Hi,
I recently purchased a cheap non working Avalon Mini 60GH/s, after opening it up and having a good fiddle, I found that a single miner (1 of 8 miners per module) on one of the modules (1 of 2) was fried and causing the PSU to trip out and shut down the miner.
I simply removed the 20 pin socket from that miner so it is no longer connected to the backpane and it now powers up fine and mines on 15 of the 16 miners at around 55 - 57GH/s on high clock (375MHz).
I'm not that familiar with Avalons and I am not sure if I have more problems with the miner and can't seem to find any documentation about it. I noticed that I always have a much larger number of discarded shares compared to accepted shares.
For example, this is a screen shot of the share details after a couple of minutes running to show you what I mean:
https://dl.dropboxusercontent.com/u/67953101/Screen%20Shot%202014-04-05%20at%2007.18.56%20pm.png
As you can see, accepted = 73 but discarded = 282. Does discarded mean bad shares or does it mean shares that were lower than the min difficulty I had set (64 in this case). After a few hours mining I had around 3000 accepted shares, but there was over 5000 discarded shares.
Is this something wrong, or just the normal workings of the miner?
Reply from someone that knows would be appreciated.

Re: Need Help, Block Erupter Cube, Solo, Stratum_proxy connect to Wallet QT
You are running Bfg with the correct settings, is the Qt client fully synchronised with the blockchain relating to the coin you are solo mining?
You are correct about the performance loss using Bfg, I see similar, but I have still successfully mined thousands of lower difficulty SHA256 coins that way. Maybe you should ask Slush if it's possible.

You're asking something that nobody can answer for you.
Maybe there was a dip in the power supply and then a slight surge, it happens from time to time and may have been enough to trip the protector.
It's all working again now so just see what happens.

BE tube or do you mean BE Cube?
I've tried to get the stratum proxy running for solo mining via the Qt wallet and gave up very quickly. Much simpler way is to install Bfgminer and proxy through that using the --http-port option, works a dream. Don't forget to run the Bitcoin-Qt with the -server argument.
Although it has to be said if you are only planning on solo mining with a BE Cube, you're wasting you're time, you will never solve a block.

Hi, thanks for your help.
I already have a good idea of what I am doing, I have a couple of BE cubes and a couple of Antminer U1 rigs. Trying these thumbs to see what they're like.
Followed your helpful guide and built the provided cgminer version on my Pi no problem, however when I run the newly compiled cgminer it does detect the thumbs and shows them as active, but they do not hash and instead I periodically get timeouts from them:
[2014-03-16 22:29:31] DRB 1: Timing out unresponsive ASIC 0
I built the same version of cgminer from the git repo above on my Mac and it detects the thumbs, but not correctly, I get the same message as I was having before:
Drillbit detect (20:7) failed to initialise (incorrect device?)
Think I will just stick to the U1's and cubes for now until hopefully Bfgminer will be updated for proper support for these new thumbs.
I appreciate the input though, thanks.

1.) What are you running the stratum proxy on? If the machine hosting the proxy is slow and underpowered it can restrict the speed, especially with two cubes running via 2 proxies. Your log output looks normal and working correctly.
2.) Have you tried just running one cube to see if you get full speed with just one?
3.) What is your internet connection like?
4.) The PSU's you are using should be fine, they are capable of supplying 38A on the 12V rail which should be enough for high clock , just, but a better PSU would be advisable for high clock. If you are trying to power two cubes off one of those then it's underpowered.
5.) Make sure no Android devices are connected to your network while mining, this can affect the speed.

I bought a couple of these new Drillbit Avalon Thumbs to try out.
http://www.ebay.co.uk/itm/321343641493
Arrived today but I can't for the life of me get them working on either my Mac or on my Raspberry Pi rig.
I have tried the latest Bfgminer and Cgminer (with drillbit enabled during configure) but neither will recognise them.
My config file is as follows:
With the devices plugged in I can see them in /dev/ as /dev/tty.usbmodem* & /dev/cu.usbmodem* but no matter what options I run Bf or Cg with it won't find them, neither can I add them with the programs open. I have tried with "drillbit:all", "drillbit:/dev/tty.usb*" and "drill bit:cu.usb*" all with the same result.
My understanding was these should have worked the same as the previous Drillbit Thumbs?
Anybody else got these and made them work?

Re: We have an Asic Cube Miner and want to know if we done the correct steps?
Seems OK, although it shouldn't be that complicated, they are pretty easy things to get going. Was it a new or used Cube?
What fan was with the Cube when you bought it? The fan can affect the miner if it is faulty, but if it's rated correctly & working fine it should be OK. The fan in my cube is upgraded to a Scythe Gentle Typhoon, that is a 1850rpm fan, but it is much quieter and moves more air than the rubbish stock fan. I tried a Corsair Air Series SP120 High Performance Edition (2350 rpm) fan in my cube, but then it would not power on, the relay just kept clicking and resetting the cube over and over in a loop. The Typhoon draws a current of 0.083A, while I note the Corsair draws 0.18A, so maybe if the fan is drawing too much current or not enough is the problem with the fan, maybe check yours?
Also, when you say the fan needs to be blowing out of the cube, do you mean you reversed your fan so that it is essentially sucking air across the blades and through the cube, or is it blowing into the cube across the blades? As you look at the rear of the Cube with the LED's, fuse, power ports etc, the fan should be blowing inwards, although I guess it won't make much difference as in theory it should be moving the same volume of air over the heat sinks.
What PSU are you using, the power supply can be a cause of a lot of problems with Cubes too.
Everything else seems sine, although I would advise against keeping bit coins in an online wallet. Much better to send them to one on your computer such as the official Bitcoin-Qt, which you can then back up regularly to another location or paper etc.

Other things to check are:
Heatsink bolts tight?
Also don't use the highest clock, in my experience with many U1's it just gives you a shed load of errors. I get a steady 2.0 GH/s off all my U1's using 0981 and goes days with literally no errors.
Was the USB hub you tried powered or passive? Get a powered hub and you'll be fine.

Is this best practice to create a local stratum? Cant the Miner connect directly to the pool?
If your chosen pool still allows you to use the old network protocol then you can mine directly. If the pool only has stratum protocol servers then you either need to use Cgminer or Bfgminer as a proxy or set up a dedicated stratum mining proxy.

Is there any way i can setup and run my 32GH/s block erupter cube on my macbook pro? All my research is telling me it can't be done. Just wanted some last opinions before i have to go out and get hold of something cheap running windows.
Thanks for any advise you can share.
Thanks for any advise you can share.
It's simple to use via your Mac. Don't listen to the rather ridiculous (sorry) idea of running Windows emulators and don't entertain buying a new system with Windows on it! lol
Download and build from source the latest Bfgminer. There are plenty of help threads for setting up Bfgminer config file. To allow the cube to mine without a stratum mining proxy, simply run Bfgminer to your chosen pool, with the --http-port option enabled. Then point your Cube to the local IP of your Mac using the port you specified. Hey presto your miner will now mine on your pool via Bfgminer on your Mac.
If you wan't a lower power consuming set up, I would advise perhaps buying a Raspberry Pi and either setting up the stratum mining proxy such as Slush's, then connect via the Pi instead of your Mac which would draw more power (and lets face it, would you rather leave your expensive Mac on 24/7 or a inexpensive RPi?) Or you can run Bfgminer on the Pi and mine that way like above. Just point the miner to the Pi instead ion that case.

Re: Need help setting up ASICMiner Block Erupter Cube 30GH/s to 38GH/s Miner
Can anyone assist me in the setup of 2 Asic 30GH/s-389GH/s cubes via skype or telephone. I am willing to pay. I have them out of the boxes and PSU connected and running I can see them on the net 192.168.1.254:8000 but I don't understand how to configure them to mine in my pool. I REALLY need some help and I am willing to pay for so0me help.
I'm sorry, but have you actually searched for and/or read the detailed setup guide on this forum. It couldn't be any simpler than to just follow the steps. You certainly don't need to Skype or call and give away your hard earned Bitcoins

Can only echo the above, don't bother with the x0A91 clock setting, none of my U1's like it either, hashing errors go through the roof and rejects too. But also that pool looks crappy. Are you even using a powered USB hub, or is is passive? With 4 U1's you need a hub with at least 2A available, preferably more.
Try x0981 or even x0881 clock settings, using a lower clock but getting more reliable and stable hashing is better in the long run when you have errors like that.

Re: Getting inconsistent speeds with my Ant Miner U1 USB ASIC (OSX)
Got an update for you.I've managed to update Asteroid and the hashrate is much more stable,in fact it's fixed my issue more or less (meaning that I can sell contracts again without worrying about misrepresentation issues caused by unstable hashrates).Would would have thought that a software update was all that was needed? Now I don't have to waste time with any other approaches.
It doesn't reach beyond 2GH/s anymore but I'm sure they can still be overclocked (but first get a fan) for a better hashrate.
Thanks for the suggestions though.

Glad to hear the update fixed it for you, as I said I tried it and it was very buggy, would never close down properly etc after mining and sometimes wouldn't let me start at all. They must have fixed it.
Have you felt how hot it gets running at 2.0? I would still use a fan, with a simple USB fan they stay barely warm to touch, without they are too hot to touch almost. For longevity a fan is a good idea. Look on eBay for Arctic Breeze USB fan, very cheap but very useful.
Re: Getting inconsistent speeds with my Ant Miner U1 USB ASIC (OSX)
Firstly, Asteroid is rubbish and really buggy I find, what your seeing with the fluctuations is normal for Asteroid as far as my experiences are concerned. I tested it on my Mac with my rig of Antminer U1's and it did the same. The latest version of Asteroid has the proper support for Antminers so it utilises the higher clock speeds automatically, but as you have found it goes up and down a lot. You should ditch Asteroid and install Bfgminer on your Mac for much more reliable hashing. There are plenty of set up guides for Bfgminer and the U1's.
My Antminers are all controlled via a Raspberry Pi now which stays on 24/7 and uses a LOT less electricity than leaving your Macbook on all the time. You should consider something similar as you're probably paying more on electric than your getting selling 2GH/s mining contracts. But on my Mac while testing Bfgminer with my U1's using the x0981 clock setting I get a reliable and constant 2.0 GH/s. When you first start Bfgminer and it starts mining, it's normal for the GHS to spike to very high, as much as 8 or 9 GH/s in some cases, or it may start really low with a few hundred MHS, this is normal and it levels off after a few minutes.
Secondly, you say you are selling mining contracts, with a single 2GH/s Antminer?! Are people actually silly enough to pay for 2GH/s mining?!

I would use a better alternative except that they're all terminal based and as a busy pro filmmaker I really can't afford to waste any time whatsoever.
I'll update Asteroid too as it's worth doing to see if it improves.Running my MBP with an Ant Miner uses very little energy (less than 15w combined) compared to using my mining PC with the asic which would burn though over 130W for the same task,without a GPU.
The mac also let's me use a scrypt based miner as I figured out how to make it work whereas no Raspberry Pi OS supports both BTC/Scrypt ASICs yet.
I would use a raspberry pi except that I don't know how to set one up and read my first point for the rest of it.Too time consuming as none of the guides mention how to flash the OS onto its sd card on a mac.
As for revenue,let's just say I'm doing quite well in revenue and electric costs when selling a mining contract,I've had a few customers already so it can't be that bad can it?I want to use the extra money in funding an important film project as well as invest in upgrading mining equipment to sell more mining contracts.
If you or someone can create an easy to understand guide for flashing the OS and setting up the Raspberry Pi for asic mining,that'll be great. I find most guides on here too much of a pain without images to explain and actually show me what to do along with good instructions which is what puts me off the Raspberry Pi route/after hearing reports that MinePeon may have a security vulnerability that causes a users hash power to be redirected somewhere else without the user knowing.
I'll hold off a Raspberry Pi until the dust settles in this.
I followed the tutorial by Adafruit and adjusted it to my requirements. It's a very easy to follow tutorial which you can alsmot just copy and paste the commands if you like. I did it all on my Mac, they have instructions for Win or OSX
