What software are you using for mining? I'm using spg-sgminer, and it's ~4.6Mh on Qubit
If you want to mine Qubit on AMD GCN and you run Windows 7, what you really want to do is running
M8M-376.
You might need to overwrite
presentation.js.
Seriously, the kernels included in sph-sgminer for Qubit are very far from efficient and pretty much the worse it could happen on AMD architecture.
I didnt know that, I've been using sgminer-sph as well.
