Title: x6500 is far more stable with its own bitstream

After testing out the existing MMQ bitstream and the normal x6500 overclocker bitstream, the x6500 bitstream yields much more stable results. Far fewer HW errors across the board and hashrates within a few percent of expected right away.

I don't know the exact differences between the bitstreams, but, there is an obvious performance difference.
