Solved!!! Was able to run at 30Mh/s but I wasn't comfortable with too many memory errors/hour.

Ethash:29Mh/s temp:66C power:85W errors/hour:27/3



started with original bios then with PBEv1.6.2
- applied one click timings
- upped max fan speed from 3000 to 3300
- upped the core voltage@300 from 750mv to 824mv
- changed core voltage@900 to 65282
- changed core voltage@1145 to 65282
- changed core voltage@1215 to 65283
- changed core voltage@1257 to 65283
- changed core voltage@1300 to 65283
- changed core voltage@1365 to 65283
- changed memory voltage@2000 to 1024

MSI AB setting: 1145core/2100mem/80% fan
Trixx setting: 1145core/2100mem/-108mV
