I've been having trouble getting cgminer to work... I can get reaper to mine LTC at faster speeds (still not as fast as it should be), however I prefer to use cgminer because it has many more features. Cgminer will mine bitcoins at proper speeds, getting over 2.5 Gh. However when I launch cgminer, I am stuck at really slow speeds (10-15Kh per core of a 5970).
5 BTC goes to anyone that can get me running at full speeds.
Specs:
Three 5970s & Two 5870s
Windows 7
Installed the latest version of AMD APP SDK & latest AMD drivers
Using 2 powered extenders and dummy plug resistors on all cards.
4Gb RAM (I tried up to 8Gb, but it made no difference)
What am I doing wrong? I've tried everything I can think of.
For your Two 5870.
cgminer --scrypt -w 256 -g 1 --thread-concurrency 8000 --intensity 16 --auto-fan --auto-gpu --gpu-engine 700-935,700-935, --gpu-memclock 1250,1250 --gpu-vddc 1.10,1.10 -o

Am currently pulling over 400Kh/s
This would also depend on your stock speeds as mine by default are 850/1200
you could play around with them speeds to see what you get out of it and am still playing with my settings. I maybe able to work upto 500Kh/s
This is using 4GB ram so shouldn't have any problems
