MSI Z77 M-power SLI + Physx not working

post #1 of 6
Thread Starter 
Hello guys!

I recently got a MSI Z77 M-Power, and love it so far, except for one thing.
I can not use SLI and a dedicated physx card (GT 630) at the same time. I can start up everything normally, and all 3 cards are detected properly by both nvidia driver and GPU-Z (Running 8x/4x/4x).
However SLI option is gone with the GT 630 installed, so why is this?

I really wanted to try out a dedicated physx card in some games I own, just to see if the performance gets any better or not. But it is kinda useless when I can't enable SLI.

Any help on the matter would be appreciated! smile.gif

SLI cant be enabled with 4x speeds even if it is at 4x 1.0 2.0 or 3.0 pcie. i ownthis board and there is nothing you can do about your problem. Maybe get a Pcie 1X card?

well the last pcie 16x (4x actually) is used for people that have crossfire. Crossfire can be used with 4x so people can do a 3 way Crossfire on it. I had no use for it either when i had 2 way sli gtx 580.

sorry that you have wasted your money on a paper weight. can you still return it? anyways physx is not that demanding, what games where you going to play with it?

Weird that nvidia limits SLI, should not be like that!
But its not a card that I bought for physx, actually it was a leftover from one of my clients, so no money lost smile.gif
But still a shame that I can't even try it.

And physx is quite a performance hit when you play at 2560x1440, at 1080p its not so hard.
Game I really want to try it out in is Planetside 2, as it is a really hard hitter with physx on!
