So I'm doing some SLI testing on a fairly modern AM3+ motherboard with 990 FX chipset.

With older graphics drivers, the SLI option doesn't show up. But with newer ones it does. The 990 FX chipset came out in 2011, and that's pretty much when the Nvidia drivers offer the SLI option on this machine. I take it that because AMD licensed SLI in 2011 for this chipset, it will only work with drivers from that year onwards.

Now, is there a way to enable SLI support in older Nvidia drivers? Some sort of registry mod or hack?
