Miners Not Recognizing 3rd Card

[aceman1011]

Ok, so I have a rig with 2 5830s, everything's running fine. Now, I added a 6870, updated drivers, and all that, and am using a PCIE x1 to x16 adapter. Windows, device manager, and CCC all see all 3 cards. But when I try to use device 0 and device 3, device 0 is the CPU and device 3 isn't seen. I tried pausing at cmd, and Poclbm only sees the CPU and 2x 5830s. GUIminer also only sees the 2x 5830s and the CPU. What is the proble? Should I try wiping all GPU and ATI drivers and then re installing? Thanks!

are you using dummy plugs?

switch to Linux?

I am running Windows 7 with 2 5830s, a 5770, and a 6870 (4 cards) all working fine, overclocked, overvoltage, stock drivers, and PCI>PCIx16 adapters for 2 of them using phoenix. I do have to use dummy plugs though.

I have dummy plugs in all 3. I had to use the extend desktop function under properties before CCC would see them. Gonna try reinstalling all drivers now.

Fixed. And still using Windows! Apparently CCC 11.6 doesn't work with SDK 2.1, so I'm using 11.6 and 2.4.
