MSI GTX1070 Gaming X SLI Issue

[dementorchemist]

Hi all,
I originally bought one MSI GTX 1070 GAMING X and seriously have had no issues with it.
I wanted to try SLI and bought another one today same make same model. now when I put the other one in and used the SLI, i noticed with most games (Metro last light, DOOM, FARCRY 4, Borderlands 2) it causes a green flickering at the start of the same and in the game. it does not occur with Battlefield 1 and the division)

I have also hear about the memory issues that some of these cards have with Samsung memory and Micron Memory. I looked the at memory details in GPU-Z and one of the cards is Micron and the other is Samsung.

I am also using the SLI bridge that came with my mother board which is the flexible one nor the HB bridge.

So what would be the problem, is it my bridge or is it the fact i have a defective card? will new drivers in the future help? will i need to flash the bios? should i just return the card and be happy with just one LOL?

about my PC:

CPU: Intel i7 4820K
MOBO: ASUS P9X79LE
RAM: 16GB corsair vengeance 1866MHZ
HDD: 1x SAMSUNG 250GB 850, 1 x intel 535 SSD 240GB and 3X seagate barracuda 3TB HDD
PSU: Thermaltake tough power gold 750W

I though it could be my PSU, but i unplugged most of the HDD and i was stil getting the flikering.

Your problem likely is you don't have the proper SLI bridge. The 10 series cards introduced a new high bandwidth SLI bridge, using an old bridge from a 2012 motherboard could very well cause problems. There was an issue with the Micron memory which got resolved with a BIOS update to the cards. Whether your second card got that update or not is unknown, you'd probably need to check MSI's documentation to find out which BIOS version fixed the Micron memory problems.

If you want to make sure that neither card is defective, then pull out both cards and try the new one on its own. If your new card has problems, it should show up when operating individually.

Thanks supernova. The issue indeed was the SLI bridge. I bought a HB one and no problems at all. Thanks for your comment
