Hey guys. I have 4 280x running on phm sgminer 4.1 Yesterday I had about 8.2MH/s and I had to restart it this morning and now I'm getting only 7.3MH/s I can't seem to get it back to what it was. Anyone happen to know what I am doing wrong? Thank you.
With 4 280x, you should be squeezing 8.75 MH/s. Delete the bin file in sgminer directory, apply the following config and reboot (reboot mandatory to reset in your case).

The GPUs farthest from the CPU can be overclocked the highest, of course play with the settings.
