I am getting Hard Ware Issues when mining! Please help!

[yut.sin1301]

Hi there, My name is Gozzi แทงบอลเงินสด
Here is what my Run.bat folder looks like (I have windows, and a Radeon R9 270X):

sgminer -k groestlcoin -o stratum+tcp://grs.suprnova.cc:5544 -u BitsOfSteel.worker1 -p x  (my username on forums is BitsOfSteel, and I have my worker made and listed as worker1 with a password x

I am getting 5-7 MH/s however, within a minute I have 88HW issues, and none of my hashing was showing up online through supernovas website dashboard.

Thank you very much
