The only thing that might be an issue is the noise from a fan due to the location of the setup, if I can get the same level of cooling from a heat sink I think I'd rather do it silently.
I'm using a normal 80mm computer case fan (12V@0,02A) with a 7.5V AC adapter and I guarantee you that it is quite noiseless. I'm just waiting for a power adapter for my hub and I'll put all my BE's next to the Ants in the same hub, and then, put them on a "shoe box" to properly manage the heat and create some tunneling to improve airflow and have it neatly arranged. But let me ask you: besides the noise, have you already tried to use 0981 frequency and a fan? even for one hour. That way you'd check if it is some heat issue or not. And you might have some USB Hub lying around that you could use instead the extension cable? These are just some ideas to troubleshoot your problem. |

Don't worry about the 5 second rate, it's the long term rate that matters most.
It is safe to experiment with the speeds so long as you have some cooling. Try from the lowest speed first, then build up and see what happens.
Give each setting plenty of time to stabilize before trying the next one. If you go above 2Gh you will probably need a powered hub to supply the extra current.
OK thanks, I've just restarted it at 0581. I'll run that for 24 hours to see if it brings the HW rate down, if it does I'll leave it at that until I've got a decent heat sink for it. I'm looking to salvage an old CPU heat sink or similar from somewhere and just get hold of some of those CPU pads as the go between 1 hour is probably enough, then up the clock and try the next one, then keep upping till the error rate shoots up.(then go back one step). Up to 2gh air cooling with a small fan is usually enough. Above 2Gh then the power resistors need to be modified to reduce the error rate. I second that: Get a fan and cool the Ant miner down. Look in here: https://bitcointalk.org/index.php?topic=7216.0 for plenty of examples using BE's and other miners. Also look earlier in this topic. You don't need any special heatsink under the 2.2gh/s. |

I've been running my antminer for about 24-hours using the following instruction: cgminer.exe --bmsc-options 115200:20 -o stratum+tcp://mint.bitminter.com:3333 -u user_worker -p 123 --bmsc-freq 0681 Does this look healthy to you? I should add, it's not plugged into a hub or anything, it's straight into the USB port on the front of the PC. I'm considering running it at 0781 once I've got a heat sink and CPU pad to put on it, any thoughts on this appreciated, thanks  You have a quite extreme hardware error rate...!! I'm running mine with 0981 and in less than 12h I get this: cgminer version 3.9.0 - Started: [2014-01-13 21:42:48] |

What could happen if I don't scrub the connection? I've done the +5v mod to all ports and the hub will work for a couple of hours but then it'll drop out and the block erupters stop mining. The only way to fix it is by unplugging the hub from the PCs USB port and plugging it in again. Could this be caused by not scrubbing the connection? [/quote] you need to scrub it or cut the red wire on your usb cable. [/quote] Sorry to ask, but, what if I scrub and solder the right diode in there? What kind of diode (rating, voltage, etc) do you think it should be ok? BTW, I don't have that that Capacitor near the power plug... What's his ratting? Thank you! |

Desta vez fiz ao contrário.

Nada a apontar.

why do all the reading come as a multiple of 512? (512,1024,1536,2048,2560)
Because the difficulty on the pool is set to 512. If he were mining with any other number, it would be a multiple of it (10, for example): --------------------------------------------------------------------------------

Sorry to ask, but what is this fix? As I've understood, it is trickier to have BE's and Ant's correctly identified. Would one instance of old cgminer (BE support enabled) on one terminal specifying the USB ports of the BE's and another instance of the forked cgminer (ANT support) on another terminal specifying the USB ports of the ANTs allow them to run at the same time? Thank you and great job! The fix from https://bitcointalk.org/index.php?topic=390929.msg4250179#msg4250179 to prevent it from crashing on 64 bit ubuntu and possibly other distributions. And yes, I suspect that running one instance of the ANT specific version of cgminer manually specifying the usb ports as well as a second instance of cgminer to run BE's would work Great news!! Thank you, once again!!! |

0.09? Puxadote!! Tendo em conta que existe as Nanofury de 2.2/2.5 GH/S a 0.15BTC não me parece que seja um bom negócio.
Mas pelo que percebi, estas são precisamente a 2.2-2.5 também!! (Não são BE, são Antminer, apesar da imagem ser muiiiito semelhante.) Não são 2.2/2.5, o vídeo que o sushi disponibilizou mostra bem o hashrate! 1.6/1.7 É claro que poderás fazer OC mas não é a mesma coisa. eheh Continua tudo com preços altos  Nem no Natal!! Hum, só vi o print, nem reparei se há alguma indicação de O/C. Mas sim, se nesse caso é caro... 'suspiro'!!! |
