Yeah, it's probably a little less efficient overall - I mean - I'm getting 2/3 hash power, but I doubt that I'm getting 2/3 power use - probably a little higher than 2/3 power - making (TH/s)/KWh worse. But, agreed, probably not much difference. I think I may still be able to get it exchanged though. My supplier has been nearly impossible to reach, but I think it is due to Chinese New Year. I managed to get in contact with him since I posted. I have another question of him before shipping back - but waiting for him to come online again.

But, it has been a learning experience. I don't know about Bitmain - but like I said, PangolinMiner will not only snub you on the warranty - but even if willing to pay them to do repairs or pay them to buy a hash board - they simply will not respond. I could accept them not honoring the warranty - they state it on their web page, but not supporting customers who are willing to pay is BS! Pathetic business practices! I can't wait until Japan, the US, etc. have companies, who have some concept of customer service, come onto the scene. Whoever does it first with a good product will destroy crap companies like this!
