GTX 460 SLI NOT WORKING

I tried to sli a

MSI 460 GTX 1GB Cyclone with a

EVGA 460 GTX 1GB

It did not work. I tried every combination of ports and still did not work on my 980-g65 msi borad. I have a corsair tx850W PSU which can defiantly handle the load. Both cards work fine on their own in any of the 3 PCIE slots, but SLI'd they do not work. I have hybrid sli disabled and everything is the BIOS is how it should be. The only thing I can think of that could be casing the problem is:

Is it not working because the MSI card has a 256-bit memory interface and the Geforce has a 192?

Are different brands just incompatible? I've never heard that before?

Can you suggest a card that will work??

More about working
  1. They both are 1GB!!
  2. Double check the SLI Bridge for any Wear/Tear/Bend. You can also try different placements. (Switch the two cards and then try to SLI them.)

    It may be an incompatibility between different sub-types of graphic card. But normally it should work.
    Did you enable SLI in the BIOS and in Windows?

    Hope it helps! :)
  3. LOL they both are 1GB I POSTED THE EVGA official description and yet you still don't believe. Regardless I now know why they're incompatible.
  4. SO regardless what evga product description is you're right? :non:

    This is funny k thx
  5. I get that it was just the fact that you were arguing that 192 bit can ONLY be from 768mb

    Are you being completely stupid? im correct my friend.
    You CANNOT SLi 192-bit with 256-bit even if they are both 1GB.


    But I heard that SLI only use the first card's VRAM, so as long the first card is 256-bit, you should be fine, no?
