SLI Hack performance

post #1 of 10
Thread Starter 
Sorry if this is the wrong place to post this question.

I have recently upgraded my GPU to a Sparkle x580 and really want to add a second for SLI. I have SLI hacked my board but I am interested if when I do SLI the 580s will i notice any performance issues compared to if I bought the CHF4 extreme.

Thank you in advance

None at all. The SLI hack is all driver related so there will be no slowing of any hardware, and both cards will run at full potential.

No, the performance will not be changed. As i said, all the SLI hack does is enable SLI in the chipset drivers, which is disabled by default.

theoretically you are right.. my opinion depends on the pcie speeds the board provides .. for e.g. 16/8 16/4 8/8 8/4.. this would make the difference.. or tell me if im wrong.

His board is a Crosshair Formula, it has plenty of x16 lanes.

Nope minimal difference like maybe 2-3% maybe. When i had sli hack on my mb and 2 470's one of my lanes is 16x the other is 4x. I also have another rig exactly same minus a official asus sli mb with 2 16x lanes fps were same all around.
