I was hoping you would have an asking price!
Not sure the specs on those burnin boards.. Avalon Gen 1 eh?
You tell your price after seeing the specs.
Please note that the final stats are bit better than the below original spec per board:
TL;DL : 450Mhz [9Ghash/s] - STABLE
But at the cost of 94Watts of power.
Air:
431 - 54, 48, 1.30V, 87W, stable
450 - 56, 48, 1.30V, 90W, HW Errors
450 - 57, 52, 1.34V, 94W, slightly increased error rate compared to what i normally call "stable" but close enough
