Today randomly my miner got disconnected which has happened many times but after I closed it the bat file would not open anymore.
Not sure what the reason was but anyway I downloaded guiminer again and set up my bat file like
cgminer.exe --scrypt -o stratum+tcp://netcodepool.org:3333 -u xxxxx -p xxxx -d 0 -d 1 --thread-concurrency 8192 --shaders 2048 --intensity 13 --worksize 256 -g 2
I am running 2 7970s and before my gpu 0 got 750 khash and now for some reason it seems to bounce around the 600 range. Not sure how to fix it? I have my clock at 1080 and memory at 1500. I use catalyst to change my gpus and havent touched the settings.
Really frustrating even though its juyst 100 khash its still a pain. Please h elp me!
I had the same type of scenario happen to me a few months back.. I have a rig with 5x sapphire 7970's which all ran the settings you stated @ ~720kh.. Machine went down 1 night, I fired it up the next morning and it could not pull anymore than ~580kh per card.. The only way I got it back to ~700 (and still running to this day) was switching with -g 1 and TC of 20992 .. Not sure what happened to make these cards switch to start wanting a high TC instead of 2 gpu threads.
Goodluck!
