I wanted to make a How To that's as easy as possible for people to understand and most importantly, visualize. Also, due to a Christmas gift, it's the first time I've had to make one since it's the first time I've had an SLI rig since I SLI'ed some 9600GSO's.
Here we go. First off, for each plug you're going to make, you need an adapter plug and three 68-Ohm resistors. You can buy the resistors in packs of 5 from Radio Shack for $1. If you've ever bought a video card, you've probably got a few of these DVI-VGA adapters laying around:
Next, the resistors:
Take out three of them. Note that the metal "legs" coming off of these things are extremely easy to bend. Bend one leg of the resistor around the body and pointing down, in-line with the other leg like so:
Then, using wire cutters or even scissors, cut the legs evenly. Drop just 1/8 of an inch or so below the tip of the shortest leg and clip/cut. I suggest doing it this way because then, both legs are slightly pinched by the cutting process and tend to stay in the adapter much better.
Here is the guide you will be following for inserting the pins. One leg goes in at the top, then one at the bottom of each of the highlighted holes. Notice how I've highlighted and attached the holes. The legs of the resistors go into the top hole and then the other leg goes into the hole I've drawn the line to. Pretty easy to see what needs to be done:
The first resistor inserted:
All three inserted. Notice how I've staggered the orientation of the resistor's so that the legs stay well away from each other. This will keep the legs from touching each other "just in case."
Top view with resistor's bent over so you can see the holes each is inserted into:
I took the additional step of taping the resistor's up. My computer sits on the floor on wheels. I wheel the computer around a little bit to vacuum up dust and animal hair and was afraid the back would hit something or a wire get pulled and crush the resistor's into each other. If the legs make contact with each other, I have no idea if it would short the card out or not, so I'm taking this extra step for caution. Use either electrical tape or friction tape. I like friction tape because it doesn't just unwrap itself like vinyl tape does.
First resistor gets taped:
Second one. Notice I used a small screw driver to pull the tape down the legs before moving on to the last one:
All done. Three minutes per plug if you have your materials laid out.
It's as easy as it looks too and it works great. Enjoy!
