Bitcoin / Mining support / Re: Block Erupters 32gh/s clicks and shut down

on: January 26, 2014, 01:08:18 AM

Assuming everything is bolted in after transit it will be a power issue. I had it do this one two different 750W atx supply's but it booted fine on a (noisy as hell) bench supply. Using a 600W corsair CX600 it works fine and has power to run some hexminers. I think it is to do with the initial spike in power and that some PSU's don't handle it well.

None of them even detects the bifury's Is there anything in /var/log/messages that shows up when you plug them in ? Does your raspberry board work with other USB devices, like a memory stick ? Can you use usbmon (https://www.kernel.org/doc/Documentation/usb/usbmon.txt) to make a USB trace when you plug in a bifury device ? I dont know if there is anything in that path, didnt know i should look. The rasp works fine with other usb devices, such as mouses, keyboards, and 5 different usb memory sticks, in size from 256mb to 8gb Gonna check up on the usbmon tomorrow. Those are all low power devices though. These things use way more power than most USB devices. Remember the Pi was built as a cheap device for educational purposes and is not a fully fledged computer. If power concern is an issue why not look at buying an old lenovo think pad off of ebay and using that as a host? you can pick them up for not much more then a pi and a USB 3 port going to USB 2 ports on the thinkpad would work.

Quote from: rallasnackbar on January 22, 2014, 02:42:14 PM Still cant get my bifury's to run on raspberry... If its the same problem a week from now, im going to sell them again. What a waste of money and time, and no support from sellers what so ever. DONT BUY THESE* They won't run on a rasberry pi as the native usb ports do not give enougth power. The pi also does not detect USB 3 hubs which you pretty much need for these. Try hooking the pi up to a POWERED USB 2 hub and make sure it has plenty of power. Using a 48W USB3 hub i can only run 4 of these on one hub.

I had a DOA that when it arrive reported a temperature of 20C and did nothing, usually you plug these in and they report 50C before they start hashing. Sent it back and the replacement came and reports temperature as 100C before it begins hashing. This has not been a problem as i have used the temp cut off option in cgminer to stop it throttling as they are all under cooling and never reach more then 55C. However now it is showing no more then 1.7GHs with cg miner started with cgminer.exe --drillbit-options ext:230:1:950 --temp-cutoff 110 on 3.10.0. Running on a USB3 hub and nothing has changed. I am guessing i have had a chip go bad but thought i would post in case CGminer preemptively cuts off before the 110 limit, i have tried the different firmwares but get the same result. Anyone know what these use as a temperature sensor? and if there is a way to trick it back to normal range(i suspect my DOA was returned with a tricked temp sensor)? Upgrade to the latest firmware. cgminer also supports a target temperature for these: --bxf-temp-target <arg> Set target temperature for BXF devices (default: 82) It does not cut off, it throttles to the slowest possible speed if it's over the range. Yep was on the latest firmware but buggered up my batch file using --temp-cutoff instead of --bxf-temp-target. Classical case of PEBKAC thanks for pointing me in the right direction

Quote from: FalconFly on January 19, 2014, 11:50:05 AM Just my 2 cents : - miners have RoHS, FCC and CE Logos -> AFAIK no mining product ever went through all (any?) of these certification processes, as they are expensive and consume way too much time in this fast-moving industry ( we all know time-to-market is literally everything ) ASICMINERS cubes and sticks have these logo's as well but i highly doubt they went through approval so this means nothing. Merely stops it from getting rejected at customs, IIRC BFL did similar as things were being stopped for wrong power cords etc.

I use 2 power supplies and have problems with the 5v (I think) leaking from the Hex16Bs and competing over a shared USB. It would cause the miners on 1 power supply to fail soon after starting mining. Either put them on seperate TP-links and hubs or what seems to be working for me right now (runs 2.5days before crashing) is I cut the 5v cables on the molex and power the TP-Link from the power socket not the USB hub. Thanks i ordered a separate TP-Link but in the meantime some fiddling around with boot orders and it seems to be stable now. Also replaced stock fan with arctic F9's and what a difference. Heatsink runs about the same temperature as the 16A2's where before it was cold but it was like having a jet turbine in the room!

I am so close but there is still something going wrong. Anyone know why this happens? Are the boards powered 12v? Doubble check it pls I have a corsair rm750 connected to the boards. I am retrying everything again tonight i'll seewhat happens otherwise i'll set up TW. Other thing a common mistake that I have with some customers. If your boards are with wire terminal did you happened to connect the red wire to + and black to - GND? If so change it to Yellow + and Black - GND. If this is not the case , please excuse me I was not intending to offend you. Best Martin Hi Martin, Thanks for the support! I have the molex connector so that shouldnt be a problem. I will be plugging in the boards one by one tonight to see what happens. The ATX supply is running correct right (PSU fan spinning etc)? The devices themselves will be picked up by cgminer and have there fans spin purely on USB connection. I found them like this once when my psu decided to take a nap.

on: January 07, 2014, 04:08:56 PM

What hub are you using? These things eat power and are best used in USB3 hubs that the pi does not like. Minepeon also only has bfgminer 3.4 and cgminer 3.6 on the standard image which probably does not support these. You will need to update minepeon through a git pull rather than downloading the image again.

Quote from: FalconFly on January 01, 2014, 09:09:10 PM No, it's a powered USB 2 Hub (10port, only 4 occupied). The config ran for weeks without issues. Strangely, after moving around the BiFury into another Port several times and reverting to cgminer 3.8.5, everything is back to normal. I do notice though, plugging it out and back in temporarily seems to interrupt power to the other ports, causing 3 BlueFury miners to go offline for a short time. Could be my powered port is operating near its limits (5V/4A should be plenty for 4x 2.5W devices I thought). I may take a PowerMeter and get a good estimation of total consumption of that powered USB hub @ full load. Its power, Use a USB 3 hub for these even if it is going to a usb 2 socket on the motherboard

Quote from: FalconFly on December 31, 2013, 11:07:15 AM Hm, since 2 days I'm running into a curious issue : cgminer 3.9.0 shows my BiFury at 0 MHashes and room temperature (the hub with the USB devices is cooled well with a large USB fan, the other 3 BlueFury installed in the powered 10hub USB port run completely normal). Restarting cgminer either via options or restarting the program works, the BiFury runs absolutely normal (0 HW errors reported) at rated speed - until it after some hours or a day silently drops to 0 MHs again. The only thing I changed in the setup was basically going from cgminer 3.8.5 to 3.9.0.... (I left the Firmware untouched since purchase as it ran flawless so far) Is there anything known in cgminer 3.9.0 to cause this maybe? Right now I've taken the BiFury onto its own USB port with extender chord and placed it into the airstream (the usual 40.8deg Celsius @ full load) , seeing if that helps. -- edit -- Didn't help, BiFury went to 0MHs after about 1 hour. I reverted back to cgminer 3.8.5, hope that fixes the issue. Was it a USB 3.0 port? These things are power thirsty i can only run 4 on a 48W USB 3 hub before i get issues similar to what you describe. Anymore then 4 and there is an issue but 4 + 1 Drillbit/Nanofury + fan works fine

Quote from: Zich on December 31, 2013, 03:07:16 AM After searching for 2 day, i found FAN that at least half of SUNON PF92251v1-000U-S99 performance & available in local computer store. My first choice is Zalman ZM-F2 Plus but not available at the moment. So i buy Zalman ZM-F2 LED which is more expensive because of the useless LED. So, now HEX16A2 move to bedroom joining 2 x HEX16A on TPLINK TL-MR3020 Are these 5v or 12v as the page did not have the information? Also is the noise difference that noticeable? One last question what are you using for PSU as i have one powered by a bench supply (loud) and another on an old ATX PSU (Quiet). Waiting on some adapters so i can use ATX supply for both, it has a 36amp 12 v rail so should handle both fine and i'm planning to use the another 12v connection as the molex wires are a little warm already.

You can just cut off any molex connector, strip yellow and black to connect, and tape the red and other black to make sure they don't touch anything. Thanks. I bought molex connectors just in case to strip. My Mid november for december order arrived 23rd dec and had screw terminals. Think they are moving molex to special request

Look forward to getting my grubby mitts on them Edit: Marto Some of the Nano's are for resale, as manufacturer i take it these is no issue if end users return to you for replacement should the need arise?

Quote from: FalconFly on December 11, 2013, 05:10:46 PM Credit where credit is due : - received mine today just 4 days after ordering (Poland - Germany) = darn awesome ! - worked right off the start after installing it as "USB Device" with Zadig Utility WinUSB driver - runs 5GH/s as advertised @ 41 deg Celsius using cgminer 3.8.4, cooled by USB powered fan Overall, a nifty and compact device, works just as advertised. Posted this because I'm simply impressed by the delivery time, that's a big thumbs up! I have had a similar experience when these first appeared but had to RMA one due to DOA. They were quick to respond and resend once the unit got back to them, even included a free usb fan. They ship them out very quick and have not had any issues since The new unit is showing as over 100 centigrade when it first plugs in unlike the older ones that showed 50 centigrade when first plugged in. This is a cosmetic issue as it is hashing fine (bang on 5ghz actually ) but is this something to do with the new firmware? all of them are running under cooling with the first batch showing 48 centigrade and the new one 104 centigrade. I have seen people saying they are getting 90 plus centigrade on there devices post firmware upgrade but is this an actual temperature figure as the one i have showing 104 is definitely not at that temperature. All are plugged into USB 3 hubs running cgminer 3.8.3 with an artic air fan above them (old ones on one hub, new one on other hub).

There are 5 BEs and 5 BF1s, each od them on its own USB hub ( 3,5A powered). It was try with connection of hubs into cascade ( BF1s hub connected to BEs hub and this to computer) and also try to connect hubs directly to computer and always the same result. If i reset BF1s with reset switch on board it comes back. Today i "upgraded" to version 3.8.3 and i still get this LIBUSB error: Code: [2013-11-23 12:12:24] Hotplug: bitfury added BF1 8 [2013-11-23 12:12:38] BF1 8 BF1RequestWork usb write err:(-7) LIBUSB_ERROR_TIMEOUT [2013-11-23 12:12:38] BF1 8: Device disappeared, disabling thread [2013-11-23 12:12:38] BF1 8 failure, disabling! Does anyone else have this issue ? If the device disappears and shows up as ZOMBIE and never re-hotplugs, there's nothing there on the USB any more for cgminer to talk to, so something is causing USB flakiness there. Check what 'dmesg' shows you after this has happened. There's not much the software can do if the device is effectively disappearing from the USB hub. If on the other hand the device is still there and it's just cgminer dropping out, it's possible that cgminer is too trigger happy - but if that were the case it would re-hotplug soon after. Hi ckolivas I get this problem on a windows x64 machine. Devices are a mixture blue/red fury and will randomly Zombie. I have tried everyhting to rule out flaky USB (Zadig, diffrent hub, unplugging anything usb except keyboard/mouse etc) and i am currently running 4 on there own Orico hub. They will zombie out and not come back but still show as being present in device manager/ devices. If i power cycle the hub (it has a nice switch at the front) they come back as normal. Hope this info helps and thanks for your hard work!
