Khenglish Posted October 3, 2014 Share Posted October 3, 2014 So it sticks to x4 if you load the GPU with something? If so I suspect you got your mxm slot dirty or damaged it when switching in the 780m. Quote Link to comment Share on other sites More sharing options...

Ezio21 Posted October 7, 2014 Share Posted October 7, 2014 Hello,On single gpu systems pcie speed is x16. On dual gpu systems it splits to x8 for a card. You won't have any use for x16 for each card because x8 is much more than single card use, even GTX 880M. So everything works correctly. On my system there are two Radeon HD6990M and x8 speed for each.Regards Quote Link to comment Share on other sites More sharing options...
