Hey guys, I was hoping you could help me figure out my problem. I've only been mining for about 2 weeks, so please bare with me.

I mined all last night on my 6850, getting around 215 kh/s with cgminer. This morning, I turned it off for an hour or so to do some web browsing, and when I turned it back on, I get 30 kh/s tops. I don't know what happened. I've tried changing the intensity (everything from 13-18) and I get no results. I've also tried mining different pools too.

Here are my current configs:
cgminer.exe --scrypt  -o stratum+tcp://doge.netcodepool.org:4094 -u username -p pw --worksize 256 --intensity 13 -g 2 --thread-concurrency 12160

setx GPU_MAX_ALLOC_PERCENT 100 in CMD
