Love how no one answered this, just suggested buying new hardware. I am curious as well, not really because I am going to do it but because I help a ton of people fix their systems on a regular basis using only what they have available. So can this be done at all in crossfire?
I understand it may be less efficient than using one better card....I get it and I am sure OP got that too. The question is, can it be done?
edit: I do not mean using the OP's cards, any card at all that fits the slots. Is PCI-Ex1 and PCI-Ex16 able to be crossfired together at all?
MB has two 2.0x16 pci slots, four x1 pci slots, then one pci slot,
Two 3 radeon HD 5570 in my two 2.0x16's
One pci x1 single tv tuner
One pci x1 hdmi input card
One pci x1 5.1 sound card
And one pci Wireless adapter card
I have a pci x1 to x16
i have a pci x1 90 degrees left
So to fill my last x1 slot why not add to the graphics? So i put the pci x1 90 left to my last pci x1 (its my first slot looking from the right) then i put my pci x16 converter into that, so i end up with a x16 pointing, then i ran into a problem, It wouldent fit =(, so i took all my parts out of the case and went out and drilles a nice square in to the side of my case, xD, put everything back in there and it fit perfectly other than about 1 1/2 inches of the card sticking out, so i was hookeing up crossfire and i ran into another problem, my bride was to short, now what to do?, well i got 2 bride conectes and spliced them and put them back toghter, o.0 veryyyyyy hard with those small of wires, hooked it all up and, and it gave me the slightes increase, like 1/3 of regual card, but hey it still ads to my other two cards and it fills up my other pci x1 slot
all in all did it work? yes, is it worth it? no
other iinfo: i have a 6 core AMD Phenom II X6 1100T cpu
seven 2tb hdd, 1 60gig sdd (yes 14tb in a HTPC case)
16gig of 2133 ram
