Requirments for sli

[Stemz]

So i was having issues with my last mobo so i decided to switch to this asrock extreme 6...i went out and also got a samsung 950 pro the problem is i cant seem to get sli enabled i know my gpus are know running at x8 x4 and the ssd os taking up the x4... Is the ssd the reason im unable to run sli?

I would read the manual to your motherboard. It isnt unheard of to see a motherboard that wont allow GPU to run with only 4 lanes. I've also seen some that wont allow the lanes to be shared between a GPU and hard drive type device. The manual should cover all of the specifics though.

I checked gpuz and it shows that one gpu is at x8 and the other at x4 idk if sli requires both to run a x8 thats y im asking

Which extreme6 do you have? There's one for every chipset. But yes you need x8 for sli but the ssd should be able to go on another slot to not take cpu lanes and use mobo lanes.

Its the z97 one i can move it to the bottum slots its pcie 2.0 x2 but it would defeat the purpose of having a 950 pro lol but then again i have 2 gtx 760 and by it self it wont do to great

What are you doing that would even push the 950 to it's max speed?

Nothing id just like to know that the power is there if i ever needed it... I switched it and it said sli is available so yea that was the problem
