Bump the Frequency to 1152Mhz and Lower VID (which raises the voltage) on the Miner General Configuration page. There are instructions on that Miner General Configuration too. Read those for sure.

Try frequency 1152MHz and then try adjusting VID between 22-14. Should get faster as you approach 14, probably will get the best rate when VID is somewhere below 20. I still haven't explored what's optimal for my machines. Waiting for the warranty to expire before I mess with overclocking but I overclocked my own A4 Dominators and it worked the same way.
