SLI nVIDIA Geforce 8800GT code 12

[eren]

i have windows xp MCE & i recntly upgraded my cards to 8800 gt for 2 pcs but the second card has a bang in device manager?

So what i did was :

1. First i uninstall/reinstalled nVidia driver (latest from nvidia website)
2. Then i disable/enable SLI
3. Later i reseated both vidcards
4. After that i swapped PCIe ports on both vidcards.
5. Lastly i reseated/removed SLI bridge

The bang always appears when the 8800 gt card are used individually. Is this a SP3 fualt or driver related. Also i got an error code in the device manager like (it is something like this device cannot be use - device already in use - not enough free space you have to disable another device Code 12). So if anyone can help me out with this would be great

Here is the meaning of Code 12

Code 12

This device cannot find enough free resources that it can use. If you want to use this device, you will need to disable one of the other devices on this system. (Code 12)

Recommended resolution

Two devices have been assigned the same I/O ports, the same interrupt, or the same Direct Memory Access channel (either by the BIOS, the operating system, or a combination of the two). This error message can also appear if the BIOS did not allocate enough resources to the device (for example, if a universal serial bus (USB) controller is not an interrupt from the BIOS because of a corrupted Multiprocessor System (MPS) table).

You can use Device Manager to determine where the conflict is and disable the conflicting device. On the General Properties tab of the device, click Troubleshoot to start the Troubleshooting Wizard.

Thanks AdamT, will give it a shot

I think its shortage loss of power supply. A good quality with atleast 650 watts would do the trick for you.
