GPU Not in Device Manager

[RayKGamijg]

Hi everyone, I have a Pentium g4560 CPU on an Asus Prime z270-a motherboard. I have a 1060 and a 1070 in full slots. I know for a fact that both are functional. However, when I open device manager, display interfaces, the 1060 doesn't show up. My miner isn't detecting the 1060 either. 

This could be a problem with PCIe lanes. The Pentium only has 16, and each GPU would theoretically take up 16, making 32 which is too much. However, the board is capable of using x8 instead of x16, so I am very confused why the 1060 isn't detected. Any help is appreciated! Thanks!

might have to go into the bios and find the pcie settings and tell it specifically to run them in x8

the motherboard will auto detect the speed and make the changes necessary. if that setting in bios was changed manually it would still be detectable in the OS only speed would be compromised.

 

I would suggest pulling both cards out and placing the 1060 in the 1070 slot. keep the 1070 out for now and restart.

 

if detected do a stress test make sure it passes.

 

once done. if were all good there. take the card out and do the same with the 1070

 

try placing the 1060 by itself after testing into the second slot - some mobos will let u do this some dont, might require a card in slot 1. if no screen then try

 

 adding both cards in but in reverse of what you had.

 

if you get errors while stress testing "properly" then u know its a card. 

If done all the above switches with the slots and u find that no matter what card is in the second slot its not recognized then u know its a defective PCIE slot

I had this issue trying to run an old gts 8800 along side my gtx 1070 .. the 8800 wouldnt show up whatever i did and whatever Pci-e slot i used.. its stupid windows 10 unable to comprehend that there are two cards of different make an model i never got it solved so i threw out the 8800 and put it in my P4 3.2ghz machine for shits n giggles ,)
