How hard is it to get the Avalon to 32GHs, and what kind of power consumption am I looking at if I do that.
That's a good fricken question. Never tried to push them that hard. We have had 27GH/s from them max, but stability varies wildly between boards. At 27GH/s they were pulling more than 95w.
If I have time tomorrow i'll push a board to destruction and capture the results. Might give you an idea of the upper limits.
