Is your 5850 installed in the orange PCI-e slot or the green slot PCI-e?

Make sure your HD5850 is installed on the top PCI-E slot, which is usually always the 16x slot.

Hello and welcome to the forums :) 
As shadow said make sure you have installed it on the top PCI-E slot not the second one

Hey

i seem to be having the same kind of problem with my asrock 790gxh mobo

i put my 5870 in the top x16 lane but it reads in CCC and everest and GPU-z as its running @ x8

also it seem that my bandwidth on my video card is only 116.2GB/s when it should be something like 153.XGB/s

anyone got any leads?

Kind Regards

There's something enabled that causes slots to drop to 8x. I thought it was USB3.0.
