Hi can anyone help with an issue I am having with a pair of HD5870 GPUs, both cards work fine when installed one at a time. I have a Corsair AX860i powering my PC. the problem is when I install a second card the PC will boot and show the second card with an exclamation mark indicating an issue. The details on the device shows the following error “The device cannot start (Code 10)” when I reboot the PC it will not boot into window until the second card is removed.
 
I have already eliminated the cables in this way, I have also have a set of cables that power 2 cards that came with my PSU, this behaved in exactly the same way.
 
Both cards work fine in slot 1 or 3 so not a slot issue, I could update the BIOS but I would lose my overclock as it was a bundle from Overclockers.
 
Well after 3 days of F*!king on trying to get the second damn card to work I have given it up as a bad job! even though it looks kool sat atop my PC its about as much use as concrete parachute. I will have to wait a while and get a new GPU so not such a cheap upgrade after all, just bling.
 
Issue has now been resolved, it turns out the water cooling pipe between the 2 GPUs was slightly to long, this forced the card over slightly in the slot resulting in the strange behaviour of the cards when installed together. Only took 3 days to work out! well you learn new things every day, thanks for all the input.
