5 antminer S1 units, cooled by a pair of Cougar 90cfm fans and running approx 460GH/430W (still working on tuning, 2 units are only running 70GH). Runs off a single CS650M
ps: temps are up around 60-65C, and the hardware seems fine with that. I plan to get it in a cooler location soon though to drop temps 5-10C
seems that the pencil mods increase in effect slightly over time, Ive had to adjust all my frequencies about 6-12MHz lower to minimize 'x' chips.
to that extent, I present the hex value for asic-freq frequency 187.5MHz ....... 0801 testing it right now to see how it works out
