New cgminer giving low hash will tip for help!

[ccs5t]

I got a problem. My bat file randomly stopped opening so i downloaded guiminer and cgminer again. I made a new bat file but whenever I start it my GPU 0 bounces around the 600-650 range. I didn't change any of my gpu settings so I'm not sure whats up. Any idea? Before I had to download cgminer my gpu 0 was sitting at 750 khash. On settings 1080 clock and 1500 mem

I am running 2x7970s

Did you remember to put
setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECTS 1

at the start of your .bat?

It happened to me recently, too. I'm trying to sort it out but you can try this: http://sites.amd.com/us/game/downloads/Pages/catalyst-uninstall-utility.aspx It will remove all traces of the driver and then you can reinstall. You can also try a different kernel.

I've been seeing the big jumps whenever I run it with 2 threads. Changing it to 1 will lower the hashrate a tad but at least the main problem goes away.
