The RM 5600 XT works fine with standard settings of 40-41 megahash.
If you need to get a higher hash rate, then you need to flash the BIOS of the video card. Then you can get 44-45 megahash.
Different video cards may have problems, for example, the video output stops working, so you need to read the forums for each of the models.

I must have 4 bad 5600 XT cards. Running with the stock settings "core clock 1700" and "memory clock 1750" and the Power override via Afterburner set @ "power limit -10%" the best I get is ~38.2M/H.

One thing I have stumbled into with these cards is with the Power Limit @ -30% the cards are the most efficient miners compared to the Nvidia 1600 GPU's I have on other systems but they show many "stales" and hang Windows once a day or so. When I run the cards @ -20% the stales go away and the efficiency drops off slightly but the cards still cause Windows to hang once a day or so. When I run the cards @ -10% the cards are almost last on the efficiency rating but seem very stable and run at ~57c with the fans set a 30% minimum. Since going to the -10% setting they been running for 65+ hours with no issues and only 2 stales.

What am I missing?
