1. add virtual memory, 16gb per card
2. Make sure you use 23aug blockchain driver
2. re-enable both cards in device manager before mining
3. use cast-xmr miner
4. make sure your temps are below 70 degrees (both gpu and hbcc)

Thank you very much. increasing VM fixed the error message, now running consistent 1975 h/s per card without tweeks using default cooling on the blockhain driver. Still connected to onboard video (Intel). Wondering what I'll get with HBCC enabled. For some reason it crashes my AMD Settings prog as soon as I try to change it to anything.

You doesn't need HBCC for high mining speeds. Old tricks with HBCC was used as switching HBCC was causing card re-enabling that solves internal driver paging bug. The same can be done with just disabling and then enabling the card in device manager.
