You're doing fine,
the only other thing to do is to have the slowest/most error prone card as last one in each bank, and from the numbers it seems it already is like this.
Try to put all the cards/chips at the same speed, I've found it is more stable than having speed differences between cards.
spiccioli
Glad to hear I'm not doing anything stupidly wrong. As for getting all the cards/chips at the same speed you mean actual hashing rate or the clockrate in the miner's best.cnf file? I currently have those card overclocked a bit. I tried to get them as close as possible to 1.70 ohm on the R02 resistor. It's a pain in the ass to do and there is no precise method so this results in some cards being pushed harder than others. Now as far as clockrate in the miner's conf file I tried my best to have them running at the highest clockrate that is possible without the chips producing too many errors but this once again is a bit tricky. Sometimes the chips run fine at a particular frequency for a long time and produce low errors and after some time they crap their pants and start producing errors. Like I've been saying all along I find bitfury gear finicky and not as robust as it really should be. But that is just my opinion. yeah, its definitely not robust equipment. its a beautiful and elegant design, but its not remotely robust Ive actually got my fastest card as the 3rd/last slot in my first bank, since it was the original from the starter kit with biggest heatsinks that prevented it from going anything but last in a bank. its still doing 37-38GH while the rest run at 33-35GH |

Yeah, slush seems to be limping along for me now. Others are reporting problems though. Definitely smells like something is up (coordinated DDoS?).
ghash.io appears fully functional... |

I wonder how the possibility of counterfeiting these coins is going to be cooked in their market value of time.
How does one prove that the coin for sale is an absolute original unless it somehow was graded BEFORE the august announcement of counterfeit coins in circulation??
I keep the original documentation showing the original owner but how can even that be trusted?
history on bitcointalk  make the/all sales public. Personally, I have a PGP-signed message from Mike, plus all original packing including the casascius-stamped shipping box. The coins themselves would also be quite difficult, though not impossible, to counterfeit; same with holograms. |

Yep, 2.2 on their site and I have paid 2.65 for one that has not even shipped yet!!!!  "We created a myth in bitcoin community: no pre-orders, shipping on time, even pre- shipping. We are earning more and more trust from worldwide customers." how long will that last if you make a firesale and then sell the items cheaper a few days later?? So please Bitmain, answer your emails and give us all our "unshipped" Ants for 2.2 BTC When did you order the 2.65BTC units? It makes sense that they ship a few days after the small fire-sale batch (if/assuming they are a different batch run). The 2.2 BTC units wont ship until sometime next week, close to the weekend. In other news, my 2.4BTC unit is running today, and I passed the 1TH mark for my farm |

PROBLEM : NOT HASHING
I disconnected briefly from the modem and on reconnecting all my bitmain systems returned to hashing normally but the bitfury does not.
I can access 192.168.1.249 and click 'start miner' but nothing happens. '0 GH' refreshes time to time
I can SSH in and see that no chips are running at all.
Pool settings were not altered whatsoever - nonetheless i re-saved them and still nothing
whats going on? Usually the system bounces right back from any brief internet outtages/disconnections

I think about two options:
a) sell antminer to sb (in Warsaw - any offers?)
b) buy another PSU.
How do you think?
Option 3: Plug a computer drive like CD/DVD or HD to a free wire. Your problem is, that the psu found to much watt suck at the PCI-E wire and turn off. With use a drive it shall work properly. if this works, your PSU is severely outdated. every PSU ive used recently is fine with providing 12V current only, as long as you follow the labels for how many watts and rails there are for the 12V signal |

I must warn you all about my experience, so keep in mind that info and order at your own risk. I'll keep you posted if you interested in this situation and how it will finally ends. Here is my original message that is now also a part of the ticket on sushi-review.com Well, i don't like to whine, but here is my experience that i want to share.
First i ordered two units on 10 dec for 4.25 btc, and i can't receive package because of local ups/customs asking additional docs that i can't obtain, so miners likely to be sended back (or even destroyed!) Sushi stated, that they can be a subject of china high import fees if returned. So now they are like "schrodinger's miners" between russia and china customs and i don't know yet if that 8.5btc would return to me at least partially, not even to say about ROI.
Second, i ordered on 25 dec another 2 miners for 3.15 btc from this GB with hosting option to partially compensate previous fail. Now i think that it was the second fail in a row, as hosting still not started! I already trying to communicate with sushi, and last reply regarding this question was on 7 jan where he asks me to supply pool/worker info (i re-sended the email with that info 3 times already, still no reply and no workers connected to the pool!).
In general, i understand that in the first case he sended units in time and customs issues is out of his responsibility. But it would be good if he at least try to offer some kind of workaround, as all benefits of early shipping is lost with the price of 4.25 btc per unit that is still not received. And current situation with hosting is only makes the things worse.
Here is their reply Hi, thank you for letting us know the situation. Unfortunately, we have no control over your country's customs action. You can send it back to China if you'd like but you must pay the return shipping fee. As Antminer was sold as NO REFUND, we can't issue you the refund but offer an option to be hosted. There will be no refund on customs related delay or intercepted packages, however, if it was returned to China, we will place your antminer on our hosting plan. (0.60 BTC per miner for 3 months) We will fight with Chinese Customs to lower the import tax as much as we could, but if it's expensive then we will ask you if you want to pay that or be destroyed. Future discount wise, we will provide some discount on future hosting plan purchases as we will not send you any more miners until you resolve your country's customs issues. Even we give you a discounted antminer, if it get held in the customs it will be a waste. We checked if Sushi processed your order in timely manner and it showed payment was received and shipping instruction was received and your Antminer were sent on time, but your country's law stopped UPS from delivering them to you. This is out of our control and it's something we can be responsible for. But if there are additional documents that we can provide, please let us know. We receive a lot of request for fake invoice, fake letters, fake website, fake Paypal transactions and that are something we CAN NOT do to get Antminer pass the customs.
With best regards,
Customer Service
It sounds like it may not be BITMAINs fault if your country refused to release the miners to you. It also doesnt sound like its your fault though. *that said, if it was refused because the value of it was not correct (BITMAIN listed very low values on the first few rounds of sales before making full-price markings optional), then the issue could be seen as their fault for placing an incorrect price. What was the rule/law that caused the customs issue? |

modified server psus are great too: $5 for the psu and $10 at home depot, and Ive converted a 835W Power Supply that has 4*12V and 4*GND lines - 14AWG each for an Antminer and a 7-card bitfury
Hey what are the efficiency ratings of these PSUs? Thanks Not a clue! Over on the modified server PSU thread though it sounds like basically all server PSUs are designed for >85 or 90% efficiencies since all they do is produce huge amounts of reliable 12V power |

It's probably going to be a pain in the ass, but the easiest way to do this is to connect the miner to the router via ethernet cable, login to the router on your computer, get the ip address from the router, and put the ip address into your browser.
Can you log into the miner that way?
When the miner is hooked up to the router, I have no problem logging in, through the browser. I have all of my settings, but then I get this error: Wed Jan 15 20:25:27 2014 daemon.info sysinit: ntpd: bad address '3.openwrt.pool.ntp.org' Wed Jan 15 20:25:27 2014 daemon.info sysinit: ntpd: could not resolve peer 3.openwrt.pool.ntp.org, skipping Wed Jan 15 20:25:57 2014 daemon.info sysinit: ntpd: bad address '2.openwrt.pool.ntp.org' Wed Jan 15 20:25:57 2014 daemon.info sysinit: ntpd: could not resolve peer 2.openwrt.pool.ntp.org, skipping Wed Jan 15 20:26:27 2014 daemon.info sysinit: ntpd: bad address '1.openwrt.pool.ntp.org' Wed Jan 15 20:26:27 2014 daemon.info sysinit: ntpd: could not resolve peer 1.openwrt.pool.ntp.org, skipping Wed Jan 15 20:26:57 2014 daemon.info sysinit: ntpd: bad address '0.openwrt.pool.ntp.org' Wed Jan 15 20:26:57 2014 daemon.info sysinit: ntpd: could not resolve peer 0.openwrt.pool.ntp.org, skipping Wed Jan 15 20:27:01 2014 cron.info crond[576]: crond: USER root pid 3633 cmd /usr/bin/cgminer-monitor Wed Jan 15 20:27:03 2014 daemon.info sysinit: Alarm clock I went to the troubleshoot and attempted to use those 4 addresses. I still get those errors. When it is hooked up to the computer, it gives that previous error, when i put the miner address in the browser. Black screen and those letters. this should be emphasised in the how-to, as it seems to be mandatory rather than optional |

I had the same problem when I forgot to add "Custom DNS server" in WAN setup. CGminer couldnt connect to internet. I use google 8.8.8.8 pool info looks okay, try the DNS 8.8.8.8 as suggested. thats likely the issue |
|
|

your pools (miner configuration) are not correct - the log shows it skipping between all 3 unsuccessfully dont include any 'stratum+tcp' or 'http' in the address, and put the port in the proper column. can you screenshot the pool config page if its still not working? |

Well OK.. I even tried to get more watts out of the ide drive cables but no help. Thanks.
that wont help you. find a power supply with a single 12V rail thats got at least 500W minimum on it - kijiji or craigslist is a good place to look found a 800W, (700W on 12V single rail), FULLY modular (even the 24-pin) Ultra X3 PSU for only $40 BNIB local - 4 PCI-e ports on it for power Hey man! You don't need to have ASIC wannabe in your profile anymore!! Just said I'd let you know  haha, maybe ill change that once the antminer arrives and i pass the fabled 1TH/s mark (should be 1.05TH in fact!) |

Please watch out this website is very buggy - I made payment right away and Bitmain says only needs 1 confirmation
Had 10 by 30mins still website not show I paid now my order has been canceled and yet I paid with over now 15 confirmations!
Trying to get a reply from Bitmain or his email team is near impossible.
Sadly I now fear the worst :/ Anyone else had this problem ?
don't fear the worst - the bitmain team is one of the best and most legit. Remember, its the middle of the night in china so they likely are not watching emails closely |

bringing this up again: Delta DPS-835AB, Artesyn 7001138-Y000, IBM x3650 3655 835W (12.1V 69A) Power Supply
at 835W, these units turn on with a simple pin shorting (pins 3 and 4 - which are easy to bend into contact and place a small solder bead across) and have large, well-spaced sockets that can either be filled with wire leads and solder, or have the outer plastic snipped away to expose the metal contacts. I converted a unit with about 20min, some AWG14 leads, and a few different sizes of heat shrink (1 size for the leads and 1 size to seal off the entire terminal to any accidental contact or shorting). I plan to post some pictures shortly, but right now its doing an excellent job of powering a 7-card bitfury system usin 2+ and 2- power lines that experience no warmth. It will also power an antminer shortly, either using 1+ and 1- per blade (pushing it a bit) or 4 wires to one blade and a seperate PSU for the other http://www.rcgroups.com/forums/showthread.php?t=1766215 |

Bitmain just dropped their prices to 2.2 BTC for 180 GH/s. Dave, don't let them get away with all the orders. Time to drop the prices again!
to be competitive, an H-board (lets assume it CAN go 30GH without much trouble) will have to be around 2.2/6 = 0.4 BTC (assume a little extra because of the power efficiency) right now at ~0.5BTC each they could use a slight drop further  |

Good news To hose who say 2.2BTC is too high, you need to review your calculations - difficulty is beginning to settle a little towards 20% increase per jump which results much differently than those 96%/month estimations. I think that at 2.2BTC, you should expect it to mine 2.1-2.6BTC in its useful lifetime I have units from the original 4.75 and 4.25 auctions/group buys, and looking at the income they have provided, they have made *approximately* 4.3 and 3.95 BTC each - a little lower than bitmain's estimate, perhaps because shipping time/delays and system setup/down time were not factored in. - In either case, both systems need to pay off far less than 2.2BTC of their costs The product is simple and fairly energy-efficient. it would be nice to see an option added to purchase units with a secondary fan installed, or perhaps slightly quieter fans, Considering I have added a second $20 PWM fan on each unit ive bought so far Super http://bitcoinwisdom.com/bitcoin/difficultyMy estimate is around 35% Second please let some who participated in those group buys to comment reality against projectionBy reality I mean separate pool/s account and the ACTUAL TRACEABLE income Have in mind that in reality mining income is at least 5% less iff all is super fine during the period and you do not need calc for that maybe you missed what i said - the 4.75BTC unit IS very close to paying for itself. I run at 190GH and $0.10/kWh. Its not as close as bitmian is suggesting, but i had delays in shipping, setup, and some internet outtages. In either case, I expect the miner to pay for itself sometime around, or just after, the next difficulty jump in 9 days its a little tricky to estimate the exact income, since i now have 3 antminers and a bitfury mining together. All mining is a single wallet address, and I have used a few pools (eligius, btcguild, and ghash.io) at different times and sometimes sent payments from them to btc-e or to bitmain for purchases rather than into the mining address - so I have to round some numbers and make a few estimates on these details. PS: I am using Cougar 120mm PWM fans (<21db, 70cfm) as my secondary fans, and i beleive they help pull a lot of the excess heat away |

Before I added this AntMiner, I was running 4 BFL units off a netbook. The netbook has an ethernet port and a wireless adapter. Is there any way that I can connect the Antminer to my wireless network through my netbook? I'm not sure if it would be more reliable, but this would solve my current problem.
assuming you get an internet link through the ethernet, you should be able to use windows to 'bridge' the connections. to do so: go to network settings page where it shows all the connections (should show lan, wireless, any usb modems, etc) click/highlight both the wired and wireless that you want to bridge, and right click -> bridge connections this should push the internet connection through the netbook to share with the bridged device. I have something similar in my network right now since my cable line is down for a few days (and 800GH of equipment needs a connection!) cell Phone- tethered via USB - USB port - Bridged with wired connection - ethernet to router's WAN - router provides LAN to equipment the only issue is that the bridging does not let me visit the ip addresses of equipment on the router. to do this, i use the computer's wifi to connect to the router and thus see all other connected devices. |

For me WiFi issue was solved. Switched WAN to DHCP and after reboot miner uses WiFi. Credit goes to mwax321 , Hi guys i'm stuck with WiFi settings  I've created WWAN interface with WiFi in "Client" mode and enabled DHCP. Assigned it to firewall zone wan. Once i power on Ant with unattached ethernet cable, i can see in my router console that Ant connected via WiFi and has IP 192.168.1.95, but nothing works (ssh/ping/Luci webpage). If I attach ethernet after few seconds it's recognized by router with default ip 192.168.1.99. Then everything works from both IPs (ssh/ping/Luci webpage) If i simply deattach ethernet, it falls down again, BUT if i first stop WAN interface from console, Ant switches to WWAN, and works perfectly. i checked iptables and it seems that for each wan interface the same rule was added for wlan0. Do i need to add static routes or something else? I had your EXACT same problem (even the same static IP .99 lol) and I found out the solution: - Ensure your WiFi settings are 100% correct
- Edit the WAN settings to use DCHP instead of static IP. So now wireless and LAN are BOTH setup for DCHP
- Restart without lan cable plugged in, and within 2-3 min it should start mining.
This worked for me. I'm not sure why this works, but it works. It could be that it's re-writing the full config file again, and if this is the case, you can later revert the WAN settings back to static. I haven't tried this to confirm the ACTUAL problem. I only found the solution. Are you able to log into the miner using the IP that the router assigns it? so this is working? I have another antminer coming today and have run out of wired ports so would like to do wireless so long as its not impairing the hashing process |

Mining Stably, Delivering on Time, if not Pre-Shipped. Now we need only 1 confirmation after you paid the bitcoin. As we will double check before we finally ship, We believe double spending attack is not rationale. 2.2BTC/Unit, Shipping included. The first batch of Antminer buyer is going to ROI in a day when I write this postWhen Bitmain first introduce the miners on the market, we sell on 2013/11/23 a 180GH/s ANTMINER at 4.75 BTC. some people fear the increasing of difficulty, while some other community members bought it. What if these miners started to mine on 2013/11/25, how many coins has the S1 mined, assuming not overclocked, 0.10$/KWH, 836USD/BTC? The number is 4.697BTC, electricity bill deducted. The miner who bought S1 on 2013/11/23 @4.75BTC per unit needs only another day to enjoy the ROI when we write this post, without overclocking.Now according to our model, which has been proved accurate or conservative in the past, we believe the 2.2BTC is profitable price for the miners, and a fair price to distribute the future mining revenue between the Bitmain and the mining community. Good news To hose who say 2.2BTC is too high, you need to review your calculations - difficulty is beginning to settle a little towards 20% increase per jump which results much differently than those 96%/month estimations.
