Here is how to make up a dummy plug for your card in about 30 seconds.

All you need are three 68 ohm resistors from RadioShack. They come in packs of 5 for a buck.


You will need the DVI-VGA adapter that ships with every GFX card, the resistors and a clipper. You could use scissors or a nail clipper, the wire is soft.


Bend one leg of the resistor around till it is parallel to the other then clip off the long leg so it is the same length as the bent leg.


The wire is just the right gauge to slide into the VGA plus securely.


Push it home. Note you want to bridge the top three pins on the right with the pins directly below one-to-one.. Hold the plug so the wide part is up top.


Alternate the resistors so the leg of one is against the body of another to avoid shorting out the jumpers.

And that is all there is to it. Start Folding on your second GPU

It's for folding with multiple cards. It's needed as a "trick" to fool the cards into thinking that monitors are hooked up to all the cards, when in fact, the monitor is only hooked up to one card.

Gollie had a thread on this here.

This might be useful:


I have made a few of these and they work well. I used 75ohm resistors and it worked too.

The thing that I like is that CD's method doesn't involve soldering.

True, soldering those is difficult especially if you have a solder "gun"

Awesome, thanks CD. I just wish I knew this before when I had just got my 2nd 8800GT. I'll have the 2nd rig built in the next couple weeks most likely for folding, which only has one pci-e slot.

That is the diagram I went by.

Thanks for the add


Yeah I pretty much solder if I have to...but I do not have a decent soldering rig and I was looking at getting one for $100 and thought WTH am I doing?

I think any resistance value between about 50ohm-150ohm should work. RadioShack has 68ohm and 100ohm in stock.

Now I might have to do this and put my x850agp back in as primary and see if it cures the "unstable machine" error.

Mine is still kind of wierd. It will only run right is Monitor is on ""3" but when I want to go into BIOS I need monitor on "1" lol...so I have to sap the plug and the monitor back and forth when tweaking...no biggy.

I also see that the second card is Folding slower... not a lot slower...but slower. I've set each client an affinity to a core...but I don't think that's it.

This is incredible, I've been wanting to do this with my backup card haha!

If I was to add something like an 8600gt and 8800gs, would it hurt my 8800gt's 5kish ppd?

I just did what you have listed here, w/100ohm resistors-works without a hitch. I didnt solder them , i just put a slight twist to bind it in.+
