OC settings only applies on first GPU

Hi,
I am facing a strange issue on my HiveOS rig, when I’m trying to apply OC settings I’m getting the following errors:

Did a couple of reinstalls, reboots, tested with several drivers and still the same result: OC setting only applies of the first GPU (gpu:0).

Any advice?
Thanks!

Did you ever figure this out? having a similar issue. 3 cards work, 1 won’t.

Hi @Selomine,

I have managed to solve my problem by removing HDMI dummies from GPU’s, after that everything worked like a charm. However I noticed that it doesn’t make any difference in hash rate even if you plug or unplug the HDMI dummies.
