EVGA GTX 650 Ti BOOST SLI options not showing up in nVidia Control Panel

I can't get my nVidia Control Panel to show SLI options after installing my second EVGA GTX 650 Ti BOOST SLI and some help would be greatly appreciated. From following instructions, the options were supposed to show up after Windows' hardware changes' auto-detect under "Configure SLI, Surround, PhysX", but only "Configure Surround, PhysX" shows up. Thing is, they were both detected by Windows and both GPUs show up in the Device Manager.

Here's some information about my rig and what I've done so far:

System:

  • OS: Windows 7 Home Premium 64-bit (6.1, Build 7601)
    Motherboard: GA-990FXA-UD5, Gigabyte AM3+ Ready, CFX and SLI Ready (Rev 1.x)
    BIOS: Award Modular BIOS v6.00PG
    Processor: AMD Phenom II X6 1100T Processor (6 CPUs), 3.3GHz
    Memory: 8192MB RAM
    DX: DirectX 11
    GPUs: EVGA nVidia GeForce GTX 650 Ti BOOST x2 w/ 2-way SLI Bridge
    GPU Main Driver version: 9.18.13.3193
    GeForce driver version: 331.82

What I've done so far:


  • Reinstalled any and all drivers associated with my GPUs
    Tried to flash BIOS from factory version (From F2 version to F4 version, couldn't update to any more recent version from F5 to F12, all these versions were causing BSOD's for a quarter second and immediately restarting my PC when trying to load Windows 7, some help with this as well would be welcome!)
    Tried to force SLI with a software named HyperSLI, but wasn't successful, with the 2nd GPU remaining idle even through benchmarks (although I'm not surprised, since HyperSLI hasn't been updated in several months if not longer)
    Tried with another 2-way SLI Bridge, same issue
    Switched GPU's places on the motherboard, nothing changed

    I haven't found a single definitive solution to my problem on the web after searching for hours and hours, as most issues similar to mine had Windows not detecting one of the GPUs, which isn't the case with my issue.

    I'm pretty sure I tried quite a few more things, but it's getting pretty late and the memory's getting fuzzy.
Any help would be greatly appreciated, hoping to get this SLI working!

hmm ok, sorry i didnt mean to imply that you dont know what you are doing or anything, sometimes it can be the smallest thing... i did some checking and it seems as though it may be a bios issue, i also saw someone who had to out their card in a different (8x) slot

hmmm, do they both show up in the nvidia control panel-> configure surround, phys-x -> maximize 3D performance?

if so, have you tied using jus one card (and swapping between them) to make sure they are bosth working?

lastly, does your motherboard definitely support SLI? many motherboards support crossfire, but not SLI.

Yes, they both show up in nVidia's control panel and I did try them individually. Both are working fine.

And yes, the GA-990FXA-UD5 is SLI and CFX ready, it's written on the motherboard itself and I got 2 SLI Bridges included with it. :p

I tried again with only the base drivers from the Driver Installation Disc provided with my newest GPU, with no success. I'll wait for some more solutions and I'll try formatting my PC if it still doesn't work. :(

No offense taken, I'm really thankful for your replies. :)

I tried updating my BIOS yet again, and it worked. Somehow. Why? No idea, since it's the same latest BIOS update I've been trying to install since last Thursday, and I don't think I've done anything significant enough to make it work. Anyway, now my SLI is enabled and working well. Thanks for the help.

no worries! im stoked it worked out in the end! pc's can be quite temperamental at times :/ i dont think you will ever find a suitable answer to why it wouldnt install before...

ive had a somewhat similar problem with my motherboard, but with ram, tried everything, took it apart and put it back together a few times, tried different parts and no luck, it just wouldnt start, eventually out of frustration i gave up. went back a few days days to try again, pressed the power switch and it worked perfectly, and has been ever since! i just took the win, ive got no idea what was causing the problem
