gtx 670 sli problems, code 43 on bottem card
As the title states, im getting a code 43 error on the bottem card, with or without sli bridge. I've tried each card separately and swapped the cards around. i can use either card in either slot as long as its installed by itself, with both installed only the top card will display to my monitor. With both cards installed, both power up fine so i dont think its a psu problem, psu is a 1000 watt and mobo is sli ready. ive tried a clean install of drivers and even ccleaner and driversweeper, as well as different drivers with no change. Almost to the point of doing a clean win 7 install! can anyone help me out please. thanks

Have had one of the two since release and just got the other today for sli. I haven't updated the mobo bios, got it back around December 2011. Both are gigabyte gtx 670 2 gb models.
Mobo is a asus p6x58-e pro with i7 920
I see the board supports 3 way SLI so have you tried the 3rd Pci-e 2.0 slot? You are probably using the 2 blue slots but the last white slot will handle x8 and you will not see the difference in 16x8 vs 16x16. You might need a longer SLI bridge but it should work. Depending on how long you have used that motherboard it might be time to replace it.

Yeah I thought about that, the inputs going into the mobo at the bottom keep the card from fitting in the 3rd slot, both slots work fine alone so I don't think it's a faulty slot. Would love any and all input to get this resolved thanks. Worst case I'll sell these and just order a 780.
Not only Win 7 issue but also in Win Vista-64 gave the same error code for me. You did "clean" install Win 7 but again you installed new driver from nvidia. Which means that it's a trick of the latest drivers from Nvidia company to force to by new card. Have you tried the manufacturer's driver(Asus,MSI,EVGA,Gigabyte...) or an older nvidia driver(314.07)?
You'll probably first you have to do flash bios of card because it integrates with driver!
Finally, I checked in with an old driver version 258.96 (with old installation wizard) and does not display CODE 43 in Device Manager with low-res desktop. But now its does artifacting on desktop! I try with the thermal compound (the recommendation to take the heatsink of the card, remove any remains of old thermal paste and clean the GPU and heatsink contacts properly and apply a fresh layer of thermal paste). I conclude from this that the new versions of drivers are with the built-in diagnostics for health of card and any type of error happens it reports CODE 43 to stop the operation of the device. I think this is generally in response to all of the same problem-HARDWARE MALFUNCTION:sarcastic:
