Check the screws on the heat sinks are tight.

One of my 10 was slow as shit (7-900MH), on careful examination the heat sink was about 0.1mm off the board.  The screws weren't tight.  Tightened up and it's running around 1.8GH no problems now.

All 10 are hashing fine in an Anker 10-port hub plugged in to a Celeron NUC.  Running the terrible cgminer on Windows 7.  What a faff getting them working, I have to start cgminer then plug each stick in individually, waiting until the previous stick starts hashing.  cgminer also seems to refill the queue slowly - the sticks stop hashing for a few seconds, then are given new work.  I don't know if cgminer just sucks, or the antminer fork is broken. 

I paid for the ASICMiners using BTC I mined using GPUs.  GPUs that were sold for more than I bought them for (bought cheap off eBay and sold for more than I bought them 6 months later when more folks wanted those GPUs for mining).  So, only fiat spent was the GPUs, which I got back.  Power was paid for by fait received after selling BTC.

I have never spent fiat on mining hardware.  It's always been BTC produced mining. 


So, yeah, just because you suck at mining doesn't mean everyone does. 

There's something with these Cubes and the CX750.  Lots of folks have them working perfectly with this PSU, and others like me can't get the Cube to work for shit with the CX750.  It's frustrating.

My Cube ran perfectly at High for a week on the OCZ 600W PSU, but it locks up on High.  Works OK on Low, though.  I need to rewire a bit to get the Cube running off both 12V rails on the OCZ.

Can't say I'm very pleased with the Cube - it's a fussy fecker.  Not like the old Blades which have been rock solid.

Can't say I'm seeing the same.  cgminer is taking about 20% CPU on the Celeron 847 NUC I'm using - once bfgminer is updated and I don't have to use that WinUSB balls, they'll be going over to the BeagleBone Black. 

I haven't tried overclocking the sticks yet - it took me long enough getting cgminer to play ball, so I'm afraid to touch them while they're going. 

They should be on.  One is the link light, the other flashes off on activity.

Arrived OK here too.  Mining away, though it was a major ballache with zdiag and cgminer.  Terrible software compared to bfg.

The Pi's USB support is broken at best.  Don't bank on getting them working on the Pi, ever.

They run perfectly on a BeagleBone Black, which hasn't got broken USB.

They're cheap, and 10 of them gives you 20GH with negligible power consumption. 

Yeah, it's through a DLink 7-port.

Feature request:

Any chance of the MinePeon front page being able to display stats from another instance of bfg/cg?  MinePeon's front page obviously uses the API, but it'd be brilliant if it could show stats of other cg/bfg instances on the network?

Currently I'm using the normal miner.php hosted off my NAS to display stats from my 2-3 miner instances, but it's ugly and clunky.

BFG's proxy for me is a little slower than slush's proxy on the Cube, though BFG's proxy is faster for the Blades, I suspect it's due to the lack of Longpoll on BFG's proxy.  But I just use BFG's proxy as it's easier to manage, and I don't have to run a PC for the whole thing.

With the Antminers arriving today hopefully I think I'll be mining on the PC again for a little while - at least until BFG with ANT support is released, then it'll be back to the BBB running Debian in expectation of MinePeon for BBB.

Any chance of a Windows binary with ANT support?  Screenshot is very nice and all, but I'm loathed to run cg (with all the zdiag and WinUSB bollocks fecking up the USB drivers) to get these things working.

crhys, It'll be the PSU. 

I had the same problem, the Cube basically killed the PSU I was using (an old Dell PSU with 18A per rail).  Everything ran fine initially, but the Cube started to fail in the same manner you're describing, until it stopped working totally. 

Changed the PSU and everything started working again perfectly.  Now running off a PSU with dual 25A rails.

I've a Cube @ 38GH and two V1 Blades at 13GH each going through BFG's proxy on MinePeon.  Current uptime of 4 days and still trucking along at 60-64GH.

There's something wrong with your network or your Pi.


(My Pi is powered off the back of my Airport Extreme, Blades and Cubes are connecting via Powerline adapters, so my rig is not optimal in ANY shape, form or fashion).  

No, it's shit.  It's the SOC's USB that sucks, so unless they change the SOC the shit USB is going to be there for good.  If they change the SOC, then it's no longer a Pi.

That's why the BBB works, it uses a totally different Ti ARMv7 SOC, not the older ARMv6 in the Pi.


To be fair on the designers of the Pi, the USB was there for a USB keyboard and perhaps a USB wifi dongle so school kids could get the things running (hence the composite video output also).  It was never designed to run 20-odd bitcoin miners hanging off multiple hubs.  They would probably have put a couple of PS2 ports on the thing if they had designed it a few years earlier...

The BeagleBone Black's design is more geared towards the 'hobbyist', so faster more capable SOC, better cape support, and the eMMC is fantastic to have.

"Out for Delivery" 

I'm currently sitting in the front room, watching the road like a hawk to see the green van arrive.  The bugger's not going to have any excuses for not delivering today!

nwoolls has drivers working for "The other miner that can't be mentioned", and will be merging them to it's git soon.  Perhaps ck and kano can do something with his code?

Well, no, that's false, but hey don't let facts get in the way of a good argument.    I've never bought BTC for fiat, every BTC I've mined has been reinvested or cashed out to fiat.


Agreed on the first point.  

However, my running costs are essentially zero when averaged out across a year, and over the year I've been mining I've spent essentially nothing in fiat to keep my BTC production around 1BTC every 6 weeks.  1BTC every 6 weeks means I can keep up with increase in difficulty by buying new hardware, and sometimes my older hardware is sold to top up that BTC fund - I sold my 10 Block Erupters and bought two BlueFurys.  Selling the Blues paid for the 10 Antminer U1s.  Without spending a fiat penny I've gone from 3.3GH to 5GH to around 20GH.

You also have to consider that I'm not really in this for profit.  I have a good job that pays me enough that I live comfortably and have enough left over at the end of the month to not only save, but spend on my hobby of building PCs and buying little things to tinker with.  Mining is a hobby.  Some people play games on XBox.  Some people go and piss £100 up the wall on a Friday night.  I mess about with my miners.

Just use the supported, stable and useful software that is bfgminer.

I'm looking forward to it - I would nearly buy another BBB, but they're terribly difficult to find in stock anywhere in the UK or EU.  The Pi is dead on as a little network device, but it really does fill it's pants when asked to do a lot of USB stuff, especially considering the NIC also hangs off the USB bus.   Looks like I'll be running a pair of MinePeons - the RPi for proxy service, and the BBB for the USB miners, as I am now with Minepeon on the Pi and Debian on the BBB.  Heck, the BBB even works with the Anker 10-port USB3 hub!

Only real complaint about the BBB is the lights - they're OMG bright!
