SLI 1080 - Error Code 43

Projeqts · 3 Sep 2016 at 14:27

Hey guys.

I finished building my new rig last night, and it all went smooth apart from the second 1080 in my build is running the Error Code 43 in Device Manager. None of the EVGA software or Corsair Link is picking up the second card.

I've updated BIOs on the Motherboard, I've tried installing a few different drivers from EVGA, but had no luck.

Help appreciated

Can you please post full system specs?

Have you tried running the second card on it's own to rule out that it's not DOA & I am assuming your sli bridge is connected properly as well as the power

z170-A
i7 6700k
1080 EVGA FTW x2
h100i v2
16GB Vengeance DDR4
CX 750 Modular.

Not running any overclocks on either the GP or CPU.

I will swap the cards over in a second and let you know.

Error 43 is no drivers installed or driver cannot start

Just put the card that was playing up in to the PCI 1 slot and it ran fine.

Put the second card that was originally working fine into Slot 2 and it now has Error Code 43.

Sounds like you either don't have drivers installed or something is clashing with them.

Are you running Windows 10 by any chance ?

that folder is nowhere to be seen.

Have you got hidden files and folders enabled?

Just had another look, still nothing.

Spent hours today trying to find an answer but got nothing so far!

What's your motherboard and what slots are you using?

Projeqts · 3 Sep 2016 at 19:08

ASUS Z170-A.

I upgraded to the latest BIOS earlier on with no luck.

Also, I forgot to mention that the second card doesn't have the 8 pins in both sides of the power slot, it has an 8 pin and then a 6 pin on the other slot. It powers up with no problems so this can't be the root cause?

You need to try with both 8 pins connected, even if you use an Molex to 8 pin converter as an temporary solution.

I assumed because the LED's were booting up it was ok. I'll post back the results tomorrow. Thanks guys.
