Can you give values for higher hashrates?
I'm currently running mine steady @ 2.6 (4c81) with HW=0, just wanting to see if I could push it just a bit more.

(2.8 (4d81) is too much, the miner doesn't start)
What sort of black magic did you cast on these things to get it up that high? I can barely run one of them at x0981 (2 GHS) with 0 HW errors and the other at x0881 because if I bump the lower one up, I get mad HW errors, and if I bump the other one up to x0A81, I get about a shit ton of hardware errors...
