No, you must have more or less 500 h/s in 1070 for Cryptonight, try to overclock/underclock and miner app must be tweaked eg. intensities, however, are you mining for profit? if yes, then you can check
http://whattomine.com on which profitable coin to their list, Cryptonight is not as profitable compared Zec for 1070.
Using the latest release ccminer, tweaking the miner app is some next level stuff that I've never even heard of lol. And no, I am just new coin hopping here and there as they get announced on the forum. What overclock/underclock settings do you recommend for the 1070?
From what You wrote I assume that You breaked Your OC settings. Sometimes card will go on +250cc, other times it won't go over +100cc. The key here is try and error. If you get such low hashrate's You could be over OC limit.
