Look at hte ReadMe for TRM miner for some settings - I'm getting 49.4 mhs on my flashed 56 to 64 at 1050 850mv
tried their weakest settings
after applying it and started mining again the hashrate increased to 47.6 mh but after 15 to 20 minutes the system always hangs
i have to restart it to start mining again and it says radeon settings have been reset
i do not think the card is working stable with additional modification
