OK, first off I need to thank you for making this miner. It's giving me much better performance than DiabloMiner ,which for some reason was giving me less than 40 Million Hashes per second with two 5970's, using all four graphics cores.

However, I'm seeing a huge parade of invalid/stale results when I run the miner, with a few accepted results between them (About 80% of results are invalid/stale). I've tried down-clocking the cores (they are running at 625 MHz now), removing the -v option, removing the -f option, and decreasing the work-unit size. Nothing seems to have helped it much. ATIConfig reports all core temperatures below 70 Celsius. I'm mining with slush's pool.

Any ideas as to why this is happening?

EDIT: I tried using Deepbit instead of slush's pool, and all of the invalid/stale results are gone. Is this something to do with using slush's pool, or does the deepbit server work differently? They say that "no block confirmation is needed", but does that mean that I'm still submitting invalid blocks, and that they aren't checking them?

ANOTHER EDIT: Tried changing drivers to Catalyst 10.11, as I read that was more stable and reliable. I am using it with Stream SDK 2.1. Nothing doing.

UNLIMITED EDIT WORKS: Anyone know of a verification program that I can run to ensure that the OpenCL Libraries are installed correctly? I got the list program to run correctly and return all of the GPU cores, but I don't know if there is one that will tell me whether or not the calculations going on in the cores are valid.
