Sorry, but with this kind of message it's impossible to help you or another people
Ok, you get 15Mhs, but you have to provide more information, I gave you a lot of tips, to update windows, drivers, miner, and you only post this? What you expect?

Post some pictures to describe your problem, tell us which version of card you have, OS, motherboard, miner etc ok
