I believe there is a modded firmware floating around which fixes some of the issues with nwhash, wattage at the wall is ~1400W.
Dogie- Can they be under clocked maybe be taken down to 1.5 TH and Lower the wattage. I don't see any real information on this anywhere debating buying one since Bitmain is holding back on the S5s
Also what firmware version is running around for the nwhash issue. Can you at least point me in the right direction. Thanks
Yes they can be underclocked. Its not a bitmain firmware so its not officially recommended: https://bitcointalksearch.org/topic/cgminer-extranoncesubscribe-extension-binaries-available-for-download-850620
