Where is competition ?

/r/bitcoin had a link to this story I read last night, https://bitcoinmagazine.com/articles/the-unknown-giant-a-first-look-inside-bw-one-of-china-s-oldest-and-largest-miners-1444675310

"We will also be offering the 14nm chip in a miner for consumers"

Apparently they are working on a 14nm chip, so that's something we can hope they will actually sell to individuals. I am not familiar with them and I don't find google translate does a good enough job when researching them on .cn sites.

Who all is still waiting on B1 miners?

My B1 order from 9/5 has not been shipped. Or if it has, I have no tracking info.

No answer to my emails to Bitmain either. I've don't even bother with their support system because it's never been effective for me.

Hello to BitMain Support,

We have been a very Loyal Customer of yours and referred countless people to buy direct from you.

I had recently on 10-11-2015 created a support ticket to get the refund
of my over 4BTC you have held for parts swaps.

You had received all the parts back many many months ago.

I do not know where to post this so I am starting here.


Please research my support Ticket:
Refund of my Deposits:
ID:#4148


I'm sure it will take a little time to do your research to verify all the sent information.
Please respond to verify you are looking into this matter.


Most Sincerely,
MikeMike

Isn't BW the same as LKETC who made a shitload of Dragon miners back in the day? They're not new although the 14nm thing could well be vaporware. The Dragon was based on a 28nm chip made by someone else so it's hard to believe how they suddenly have the ability to make a 14nm one.

Anyway, on topic, at approximately ~0.027 BTC per day our compensation after 3 days should be around $20 per S7.

I just read the article, although I know nothing about them outside of the article.

Yay, I have $180 so far that will likely be taxed in creative ways to reduce it further. \o/

I just noticed that my hash boards are labeled 600M, which I'll go ahead and assume means they've been tested to work properly at 600 MHz.



Can people who have received units with stock clocks of 575MHz confirm my theory? Also, for the few of you who received a unit before bitmin's time off, could you verify if you have a sticker at all? I'd guess there isn't one.

[philipma1957]

i will check my s-7 in the morning.

mine has been in house for three weeks.

[UfoRia]

Farck, they are checking every single hashing board manually and labeling them post-pressing? This is generally accepted as the reason test pressings are part of a QA\QC process before bulk production with anything in the semi-conductor industry.

Even though I am agitated beyond belief waiting for my nine s7's, from an IT perspective I feel sorry for the poor employees having to test the boards. Shortcuts are a gamble, they just crapped out and their employees are manually testing each board due to skipping test presses in the fabrication process.

Sigh!

i don't have anything on mine (B1 S7)-pre golden week shipping.

[Prelude]

Cool, you must have one of the first public ones. I've got  feeling you won't have stickers.

Have I mentioned how much I like the S7 so far?






Some quick stats:

625MHz = 1220w DC (From PSU) 1300w AC (From WALL) 5015 gh/s 12.05v at hash board
650MHz = 1267w DC (From PSU) 1352w AC (From WALL) 5220 gh/s 12.05v at hash board

Next stop, 675MHz.

congrats, you seem to have a very fast machine, although when I tried 612 on mine it briefly went to 5000, but then slowly went down to 4915 over 12 hr and i decided not to bother. I have high ambient (28-30C) and at 612 boards were already at ~56C.

Yeah, seems like I definitely got a good one. Ambient is about 20c right now, so that helps a bunch. Running 675MHz now, averaging 5260. Not much gain over 650MHz, looks like I've hit the point of diminishing returns.

Mine does not have m 600 so the m600 is like a quality inspection pass

Well, that about confirms it. Now we just need someone with a default clock speed of 575 M to chime in.

my batch two should do just that.

[UfoRia]

my batch two should do just that.

Please don't take this the wrong way, but a large number of people haven't received their B1 orders. The fact you did receive your order, happily mining away and postulating on your excitement of your B2 order while others receive no response from phone calls or emails from Bitmain on B1 orders is aggravating. Granted, I am in that group sitting on a $20k order with no communication or "concrete updates", so I apologize for pointing out my own frustration.

On a personal front, I apologize for being an antagonist in this thread and I am not singling you out by any means. I don't speak Chinese, so my only outlet is this farcking thread....

edit:

I know there are likely tons of people that have received their orders and don't bother posting after they get their gear. I get that dynamic, I just wish I was in that group, so call it jealousy.

Hi,

Does my S7 already shipped? Can I have the Tracking No. from DHL? Patiently waiting more than a month now.

Thanks,

Mine also got the 600M sticker! I decided to break warranty on one of my units, and ran a 625Mhz clock all night. The avg. result was worse than stock-clock, 4,7X TH/s.
The variable is this: When I overclocked, I configured the fan to run at 100%, this put the temp on the hashing boards at 30-35C. I actually believe this might be the reason for the poor results, they seem to thrive at higher temperatures.
