You need 5 posts to download it.

-i - Force a specific device index.-5 - Allow firmware and adapter PCI device ID mismatch. -6 - Allow firmware and adapter PCI subsystem ID mismatch That should be the problem. - - - Updated - - - How are your temps with the 1050mV BIOS?Do you notice a big difference at the same clock?

I used this procedure:Backup (Dump) Primary GPU:nvflash -b backup0.rom[RIGHT]Backup (Dump) Secondary GPU:[/RIGHT]nvflash -b backup1.rom[RIGHT]Flash Primary GPU:[/RIGHT]nvflash -i0 -5 -6 FILENAME.ROM[RIGHT]Flash Secondary GPU:[/RIGHT] nvflash -i1 -5 -6 FILENAME.ROMBoth Windows and DOS version have the same commands. On windows you have to run cmd as administrator.

There is definitely something wrong. Your idle temps should be around 50C.Check your heatsink, maybe the contact with your cpu is not optimal.

I have the same laptop with 680m SLI.With stock BIOS I had a +135MHz limit while overclocking. Now I use the stock voltage modded version, and the limit is gone. What program are you using to overclock?

Dell GPU: 680m SLI vBIOS: stock voltage Core/Memory Clock: 920/2250 3d Mark 11: 12489 (windows 8) 3d Mark 11 GPU score: 15039 3d Mark Vantage: not tested CPU is a 3740qm with 41/40/39/39 Edit: just added GPU score

Wow, best thread ever I'm downloading the dell 1050mV version, and then I'll procede with overclocking. I think I will start with a "safe" 900/2200. Can this card get stable 2400 memory clock? Special thanks to svl7, awesome job here.
