this is not for newer motherboards. It is for older motherboards taht only do 4x. Some of them wont post with the 8x agp radeons unless you basicly force it into 4x agp mode. I really wish I would have taken pics of that card before I sold it. I really hate this. It works very nicely and is easy to do. I just can't remember exactly which two leads to put the tape on. By leads I'm refering to these:

Um that is actaully a pic of the back side of a radeon 8500 but it's the same. Gold leads on the bottom of the card that fit into the agp slot. You simply cut a pice of tape to only cover just a single lead. There are two pieces of tape you can place on two seperate leads that will force it to run in 4x agp mode.
