sli issues, PLEASE HELP :(

[crosis]

ok, so i have a fun one....

 

i own 2 rigs. one for me and one for my gf. i recently upgraded my gpu and decided to put the old one in sli on my gf's rig, giving her 2 gtx 780's in sli. it is on an msi z87-gd65 gaming motherboard. finished installing and booted, but no sli option where it should be in the nvidia control panel.

 

i tested each card individually, they work. 

i swapped locations on the motherboard, still no sli option.

i read the manual to make sure they were in the correct pci slots, they were correctly in slots 2 and 5.

i switched them anyway, obviously no improvement there.

i popped out both cards and put them in MY rig- worked like a charm.

i attempted using ddu, to no avail.

i tried a completely fresh install of windows and all drivers- no luck.

nothing on the motherboard, gpu or bridge show any sign to suggest fault.

i am at the end of my rope on this one. can anybody help? pretty please? im begging.

so it just isn't registering the second card? or does it just not allow you to SLI?

Were you using the same SLI bridge when u tryed it in your computer?   swap out the SLI bridge.

[WolfDeville]

Make sure you don't have one of them in an 4x lane and have an SLI bridge connected.

[crosis]

i used the same in both systems. i also grabbed a second bridge with the same results.

Also i think this would get more views if you posted it under the graphics card section as it is a graphics card issue.

Also try putting her current card in the PCI slot ur putting the 2nd card in and running it as a single card. the PCI slot could be ded.

singular cards working in either slot
