It does absolutely nothing other than ticking a notch in NVIDIA drivers to support SLI. Hence why many here (me included) call them 'SLI tax chips'. They're just PCI-E bridge chips to uphold the 'SLI needs special NVIDIA SLI technology' facade even though that was busted with hacked drivers years ago.
