The number of the CUs is not a problem (actually they are reported by OpenCL as 36). Something else is going on in your case. Make sure that all hardware control options of PhoenixMiner are turned off (i.e. remove all -cclock, -mclock, -tt, -cvddc, -mvdcc, etc. parameters), and set the clocks, voltages, and fans via the AMD control center software. You may also add the -hstats 2 parameter to see the actual clocks of the card when mining.
Thanks for the reply. I have everything set in AMD Radeon software. The
-hstats 2 parameter is reporting same values as are set in Radeon software. Im running driver version 20.12.1. Any other ideas where could be the problem?
So I experimented with the settings a little bit and I found out that if I set my Memory speed to 2150 (MAX) my hash rate is around 20. But if i lower it to 2100 my hash rate goes to 62. Any reason why it's behaving so weird? The card is stable, temps under 50.
