what would correct this problem, but there are a few things I would try if this happened to me:
     - Update the BIOS & load the default optimized settings
     - Disable any integrated video adapters in the BIOS (I see you already have done that, but remember to do it again after reverting to default settings)
     - Update chipset drivers (assuming you already have the latest video drivers, as you mentioned in your question)
     - Check that the motherboard in fact supports your graphics card's AGP architecture (if it's a 4x card, your motherboard should support 4x aswell)

    Problem solved.

    The motherboard PCB was version 2 which required BIOS version 5 to be installed (Version 1 was installed).  This version BIOS was not available on the MSI website which is why I was under the impression that the MOBO had teh lates BIOS installed.  After called MSI and convincing them that I neede the version 5 BIOS they emailed it to me.  After BIOS updated all graphics card install fine - NO CODE 12.
