Crossfire D' 4890's Wont got at x16

[jlear3]

I have a MSI 790FX-GD70 that is supposedly capable of 2 slots @16x or 4 slots @8x, but when i throw 2 xoc'd diamond 4890's they are listed in gpu-z as 8x, both.... i know it prolly wont make much of a diff. but i'd like stuff i spend money on to work.

Are you sure they are in the right slots? That might throw it off if they aren't both in the x16 slots.

And yeah you won't take much of a hit if they are both at 8x if any noticeable one.

I'd think so, the first two, but i read somewhere it should auto arrange anyways, well geuss a manual will just confirm lol

 

[jlear3]

well, you're right, different slots render x16 but i think it looks cooler right next to eachother so i might keep it that way lol

Your not going to hurt it really. I doubt your losing more then 5 fps if at that. You can just test it both ways and see if you think your losing to much but no cards use up the full x16 anyways.
