Theres is how it looks like ...




Remember, i just install a fresh windows, reflash both GPU bios, retested both GPU alone and stable, resteted the second PCIe slot im using, reinstalled Nvidia driver. Nothing to do ... NO SLI ... damn ******* ****.
Uninstall all the devices with yellow error warning in Device manager, right click, select "uninstall". Then Unsinstall Forceware, restart PC and re-install.

If that doesn't work, remove CMOS battery out for few hours to reset CMOS. Don't forget to unplug power cord while doing this. Then try again.

The only error 43 I've had was caused my by my gpu (9800 GT) over heating *due to no heat sink *.

The card basically died. I was able to fix it by baking it with the computer (keeping it plugged in without a HSF).

Do they both work as singles?

Do both PCIe slots work?

This is driving me crazy .... Both card work alone and both PCIe slot work alone.

Reset Cmos, Reinstalled windows, reinstalled drivers, tryed older WHQL driver ... and still no SLI. Its the same damn thing in the device manager .... *** ...

Is there "revision" of the GTX570 DCII ? I made one backup, and edited and flashed both with the same BIOS. All DCII are the same .... Or not ? Or one card "crapped" cause of the Flash ...

Ill made some test with a friend, he have 2 GTX460, will try if his SLI work in my system. If yes, my DCII are faulty ...

Not if they work alone though, right?

Seems really odd.

@OP sorry I didn't see where you said you had tried that

I have 5 different bridge, tryed 2, ( were working before flahs ... )

And Yes card work seperatly. I can OC and bench each card with 1.2v perfectly...

reinstalled both, no SLI.
reinstaller driver, no SLI
Reflashed to stock volts, no SLI
reinstalled windows/driver, no SLI
Flashed Mobo bios, removed Cmos battery for more than 1hrs and unplug cord, no SLI
System was off and waiting all night, no magic SLI again


This is very weird. Ill try them alone again when i have time. I work for 12hrs today.

Sorry to hear that, it could be the motherboard issue. What you could do is to drain the CMOS by removing the battery, hopefully it would reset. There's nothing much we could do other than when it comes to motherboard.

I doubt this. I think that he messed something up when he flashed the GPUs'. OP, try RMAing the cards. Maybe you'll luck out and they'll send you some new ones.
