Building my First Mining Rig 2xHD6870 on ASROCK|890GX

[JimmyBTM]

I built my first mining rig from the ground up today using 2 HD6870 GPUs and plan on adding a 3rd in a few days but I am having issues getting gui miner to see the new cards?

its on a ASROCK|890GX motherboard

and I am trying to do this in Windows 7 with gui miner

and in device manager I can see the display drivers as loading the cards properly
but it still isn't loading in gui miner
or in amd overdrive

if I change the bios to default to pcie
then I do end up seeing one card but not both??

any suggestions or help would be much appreciated

Goodluck to you, sir.

Sounds like a Crossfire thing. Did you call Microsoft Support? Does it work under Linux?

In windows, you need to plug in a monitor or a dummy plug for guiminter to see your cards properly.
