I'm fairly new to this so any help is greatly appreciated
I recently changed to an HD 5870 for mining and the first night I started mining I was getting fairly the right rate around 300-340 at intensities of 14-15. My problem is after I restarted my pc I noticed a change in its performance. I found out that it's no longer throttling to high performance. I get stuck mining at 600/900 clock speeds. So now I'm stuck at 200khash/s
Can anyone tell me whats wrong? Is my hardware broken? Do I just need to change settings on my miner? (I'm using guiminer)
