Ok, I have a problem I'm hoping I can address without sending back cards. I'm mining ETH with claymore's 9.5 miner.

I have "old" 1070s with Samsung memory that mine like champs. OC the memory through the roof and they just hum along.

I have "new" Micron 1070s that can't OC the memory as far, only about 550-575 on average and pull 29.5mhs or so. I'm fine with this.

I have "new" 1060s and 1070s with Samsung memory that can't mine with even stock clocks at all. A few minutes into mining they blue screen or crash the miner. I've tried using huge page files. I've tried using one card at a time plugged into the mother board. I've tried various motherboards and power supplies. I've tried different drivers. I simply cannot get these "new" Samsung cards to work. This is with both MSI and EVGA cards.

Thoughts?
