I'm going to solo mine BTC with my 9 GPUs, then I'll get the whole 25 BTC reward all for myself!!!  We thank you for your modest contribution to Global Warming....  |

My reward was also "cut in half".  I raised a ticket, and things will be sorted out as usual.  Yep 22106 was also half here.. email sent to support:) Regards M My payout was lower by 18% relatively to the proportional number of my shares. A possible explanation to this is a sudden rise in the pool hash rate towards the end of the block, which decreases the payout of all the other miners (but at the same time make a significant contribution to solving that block faster). Let's try to illustrate this with an example: The pool hash rate= 1800000 GH/s Your hash rate=200 GH/s your expected reward=0.002777778 BTC Now assume that Miner X joined the pool with 200000 GH/s a few minutes before the end of the block, due to Slush's 'anti-hopping' algorithm, Miner X's contribution receives almost full 'weight' despite occuring towards the end of the block, so the increased short-term hash rate at the end of the block is now 2000000 GH/s, your reward drops by 10% to 0.0025 BTC. This is not due to any 'fault' at Slush. Actually it might have been caused by a technical or other problem on one of the competing pools, which caused briefly a massive shift of miners to Slush as their 'backup pool'. Just my 2 mbtc. Enjoy the recent burst of solved blocks, which more than compensates for that 'disaster'... Cheers My understanding was that the calc, assuming you are mining at the time the block is found (you havent had a blip in providing hash rate etc) is my shares / pool shares * Block Value.. for a rough calc. (not deducting fees here) therefore for block 22106 :- 22106 2014-05-19 16:30:41 11:23:16 18010425802 3586935 0.00206705 301575 25.10258983 97 confirmations left which makes the calc 0.0049994 The three previous blocks using the same calc would have been :- 22105 I get 0.0048193 22104 I get 0.0049920 22103 I get 0.0049467 All very similar and in fact almost identical to what was paid out, as were the 4 blocks post 22106 Whilst I appreciate your point about another pool jumpin in, to halve the rate paid it would have had to be approx 1872607.589 Ghash/s jumping in.. approx the rate when the block was found I believe, to drop it 50% and the your shares / total shares dont give those values, and we have also had reports of people getting double payout on that block, so something is not quite right. This has been happening a lot since we moved to 60 minute averages, in fact one block, for me, dropped from .0048 as the calc to 0.0009 as the reward. Whilst I appreciate your suggestion, I think something more drastic happened in this case and may be symptomatic of other blocks like this in the recent past. I know it's not a huge issue, but when you only make 0.1 BTC a week (on average), it's a bigger deal Regards M PS dont get me wrong, I love the block count this weekend, and I love this pool, but if theres a possible issue, I think it's only fair to investigate to see what actually happened. Apologies, my theory was sound, however in this case Slush made compensation adjustments, and now my reward for 22106 is about 1% above my 'proportional share', which is within the common variance. I hope that your reward got fixed as well. Cheers |

Is someboby have teamviewer To make it for me ? I'm not able to set my configuration ?  I unplugged the antminer from the router than plug into my pc to setting up but nothing at all??? that's piss me off !!!! I hate network lol my email is neptune748@hotmail.comIf you run it 'stand-alone' between your PC and the Antminer, then you are no longer connected to the internet, so another person on Teamviewer can't help you. (And Teamviewer may pose a security risk). The connection between the Antminer and PC should be with a crossover Ethernet cable (unless you are lucky and there is auto switching on the LAN ports). The PC should be set for a static IP within the same subnet as your Antminer IP on the sticker. Don't be scared by this, see it as a puzzle/game/opportunity to learn. Read the guides again, follow them slowly step by step. Cheers |

Can somebody helped me with the configuration setting of my bitmain s1 antminer !!!! I follow all the steps and nothing work ?? and my miners don't beep ? Leave me your email and i'm gonna leave you my screenshot of ipconfig and some screenshot because here we can't leave some picture thank you guys !!!!! ps It's brand new I am very desapointed !!!! For screenshots you can place them on some free image hosting site such as http://imgur.com/, then in your posts here include a link to your image there. You should provide more information about what you did (what does 'all the steps' mean?). Can you reach your Ant through the web gui? To be 'on the safe side', you should connect to your Antminer S1 with wired ethernet cable. The WAN address of your Ant (written on the sticker on the front side, usually 192.168.1.99) should be within the address range supported by your router, but not conflicting with any existing devices (can't have 2 Ant's on the same address for example). If the previous sentence is incorrect, you can connect a standalone PC directly to your Antminer with a crossover Ethernet cable, set your PC temporarily to a fixed IP address in the same subnet, enter the Ant's address (192.168.1.99) into your browser's address, log in (default password is 'root'), go to the Network tab, change the WAN parameters to suit your router subnet and IP allocation (I left it with fixed IP), save & apply. Reconnect your ant to your normal network, router switch etc, so that it can reach the internet. It should now come up and start hashing into Bitmain's test pools. Log in to your Ant's WAN IP address (IP is the one on the sticker, unless you modified it in the previous step), go into Status, Miner Configuration, enter your pool information, save & apply, be patient while it re-configures itself, then monitor your hashing on the Status, Miner Status page. You need to click on the 'miner status' tab to refresh the page. The controller of the Ant is adequate for the task, but not super fast when making configuration changes, so you need to be patient. If it is really stuck, you can do a System Reset from the gui (again be patient, let each page load fully before hitting the next one, otherwise it would 'complain'). Good luck |

Jeez, 80+ PHs, where did all that new hardware came from!? Just when i though that the next difficulty increase would be around 15%, this happens  The last difficulty increase was 'just' 11% (from 8000872135 to 8853416309). Bitcoin mining hardware is becoming more affordable (example: Antminer S1), no wonder that this pool and others have significant increases to their hash rate (BTC guild will reach 10 PH soon, while we are looking at 2 PH).

anyone have specs antminer vs av16?
av16 is supposed to draw 4A at conservative settings and upto 6.5A at maximum safe settings per http://drillbitsystem.com/forum/index.php?topic=309.0. I estimate that a single board takes about 5-6A when doing 22 GH/sec. At 5A it will be 5*12=60W, so 22/60=0.367 GH/W. (probably need to add a few Watts for the essential fans). The Antminer S1 at default settings does 180 GH and takes 360W at the wall, which makes 0.5 GH/W. This suggests that the S1 is slightly more efficient, however both are significantly less efficient than the S2 or Spondoolies SP10. Cheers |

cool. ty so much. Guess this one is set up and hashing away... will set up the 2nd one when I get back home. Is there anything I need to look out for when setting the 2nd ant??? have not opened it yet but I'm assuming it has a different ip on the sticker? No, if it is a new one it will probably have the same fixed IP (192.168.1.99). The easiest way is to modify the one that you already have running (login to the web gui, Network tab, Interfaces tab (comes up first) then edit the WAN interface IP (IPv4 address box, change value from 192.168.1.99 to for example 192.168.1.98), click 'save & apply', then be patient as it takes a few minutes (if stuck do a System reset). If you try to run both S1's on the same WAN IP address you are looking for trouble. You also need to make sure that there are no IP address clashes with existing devices on your network (if your router has a feature to assign specific IP addresses, then use that to assign the S1's the same addresses as the fixed ones that you selected, this will prevent future clashes).

Hi guys. I'm new with mining, etc. I have seen lotta things teaching with the Gateway 192.168.1.x or 192.168.2.x If my S1 have labeled 192.168.1.x or 192.168.2.x and my gateway is 192.168.25.x how do I set up the S1 to mine normally ?? I need a little help with that. Sorry if it sounds like a very novice question or if it has been already responded. But thanks anyway. - BTC BTC BTCCheck out https://bitcointalk.org/index.php?topic=344970.0 or Dogie's guide https://bitcointalk.org/index.php?topic=355387.0. Basically you'll need to change the S1 WAN IP address to another static IP that is consistent with the address range/gateway of your router settings. If there is a clear conflict like in your case ("my gateway is 192.168.25.x"), and you cannot log into the web gui of S1 using the static IP address on the sticker, you can use a stand-alone PC which you temporarily configure to have the gateway that can connect to the S1, change the S1 configuration (log into the web gui, get into the Network tab, edit the WAN IP address to a different static IP address that is compatible with your network). Then you can connect the S1 to your network and continue with the other parameter settings as described in the guides. It's really easy, once you get familiar with the process it can be done in a few minutes. Cheers |

Good day to all miners, I purchased my first AntMiner S1 & got it work smoothly but my problem is I'm having a too high HW & more rejections.  Is this normal? or I'm having a misconfiguration? Any suggestions to lower my HW ratio? A rough calculation of HW error % is HW/Diffa/100, which in your case is 5598/1625824 = 0.344%. I don't think that this is something to be concerned about (nor is the 287 rejections over 1.6 million accepted shares). Somethings that may influence this: Check that all the hex head screws that hold the blade PCB's to the heatsinks are fully screwed in (don't over-tighten, but if they are loose, your thermal resistance may be too high). Add a 2nd fan in 'pull configuration' (any 12 cm fan will do, you can power it from the power supply used for the ants, or get a PWM fan with a 4 pin connector that you can attach to the unused fan connector on the 2nd blade. It's speed will not be reported but that's normal). Cheers |

(Somehow I don't think that a few Antminer U1/2's pose an interesting challenge to hackers.... ) Cheers Hey I've got 2 more coming :=_) BTW Here to learn not to make money ( YET }:> ) and that I'm doing Thanks for new info and fell free to correct my noob theories when not to lazy P.S. I'll try posting a bit less , but unless I don't ask answers are not given so bare with me plz Enjoy the various antminers (have quite a few U1's and 2's here...). I did not mean to discourage you from posting, nor to offend you - apologies if you need them. Had quite a few events here where the backup pool(s) came to be useful. You can also 'load balance' among a few pools as a way to reduce the variance (you may notice that Slush has some great luck days and some fairly low luck ones, if you spread your mining resources you might fill the 'holes', but at the same time chop down the tall peaks). Explore the possibilities of your mining software, it's part of the mining fun. Cheers |

Possibly some chips are not pinned correctly
thats the most unlikely thing. 1) reboot the unit. sometimes a reboot reads all the chips properly while using the PSU to power on/off causes initial voltage jumps and takes a second to charge all the capacitors. 2) check for anything damaged - primarily the capacitors. Its usually power related. I had a unit arrive on friday with a capacitor snapped off and when booting via PSU on/off it registers most of the chips as 'x' and/or marks them dead/missing. However, a reboot via the webUI causes the system to initiate will all 32 chips on that board working normally How do you explain the lower hashrate. You can have some x and full speed still. Poster did not indicate how unit was powered on and off. Also indicated psu was fine. Could be anything wrong, needs to test and narrow down possibilities. I never had any electronic component hardware faults on any of my S1's. The only issue that I found on a couple of them (especially on the last one received about a week ago) is that some of the screws holding the blade printed circuit boards to the heatsinks were not fully screwed in. I made it part of the normal set-up check list to go with an Allen wrench and gently tighten all those screws. In the worst case there was about 1 turn, but many had 1/4 turn or so (don't overdo it, just finger tight). A system restart sometimes cures the 'x's, especially if your PSU is marginal. Adding a second fan in 'pull' position and possibly small heatsinks on the blade ASIC IC's may also help with cooling. Cheers |

Mine was low to. But in my part my miners were redirected again right at the end of the round. So slushes antipool hopping code got me good. Is anyone elses bfgminer being redirected to the russian IP still. I was fine all week and got hit twice this weekend. My equipment is in a remote data room, running all BFL hardware. Good thing for API. Things I wound helpful was checking that slush is the only pool in the pool list , deleting bfgminer.conf and starting whole hing from BAT with SLush pool as only pool showing. Seems to me that then work was done you will get bogus block from slush just to try and stop pool hooping. What should happen is that once block is solved and no more new block are found all your miners should start working on bogus block just to make sure you stay on slush when it's dinner time  There is always Murphy's low , my computer went out yesterday and I only started mining this morning (there was an blackout with all the power in the house) so go figure  When you want to use another pool do the same thing , single BAT that will show your pool of choice as only pool (not active) buy only pool showing , when you want to go back to slush just use different bat and report results. It's not that well done in BFGMiner I must say and you still have to monitor from time to time that no new pool found it's way in but it can only do that through bfgminer.conf file.My theory is that when your miner sees no more mork on slush it hops to pirate pool. Anyway best of luck My BAT EXample : bfgminer -o http://stratum.bitcoin.cz:3333 -u Eagle92212.1 -p xxxxxxx -S antminer:all --set-device antminer:clock=x0981 Worked so far. However high speed workers are probably better targets. Running it from a BAT file does not offer any special protection. Using a single pool without fall-over to a back pool (or 2) ignores the sad history of pools having server faults (like the flood in Slush's place in Prague) or being victims of DDnOS attacks. It is a good idea to setup backup pools for such events, so that your mining resources are not left idle when your primary pool has some hiccup. You probably need to secure your computing setup at home first (good virus protection, firewalls, UPS, surge protection, password management, updates etc.). (Somehow I don't think that a few Antminer U1/2's pose an interesting challenge to hackers.... ) Cheers |

Slush Block #22025 that was "processing...." on the stats page got fixed, but the confirmed blocks did not flow to the confirmed reward, so payouts were missed in the last cycle. I hope this gets fixed soon.
Cheers

hmmm pool is doing something odd this morning.. last confirmed blocks reward not paid into confirmed... and last found block has been 'processing' for about 2 hours... even though there have been 12 confirmations...
Noticed this too. Such hiccups occurred some weeks ago and were always fixed eventually. Raised a ticked with Slush support, just in case they are not paying attention. Cheers |

have draw up rough plans for water based heatsinks for both side of the av16 board, sourcing a aluminum maker cnc, in talks with manufacturer
Unless you want to solve your particular cooling situation, you'd probably be better rewarded if you target something like the Antminer S1 or S2 with water cooling. As I see it, the main bottleneck in the near future will be efficiency in GH/Watt, as with rise of difficulty mining might stop being profitable if the electricity cost becomes greater than BTC reward. Unfortunately the Av16 boards are far from being efficiency champions (unlike the earlier Bitfury based Drillbit devices. I'll keep running mine while they can, but sadly just like BE's, they are approaching the 'departure lounge'.... Cheers |

Drilling holes might be risky, as you could bridge internal ground and power layers.
There's no drilling to be done in the PCB, there's holes pre-drilled and pre-finished in the PCB itself, so you'd only need to align some markings on the heat sink and drill through the heat sink itself. Then we could add some pressure to the connection with some bolts etc. (making sure of course that the thread on the bolt has a diameter smaller than the hole in the board) I've actually found the top of the chips get very hot as well so have been considering fashioning some kind of double sided heat sink either with an external clamp around the sides (so the sinks sandwich the board) or a second sink with another drilled set of holes in it. There is however a transistor that sits in the 4*4 chip grid that sits higher than the other chips, so some consideration for that would need to be taken into account before a secondary heat sink was applied. As a side note - regarding the separation issues I've noticed that the issue is likely from a lack of cleaning of the PCB from the factory before the heat sink was applied (I'm assuming the manufacturers did the heat sinking too) there was a fine black dust between the heat transfer pad and the PCB which was found after a heat sink came off and I cleaned the board with some alcohol. If you are using existing holes, then the risk is minimal. I have 4 of these Av16 Drillbit boards, which are stacked with the heatsink on top. So far I did not have any separation issues and they are working quite reliably. These are significantly less efficient than the older bitfury based boards and require plenty of cooling. I'm using 12 cm fans in push-pull from the sides, blowing air through the fins and also some old HDD cooler dual fans on top of each heatsink. This keeps it at a reasonable temp of about 47 deg C. Overcloocked to Av16:int:750:1:1000 they produce about 88 GH/s altogether. Cheers |

You could try to contact the seller through eBay, if he sold you a faulty item he should bear some responsibility. You may also try to contact Bitmain and check if they can provide or sell a replacement controller board. Good luck |

Hi jimrome, the temperature is lowered about 2 or 3 degrees, but in the interface Fan1 rpm is 2080 and Fan2 rpm is 0. The fan that I have added is PWM with rpm sensor but no rpm (zero) is showed in the interface.
W_M
This is normal, I have 3 S1's with an additional PWM fan in 'pull' position connected to the Ant's connector, none of them displays the rpm of the 2nd fan (would be nice if it did Cheers |

Does anyone know where I can get a bitmain S! Antiminer repaired? Seems one of the caps or something popped out approx 1/8 inch and now shows as dead. Or is it just a waste and for parts now? 1st one to go bad. If all else fails, there is RMA request: info@bitmaintech.com, assuming that it is still under warranty. Does the whole Antminer S1 appear to be dead? Are there any symptoms? You may want to post a photo or more detailed description of the suspect part. Cheers |
