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.

Check the power cables to the second card are both working OK. Plug the second set of cables into the first GPU with just the first GPU enabled.
I had a similar issue when I set up my 5870cf. TO get it working i had to:
Strip out the AMD drivers
install the second card on its own and let windows find it
Install first card, and agin let windows do its stuff
Finally updated to latest AMD drivers and all working good.
HAve you swapped the cards around?

Could be the slot knackered but that would be unusual. Can you try booting up with a GPU just in the second slot? I assume you've checked it's properly in the slot?
The only other thing I can think of is to update your motherboard BIOS but that wouldn't explain why it was working before and now isn't.

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.
