I'm having an issue with the hash rate of my 970sc cards.  They're both only getting 3.15Mh a piece, and I am about exhausted of ideas as to why.  I have tried installing the 347.52 drivers, and when I install the cuda 8.0 (while doing a custom install to de-select drivers that over-ride the 347.52 ones), the miner will not run for me (says that no gpu's are found).  With the latest updated nvidia drivers I get the slow speed.  I am running win10...has anyone has similar issues with a 970?

Also, I tried using the v7.3 miner and get the same hash rate as with the v9.5 one.
