I'm using claymore (tried 9.8,9.7 and 10.0) and have tried drivers 16.9, 17.4 and the beta block chain one, i've downloaded furmark but the card is always not the main driver so furmark just stresses the main driver and leave it
I don't quite get what you are saying here, what do you mean that it just stresses the main driver? Do you have multiple GPUs? If so, run FurMark in fullscreen, it will benchmark both cards if Crossfire is enabled.
My 2 GPUs also crash when trying to mine with a specific Algorithm, try using Nicehash and test different algorithms.
