Sorry but never, i bought for 1550usd it wont make roi as well.
 SHITMAIN is changed their strategy , they wont sell any miner in limited numbers , so after 3 months all their miners will be obsolete.

Bitmain.com = 502 Bad Gateway

I've been having the hardest time getting their customer service to answer on whether or not my PSU that was ordered with the D3 miner has been shipped or not.

I got the D3 a week ago and keep getting shipping invoices for the D3 but nothing on the PSU, customer service gave a generalized auto response with link of how to check estimated shipping dates but the estimated shipping date has past.

Not very good customer service to say the least.   They never answer the phone and just give generalized responses via help desk.

from here system then update
load the file and update
 

Would you advise to apply this upgrade to all D3s, even if they have no issues ? 

I'm 4K into this...I'm at a 50% tax rate and have 25% equip ded

this year off full amount (usa) (instead of 5 yr depr) towards taxes I will owe. So I have some 'ego' cover....

So hell, I just need to get to 25% back on these 2 D3' about $1, 250 with psu's and shipping etc... to call it a 'draw' rather than pay the IRS/State Taxes and of

course equip deduction tax angle this year...

THAT almost looks unlikely as an EGO PROTECTION TOOL.... (which I need desperately)

could be rough running these long enough to even get the 25% back ..plus electricity

However, does not get around the fact that I did not fall for their  "Bitmain Toaster Fest"...hook line and Sinker..(the newbie lurks within it seems)

BTF: Bitmain Toaster Fest (I like it..I may use it as a personal meme)

ER ...wait must stay pissed off ...can't be distracted by meme's  (oh....look a cute kitty meme...awwww..)

Same issue.  My D3 arrived Monday but no shipment in sight for the psu.  I'm thinking of getting EVGA. 

Have same issue on one of my board, you try to run this one for some day but you will end with a halfboard working.

You have to send this one to bitmain for repair.

Send only defective hashboard, unplug all exept one (unplug power cable and connector)

Start this one, target defective, remove it.

Let run your D3 with 2 hashboard is ok, they gonna use 2/3 Watt so no extra charge, you just lost some profit.

Be sure to follow packaging recommandation and it will be ok.

Actually one of my hashboard is on repair
