"please wait patiently"  -   Is what they fail to understand that for every day that goes buy for me it becomes a greater risk that I will toast another PSU … The thing is, with the S4 I've noticed that if you don't reboot it every 4 or so days the hash rate stops dropping off. A warm reboot does not help … So I'm coming up on yet another period where I need to do a cold power cycle and sitting here wondering if the units are going to come back up is NOT fun… Its bad enough I have one unit totally down with zero compensation, I can't deal with having any more units out of the loop . If they run their cloud business like they run their hardware end I don't see a long future in both operations . I love the Bitmain product but the poor execution is KILLING them . Bitmain PLEASE give us a update ...

According to "Bitmain employee of the Year" dogie in his updated "no conflict of interest here" manufacturer trustworthiness guide - these are classed as "minor" problems, so obviously they are not too bothered about it. Their "please wait patiently" phrase is one of their favourites, ask any S2 owner, they've been "waiting patiently" for 9 weeks now......and still nothing 

I can't even begin to say how frustrated this makes me… I have had a bad power power supply and dead unit going on two weeks with NOTHING … No power supply , no refund of 10 mining days . and a dead s4 sitting in my rack …

yes I had a case open with bitmain providing them the pics of the burned PSU from day one…

I received this email this morning in reply to my email with .pdf of the original order.  Has everyone got the same?

Hi Sir,

I'm sorry that we were busy communicating with the PSU supplier these days and will make unified arrangements,
The good PSUs will be shipped out to the customers in succession from today, please wait patiently.

Can you PM me your order details, I'll get this checked.

That didn't work in my case, I attempted that twice. Absolutely had to reflash the SD card.

I'm rather disappointed. The compensation for those whose PSU died AFTER the announcement will not be given as per Bitmain's e-mail to me. This is pretty arbitrary. I wouldn't have minded so much if they had shipped the replacement PSUs already but to date I have not received any word of shipment. This would be the 4th day or so without mining and even if shipped today would be 5-6 days to reach me. This is very upsetting since my loss is the same regardless of when my PSU failed.

I'm not sure why it matters whether it died before the announcement or after the announcement. It's still a dead PSU not due to any fault of my own, it's still lost hashing time and there's still no word on the status of shipping out of my PSU. To address concerns of whether I was faking it just to get the compensation, I think the video I posted pretty much disproved it.

Quite upset at this and ruins what otherwise was a very nice gesture of Bitmain.

To anyone else that gets this, you can usually clear it by simply pressing and holding the reset button [on the LCD].

Well, I ordered my Batch 2 S4 from a reseller and it was part of the first Batch 2 still with the defective PSU. I found this out by opening it up and noticed no barcode on the PSU. I never even attempted to power it up because I knew the PSU is defective. My replacement PSU is on the way and it is my only S4, so glad that you brought this up. I am going to take the SD card out and make a image of it before i power it up with the new PSU, incase it ever fails.

On a side note, wish they would of test the PSU better. The defective PSU had no markings on it at all, looks like some generic PSU that they used/selected that probably took shortcuts to cut cost because there's no indication of any marking that it passed quality control or something similar.

This company's rating has been updated in the Manufacturer Trustworthiness thread.

[This message won't be monitored, discuss your concerns in the thread.]

That sucks, and I now feel your pain. I have no doubt that they will come through with both the replacement PSU and compensation, but a time frame or some sort of update from bitmain would be very appreciated by all affected, I'm sure.

I just fired off another email to them, I'll post if I get a reply.

I had the same issue with the power supply… that was over a week ago and still nothing from Bitmain… No 10 days mining credit and no word on when I will get my replacement PSU's

Very sad … I should be hashing at close to 8 THs but with one unit totally down its very depressing to see it just sit there .

Got a batch 2 S4 delivered today, and it killed my batch 1 S4 (no, not really but read on..)

So my batch 2 unit wouldn't work out of the box. The display was showing the IP as 127.0.0.1. After a bit of messing around, I figured the SD card was to blame and that a reflash was in order. Since bitmain doesn't offer a full image to download (why don't you, bitmain?), I had to power down my batch 1 S4, pull it's SD card, create an image from it, and flash that image to the new S4's card. Once that was done, the new batch 2 S4 worked as it should. I'm not sure why it didn't work in the first place, since bitmain had obviously tested it judging by the accumulated (very little) dust in the miner.

Now, for my B1 S4... About 30 seconds after the fans calmed down from their initial spin-up, I was treated to a smoke show like to other. A thick stream of Magic Smoke plumed out of the B1 S4's PSU for a good 10 seconds, before going out with an extremely LOUD pop. That loud pop was a short bad enough to trip the 30A 240V breaker that miner was connected to.

To add insult to injury, the event seems to have killed the on-board NIC on a PC that was connected to the same circuit, so that is also out of commission for now.

Alas, my dreams of hashing at 4TH/s went up in a plume of Magic Smoke. Hopefully bitmain will get a new PSU out to me soon, but I'm doubtful. I contacted them about replacing my PSU the day the offered replacements, but I haven't gotten an email back yet. Has anyone received their new PSU yet?

Fortunately I had another S4 to get an image from, if anyone runs into the same issue let me know and I'll upload the image.

You do realize that hash reported on Slush is a 60 minute average so it takes at least 60 minutes of mining to see your actual hash right?

You were right, the changes don't stick across a power cycle. Is there any way to make them permanent?

The only thing for it is a spike in external demand.

Like what happened in May 2013:

  With Cyprus banking crisis, Bitcoin hits record exchange values [...] up nearly 350 percent in the past two months, thanks largely to uncertainty in Europe's banking community.

and again in November 2013:

  The Motley Fool: A Very Bitcoin Thanksgiving - http://www.fool.com/investing/general/2013/11/28/a-very-bitcoin-thanksgiving.aspx
  Bitcoin price quadruples after Fed Chairman's supportive words (the "Bernanke bump") followed by a very positive congressional hearing on virtual currencies
 
The network difficulty increases have been amazingly flat lately.  Now if the price would just do a 4 or 5 banger, I'd be a very happy miner investor.

I too take ckolivas's view very seriously -- and have decided to convert some mining hardware back into bitcoins asap.  The btc price has taken a long slow dive this year, from last Thanksgiving's dizzying height's, and I do think the coin of the realm is now positioned to yield a lot more ROI than the machinery that digs them up out of the the dark depths of the mathematical coal mines...

thanks,

And thanks, Slush for your Facebook Cover Photo, that I see in my head now every time I think of "Bitcoin Miners"



Don't you just love these guys, and want to be them, with their hard work all over their dirty faces, and then want them to become just rich as hell?

I have my S4 oveclocked to 218.5 freq (that's the highest it will go without turning any o's into x's) so I've set my difficulty on Slush's pool set to 2250.  It still takes about 30 minutes to an hour for the pool website to show the worker as attaining its full speed hashrate > 2TH, but after that it stays consistently above 2.2 TH/s poolside.  Which is nice!  I've had it running like this for almost a week now.

Still not paying out that well, though, as Slush's pool luck has been pretty, um various lately :-)

And here lies the conundrum. Manufacturers ordered chips, hence they are committed to the product, but there is a lack of demand at low BTC prices.
Therefore, the only choice would be for manufacturers to deliver product to themselves into the data center.
However, they will then continue selling all bitcoin they mined to pay for ordered chips, facility, salaries, etc. Such selling would further depress bitcoin-and the viscious cycle continues.
How to get out of a cycle: you tell me, but I see only one possibility: closing down of many manufacturers operations.
Incidentally, how many Q3 mini-Neptunes at 1.5-1.7 TH for $3.5K was KNC able to sell? I bet the number is somewhere between zero and 100-200 (optimistically).

You have to remember that most manufacturers order chips in 6 or 7 figure quantities, so IF there is going to be a difficulty reduction then it takes time to propagate though - several months sometimes. That reduction / reduction in growth then gets hidden by the constant deployment so you never see the reduction in the first place.
