I was batch 1
ordered 18 S3 miners
One S3 had 14 chips marked x and eventually -
I contacted bitmain via the new messaging system on their website and patiently awaited a reply for the next 7 days.
In the mean time another unit stopped hashing although I could view the web gui. Just no chains.. gone.... Fans at full tilt. Tried re-seating cables.. nope.
So, I took the control board out of the unit with the 14 dead chips and put it in the unit with no chains... Success, a functioning S3 again.
Contacting Bitmain on these forums I explained the situation as was directed to email them. Which I did, explained the whole ordeal and asked for advise on what to do with malfunctioning unit.
Flash new firmware was the reply, dont check keep settings. Failure. I informed them so. Silence...
Over my time I have made 24 seperate orders from BITMAIN totalling ~50BTC.
First time ive contacted them to say, "Hey, this ones broken".
Im not big on public outcries, however, on this forum-thread I note another member who had controller board problems and it wasnt until he made it public that action was received in the form of an RMA.
So, here I am
