Hey guys. I just received my three diMond 280x's and installed them. But lo and behold I don't see any crossfire cables included. Wtf? Is that normal? Now I don't even know which models to get to fit my cards? Will any of the other manufacturer cables work? Will a HiS cable work? I heard that diamond is basically the same as the HiS. I'm kind of pisserd off that I might have to spend another 30 bucks to get these stupid cables that should have came with the video card. If you can shoot a link to where I can get these. bales fats that would be great.
Also is ere anesy to get the cards to work with mining without the cables? Or is that impossible too. Thanks all.
 
pretty sure you don't need any cables to use those separately to mine. Well, I am sure you don't I just haven't done it personally. That's funny they didn't even include them, maybe they figure it's unnecessary at this point.
 
You don't need the cables if you are only going to mine. You only need the cables if you are going to crossfire the cards for gaming and/or applications that would support it. Having crossfire enabled while mining can potentially decrease hash rates.
 
Thanks guys. Good to know. I'll just have to configure them properly later then. you CAN wire them up for crossfire, and just disable crossfire in software right?
This will be a mining/gaming hybrid...
Also, do any of you guys have experience with the diamond cards? They dont have their own OC utility. what do you guys recommend?
 
Yeah you can disable crossfire in CCC. You'll only need two of these.

The only differences are that there are two different lengths.

You can get brand new ones off of Ebay for $3.99 shipped, which is less than half the price in the Amazon link above.

As for overclocking utilities, use MSI afterburner. You can get the latest release off of Guru3d.com

Awesome. Thanks. So there's no problem using a diff manufacturers oc utility? I'm assuming the biases are diff? Mem timings etc?

Crossfire cable should come with the motherboard (spacing between pci-e 16x slot is not always the same). Like others have suggested ebay would be a good place to get some cable cheap and you should not need any for mining.
Msi afterburner or Evga precision X are the 2 best OC utilities imho and they work fine with all cards (not just their respective brand)

The longer Crossfire cables are fine to use with any board as crossfire cables are not rigid like SLI bridges.
 
Took a peek in my XFX boxes. XFX includes CF cable with the 270X but not with the 290X since it doesn't need it and utilizes PCI-E bus.

I don't have any explanation for this and it's pretty off topic, but screw it:

I had a NIB 7950 and a NIB 280x and I crossfired them for giggles. I wanted the 280x on top, but I could only enable crossfire with the 280x on bottom... this really irritated me and I had time to mess with it for a while.

Finally I used the crossfire cable from the 280x package and crossfire worked with the 280x on top.

Those two crossfire cables couldn't have been exactly the same, could they?

Edit: The 7950 was a Powercolor, which I stupidly sold for $165 just before the mining boom (It died a month later and was replaced o_O). The 280x was a Sapphire Dual-X which I liked a lot but stupidly returned after buying it for... $274.99. Decided to go 780 SLi instead and I'm much happier with noise levels this way. Oh well, at least the 780s were cheaper by then because the mining shit was really taking off, but I certainly didn't read the signs right about when to sell and how high on the Radeons I had.

That is actually quite strange. A crossfire cable is nothing but a ribbon cable with ends on it. There are no electronics.

Maybe the older crossfire cable wasn't getting a good enough connection or was slightly messed up (too much resistance through one or more of the traces).
