asrock z87 extreme4

msi 980 gaming edition LE and EVGA 980 FTX ACX 2.0

win 8.1

 

Just recently installed a 2nd 980, but for some reason device manager is not recognizing that a 2nd card exists. ASROCK's UEFI bios recognizes both cards are there, but only one shows up in device manager.

 

I reinstalled drivers, tried updating BIOS, nothing. Tried in reverse, nothing.

What if you flip the order of the cards around?

An AMD cpu has no place in a solely gaming build, end of.

I3 4150, Intel HD graphics, corsair CX750M, 4gb ram, Asus H81M-E, corsair 230T, Intel stock cooler WD Green 2TB Gigabyte 550TI

Why you shouldn't trust Gpu or Cpu boss Click on this I dare you!

If you connect your monitor to the second card, does it show something?

If not, make sure, it's seated correctly and that its getting power.

Also try the other 16x slot if the above doesn't help.

the other x16 slot is 4x only, tried reversing the 2 cards again. I had the msi one as the main one at first, switching the 2 around, it still says in gpu-z that the subvendor is msi even though the evga one is in the top slot, hdmi plugged into it to monitor. switching hdmi to 2nd card (msi), monitor gets no signal from it

yes

And if you use each card in the machine on their own (one at a time), they show up as the correct cards?

Do you have another SLI Bridge that you can try? 

I would try that, as well as different PCIe slots on the mobo.

You have 3 16X PCIe slots on that mobo.

oddly enough the bottom one allows device manager to recognize the bottom card but sli does not show up in nvidia control panel, but it does recognize there is a card there. As i suspected, the bottom slot is 4x only
