Hey all, been a long time since I have been here but I just upgraded from a 4GB GTX770 to a GTX1070! I am really pleased with the performance but noticed that the 1070 is running at a clock of 1189MHz, but it should be in the 1500 range. I checked the settings in NVidia control panel , and it shows power management mode is set to max performance, but not sure what else would cause my issue. Any ideas as to what may be causing my issue? Thanks in advance! 

Honestly i think your cpu is bottlenecking you. if you go to bottlenecker .com .  it show that cpu and gpu would have a 39.58% bottleneck. a second generation i5 is too weak for a gtx 1070 . just mt two cents. ive always matched my cpu and gpu when doing computer builds and have always had good luck
