Probably will not be able to get 1000mhz ...
This is simply just not true.
I have 14 5830s, and 12 are running at 1020/300. 1 is at 995 and the other is at 1000.
I hate this lol!! i feel like im so close.. If this wont budge then I might have to install windows and use RBE to do something to make this run faster in ubuntu
