Graphics card: eVGA Nvidia Geforce 8800GTS 640 MB (factory OC'd version)
Motherboard: ASUS A8N SLI

This seems to be a common problem, but my link width is set at 1x and I cannot, for the life of me, figure out how to set it back to 16x. I've tried increasing the PCIE speed to 101, 102, 103, 104 and 105 MHz, and it's still the same. Flashed the bios to the latest version, set everything to default... still the same.

Upgraded to the latest stable nvidia drivers, and the link width is still at 1x.

CPU-Z


Nvidia Control Panel (Not sure if this is important or not)


I've checked many times in my BIOS for some option to change the link width... and I can't seem to find anything. Is there any other way to fix the link width?
 
Is it just what you're seeing in cpuz and NCP or are you actually having performance problems?
 
well, it doesn't seem to be affecting my overall performance, however, i get scores around 3300 in 3dmark06, and I *know* I should be getting higher scores than that.
 
some more info about my hardware:

CPU: AMD Athlon X2 4800+ @ 2.64 GHz
Memory: 4 x 512 Corsair XMS DDR 400

So yea. I *do* have it in the sli card slot (meaning the second pci-e slot) but I cannot simply move it to the other one, since it won't fit (chipset heatsink is in the way.)

Regardless, I should theoretically be able to get 8x link width...
 
My setup is in my sig. I found through a bit of digging through forums and more forums, that a solution may be as simple as increasing the voltage to your north bridge. I know it seems funny to do so, but I found other people with my setup and overclocking over 400 fsb, the mobo wants to lock the pci-e slot to 1x. I know you dont have a p5b, but try increasing your northbridge frequency a bit and set your pci clock frequency to 101. Let me know if it works!

My bios doesn't allow me to alter the voltage to my northbridge :/

I'm currently using a built-in overclocking feature available on the A8N-SLI, "AI Overclock +10%"
 
So no go on the voltage uppage... well, if you want your graphics card running at the full 16 lanes, I would probably turn of the auto overclocking feature and then checking to see if that did that trick. Then you can know if that was what was causing the pci-e lock. If that doesn't do it, then try something else, and keep going until you find out what's causing it. I'd put my money on the auto oc. Good luck!
