I couldn't go over 3000khs in scrypt, whatever the core frequency is.
I didn't test the BTC mode yet (I need to bring more power, I'm on the limit with my actual farm)
Power draw for LA3M in LTC mode only is 100W (including controller and USB hub).

I didn't flash the firmware of the modules. I'm not sure if I should do it, as the image provided in the archive is anyway from mid January.
I tried to do it, but I couldn't make the module connect on Windows (problem of drivers).

So far, I'm not very impressed with performance. I don't know how to get 4500khs as seen on other screenshot.
I'll update when/if I manage to flash the firmware of the units.
