A side question, for the R9 Nano, if I'm running headless, I can't seem to view the core clock/memory clock/temperature/etc. Only able to see them with monitor attached.
Is there any workaround to view them when running headless? By the way, I'm on Win10. Thanks.
Sounds like a driver issue, all my rigs are headless and i can monitor everything without a problem. Also Windows 10.
Reinstall drivers mate. That'll probably solve it

That's weird. I have tried to reinstall driver but still the same. Using 16.5.1 driver.
I have other Nvidia cards on the same rig but I don't think that has to do with it coz I did try to remove Nvidia cards but still the same.
Maybe I should try other driver versions...
