the above referenced article is incorrect though, I have 5 rigs all using 890fxa-gd70 (which are listed on the above article of boards that need to be jumped) I am using 1x >16x risers on all five and do not have a problem and do not have to jump any pins

this kind of modification can be very dangerous to many components if you do not know what your doing, be careful!

also you may want to buy extenders from cablesaurus instead of on ebay, his cables are probably better than most you find on ebay
