What's the highest temperature Avalon chips can bear?
The original fans work at over 2500rpm and the sounds just like jet plane. I plan to replace with lower rpm but don't know the safe temp.
2500 RPM is nothing... Try anything above 3840 RPM.... Play with the --avalan-temp settings, I have it at 45, default seems to be around 50 degrees Celsius The RPM's adjust to keep the temperature < 50 degrees in the default setup, so try to output your warm air into another room and get colder air from somewhere. Don't mix the warm outlet air into your inlet It's difficult for me to keep the temp below 50 at this season. That's why I ask the high limit of the temp. |

So anyone had problems with the tp-link WR703N wifi router on theses things? This is a Rev1.1 board. I can't connect to any computer to interface with it. (Of course by setting a static ip address on the comp eg. 192.168.0.101 and accessing the router via 192.168.0.100) And my network switch doesn't detect it. Bad router, or can I reflash? Is there a way to access this board via serial?
It might mean the ethernet interface on the router is flaky or dead. Try a crossover cable directly to the unit. Also try a different computer. If the same on multiple systems then yeah there could be something wrong with it. There is a way to access via serial but it would involve soldering your own serial cable to the board. There is a howto on the openwrt wiki or somewhere. If all else fails you could temporarily hook up the unit to your PC/mini pc, etc. Just remember to remove the J1 jumper before you plug in the USB cord to any device as it backfeed power (how the system powers the router). By the way I found a guy here on the forum that is selling modified (in the same fashion as the avalon unit's tp-link router) tp-link routers. Thats the other thing, I can't find a good tutorial on how to mine on this thing via usb. Driving me crazy. Its windows xp im using and I've setup zadig but cgminer can't see the miner. have you changed the jumper? I think it is J1, but they're talking about P5 on the wiki About P5 jumper: close this jumper will supply 5V to the USB-B port. in this system, the controller board power the 703N from the client side. if you connect the controller itself to a PC, you better remove the jumper. Yes done awhile back. |

The jumper is labelled J1, it will be just next to the USB connection on the controller. |

While I was doing an OpenWrt Failsafe which worked fine, I noticed i had to jam my ethernet cord unusually hard into the tp-link router. Upon inspection of the router one of the ethernet pins was bent out of shape. Go figure some tester bent the crap out of it. Works fine now. thx everyone for the help |

Hi, I am having some problems with my Avalon since it arrived yesterday. I don't really mind if it restarts a few (like 2-5) times a day. If it automatically gets back up working in a minute, it is fine for me. What is crucial for me is to prevent it manually switching off and on. It happened this (its first) night that it somehow crashed and in the morning I thought it was operating well (fans worked normally) but I was not able to connect to it at all. Had to manually switch it off and on to have it on the network and hashing again. I am using firmware 20130703 from CKolivas (runs much better than the original, which restarted every 10-15 minutes), flashed with Keep settings enabled, default settings mostly (except for my new attempts to solve the problems - see below), default clock 300. I would like to ask you some questions: 1) The default "ideal" operating temperature is set to 50 C. How sensitive is Avalon to this? Might it help if I lower it down to 45 C? I might be able to cool it down even to 40 C, so I would like to know if there is any benefit of doing so. Any clues? 2) It is quite simple to "analyze" what is happening there if it just stops hashing and restart cgminer. That can be seen in the logs and I do have these ugly guys when it restarts: ...

... But my question is now - how to analyze what happened after I had to switch it off and on - i.e. logs gone. Or is this just try/fail all the time? Those error -71 are quite known here. Some of you get rid of them just using the new firmware. Somehow this did not work for me. I now tried to use avalon-temp 45 + disable DHCP server and we'll see. But since the problem with total network disconnect happened after several hours of working, I'm not sure how to test it properly. I do not know if this -71 has something to do with that total crash, I just know it is related to cgminer restarts. I would really hate to have to open the case. I do not really trust myself with this  Switching jumpers, playing with cables, screwing something somewhere up and get brick ... So unless it is necessary I would like to operate on the level of web interface and ssh. Thanks for any help, clues, links. |

Some had other experiences, but the exact same problem went away for me when I switched to wireless and (software) deleted the lan. Be careful with deleting the lan, don't do it until you're certain that you can reach the avalon over wireless.

By "deleting LAN" you mean disabling it using Stop button in Network -> Interfaces ?
And one more question: If the temperature changes I can hear fans going down and up again, would it not be a good idea just to put all fans on 100 % in order to get the lowest temperature possible and at the same time not putting stress on fans by changing their operational conditions?

Yes, first disable and when wireless is ok delete it. You can always activate it again via ssh. I don't see any harm in setting the fans at 100% all the time, except for the noise. Maybe others see it differently? |

My 2 sets of Avalon have different performance. Same environment, 1 set is totally perfect, rarely restart. 1 set is restart for every 1 or 2 hours. I have met 2 times it cannot restart by itself. I have to monitor the performance via pool site to ensure it's working.

... TEXT REMOVED ...
Thanks for any help, clues, links.
are u finding these in the System Log or the cgminer API log? That was the system log. But it should be noted that since I have add made two configuration changes: - --avalon-temp 45
- disable DHCP server on LAN interface
it works perfectly. It had 6 hours of work without event restarting cgminer and then I had to turn it off in order to transfer it to another location and there it now has 14h 50m 31s cgminer uptime, which is great. So this is 21 hours without even restarts since those two changes. There are no -71 bad guys in the log since then. However, I would consider it fixed when I have something like 5+ days uptime ... |

******* Avalon ASIC stopped working: /dev/ttyUSB1 missing ******* 1.0 BTC REWARD TO THE FIRST PERSON (or Persons) WHO CAN GIVE ME THE CORRECT ANSWER. (If multiple person leading to correct solution or answer, I will split the 1.0BTC among those who helped.) I have two Avalon ASICs. Both were working fine for about two days, but one of them is now missing /dev/ttyUSB1. I tried updating the firmware, and I'm now using 20130607, but it hasn't solved the problem. I tried using mknod to create /dev/ttyUSB1, but it didn't make cgminer work. I opened up the avalon to check and make sure the USB cable to the TP-LINK is connected, and everything looks fine. PLEASE EMAIL ME DIRECTLY: Please POST AND EMAIL me directly with your answer to thejamesfund@aol.com with your solution. If it works, I will send you 1.0BTC for your time. Thank you. Also include a BITCOIN ADDRESS in your reply/post for reward payout confirmation. |

try firmware 0703 from CKolivas, that helped me a lot
also, if even after updating firmware there is still the very same problems it implies it is a HW problem
what are all the symptoms? does LAN work? does WIFI work? everything works except the hashing itself - i.e. cgminer?

Hey guys, I've tried to sell my batch 2 avavlon but I couldnt find a buyer. So I decided to start a raffle for it. For 1 BTC per ticket you can win my avalon with express delivery. (the raffle cant be manipulated through we use the blockchain to find the winner) https://bitcointalk.org/index.php?topic=254816.0 |
Einer trage des andern Last, so werdet ihr das Gesetz Christi erfüllen.

Please consider reasonable price 250 BTC is insane and do not spam tech treads also. Thank you |
