2-Way SLI with 4-Way SLI Bridge?

Okay... So I currently go to college in another state and I do most of my work on my custom built PC. It uses an ASUS Z-97 WS Motherboard, 16GB of RAM, a CPU, and most importantly a GTX 970. Now one of my mates here in college is getting rid of his old computer that also has a 970 in it. In fact, it is the same 970 that I have so I bought it from him.. Now I have 2 970's and I can SLI them together.

 

The only problem is, I only have a 4-WAY SLI Bridge (see picture below), not a 2-WAY. My question is, can I just use my 4-WAY SLI Bridge even though I only have 2 graphics card and just not plug in any additional graphics cards into the other two slots? The reason I'm asking this is because I noticed on my 4-WAY SLI Bridge that the connections made to the graphics cards are different depending on which card it is. Some have 2 connections and some have 1. What is up with that?

 

Any help would be appreciated!

 

P.S: I know I could just buy an inexpensive 2-WAY SLI Bridge, but I really don't want to spend anymore money than I need to!

Yes, it would work just fine.  You can probably find someone to give you a 2-way flexible bridge for free, because every video card comes with one.

Awesome, as for my other question, Why are there 2 connectors on some parts of my 4-WAY SLI Bridge, but only 1 on other parts?

It's just how tri/quad SLI works.  You need one set of fingers for 2 cards and then the other set of fingers for the other cards.  Probably some bandwidth splitting thing.

It's probably split up into effectively multi-layer 2-way SLI, where the two slave cards talk to the masters like a normal 2-Way SLI, but the masters are set up in their own 2-way SLI.

I have a blog! And a list of guides I've posted
