well this sucks. i bought this pcie 1x to 16x, plugged it into an 16x slot on the motherboard but the system wouldn't boot (no video and doesn't POST). guessing it needs to be plugged into a 1x on the MB but my MB doesn't have any of those slots. was basing my cable choice from this picture http://super-key.com/phones/oc/oc06.JPG it would appear they have a 1x to 1x cable plugged into an 16x slot on the MB and figured my cable should've worked.
anyways, ordered new 16x to 16x cables and will try this again.
