The subject is the question:

I have two cards installed in a Linuxcoin machine. The two cards are a 5850 and a 5770. The 5850 is installed in the first 16x pcie slot, the 5770 with a 100% working riser in the second (1x) pcie slot.

The Mainboard is an Asus K8V-XE, Bios version is 0401.

Console output:

user@linuxcoin:~$ AMDOverdriveCtrl -h
INF: Nr. of Adapters: 5
INF: Adapter index: 0, active, ID:8819696, ATI Radeon HD 5800 Series
INF: Adapter index: 1, inact., ID:8819696, ATI Radeon HD 5800 Series
INF: Adapter index: 2, inact., ID:8819696, ATI Radeon HD 5800 Series
INF: Adapter index: 3, inact., ID:8819696,
INF: Adapter index: 4, inact., ID:8819696,
Usage: AMDOverdriveCtrl [-h] [-b] [-a] [-c ] [-i ] [profile name]...


If i install the 5770 in the first pcie slot it works, then i got two adapters, index 0 as active and index 1 as inactive.

I have some linux experience but no experience at all with mining bitcoins on linux or Linuxcoin.

Any idea?
