SLI option disappeared, both GPU's detected

post #1 of 5
Thread Starter 
Well after de-assembling my second GTX470 for some loop cleaning I reconnected everything and booted into windows, straight away it detected my second GTX470 and installed the same drivers my 1st GTX470 was using (267.24).
I went into the NVIDIA control panel and couldn't find any SLI options in the PhysX tab(where normally it is)...

Picture attached:

As you can see both GPU's are detected in the NVIDIA control panel as well, I also checked in GPU-Z if SLI is enabled and it stated that it is disabled.

Since then I went into safe mode and did a clean uninstall to the drivers along with driver sweeper, tried rolling back into 266.58 yet it didn't help as well.

Any ideas? :/

Try these:
1) Take out the SLI Bridge and reseat it. Be gentle with it. It is a sensitive little device.
2) Take out each 6-pin PCIe connectors and reinsert them, making sure you have the 'click'
3) Take out the cards and reseat them. This might be a hassle as the cards are under water.

4) As both cards are detected properly (without SLI) , perhaps it is a good time to stress both simultaneously to see if any error comes up.

Reinstall the drivers once both cards are in.

Usually, its a drivers error as it finds the second card, but doesn't realized its SLI-able until you re-install the cards.

I had the same issues when I had my 470s.
When ever I took out the cards and put them back in, if it was not at the exact order, the drivers would go mental and demand a re-install of the drivers to enable SLI again.

Moved the SLI bridge to the right since it looked like it was sitting well and viola everything works smile.gif

Feeling abit silly I didn't have a go before since I was convinced it's a driver issue.

Thanks alot, rep given smile.gif

This. Use driversweeper in safe mode to make sure the driver is completely removed.
