Sli?

[retsteel]

I don't know if this is quite the correct forum for this but I was recently playing around with an old rig that I put together from some parts that I had sitting around when I noticed that the video cards only had one little sli pluggy thing, also being curious I slied them, and they worked like that (until I fried them, separate matter) anyways my good rig does not have an sli setup but the card has two sli pluggy things, my question, why two?

so it can support up to quad sli as long as you buy 4 of those same cards.........

Most high end GPU's allow this, you can have up to four cards (of the same GPU) working together.

Your motherboard must also support 4-way SLI for this to work.

okay, I am really new to multiple graphics cards, been building for a while but never had the occasion to play with them I always just assumed that you got an sli bridge with more ports for quad sli? but do you daisy chain them?

This is what a quad SLI looks like:

The bridge just offers up the communication between the cards to sync the display output, the data still goes through the main PCIE connectors.

This image shows what a 4-way SLI bridge will look like.
