Thank you for this guide.
Do you have a recommendation on make/model for the second fan in a double setup that would fit and also plug into the second unit?
Thanks again
you need a 120mm PWM fan capable of the highest airflow possible. at least 70CFM - the original is capable of >90CFM ---Additionally, the mounting holes are NOT the same size as case holes. you MUST use M3 nuts/bolts or rubber pull-through pegs as the typical screws that come with the fan will not fit. |

OK, so I have this... which is great... 1.) Although the nrate was 60, btcguild shows only 40. Any idea for that? 18 AIfDSo 49 2.176 1.913 152 0 0 0 0 181 [1:1] 618 9 9 9 9 10 10 10 10 10 10 10 10 9 9 9 9 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0

make sure you use the start-miner command or reboot after making changes to the best.cnf file. check your pool difficulty. if you are running 2 cards, your difficulty should be at least 64, but in some pools 128 will work a lot better. |

BITMAIN, for gods sake, please, put in a invoice in USD when shipping
and dont underdeclare it too much - put 2x the shipping cost at least
I agree, shipping electronics with too low a declared value only exacerbates the customs wait unless everything looks at least somewhat legit. sushi, could you add me to the paid list for my two units? Thanks. im not complaining that i paid <$30 in duties/taxes. if they put the full price, it would be >$300... |

Hmmm.. Only averaging ~10 gh now. I stuck a fan next to it.... I'm not sure what else to do.  what happens if you SSH to the system and type "nano /run/shm/.stat.log" and report back what you see. klondike_bar, If you (or anyone who understands what these logs mean) have time, please take a look at these. I've found my bitfurys are not performing like others I read about here and would like to get them working better. I've performed no mods. I just plugged them in and this is what I got. These are first batch US kits btw. Maybe I should do as you suggested to Trance but I'd like the feedback first. Thank you. If possible, shorten the lists to only the chips performing lower than 1.7GH, and it will be easier to spot the trend/problem. What batch is your hardware from? in the august/october stuff the hardware benefited from modding higher (not just speed but also getting low-performance chips to run correctly), but for the newer batch with higher voltage, issues will arise if you dont provide sufficient cooling (this means heatsinks AND airflow) I would suggest: buy a $10-15 multimeter and check the voltage on each card. Take the red positive signal from the top contact on the large cube-like inductor and the ground from the pci-e or screw terminal GND. You want a voltage around 0.77-0.82 if you have 'okay' cooling and 0.82-0.88 if you have relatively large heatsinks on each backside of the PCB, and lots of cool airflow In your case, the voltage on a lot of your cards seems low, almost like the august batch. check the voltage and if necessary, apply the pencil mod to increase it. If the voltage is high, then the issue is your cooling |

Hmmm.. Only averaging ~10 gh now. I stuck a fan next to it.... I'm not sure what else to do. what happens if you SSH to the system and type "nano /run/shm/.stat.log" and report back what you see. If you only have 10GH, its possible or likely that some or most of the chips got too hot and switched off. if this is the case you have 3 solutions: 1) more cooling and HEATSINKS 2) modify the miner.h file. to do this, SSH in and type: "cd /opt/bitfury/chainminer sudo pico miner.h" and then modify: max_error : from 5 to 6 (increases tolerance to errors slightly) min_good : from 50 to 40 (increases tolerance to low-performance slightly) max_speed : from 57 to 55 def_speed : from 55 to 53 min_speed : 52 [these options help prevent the system from switching chips off if they are borderline working] 3) modify the optimal settings to start the miner at a more managable speed. SSH and type: "nano /run/shm/.stat.log" change everything to AIfDSo 53 exit, and tell it to save as "opt/bitfury/best.cnf" |

sushi: please update the OP to remove the confusing december 4 date and also to indicate i have paid. thanks  |

Ordered the PSU and extension cables in anticipation of the shipping from the GB thread Little nervous about it all. Anyone ducted them yet to reduce the cooling? i just have a thick peice of paper sitting on top to keep the air from venting out the top |

Who is Bitmain and what is AntMiner?
I haven't really been following Bitmain. Maybe someone can explain how it is that they can spend a fortune to develop their own chips and then only sell a few units at a time. Certainly they should be flooding the market with their devices, no?
I don't know what it is but even though they are actually selling real devices, they still seem scammy to me. Are these really their own chips or just Bitfurys in disguise?
sushi would be able to say more; but heres my take. Bitmain is a chinese group that presumably opted to create a working ASIC device before making it public, so that they could show themselves as a team capable of delivery. I got the Antminer from the first auction, and it shipped very quick using an expedited UPS service. Build quality is better than i expected (see the reviews on the past few pages) and is possibly the best delivered product so far in terms of build quality ive seen (i have not actually seen a BFL firsthand, but those probably are the overall winner for cleanest looking device). The funding needed to produce just 30 or 100 units at a time is likely very high, and the first few batches are in effect the beta testing. I would expect some simple but effective changes to be made in later batches The chips are thier own. In terms of power-efficiency, they are middle-of-the-road, a little worse than bitfury or avalon chips running at the same speed. |

NOISE: C-
Weird that you say that, I wrote glowing comments about the noise level about my single blade s1 in my yet-unpublished-review. what fan speed and temps? my temps were around 43-48 and the fan was consistently around 4920RPM (listed) and at some points would rev over 5200 for a minute or so. Noise at 4900RPM is about equivalent to what id hear from a rack server, rather then a home PC. I run 2x230mm and 1*80mm fans for my bitfury at full 12V, and they are practically silent in comparison. I replaced the fan with a 120MM PWM 17.3dB 70.5CFM fan to compare, and the fan (listed max speed 1500rpm) was showing around 2200rpm and very quiet operation. however, the airflow was a little low so i was forced to attach the original fan on the far end with it pulling from the heatsink, and used a 7V adapter to force it to run at a lower speed. it is still as loud as a gaming computer if not louder, and i plan to exchange it with a second 120MM identical to the one i bought, as this should ensure full but silent airflow. I personally think it is simply a loud fan. whether theres something mechanically wrong with it or dust inside the bearings, it runs much louder than i feel it should or typically would for a fan its size. I am getting a second one from the groupbuy, and am interested to see whether the issue is the individual fan, or if im just being sensitive to the load whirr in the corner of the room Has anyone (including bitmain) creaated an enclosure for this system? I assume it would be quite simply to put one on the stable frame and improve the continuation of airflow across the unit - right now i have some paper CD wallets balanced on top to keep the airflow from escaping halfway and it does make an improvement |

I would at least appreciate some optimizations to the AntMiner port of cgminer, see below statistics of 2 Bitmain AntMiners running in a pool for 36 hours+:
Yea, its a real problem and personally the only negative thing I can say about the product. Unfortunately it's not just a cosmetic limitation... (Even noise, I mostly consider that a cosmetic limitation, at least for a >$1000 miner— we're not talking about a coffee warmer here ) but fortunately it should be easy to fix. do you have a loud unit? I found an almost silent 70CFM replacement, but it isnt quite as powerful as the one that came with the unit. (but a whisper compared to a roar) |

I boot up and the last lines read:
/dev/mmcblk0p2 contains a file system with errors, check forced
/dev/mmcblk0p2: Resize inode not valid.
/dev/mmcblk0p2: UNEXPECTED INCONSISTENCY; run fsck MANUALLY.
fsck died with exit status 4
failed (code 4)
[warn] the root filesystem is currently mounted in read-only mode. a maintenance shell will be started
give root password to log in:
your FS messup that why you cant boot up. f--k. figured as much. time to reload an image (i should back up my sd more often) back up and running, minus a few miner tweaks and a chainminer update |

picked mine up from UPS today (driver falt out lied about coming to my house yesterday, since i had a note on the door with simple instructions, and there wasnt even a delivery attempt sticker left behind *furious*), and havent plugged it in yet.
build quality is fantastic and shipping package excells (the metal frame tore small holes in the static bag, but thats the only 'damage'. Better than asicminer and bitfury in both regards
Glad that you finally received your gear, happy mining. Up and running. heres my brief review: packaging: A+ build quality: A (pci-e sockets would be nice, and the fan/heatsink setup could use some tweaks) ease of setup: B+ (fairly simple, but it could be made easier, such as the default gateway being 192.168.1.1 like 75% of people use) operation: A+ (stable running, 177GH average right now) NOISE: C- this unit is VERY loud. loud enough i am reconsidering my desire to buy another. The fan cools half the heatsink effectively, but the further half of the heatsink is simply having warm air blown across it. the exhaust air is warm-bordering-hot. I am sure that a slightly revised design with 2 fans blowing from above or both sides and being channelled outwards more effectively would allow a much quieter design. overall: B+ Bitmain delivered a working product and did a quality job of it. however, the cooling system leaves a lot to be worked on, and i hope some forum users post hacks or mods soon such as push/pull configurations or different orientations of the device. the mining status looks a bit odd though, am i correct to read this as a LOT of hardware errors and rejects?

so ive got the miner working on my own network, and can access it from my laptop via the router. however, it is not mining. what am i missing? all the pool credentials are entered and ive entered 3 pools just to make sure do i need to use the full versions of each pool address? ie: stratum+tcp://nl1.ghash.io:3334 instead of nl1.ghash.io:3334 or http://stratum.bitcoin.cz:3333 insead of stratum.bitcoin.cz:3333 ? EDIT: solved the problem. My router has issues with torrenting, and it seems that every time i torrent, i must reboot the router after or else it wreaks all sorts of havoc on my outgoing connections. antminer is functional! (and getting louder) |

Guys heads up on overclocking your AntMiner 202GH/s  that you? Im not surprised these can get 10%, from the sounds of it the fan isnt working/needed at full capacity often. (Mine is still with UPS, who basically failed to come today and no note was left |
