About that power issue, I was informed that it was measured on LTC . The problem is not the pool you're using but the current difficulty and coin type. The higher the difficulty the more power the machine needs. Early gridseeds had exactly the same issue , having different power draw depending on the coin you're mining. I was also assured that if you have a faulty hardware you can return it and have it refunded, so I'm sorry but I don't see an issue here. I also fail to see a connection with them and BFL. They said they'll deliver and they did, if you got the hardware a day or 2 later, there is really no issue, most online stores reserve at least a week for this. And as I said before you can return the hardware if you want. As for your time, imagine you go to a store, buy something, come back home and don't like it, go back to return and request money for your lost time  Are you serious? Then why is my Falcon pulling 1100 Watts from the wall for mining CGA with stabilized diff of 2 and net hashrate of 180-200MH?? Big difference than the HUGE difficulty of LTC..... Say what? You own a Falcon. And its running at 180-200MHz? wtf? I'll clarify. CGA net hashrate is 180-200MH/s. Going to be testing starcoin with net hash of 50MH/s to see what power draw is for a REALLY low diff coin. Any less net hashrate than that runs risk of 51% from my asic. my falcon does 24-28MH, btw. waiting to see if they release promised patch before I decide to return it or not. A) I believe you own a falcon. B) I believe you when you post numbers like 1100 watts C) My guess if all coins will mine at a 950 to 1150 watt number in the 24mh-28mh range . which at best would be 33 watts an mh. please tell me the make and model of your psu. I have a 1300 watt evga psu gold rating a stud psu . If you have an equal let us know. You may have a poor qualit psu which would account for as much as 100 of those 1100 watts. you may have a high watt pc setup which would be 40 or 50 extra watts. but it seems to me at best you are going to get to is 900 plus watts. for the falcon alone. I am in the process of getting more gridseed blades . I may go to 5 of them. that would be close to an exact match of your falcon. we can point the gear at the same pool. say wemineltc ltc only and see if you do 1000-1100 watts for 28mh and if I do 420 watts for 26mh |

look this is simple enough. if you purchased and think you are cheated send the gear in and get a refund. For me I hesitated on all the new gear. I never purchased anything from gaw but gridseeds.. Had some hitches which they fixed. In fact they sent a batch of old gridseed 5 chip units which were dead. They gave me a store credit and i purchased a members only ant miner s-1 for 299 usd minus the 250 credit. came new and mines fine. Then the shit hit the fan. For me as a dedicated miner Zeus gear seems to pull 30-40 watts an mh. while gridseed blades pull 16-18 watts an mh on a plat psu. Since they cost close to the same in dollar per mh . for now I am picking gridseed blades. I did order this from gaw today as it is good gear for blades http://www.gawminers.com/6-pin-pcie-to-3-x-2-1mm-barrel-tip-power-cable/ my advice if you are buying gear to mine in your house buy a gridseed blade from zoomhash. buy the power cable from gawminers. use a plat psu to power the gear.

I have never done anything like this, so a few questions from a newb:
1. My understanding that for undervolting as per bitmain scheme, I will be removing R3, etc. resistors, but then instructions are a bit thin for me…Do I put something else in place? bitmain says: refer to resistor value to replace. This is where I don't understand. I have to replace R3 and 7 other resistors (8 total, 4 on each board) with what?
2. how POTs came into this? Is it a POT I have to put in place of removed resistors, or is it optional and I can simply put a small droplet of tin where resistor (R3, etc) was?
Thanks
Yes remove the R3, R66, R38 & R52 resistors from each blade. Either replace these removed resistors with new resistors of the value Bitmain has given (3.24Kohm for 102.4Ghash or 4.02Kohm for 115.2Ghash). Alternatively instead of putting in the fixed value resistors (3.24 or 4.02) put in a 0 to 10Kohm adjustable resistors (POT) (this is what is shown on the pictures attached a page or two back). With the POTs you can undervolt, go back to stock, or if you are brave overvolt with no more hardware changes! Trends Where do you buy these POTs? thanks [/quote] mouser/newark/jameco a few others. Since I may be wrong about the 5k the 10k pot may be better here is a link for a low cost 10k pot http://www.mouser.com/ProductDetail/Bourns/3306F-1-103/?qs=sGAEpiMZZMtC25l1F4XBU9QhtPcWQTANAkX0QUL%2f5Dw%3dplease check with others but I think this is good. |

All you need is a pencil and a multimeter, and about 10-15 minutes per antminer. (a 4B pencil is a bit easier to work with than a 2B/HB since its softer lead). Its not as precise a method as actually soldering a new resistor, but its ~95% as effective and far faster and less likely to do permentant amage then using a soldering iron to remove/replace a SMALL resistor Is pencil mod even stable or you have to constantly monitor the ant's power usage/HW mistakes and re-mod every week or two? my pencil mod is 11 days old 3 ants do 430gh at 563 watts. rock solid for 11 days. |

If you ever wanted to get back to "stock 180GH" your pot would have to go up to 8.2Kohms which puts you at 1.12 -1.13 V at the chip.
5K ohm will only get you up to 0.9 to 0.92 V at the chip.
0- 10K are just as common as 0-5K and both are priced the same at $0.40 - $0.70ea
If you're going to play, play right.
my oem resistors were all 4.46k so a 5k pot should work |

my followup is here I should run about 630gh here are my numbers for 2 days or so. these include under and over 1ph at bitminter and are pretty much spot on. they merge 4 antminer s-1's 1 in my home clocked to 200gh-------------cablevision middle speed internet option 3 in my friends office clocked to 430gh ------ verizion hi speed dsl all on the same workername at bitminter . so bitminter is screening and merging two different internet services in two different cities correctly. NICE WORK DOC! The server can handle a few hundred thousand more connections with no problem. There are fewer connections and fewer people/workers mining than in a very long time.
All Bitminter servers have hardware suitable for the job they do. Configurations, including Linux kernel parameters, have been tweaked to run well with the hardware in use and to handle high loads.
I never said higher bitcoin difficulty should mean that your hashrate is reduced. Your hashrate is unaffected.
Other miners are not seeing the problem you have. See for example what philipma1957 just posted.
When we reached 1 PH/s the load on the server was lower, not higher, than before.
Now imagine on your gaming server you had 10 000 people playing and everything is fine. Later, with no changes to hardware or software, you have 5 000 people playing and one of them is having a problem. If your conclusion is that this one person has a problem because your game cannot handle 5 000 people playing, then your conclusion is probably wrong.
The web server estimates your hashrate based only on accepted work. The most common reasons that you would see a lower hashrate on the web server than your actual hashrate is rejected work or hardware errors. Since you are not getting much rejected work, have you checked how much is lost due to hardware errors?
or we are now under 1ph and numbers are 420-430 on the underside of that number. the only major under reporting issue your pool has ever had for me was red fury usb sticks. they consistently went too low. other then that all your numbers have been fine. I mined with you only from aug 2012 until nov 2013. In nov 2013 I finally was able to teach myself cgminer bfgminer cpuminer along with ltc mining and I now mix mining with you cex.io btcguild and wemineltc. You pool seems as good as any. It also is very newbie friendly. I tell you what. I have another antminer s-1 on btcguild. I will move it to bitminter. this one is in my house and is clocked to 200gh see photo this is a more difficult test for the Doc's server. the 3 at my friends place of business are at 420gh and are on a verizon modem dsl. my 200gh is on a cablevision modem one is Lakewood NJ USA one is Howell NJ USA.. All gear is pointed at the Doc's pool all have the same worker name in my account. I was at 420-430gh I should go to 620-630-gh see second photo I do. I will post again in a day to show long numbers not just 10 minutes.  and here you go 630 gh using 4 ant miner s-1's . 3 set on underclocking total 430 gh (Lakewood, NJ USA) verizon dsl hi speed 1 set on overclocking 200gh (Howell , NJ USA) cablevision mid speed  |

Yeah, I don't want to test the higher end. Mine are at 4.47 (give or take) currently. I'll only be in the 4.47k to 3.2k range  or lower... edit... I'm a dumbass... 5K pots turned all the way up are going to result in too low resistance to hit the lower voltages? 0k to 5k pot is common to find. my guess is cranked to 5k you could achieve 220gh at 450- 460 watts on a good plat psu with extra cooling. while lowered to 3k you can do 140gh at 175 watts>>> i did this one one of mine. I would love for all my s-1's to have a 0k to 5k pot or better yet a 2.5k to 5k dial in option. 2.5k would prevent too low and 5k would prevent too high |

I Just ordered from gawminers this is a very good product that they sell I had a store credit and purchased this from them http://www.gawminers.com/6-pin-pcie-to-3-x-2-1mm-barrel-tip-power-cable/If they ever decide to carry gridseed blades again I will order gridseed blades from them. For now I order gridseed blades from zoomhash. As of right now I only recommend gridseed products for asic mining of scrypt coins in your own home. Due to power and safety issues. Sad that gawminers has had these problems. I hope it gets fixed for those that purchased the newer gear from them. Note gawminers hosting service appears to be okay if you use a cc and get a 60 or more day return policy |

I have 2- 5 gpu mining rigs, 3- 60gh/s BFL Miners, 2- 10 gh/s BFL Miners and about to hook up my antminer s1. The one gpu mining rig is powered by a evga 1300, and the other is powered by a cx750 and a rm750 and the bfl miners have the power bricks. My question is that i have them all in my basement but i have to run extension cords to different outlets so everything isnt on the same circuit cause i was having a problem with it blowing the breaker. I only have 110v power. I was thinking about installing a 220v outlet but i was wondering will a 220v outlet be able to handle more power then a 110? Also will my psu be able to run on the 220 or do i need different psus? The 3 60gh/s bfl power bricks have a 110/220 switch on them but my psu dont have a switch. How many watts can i run on 1 220v outlet(if it possible to figure out)? I know how to install a new breaker and what not but i have no idea what the limits would be. Any information would be greatly appreciated!
you do know that your bfl gear is very power hungry? 1 ant miner s-1 has the exact same hash power as all your bfl gear combined. Have you considered selling the bfl gear? and using the money to buy an s-1 miner? The power savings would be big. Those power bricks use a lot of power and are not very efficient. Oh as for putting in a 220 volt line it would be okay as long as it is cheap. If your electrical service can do 220 (you need the proper wires coming in) and the cost is under 200usd go for it. And with a 100 amp breaker your home maxes out at 9000-9600 watts total for 24/7/365 use. 120 volts x 100 amps = 12000 watts peak safety factor is 75 or 80% of that or 9000-9600 watts |

A gridseed blade cost 699 hashses at 5.2mh 3x 699 = 2197 power draw is 3 x 83 watts = 249 watts hash is 3x 5.2mh = 15.6 mh use a platinum psu like this http://www.amazon.com/Antec-EA-650-Platinum-Power-Supply/dp/B0064LWI40/ref=sr_1_6?ie=UTF8&qid=1401536889&sr=8-6&keywords=antec+psu105 usd buy 2 of these a great product from gawminers cost 22 dollars http://www.gawminers.com/cart.php?suggest=5389c1b41250eyour total cost is 2225 safe stable runs cool power draw of 249 watts or buy the black widow from gaw miners 1799 http://www.gawminers.com/the-black-widow-13-mh-s-asic-scrypt-miner-week-three-with-free-zencontroller/ get 13mh draw about 400-430 watts buy the same power supply from amazon 105 the power cables at 12 get 13mh at 1916usd with 400-430 watts used and the gear from the youtube video sounded pretty loud but it is a youtube video factor out all the delivery issues. why i have caught the usps and dhl with bad scans many times with many companies. factor out the power plugs---------------the 6 pin 8 pin foul-up you are left with this fact: these new rigs are power hungry compared to gridseed blades. but a little cheaperat best GAW miners was deceived about the power issues and did not realize it until they were shipped. I am being nice….. So you got gear that is using almost 2x the power that a gridseed blade uses. Is simply means you need to figure out the power cost. To decide if they are worth the current asking price. If you do not understand how to decide what is the better value a gridseed blade is a at 699 usd or a black widow at 1799 usd. Ask an accountant. Or some one that can do the break down price wise. For me in my home I will use 3 gridseed blades not a black widow. I spent a little more upfront. about 300-400 usd more I have to deal with more wires . I have more hash 15.9mh vs 13mhs I spend less power 250 watts vs 400 watts I think I run quieter not sure. I think in the long run my choice is better then getting the black widow. but if you want to be hosted the widow or the falcon may be better then the blades. |

Added link to my pictures of the 10k pot addition to S1's. http://imgur.com/a/8SUO8 It would be best if you are going to just change out the resistor to put in a 10K pots! Then when BTC is worth $1000 or so you can just crank the S1 back up to 200Gh without more hardware changes. You could do a side business s-1 mods. you need coins to drift upwards at the correct pace. |

my rma came today… I got a chance to install it and it seems to be working at about 5.2mh I will ship it( the bad blade) back via usps priority mail. I could not get to post office today ,but should get to it on sat. I am awaiting the tracking for order # 5663 I paid for it on the 29th of may. I am considering purchasing 1 more maybe on sat or sun. I have a question about my zoompoints I have 46000 of them which means i spent more then 4600 usd in you store. When do you think this program will come back I would like to buy something with all these points. Thanks again for an advance cross shipment on the rma. To all those that doubt the post office is fucked up look at my rma tracking. now zoomhash told me they purchased label and shipped late may 27th. they are in California I am in New Jersey the item arrived this morning 10:30 east coast time if you look at the post office paper trail they never scanned anything and fucked up everything, but the Howell NJ end of the shipment. This happens a lot and here is good proof it happened. Good proof the USPS was wrong not ZOOMHASH about sending a timely rma.  |

they could put the resistors in and sell the modded ones as s-1A's
low power model.
better yet they could put in 8 pots 3k ohm to 4.47k ohm and sell them as adjustable models
ones with pots would be great - I would like to see them release a more compact 'S1A' with slightly smaller heatsinks closer together and an initial 150GH/200W spec. This could drop the costs slightly and handle the first small undervolting step for the consumer I don't believe they will come out with such an exclusive run down version of Ant S1. I'm waiting for their new generation hardware announcement. depends how far off the next gen is. If its still a month or two away it may serve bitmain well to release a slightly undervolted version of the S1 in order to keep competitive in poth price and efficiency. I 'know' i cna undervolt my antminers when the time comes (very soon), but i really dont look forwards to repeating the process 16 times... well if coins creep past 700 usd undervolting gets put off a month. |

well maybe the firmware will drop watts to a better number. but 2x the watts of a gridseed at equal hash is not good.
I am disappointed as I wanted to buy some of them. I am happy I got an antminer s-1 from them when they sent me a credit last week.

Both GAW and Zeus have updated the Power Consumption. Falcon is now at 1040?  ? That is not going to fly. 5 gridseed blades = 1 falcon hash wise watt wise the gridseed blades use half the watts not good for this new product. |

Hey guys well I am in need of some advice on who to go to. A friend of mine told me about this whole bitcoin thing and said that my warehouse that I own would be good for this sort of mining (I store my personal things there but would be interested in using part of the space for the miners).
As of now what I have planed out is a T1 internet for the warehouse and all the proper ventilation needed.(Will be hiring a local expert in that scene if I need fixing). My only question for this community is which miners should I be sticking with and what will be the best bet for the bucks. I am willing to lay down around 3.2 Million of my spare savings into this and see where it goes. I have bought 13 bitmain 180 GH/s Miners and it was able to convince me to get the 1 th/s machines. I no longer will be using those as my main focus is just using only 1th/s setups.
Please give me some feedbacks on what you have used and what you think would be the best investment in for it.
I will play nice and say one thing what does power cost you? If you are under 8 cents a k watt . I will say how much power do you have? If you say you have a 240 line with 400 amp service I will say offer a hosting service. |

What about calculating in the increase of hardware errors? The overclock is actually more efficient: 300 = 12.0MH/s @ 473w (39.4 watts per MH) 328 = 13.5MH/s @ 512w (37.9 watts per MH) 360 = 15.5MH/s @ 568w (36.6 watts per MH) Edit: Tests performed with an 850W 80+ Bronze PSU. Bumped my Black Widow clocks to 360 and I'm now getting 15.5MH/s. More HW errors and power consumption went up of course...
Did you do a side by side to compare efficiency? Make sure the OC is worth it  Man those numbers are high. I am doing 10mh at 167 watts on 2 gridseed blades and 1 gridseed 5 chip . and one of the gridseed blades is defective . I should be doing 11.0mh but I have a 1200 watt plat seasonic which is more efficient then your psu. still you are 3.4x the power for 1.5 x the hash Something is wrong with the firmware these miner should be at much lower numbers. I am doing 16.7 watts an mh with the gridseeds |

I am curious...EVGA has 8 PCIe cables. Are they split cables or did you use split extenders to run 5 (10 connectors) underclocked? What is the box? Is it some kind of datacenter box or something simpler? I am intrigued. The evga came with two split and two single i "borrowed" two split from another psu. so yes i used split cables. edit : the box is a corsair. all undervolted and on undervolted s-1's the split cables do not over heat. running 4 or 5 undervolted down clocked on the evga is the most cost effective method if you are power restricted. I run 4 on the evga in a friends office space. he splits his power bill 4 ways so it is not 16 cents a k-watt it is 4 cents a k-watt. I am getting 560 gh and 730 watts with fans at 1400 rpm and temps at 40c. I only wish he could spare more power then the 730 watts I am using. |
