I had a system running 2x 670's in SLI on Win 8 on a dell 2711@1440

Upgraded to Win 10 and my z77x-d3h MoBo will not recognize my 2nd nvidia 670 in the (2nd pcie slot ) pcie 8x slot. The cards will work in non sli when installed in the 16x and 4x pcie slots!

After much messing about (both 670 cards work fine) I have decided its because of a lack of driver support from Gigabyte for their MoBo. My Sensai mouse caused loads of problems so that's going too lol.

For context I don't play competitively. I dont want to pay any more than about $50 to get it sorted.

So Im left with the question what should I do?

Option 1 keep the MoBo and sell the 2 x 670's to get a 1 x 970 (looked but couldn't find a benchmark for this scenario)

Option 2
Upgrade the MoBo (and therefore cpu) so I can keep the 2 670's in Sli (cost restrictive?)

Option 3 just keep the system and as it is and sell 1 of the 670's

What would you do in my situation?

F18i bios make sure your mb has the newest bios code.

newest inf driver.
in the bios see if there pci bus pseed for the pci slots asus does. see if both cards work in the slower 2x mode.

also check the mb guild see if that slot is sharing irq or memory range with another slot or device. if it does share try turning off printer and com ports to free up irq 7/ and some others.

Thanks for he responses.

Do you mean a clean install of win 10 as the update from 8 was online.

I am running 18i and have updated inf. driver.

Not sure what the other advice means. I wish I did.

Hi somewhere,

I have looked at the link but it's been longer than 30 days since I upgraded.

I am going to try a clean install.

I notice Windows 10 has a reset built into it. Should I do this or a full bells and whistles clean install to try help solve my problem

Thanks for the advice

I'd do the full clean reinstall.
