Hi there!

Been trying nvOC 0012 after OP pointed me to it in another thread and liked it but went back to my own installation for stability reasons and some other things i missed or didn't like. Still I'd like to say thanks for all the work devoted into nvOC and for sharing it with the community!

Now I got my hands on a nice 8xGPU supermicro 4028 case (X9 board inside) for a couple of days (already feelin' sad that I'll have to return this nice machine) and for the sake of simplicity thought I give nvOC another shot (v0017 this time).
After applying my settings to oneBash I fired up nvOC and found it mining smoothly albeit I didn't manage to get a desktop displayed on any of the graphics-ports (tried pretty much all display-port slots of all cards, especiall GPU #0 which was not easy to find out which one it is (inner left if viewing from the back)). the onboard vga-port shows the ubuntu typical purple background but i cannot see anything else on it.

Logging in via ssh works though so I went on checking temps and stuff and found that the fan-speeds were like I configured them for GPU #0 to GPU #3 but running on default for GPU #4 to GPU #7!
Miners were running on all GPU's present, did not find out how to check OC-settings but I suspect only the cards with set fan-speeds will have their OC-settings applied.

Digging a bit deeper into xorg.conf and the output of nvidia-smi I noticed the the graphic cards PCI-device-addresses on this machine do not start at 01 and go up sequentially but are 04, 05, 08, 09 and 84, 85, 88, 89. The cards in the lower addresses had their fanspeed applied correctly, the 8X ones not.

Inspecting nvOC's xorg.conf I found the there are entries for graphic cards on addresses 01 til 14 which might nicely explain why in my case only the cards within this range get their settings applied. So I went on and changed some other device-entries numbers to 84,85, 88, 89 hoping this would do the trick.

Sadly it didn't, behaviour was just like before.
My guess is that these numbers are hardcoded in some other config somewhere in the system and I might need to alter this as well. Any ideas where else I might need to look?

Thanks in advance,
pain
