Anyone know how to force the fans to run all the time independently of temperature?
Try --avalon-fan 100, if it revs down. Try --avalon-fan 0 instead. Thanks, I tried both - 0 seems to spin the Fan2 @ '240' and Fan3 @ '480'. The other miners show '2880' for both fans. Any ideas on how to make these fans go all the time? Maybe starts form value 20 not 0 and it could be reverse so 80 is 20% fan speed. After setting value give it minute or 2 to setup. https://en.bitcoin.it/wiki/Avalon--avalon-fan <arg> Set fanspeed percentage for avalon, single value or range (default: 20-100) I have a unit that works reverse: --avalon-fan 80 = 20% fan speed if i put value 20 it's 80% fan speed. other units --avalon-fan 20 = 20% fan speed |

Here are my stats. Getting between 183 - 195 GH. I tried bumping up the frequency but the error count goes too high so it looks like this will be my hashrate unless there is some other tuning I can do.
Are all the chips hashing in cgminer api log. Half speed is 5 chips cold. Zero hashing is all 10 chips cold. Quality issues if some chips are cold from start.  |

Ordered 14 units on 1/9, received 7 yesterday and expect 7 more today. I highly recommend taking these apart and checking for loose wires and screws. I'm pretty sure they dropped these into their boxes from 6 feet up and then threw a handful of screws in afterwards.
All 7 units came online and 6 of them hash above 200GH/s with one hashing at ~180GH/s. One of them seems to have trouble keeping the fans going and it keeps overheating - which is frustrating. I've tried using the --avalon-fan 20-80 setting without success. The fans seem to just stop until the unit gets super hot and then come online for a minute or two and then stop again. Here's a pic. Click it to hear the noise on youtube.
Very cool setup there. I'm with you on the packing and screws. All my units have had loose screws in parcel. Check your cgminer api log from there you can see if all chips are hashing. Half the speed means 5 chips are cold. 5 Cold chips in blade unit. I will try to bypass fuses maybe tomorrow. This is old picture i didnt take the unit apart today.  |

I could tip .1btc if someone would like to fix that through teamviewer. I would give more but I spent all my btc's in that rig  I also had trouble with the wifi, pools were switching to failover, connection lost at random moments etc. Suppose you can't use it without wifi? It should work fine then. I actually bought an extra LAN switch for the miners, before I received them. Read from this thread, that the onboard wifi wouldn't work correctly, but tried it anyway  The problem was with the power consumption I think, ethernet card and wifi together would draw more power, than the control board is able to supply. If you setup wifi it will only work after you unplug the ethernet cable --> TPlink will route to the wifi and connect pools OK You cannot access the WebUI configuration page over wifi or it wont answer to ping. Doesnt matter if you setup wifi in LAN firewall or WAN side of firewall. WebUI is protected from wifi side in firewall settings of TPlink. IF you dont know this much i suggest DO NOT GO MESS WITH THEM. Do not enable disable things you dont know. You will lose access to your unit like some ppl in here did. Here are setup pictures. My units are in private network so IP range is 10.x.x.x firewalled  My LAN is setup with static IP 10.250.1.202 which i can use and config the Unit. gateway 10.250.1.1 private DNS server 10.250.1.1 you should use 8.8.8.8 it's googles DNS will always work if gateway is correct. My wifi is connected to private wifi (about 1500$ Cisco industrial lap station) wifi is setup with DHCP so the IP comes from there. Once i pull off the ethernet cable the TPlink will automatically switch to wifi and the unit will keep hashing over wifi. But like told in this thread before TPlink wifi is highly unstable and will failover alot, you will lose hashing power. I do not know if units some are diffrent, but i dont trust the wifi. I did testing for 8 hours and i constantly kept hearing from fans how the unit did lose connection to the pool also this was seen from hashing power in the pool. Like previously suggested in this thread if you must use wifi you should get wifi-gaming adapter and connect the wifi trough ethernet port. This wifi is not stable.     Today i did some PSU upgrading with 1200w FSP Aurum single rail psus. Now this unit got 2400w worth 12v total 200A. Time to put in some torture testing. Outside temp is here is -19c today btw         |

so I am stuck with a bad setup for my wifi connection. I can access the interface without problem, but I can't apply change to cgminer. I've got Applying changes Loading /etc/config/cgminer with the wheel rolling forever... Is that a port problem ? can anyone help ? Someone was talking about a teamviewer help, that'd be super cool That will keep rolling forever if you setup pool server for CGminer and dont have working internet connection settings. working Gateway working DNS cgminer will try to connect the pool but fails and wont startup. you have to powercycle the unit, check you internet connection settings then try cgminer setup again. if yo u get that wheel rolling forever again your internet connection settings fail. ---> Fix internet first. |

10-12 days seems about on par with what's been happening lately.
Can anyone confirm or deny if I should just trash the included PSU's in the US?
They are 170-230Vac you need 220v connection for them. See pictures few pages back. |

Our engineer says its controll unit problem
il send you a new controller unit and pbu , express delivery today.
Awesome, thanks for your responsiveness! That kind of response is a good sign - please keep us in the loop with this. I'm thinking of getting another avalon clone and not so sure btmine is up to producing any more for me than the one unit I have (and like). Same deal i got +1TH/s BTmine and i want more. Also we need some spare parts aka blades i suspect some chips dying. BTmine might stop with Avalon after CNY holidays. I only need parts 2 blades + tplink and control board. This diyu case is easy to make. So make these parts available cheap. I can assembly the units myself. |

1) Sorry, I should have described the location better, but perhaps you don't have any modules with FUSE1 silk-screened? All but one of mine did, but I think I got an early version. I did not take pics, but using another user's pics I'll point out where that single fuse is on his dual-fuse (newer?) version. Top left component right next to far left large capacitor, the fuses in parallel which don't seem to be a problem (so far) are marked with a single "P". At that same location on the boards with FUSE1, there will be a single FUSE1 fuse, with two other small components just below it. Hope that helps.
Thanks man! I was waiting this info. I just replaced 2x stock psu with two Thermaltake 850w 70A single rail psu and overclocked to 1500. i will do shorting of thoes fuses tomorrow. Two Thermaltake 850w with 5 cold chips not hashing 1400 stock 878w 1500 OC 947w it's hashing 222.64 GH/s to BTCGuild with 5 cold chips. Temps are no issue my location is cold. |

That machine is damaged??  It's not. Blade unit was loose but undamaged as it was nicely stuck with other heatsink. Avalon chips are other side of that heatsink they were fine and undamaged. Only Case was bend the fan is eaven working OK. This case is really soft material it wont need much of a hit to bend like that. DHL had something to hit the parcel. Material cost for this miner is very low.. that psu is 30$ in China. Case is worth 5-15$. Chinese can make this with 400$ once Avalon price goes down. I just used hand force to pull the case somewhat straight and propelly fixed the blades. The unit as good as new and hashing ok stock speed for few hours. |

Good day. Another shipment of miners arrived. Yet again they took some beting from DHL. This unit is still hashing away 220GH/s it's like a drug... need more miners-    Stock PSU 170Vac-240Vac  |

Check the PWM cable. Color should be Black/Red/Yellow/Blue.
Thanks for the photo i check the wiring tomorrow. I love this race. Every week is a new price.
Kncminer is gonna shit their pants when Avalon/Bitmain hits $3/GHs
Yeh talk about it... Both of them are printing out chip like no tomorrow. Their production costs are under $3/Ghs with these small time shops doing mines with almost no labour cost. The amout of TH/s Avalon & Bitmine are shipping out atm. Could hit Kncminers and others hard.. This blade might not be power efficient but Chinese are good at being cost effective in production... and they always have rival factory cloning same things with -10% They might make these ALOT. Is this 105-110GH/s with ~350w power not good but ships out in high volume.  Now. I wonder whats factory price for that blade atm. Maybe ~200$ for this blade... could be as low as 100$ soon. I predict DIY hasher 200Gh/s for 500$ After CNY Holidays Chinese Avalon clone is ~1200$ 200GH/s |

3. LOUD sound.
Is there a option available to reduce the fan speed to automatic mode?
--avalon-fan in CGMiner settings under more options. I believe the setting is in reverse though, put it at 90 and it is quiet, 20 and it is full speed. edit: by quiet I of course mean quieter, these are nothing like the original ones for sale at the start of this thread (with video evidence in the thread showing them being quiet). The fans are 36w and even at the lowest setting are too loud to be in the same room with, it's like server equipment. I have two units one is reverse otherone is not. Unit1 with working RPM in webui "--avalon-fan 20" seems to put the fans around 20% very quiet Unit2 with unworking RPM in webui "--avalon-fan 80" seems to put the fans around 20% very quiet. Value 20 is very loud 80% |

For those of you who ordered this with power supplies and received one of the new versions of this miner does the new version of the miner work on 120V circuits like the original version? Since mine have finally shipped I need to figure out if I should order power supplies.
Photos of the PSU it says 170vac - 240vac dont have 110 in Europe so i cannot blow up one of these to test Light is bit poor but expand enough and you can see the 170vac http://imgur.com/a/x3o86https://i.imgur.com/0RT7VIw.jpg |

Could someone post the dimension of the fuse, or what SMD package they used? Also do they have any number printed on them to help identify what they are? I ordered a few of these miners so I might as well order some spare fuses.
Thanks for digging into that problem. Hopefully the ones I get will be OK but better to be prepared.
Here's all I have on the fuses I pulled: Surface mount, two square solder pads on the underside of each fuse. Length 3.4 mm Width 1.66 mm Height 1.25 mm Markings "8 0" That's all there was. Is that enough for you to tell us the appropriate replacements? If so, what is the next higher current? I'm presuming DigiKey would be fine? Thanks! - Tye Thanks for the info. That would probably be a 1206 (3216) sized fuse then. I tried looking at some manufactures to figure out what the rating would be. I have not found any matches though. The 80 probably represents the rating however the various manufacturers do different codes, there is no standard. And it does not mean 80 Amps. I asked BTmine for the rating, hopefully they will let us know. I'm willing to pay bounty to oneone helping me to fix why these 5 units are not hashing, left ones are. Chips inside the red area are all cold. I cant see anything wrong in the board but i'm no SMT expert. I can solder tho.      I can take better pics of the components tomorrow. half speed  |

Other then the delay time. The crap build. @ 2050 it was not a bad price. Now getting that money back and then some that's another story. They said my stuff will get to me today. I just hope it's not in to bad a shape. I am guessing that they did not test the units before they got out.
Did anyone get the stock PCU working on 110? And is the built in wifi good enough to run?
No offense, but you can get an S1 (180GH/s) for 1.9BTC right now. Considering the majority of these were delayed and wont ship for some time still...still think this is a good deal? Yeah considering that to do that I would need to get a refund. Convert $ to BTC then send coin to BITmain then wait for shipping. Unless the units you speak of can reach 220 GH/s the. U are correct. At the time when i made my BTmine orders and paid.. Bitmine was out-of stock and not shipping also price was 2.4 BTC or more. Back then this was a good deal. i dont take account the electricity costs here, i only wanted neat packet with as many GH/s i can get. All the delays and such cost maybe 1 BTC loss of mining with easyer difficultys... only if you would have ordered these in December... they would have done ROI by now. It's the game of Bitcoin mining and buying hardwares the market is so so Overheated atm. that thers no good deals out there. Only maybe Bitmain now. Only company that ships, they have so big production going on right now they sold +6k units in Taobao for Chinese customers -30% (7500¥)what they charged from overseas clients past month.. They can afford several price drops still in next months. Antiminer might go for 1 BTC soon. Their production costs are much much lower. Best deal is what you can get in-hands and hashing right away. +1 week shipping is something you can expect anything you order from Shenzen mainland China. |

You can control fan noise with --avalon-fan in CGMiner extra settings.
Thx i tested randomly some values to that is "--avalon-fan 50" running them in 50% ? Seems so the unit went quet. Unit1 with working RPM "--avalon-fan 20" seems to put the fans around 20% very quiet Unit2 with unworking RPM "--avalon-fan 80" seems to put the fans around 20% very quiet. Value 20 is very loud 80% if i swap values they both go 80% haha they got some cables crossing? |

https://www.dropbox.com/s/5d6stcwhspe2uv4/2014-01-20%2012.32.55.mp4https://www.dropbox.com/s/r02ak0tpnxdidhj/2014-01-20%2012.50.16.mp4Download for HD quality Here is 2 of these babys hashing away. Dropbox fails and rotated the video 90d download to view propelly. Sound is not that bad from the unit which has working fans that report RPM ~2500 it's not loud at all. Left unit in the video has fan RPM report 0 in the webpage and it's fans are stuck at 100%. All cables connected but i'll propably replace the fans later. luv my babys they are hashing nicely and i got more coming tomorrow. Sofar so good. i let them warm up then replacing psu etc. more photos coming. http://imgur.com/a/x3o86First one of my units had ugly dent on it. I suspect someone has dopped it at factory. Stock PSUs are two Rail 12v 25A Both of my units are hashing 180GH/s ..... out of the box. Further inspection shows their QA  too bad they are in a hurry and tired. This is what i find.        After fixing those broken pins my miner is doing 220GH/s now. Reported hash in BTCGuild 221GH/s      So be ready to QA your miners. I'm opening the second one now. -Edit- Disassembling and reassembling the scond unit brought life to those 2 missing modules didnt find anything wrong but after careful reassembly it's hashing 220 too now. Quess the backplane was loose in that unit. ps. DHL picked up more units for me

Just got my 2.4 BTC refund.
At least they eventually kept their word. Shame I could not get what I wanted.
Anyone know of any reliable deals going on ?
Honestly at the moment they were the best deal. All of china is going to start selling these machines in a couple of weeks. +1 next months market is flooded with these Avalon chip machines and difficulty will get another 10 days +30% 10days + 30% bumbs. This was the best deal after Bitmain Antminer S1. I like that i can get more GH/s out of this ignoring the electricity. Every seller has stock issues because this stuff sells, all they can produce. Antminer maybe gets more stock every week but i cant see any deal that would reliably ship next week before CNY holidays. During holidays whole China will shut down and 1billion people will move places to go home see the family. it's biggest human movement in the world. So for next 3 weeks it's hard to get any Chinamade ASIC from order to in-hands. I also like this unit because it's in neat case. I've tried to order more of these but they didnt take my orders. I got several units in DHL hands now. Monday will be setup day Special thanks to twib2 and FarmerOak for studying the board. I have bypassed some 2amps fuses in my 13port USB hubs that run Antminer U1 sticks. Seems so i will be doing same stuff for these boards when they arrive. My initial plan was to hook them up with dual 1200w psus with 100A single rail. Maybe 1 PSU could handle the stock speed but it's never good to run psu at 100% capacity 24/7. That being said maybe these stock psus cant handle eaven stock speed for longer timers, we will see. PSU i'm gonna try. http://www.fspgroupusa.com/aurum-pro-gold-1200-au1200pro/p/881.htmlhttp://www.hardocp.com/article/2012/04/18/fsp_aurum_pro_gold_1200_power_supply_review/4#.UtupX7Q8LRY |
