Im running the 5.5b version with my RX 6800XT however I'm getting only around 20 MHs. I tried different settings (even gaming profile) but still the same low Hashrate. Card temps are around 45C. Same problem on 5.4c. Somehow phoenix miner detect my card only with 36CU instead of 72CU, can I somehow correct this? Core at 1500, memory 2150.
