This is now my setup and its work nice for now, 50MHs on 114W:
-tt 62
-cvddc 750
-cclock 1250
-fanmin 0
-mclock 910
-amd
-acm
-mi 12
-gt 126
-mode 1
-clKernel 1
-clNew 1
-clf 0
-lidag 1

I am not sure if your -gt 126 is result from auto-tune or copy-paste from some other config. You can remove it, start the miner and when the auto-tuning finishes to take the best gt value from the last log and put it back in your -gt setting.

Also apply this advices from SerpentXSF:

Asrock Challenger RX 5700 (Non-XT) - I got it 24/7 stable with the following settings in Phoenix mining ETH. I also share some tips for those like myself who experience AMD drivers crashing and resetting their clocks in Windows. Check it out below.

Config: 0.850 vcore | 1350 core | 1840 Mem | 56.97 Mhs | 118 watts

I can get to 58 Mhs + but it is not 24/7 stable with current drivers, I also modified my GPU in past content released on my channel.
