What is the power to hex8?
From same psu like your hexb's?
Post clock and voltage pls
1.A Chieftec 450W PSU
2.Different - though I had no problems running my BFL Single from the 450W PSU and the HEXBs from the another PSU.
3.And this was my mistake. The technobit site says that "HEX8A1 defaults: --hexminer8-set-diff-to-one 0 --hexminer8-chip-mask 255 --hexminer8-voltage 1000 --hexminer8-options 8:260", but it didn't say that I have to specify these options, that if I do not specify them the miner does not work (for example, I do not have to specify any command line options for the hex-b to work).
