I can do what I want, but you have to use facts not made up stuff. 1) Price has nothing to do with this guide, if its too expensive don't buy... 2) Underperforming, where? Every unit hits over the 2.0 selling mark. If not, then you're ignoring the instructions to use a manual difficulty of 2048. 3) Lack of support? They're the first company to actually hire a proper representative purely to increase communications. 4) Untested firmware releases? Engineers were getting heckled so much for a firmware update that they pushed an update with one file location wrong. It was fixed within a day, and within the meantime another member of staff had already shown the workaround. It only takes one look at your post history to see that you'll disagree with anything I say regardless, purely because one of the three pools listed you disagree with: https://bitcointalk.org/index.php?action=profile;u=371518;sa=showPosts1) I won't. 2) Wrong. Read the thread again. 3) Who's the proper rep? 4) Maybe if they tested the first release properly/at all they wouldn't get heckled. 1) Good, then you're just a heckler 2) Right, the only problem is PSU failures 3) Me? 4) I don't understand your problem... people were spam abusing them for not releasing an incremental update which doesn't do anything important at all, then flamed more when they had to either use a 2 minute workaround to flash it or had to wait another 24 hours. Why? But it doesn't matter anyway, you're not a customer. |

Yes lack of support. I think that you missed this post https://bitcointalk.org/index.php?topic=515448.msg9163035#msg9163035 It seems that the S2 firmware isn't up to date and all S2s are in danger of having their hashrate stolen. Don't judge entirely on the past actions, judge by the present actions. (like in AMs case where they are represented by not having preorders when they DO have preorders) No I've not missed it, I've replied about 10x to "where is S2 firmware" posts and get flamed every time I do for "spreading lies". Its coming when its coming, what do you want ME to do about it? If you want to include cgminer version in the chart then the vast majority of companies fail on that because most don't support what is considered a legacy product. |

I also think it is highly unlikely that a large number of consumer product will be available, as the whole bitcoin mining space is moving towards large farms.
And why do you say that farm products aren't also consumer products? As long as they maintain <3KW and 70dba, no reason why those two segments don't overlap. |

When will you be updating this guide to more accurately reflect Bitmains downward spiral since releasing the terribly overpriced & under performing S4, their lack of support & untested firmware releases?
Will your bosses let you do that?

Looks good Dogie. Did you get this unit direct from Rockminer? I haven't seen many in the wild.
Yes direct from Rockminer. They're sold in minimums of 10 via Rockminer, but there are plenty of resellers about - even on Amazon. |

Updated to the new firmware -- everything works great!
For people wondering when you go to update/flash the new firmware -- select the entire .tar.gz file using the webgui.
One thing I noticed is when rackmounting -- the screws for the rackmount ears stick out too much (when sliding into the rack you'll need to force it in) and sometimes the screw holes don't align with the ear bracket. You need to unscrew the top, reseat it so the holes line up, then screw the ears on.
Has anyone gotten decent results with overclocking?
I have a couple units that are only averaging 1.75TH/s on ghash, while my others get between 2.0 - 2.4 average. Any ideas on how to get the low performers up to regular hash rate?
Can you upload a screenshot of your slot unit |

But now they're charging $135 (USD) for UPS shipping. Such Wow not. They are charging me £214 for my S3 delivery to the UK + the import duty + VAT @ 20% I know I cant compete in mining BTC which I why I have stuck with the alt coins and trading them like mad to earn BTC. I can see the end is nigh for me mining, this will be the last batch of miners for me. With now crazy prices and DOA miners from the last batch of S3's I bought it's time to get out  Are you sure? When I add a pair of S3's to cart for UK it gives me: 0.65 via DHL or ~0.42 via UPS. That should be £144 or £92. The import duty is usually £7 via UPS or DHL and is paid regardless if you order a box of air or a box of diamonds - its a handling charge. The VAT @ 20% is charged by the government and is nothing to do with Bitmain. I added 3 to the cart and delivery via DHL was 0.948 BTC. I've bought over a dozen S1's and S3's and normally only in pairs, each time VAT/import duty was between £80 and £180 for each pair. In a few cases the $ value Bitmain put for the item was higher much than the actual BTC $ value so I ended up paying more (only happened on 2 deliveries). Got my shipping info but still gutted I ended up with 3 and not the planned 5 S3's I was hoping for. Would be useful to get Bitmain to put on the S3 product listing that delivery is extra. As I said, UPS is about 60% of the price for UK - choose that option. |

As of 10/10/2014 - this is the firmware listed on the bitmain support site:
initramfs.bin.SD-20141003.tar.gz
Do I unpack it or just point the S4 at the tar.gz and it uploads and decompresses it
and deals with the whole thing?
Thx.
Unless bitmain has gotten around to uploading the working firmware, you'll need to use this: The latest firmware on the site is the fixed one, I just tried it and it flashed fine. https://bitmaintech.com/support.htm?pid=00720140930114518599JXGHWWD80660 |

If you want to avoid VAT, you can host your miners with Bitmain on checkout. Also avoids delivery.
How does that work, please? Is it a viable option? What if you later decide you want the machines delivered after all? Cheers. On checkout there are two delivery types, there is some information you can read there. |

Doesn't help in the EU anyway, you have to pay VAT whether you are importing goods or buying them locally.
Unless you are VAT registered. Then you can reclaim the VAT paid, and there is no VAT due on mining revenue [In the UK at least]. This isn't the reason I'm VAT registered, its just a side effect.According to my accountant and HMRC you cannot claim VAT back on mining machines UNLESS you are buying them in to resell. The simple version of the rule is that you can't claim an input unless it generates an output, which because as you say there is no tax due on bitcoins mined or sold means you can't claim it back on the hardware used to produce them, this also means that you cannot claim the VAT portion of your electric bill either. If your accountant says different it might be worth clarifying which position is correct, as you are no doubt aware errors made in regards to tax are not treated lightly here. Every bitcoin miner is bought and later sold. What happens between it being bought and sold. Mining happens in between. But anyway, that's also not how VAT works. You can reclaim VAT back [with exceptions] on goods and services purchased for business activities. In the same way you buy a stapler for your desk - you don't have to be putting that stapler into stock for resale. The same applies for electricity - is it a business expense? If yes, you can reclaim the VAT on that portion of the bill [its only 5% so negligible really]. Regarding the argument that it didn't produce an output, well, it did. That output just happens to be not applicable to VAT. |

Hi everyone, Just wanted to ask for some advice if possible. From reading through the forums i assume that http://ck.kolivas.org/apps/cgminer/antminer/s3/4.6.1-141009/cgminer has the updated cgminer for the S3 & S4 machines. I updated one of my troubled S3 Machines last night, and the pool hash rate has gone up slightly, Is it advisable to flash all my machines (24 S3s and 1x S4) I also have 3 S2 machines that have a really outdated version, Would it also work for these machines too, Any advice is appreciated. I'm not sure what that string is in relation to Bitmain's string. It won't work for S2, that firmware isn't ready yet. |

I want to see the day a manufacturer decides to make miners in EU or US will sell lots more miners as they will be
more atractive to buyers...but guess have to wait until I get used to
There already were/are manufacturers, they ended up being scammers or failing miserably due to poor business practices or just having terrible customer services. Doesn't help in the EU anyway, you have to pay VAT whether you are importing goods or buying them locally. Unless you are VAT registered. Then you can reclaim the VAT paid, and there is no VAT due on mining revenue [In the UK at least]. This isn't the reason I'm VAT registered, its just a side effect.Yes you can reclaim it but you still have to PAY it. And most people aren't VAT registered as a business. If you want to avoid VAT, you can host your miners with Bitmain on checkout. Also avoids delivery. |

Antminer L1? That's not shipping until December.

I just got my batch 2 S4. It had no cgminer at all.
Flashing the firmware was an easy fix. Still I don't understand why there is a QC passed sticker on the miner.
What do you mean it had no cgminer? I assume you meant it said "cgminer not started", which means your configuration settings were wrong. |

I'm only speculating here but access to Hong Kong from Shenzhen might be restricted right now.
.... Absolutely 0 chance of that [regarding the protests]. |
