I have found more info and it appears that I cannot use Claymore in Ubuntu to undervolt or control the GPU too much. All I can do is flash the bios and get a better hashrate. But if I was to switch over to Windows well then that is another story. I'd be able to use software to oc more and control more. I'm not sure if I want to change over since it is working now and I am not sure if using Windows will really give me a much better hashrate than I am getting now. Currently getting around 29.XX per GPU, but read can get about 30-33 in Windows. Is the extra hashrate going to make a big difference in mining?
