Can a faulty HD 7770 be crossfired with a working one? Urgent !

post #1 of 12
Thread Starter 
Title says it all. I can get a faulty HD 7770 (works but makes artifacts on screen) for $20 and crossfire it with the same model but a working one?

I will have the HDMI cable on the Working one.

EDIT: It is intended as a media PC but if i can get more power then i have no problem with the 7770.

Please help now because i will lose the opportunity

NO, It will not work, trust me.. I had this experience. You will be forced to trash the artifacting card DO NOT WASTE your money.

Depends on the nature of the fault.

If only the display outputs are faulty, then there shouldn't be any problems if your displays aren't connected to this card.

However, this does not sound like the case here. Connecting an unstable or artifacting GPU to a working one won't make the former card stable.

If you unsuccessfully get it to work out you lose $20 . But I dont think it will work any different when crossfire

I got it guys and crossfired it. By the way i got the faulty one for £16 and the working one for hahah £5 , got to love ebay.. no one else bided on the working one... anyway.

It did work at first, meaning i could run BF3 on max 1080p with stable 60fps, but.... then the fps dropped to 25.... removed the faulty one and i can play it at medium. oh well . at least i have an extra heat sink.. lol
