Excellent work! Thanks. How much is room temperature? There is any extraction fan?

Recently I have noted there is a new model from Bitfily. The B3. www.bitfily.com/product/snow-panther-b3/ Chip energy efficiency says only 0.081J/Gh, so, not a big improvement from B1+ but price (~669.00USD) and stock availability are interesting.

Quote from: hatem31 on August 09, 2019, 08:45:11 PM hello I just delivered your asic b1 +, I try to turn it on but there is a problem that I can not solve: 1- the blue lights on the three sets of hash board PCI-e connectors is not keep on. 2 - the configuration page does not show any status it remains blocked. https://imgur.com/a/0T4AV9U Have you resolved this issue? Blue leds should turn on in a few seconds. If not, try to disconnect from mainboard one of the fans, and reconnect after blue leds turn on. There is a new english website: bitfily.vip, but you cannot make any orders. And their original chinese website is still online: bitfily.com We have received a new batch of B1+. But It´s different in some details, like mainboard. Here is a short video and screencap of efficiency and performance mode. https://imgur.com/a/3Kw58uN I will add some details later.

I'm sorry to hear that, Zimba. It is a very weird situation. Their chinese website it is still online. The company I work at, recently (about 7 weeks ago) have completed a huge buy of 500 or more B1+ asic units. The last new I have hearded was the shipment was sent on time and will arrive in only some days (maritime transport). I will keep you informed about that.

Quote from: Artemis3 on April 04, 2019, 01:01:15 PM Actually I'm more worried [...] Thanks for your very interesting opinion. These containers are inside a warehouse. So, IMHO, the insulation you are talking about is perfect if the high temperature are caused by direct sunlight. But, in this case, the ambient air itself is at high temperature. The most important insulation we have is intake air from output air. Humidity is not definitely something to not worry about. I think the biggest problem in this type of containers are the close distance between the pads and machines. The farther the better. We are running this type of containers more than a year ago. Not much problem have caused any than rust in fan grill. Other farms nearby have adopted similar cooling systems since mid 2017. Their biggest mistake was miscalculation of air flux (sorry for this dull vocabulary and not explain with technical terms). I have not heard yet some big problem caused by humidity in these farms. In raining conditions or extreme humidity, of couse, we switch off the water pump.

Quote from: coffeefan on March 29, 2019, 01:50:52 PM Is that a solution where you make the filters / cellulose pads wet to provide cooling? For how long have you run them? Max temp.? Send a PM, interested in your solution. Is just water at ambient temperature. The first containers was made a year ago. It provided a cheap and efficient solution. For best results next step will be use cold water. But we not have tested that option yet. Outside temp is 32c https://imgur.com/P0wkYjE and behind the pads is 28c https://imgur.com/r7OfrrW

We have containers specially designed for hotter enviroments. I am working in a mining farm in Paraguay and weather here is very hoy in summer. Winter barely goes to under 5C. So we have to deal with the hot weather almost all the year. With our very cheap solution we can down 5 to 8C below ambient temperature. Here are some pics. https://i.imgur.com/HVzonD0.jpg https://i.imgur.com/rw0VSlf.jpg https://i.imgur.com/MuPvrCu.jpg

Hey, thank you for the merit @ZimbaCardi I am not a electronic specialist like many here, but I think is not very good idea to connect conventional Psu to B1. User NotFuzzyWarm already talked about that Quote from: NotFuzzyWarm on October 15, 2018, 07:35:03 PM DO pay close attention to the power specs for this! The miner CANNOT use a normal PSU. It requires 2 different voltage inputs, one for the control board and a higher voltage one for the hash boards. From their site: 3. If the voltage for the miner’s control board doesn’t range from 10.8V to 13.2V and the voltage for the hash boards doesn’t range from 14.5V to 15.5V, the miner may fail to work or even breaks. If you look at their PSU for the miner it is dual voltage out... It seems it is very difficult to find a replacement for B1's Psu. Rabinovich also talked about other Asic that uses 14-15v PSU. Innosilicon T2. Maybe this Psu can work with B1? http://www.innosilicon.com/html/2200w-psu/index.html But, it´s 14v not 15v. I will keep searching.

I am glad to know that, ZimbaCardi. I have positive feedback too about post-sale service of Bitfily, but same as you, I had to pay customs taxes. They have send me a PSU that is capable of handle hotter conditions. Is OK now. One thing that has helped me is use 2 PSU per Asic. I mean, one psu for 2 hashboards. It works very well.

@ZimbaCardi, PM'd you. At least, I tried It's just about temperature conditions, my B1+'s psu cannot handle 32C and above, it makes the miner crash. Have you experienced something similar?

on: November 28, 2018, 10:34:37 PM

hey ZimbaCardi, do you speak spanish? I can't send you a pm. I am facing some serious problem regarding the psu.
