Crossfire two HD7750s

[acolombo]

I have two perfectly identical HD7750 and I'd like to crossfire them, but I don't know anything at all about how to do it.

Can you please help me to do it?

If I'm looking at the right card, you can't.

You don't need a crossfire bridge if i am correct, just the amd catalyst software

When you take a quick glance at the 7750 you will notice that the card doesn’t have a CrossFireX port on the top, nor do they come with a bridge for connecting two cards together.

This is not to say that they are not compatible.

 

All the bandwidth that the cards require is catered for by the motherboard and this therefore makes setup the much easier for the novice user.

 

Installation and initial setup is as simple as plugging the two cards in to two available PCI-e lanes and turning the computer on.  

AMD’s Catalyst software will then detect that two CrossFire compatible cards have been installed and prompts the user with a message asking if they wish to connect the two cards together harnessing the power of CrossFire.

if it has a crossfire finger, you can. If it doesn't, you can't.

(That's true with the 7750 at least)

It does, uses bridgeless/fingerless crossfire through the motherboard.

Read the post above yours, click the link, watch the video

Thank you really much, I'll watch the video when I get home from the university...

If I don't even need a bridge it's perfect!

Video states the text I put there basically.

 

Throw both in, "maybe' reinstall drivers, maybe not.. two should work straight away if not needing a driver install.

Awhile ago I too was surprised to find out about them not needing a bridge either. It's funny that AMD never really talked about it on the 7750 but made a big deal about it with the 290/290x.

I think the 7750 (and, of they did this on any other cards) was more of a "well... this may work, but we don't know for certain" type of thing, a beta test if you will. When it worked, it became a feature of the R9 series. That's my take on it anyway, as I remember reading an article not too long before the R9 series was announced of AMD confirming that it worked meant some being things were to come.
