how do you tell how many errors your getting? and what cards and how many??
Getting actual miner error codes with 14.4 driver, as in missing OpenCL function bla bla during start up, still working but slow.
3x 7970 underclocked to 850MHz gets me 825h/s with 13.12 driver, about 275H/s per card@850MHz@0.912V
Trying higher clocks and other driver versions now...
