SLI Hack Help!

post #1 of 6
Thread Starter 
I know there's probably a million threads out there asking for help, but I've searched and searched, and read most of the official SLI hack thread, but I cannot get the SLI enable option to appear in my NVIDIA control panel.

I've used the latest patch as recommended (1.0), and the optional OS to load (Windows 7 x64 SLIPatch) does appear at boot time, and loads fine when I choose it. Problem is, the NVIDIA control panel still only gives me the option for PhysX options, rather than having SLI options as well. I have two GTX460's, which are both the EXACT same model, same brand, same VRAM, same clocks, everything. My board has 4 PCIe x16 slots, and the two cards occupy the top two 16x slots.

I am sitting on older drivers (260.99) with the SLI patch installed, but I have tried the latest drivers as well with the patch. I cannot install anything before/at 258.**, even with the old drivers removed, so that's a no go, but this doesn't explain why I have seen plenty of people get it working with drivers of the same version as mine. It really doesn't make sense!

The only thing I can think of, I know SLI doesn't depend on a SLI bridge to function, but it can enhance the performance since the data can travel between the cards directly. Would not having a bridge stop the option from appearing? I know a lot of people get it working without it, but it could be a possibility?

I have the GIGABYTE 890FXA-UD5 board which has a chipset that has been confirmed to work, as well as multiple cases of people getting it to work on this specific board. And yes - I have tried several times to reinstall the patch, remove the drivers completely. I have also used the nv_disp.inf supplied in the official thread, but none of it makes any difference.

I'm open to any suggestions as I am really frustrated I cannot get my brand new $340 card to work with SLI, which is what I was intending when I bought it.

EDIT: Just noticed in GPU-Z that it reports one of the cards is in a PCIe 16x v2.0 slot, while the other is in a PCIe 16x v1.1 slot, even when the documentation for my board says all slots conform with the v2.0 standard. Could this possibly make any difference to my outcome?

the SLI bridge is required for SLI with Nvidia Drivers 260.xx up....

it is just the way of things....

i used these drivers with my 480s in SLI without a bridge


they will work with your 460s as well

Uninstalled ForceWARE 260.99, used Driver Sweeper to remove the leftovers in safe-mode, and got the 258.99 drivers installed. To my surprise, I boot up and NVIDIA control panel tells me that having a SLI bridge would give optimized performance (yes I will go buy one). Thank you so much
