Hi,
Rev B. dos not work with the boards u stated.
That's not correct:
I've boards here which have mounted such chips. Maybe it's not perfect to work on boards with Mr.Teals design, but it run and as I know these boards are the only one which support Rev. B chips (the ones with dark frame and bfl logo on top. I will post an foto of the chips tomorrow).
I've soldered not perfektly these chips on Mr.Teals board so not all engines will be run (80 - 100).
In this case the chips have only 24 - 30 GH/s netto rate running on one board of 8 chips.
But in the wild there many boards from Mr. Teal runs performant with rates from 32 to 40 GH/s.
At Lucko's boards (Mr. Teals design) I've send him my chips and these boards all runs more or less stable with the chips betwen 30 - 37 GH/s netto rate (measured at btcguild.com).
Or maybe I'm in mistake and the chips I've to sell are not Rev. B chips... The image will show it.
