It can be worked around using Afterburner and it's "ULPS" override setting - usually.

Hello,

I've got a Sapphire Nitro R9 Fury and a GTX 1080 in my PC. Everything was working just fine until yesterday. Suddenly the Fury goes from 31MH/s down to 8MH/s - but only if my monitor is plugged in to the GTX 1080. If I plug the monitor into the Fury, it goes back to 31MH/s.

I haven't changed anything, same drivers, same Windows, same everything.

Got Windows 10 Home 64bit, i5-6600K, 16GB RAM, 16.5GB swap file. Using 17.4.3 drivers for the Fury and 382.05 for the Nvidia card. Like I said, nothing has changed since the sudden lower hash rate.

Any ideas?

Edit: I've tried Claymore's ETH miner 9.2 and 9.3 with the same results.

Edit 2: I was too quick to write, I guess. I solved it by plugging in another monitor to the Fury card. However, I did not have this monitor plugged in previously, which makes it weird anyway.

You might need some dummy plugs. Didn't know this was still an issue for AMD.
