Windows cgminer support:

As mentioned above we have full support in the master cgminer branch. If you are a Windows user and you already know how to download and get cgminer running on Windows, then you are good to go. Just get the latest version. These miners are identified as "BXM" devices by cgminer.

cgminer binaries: http://ck.kolivas.org/apps/cgminer/ (http://ck.kolivas.org/apps/cgminer/)
cgminer source: https://github.com/ckolivas/cgminer (https://github.com/ckolivas/cgminer)

If you want a statically built (no extraneous DLLs) Windows cgminer with *only* the Bitfury USB drivers enabled, then download this build:

https://www.dropbox.com/s/pdlfk4z3tisokfm/cgminer.exe.zip (https://www.dropbox.com/s/pdlfk4z3tisokfm/cgminer.exe.zip)

Note: you must first follow the Zadig instructions to set the Windows driver to WinUSB. The instructions are summarized here:

1. Download Zadig: http://zadig.akeo.ie/

2. Insert one BFx2 miner into a USB port on your Windows machine. If you have never installed any FTDI drivers, then Windows will fail to install a driver. This is OK.

3. Run Zadig. Use the drop-down to find the "Single RS232-HS" entry. If it doesn't show, select "Options->List All Devices"

4. Set the new driver to be WinUSB and click Install (or Re-Install) driver.

5. Exit Zadig and install any other BFx2 miners you have.

You can now run cgminer with your favorite command line options and/or config file.

Linux cgminer support:

Since support for this miner is in the master cgminer branch, getting a Linux binary is as easy as downloading the latest cgminer-<version>-x86_64-built.tar.bz2 file from:

http://ck.kolivas.org/apps/cgminer/ (http://ck.kolivas.org/apps/cgminer/)

Please read and follow the instructions in the ASIC-README file provided by cgminer. It will help you get your Linux set up to use USB based miners.

If anyone needs a 32-bit Linux binary that will work on a recent Ubuntu (tested on 13.10), reply to this message and I'll post one.


Title: Re: [SUPPORT THREAD] BFx2 Bitfury USB stick miner

Example cgminer command line:

./cgminer -o stratum+tcp://<Pool URL> -u <Pool user> -p <Pool pass> --bxm-bits=XX

Where XX is in the range of 50-55. I recommend some experimentation to find the best setting for your particular miners.

Since people will ask what hashrates these get, I've been running mine at bxm bits 54, but they are engineering samples and not final units. Nonetheless this is what I have:

Code:

Hiya mate,
you might want to add the Amperage ratings to the USB hubs on your website, I know that the dipo one is 20A which makes it a "monster" for USB mining. Each port delivers 5.26VA which should easily support 19 on second thoughts only 18 (the spacing of the 3 ports on the side may only allow 2) of these miners simultaneously. Still should be able to get 72 Gh/s (minimum) off 1 hub.

cheers,
kev

Post by: goodney on March 27, 2014, 06:09:39 AM
There has been a request to discuss over clocking these boards. I'm the designer of the board, and these are my thoughts on over clocking, but of course your results will vary and you could end up destroying your boards! I don't recommend doing any over clocking, but since Bitcoin is about experimentation, here goes nothing!

These boards were designed to run at 4GH/s with ambient cooling on the heat sink. This allows them to run at <500mA and thus be USB2 compatible. When over clocking a Bitfury based design, heat is your enemy, you will need active cooling from a fan if you over clock these boards.

With the way Bitfury chips are designed, heat really is the enemy. As the chips heat up, they slow down and also start producing hardware errors. Software over clocking will increase the heat dissipated by the chip and thus can actually produce worse results. Same with increasing the core voltage.

Software over clocking:
The current cgminer release supports software over clocking with the --bxm-bits=XX command line parameter. Non-over clocked optimal is 53 or 54. However, you can go to 55 or 56 if you introduce active cooling.

Increasing the core voltage:
In order to get the Bitfury chips to run stably at higher clock values increasing the core voltage is necessary. Again, the boards were designed to get to 4GH/s so the core voltage was chosen accordingly. Increasing the core voltage will really increase the heat output. Cooling the boards with a fan is absolutely necessary.

The core voltage is set by three resistors, but the only one you want to change is R6. It is right in the middle of this picture:
https://i.imgur.com/3sviOIOl.jpg (http://imgur.com/3sviOIO)

As built R6 = 499 ohm, to increase the core voltage use a larger value, but don't go above about 1.5k. You'll need a 0805 surface mount resistor. To measure the core voltage the chips are seeing, measure across the decoupling capacitors that surround the Bitfury chips. Explaining how to desolder/solder a resistor is way beyond the scope of the forum ;-)

Active cooling
I thought it might be fun to add a 40mm fan to the heatsink:
https://i.imgur.com/lFZRwDol.jpg (http://imgur.com/lFZRwDo)
https://i.imgur.com/iAXwBVTl.jpg (http://imgur.com/iAXwBVT)

To do so, find a 40mm fan and screw it to the heat sink. Then solder the wires to the USB connector as indicated above.

Anyways, have fun hacking up my creation!

Linux cgminer support:

Since support for this miner is in the master cgminer branch, getting a Linux binary is as easy as downloading the latest cgminer-<version>-x86_64-built.tar.bz2 file from:

http://ck.kolivas.org/apps/cgminer/ (http://ck.kolivas.org/apps/cgminer/)

After unpacking the archive file you will probably need to do two things:

#1: Blacklist the ftdi_sio driver: copy the following single line to /etc/modprobe.d/blacklist-ftdi.conf

blacklist ftdi_sio

#2: Fix the permissions on the devices so you can mine without being root: copy the following single line to /etc/udev/rules.d/01-ftdi.rules

SUBSYSTEM=="usb", ATTR{idVendor}=="0403", ATTR{idProduct}=="6014", MODE="0666"

or you can follow the instructions in the ASIC-README file provided by cgminer, which will do both of the above.

After doing #1 and #2, reboot and you should be good to go!

If anyone needs a 32-bit Linux binary that will work on a recent Ubuntu (tested on 13.10), reply to this message and I'll post one.
I think your instructions are overly complex and I highly recommend people just use the cgminer way. There is but one step to setting up on permissions on ubuntu (as per  the README):

Code:
sudo cp 01-cgminer.rules /etc/udev/rules.d/

Pencil Trick Over clocking

I kept hearing about a "pencil trick" to over clock other miners and after looking into how that works, it will work on these miners too.

The resistor you need to color is R8. Coloring just a *little* bit of pencil across the resistor will increase the core voltage a few 10's of mV, which is needed to over clock the miners.

Again, if you do this I would recommend a fan!

Virtually every single bitcoin pool of any signficance only use stratum+tcp, and most miners using cgminer use stratum to mine, so that's a definite yes.

They are very stable at 4GH/s, but to get to 4GH/s they'll draw 5W with --clock-bits=54. With a fan you'll have no stability problems.

Unless that damage is in the form of scratching up the port because of https://i.imgur.com/8cEBpMB.png , that laptop would have to be returned under warranty and not accepted back.  Proper USB ports don't care about 'too much' current draw.. either they'll sag in voltage in response to the point where the overcurrent situation dies off, or they just plain shut down (either through a passive 'fuse' or through active management).
above does not apply to any miners that accept external power - that has to be isolated properly from the host device

Yes, you need a powered USB hub. If you want to run a lot of them, klintay has a 49 port hub sale (which will support 28 of these units physically). His thread is here: https://bitcointalk.org/index.php?topic=528371 (https://bitcointalk.org/index.php?topic=528371)

From the silkscreen, 3 of them appear to just be power indicators (one for the 3.3V regulator, one for the 1.8V regulator, and a separate one for the core voltage(?)), and the 4th one the usual status LED.

So install a winusb driver for it. Follow the cgminer instructions, not whatever windows thinks it's doing.

BFx2 support merged into BFGMiner git (Windows builds can be obtained here (http://luke.dashjr.org/tmp/code/webisect/webisect.php?dobuild=bfgminer)).
Note that since it's impossible to tell it apart from various other devices (including BFL/Cairnsmore1 miners and even many non-mining devices!), you must run with the -S bfx:all option.
I do not know what this will do with other devices; it may start fires, launch nuclear missiles (please don't run BFGMiner on computers with missile controls), etc. (this warning is true of cgminer in general btw; BFGMiner is no less safe than that)

Thats strange  ??? ??? ??? any ideas Goodney?

Is your usb wifi adapter running on the same hub? Is there a power surge or something?  Try plugging the wifi adapter into a different port.

Also it may be because your USB wifi adapter is being automatically turned off by windows for an unknown reason.

Solution:

Go to Device Manager (Control Panel\System\Hardware\Device Manager), and find the hub the wifi adapter is plugged into. On the last tab called "Power Management", disable the tick that says "Allow the computer to turn this device off to save power". This should be the thing that fixes it. If not, whilst in Device Manager, go to Network Adapters, and select Properties on the wifi adapter, and turn off its power saving options there as well...

What is the name of your usb wifi adapter?

Could also try the new compiled version of bfgminer and see if you still get the same problem.

When I run these on my windows machine, I get disconnected from my internet after a few minutes of hashing. I have tried this many times now. It is something with these devices? as my dualminers and ants and BEs always ran for days and days without any issues like this. Any tips to fix this?

(I am using a usb adapter to connect to my wifi network at home)

Thats strange  ??? ??? ??? any ideas Goodney?

That is indeed strange, I too am running my mining machine with 25 of these with a Wi-Fi adapter for the network. However, I am running linux.

My suggestion is to make sure the Wi-Fi adapter is on a different port, or if possible different root hub on the PC. This should separate the mining traffic from your Wi-Fi connection. How many miners are you running?

Could also try the new compiled version of bfgminer and see if you still get the same problem.

Yes, please try this. Thanks to Luke Jr. for his very quick work.

If you are getting dropped from wifi in Linux and you're using a Raspberry Pi it is because of wireless power-saving mode. Put the line "wireless-power off" in your /etc/network/interfaces file to fix this, then either restart wireless or reboot.

BFx2 support merged into BFGMiner git (Windows builds can be obtained here (http://luke.dashjr.org/tmp/code/webisect/webisect.php?dobuild=bfgminer)).
Note that since it's impossible to tell it apart from various other devices (including BFL/Cairnsmore1 miners and even many non-mining devices!), you must run with the -S bfx:all option.
I do not know what this will do with other devices; it may start fires, launch nuclear missiles (please don't run BFGMiner on computers with missile controls), etc. (this warning is true of cgminer in general btw; BFGMiner is no less safe than that)
So, using this?
Code:
bfgminer.exe -o stratum+tcp://us1.ghash.io:3333 -u <USERNAME> -p <PWD> -S bfx:all --bxm-bits=54

With cgminer, I still have the same issue of my computer getting disconnecting from the wireless network.

But I am curious what are the four LEDs for?
From the silkscreen, 3 of them appear to just be power indicators (one for the 3.3V regulator, one for the 1.8V regulator, and a separate one for the core voltage(?)), and the 4th one the usual status LED.
Yup.

Ah. Thanks for clearing that up. I was blind.  ::)

And if the red led for the core voltage is not lit, it indicates that the device is not getting enough power from usb?

Hrm... it could indicate several fault conditions. The LED is lit when the VCORE regulator thinks the VCORE voltage is being regulated within tolerances. So:

Is the miner still working? How many GH/s?

Did the VCORE LED ever light? Or is this a new fault?

Can you try it on a powered USB hub or USB3 hub?

Does it light when you plug it in and then go out when mining starts? Or does it never light?

What is your clock bits set to?

Did you do the "pencil mod"?

Do have a multimeter? Do you know how to use it?  ;)

Thank you for your detailed answer.

I think it was because my Anker 3.0 10 Port Hub can only handle six twin furies.
Whenever I plug in a seventh device the core voltage led wont lit while the other six are.

Example cgminer command line:

./cgminer -o stratum+tcp://<Pool URL> -u <Pool user> -p <Pool pass> --bxm-bits=XX

Where XX is in the range of 50-55. I recommend some experimentation to find the best setting for your particular miners.

So, higher this XX number, higher the hashrate? Do we do the pencil when we go higher than a specific number?
@54 I am getting avg of 4.28/stick.

Regardless of the pencil mod, the optimal bits setting is going to be between 53-55 (maybe 56). The way the BitFury works is that the speed is a combination of bits and core voltage. The pencil mod will raise the core voltage and thus increase the hashing speed.

Also, if you increase the core voltage enough you might actually get better results with a lower bits value. The trade-offs will show up in the error rates.

If you do the pencil mod, please, please use a fan on the miners as the will *require* more cooling.

I find it helps if you provide some extra cooling via fans and that keeps them hashing at full speed.

Hi, need help

I'm trying to run 3 TwinFuries with 6 RedFuries with bfgminer 3.99.0 provided by luke-jr here.
I'm using Orico A3H10 USB hub, the remaining 1 slot I use a USB fan to cool the miners.

My problem is I can only get 3 TF and 5 RF working, one of them doesnt work.

I try running 3.10.0 bfgminer and I can get all 6 RFs working.

I try to run separate instances but if i use for example - d 0 , it only enables 1 chip and disables the rest of the miners.

Is there a command line I can use to make them all work ?
Thinking of running  two separate instances the 3.10.0 bfgminer for the RF and the 3.99.0 for the TF, please help ?

6 RedFuries ~ 15W
3 TwinFuries ~ 15W

Total is about 30W. The hub comes with a 48W supply. Throw in conversion efficiency and the power for the hub itself and you *could* be bumping up against the power limit of the hub.

So the simple test is to try with one RedFury and one TwinFury. If that works, then keep adding miners until it doesn't work.

For bfgminer I would go get the latest version and try the following:

bfgminer -o stratum+tcp://<POOL URL> -u <USERNAME> -p <PWD> -S bfx:all --set bfx:osc6_bits=54

This should enable all TwinFury miners and the RedFury's should just work too.

If you try separate bfgminer instances, then you should do:

-S bfx:all -S bpm:none for the TwinFury instance

and

-S bpm:all -S bfx:none for the RedFury instance.

I tried your suggestions and  i can make two instances running tf and rf exclusively.

However i run the 6 rf first and then the 3 tf.
At first all rf runs fine after i run the tf
Bfgminer for rf immediately drops 1 of the miners in this case bpm 4.
And for bfgminer running 3 tf throws user privelege error
Help again please ?

If i unplug one of the RF so running 5 Rf (12,5W) and 3 Tf (15W) then bfgminer also like when running 6 rf drops the speed of 1 of the miner.

We need to determine if it is a Windows, hub or software issue. It seems like either Windows or the hub, and adding the 9th device is the problem.

Do you have another hub, or other USB ports on your computer? Since the RedFury miners are USB 2 power compatible, I suggest plugging the RedFury's into another hub or into ports directly on your computer. If this works, then it is a hub issue.

If it still doesn't work, then it is likely a Windows issue. Can you confirm that the two combination of 8 miners works (6 RF, 2 TF; 5 RF, 3 TF), but adding the 9th miner causes problems?

Will I be able to use the BFx2 and an Antminer U2 on the same machine using CGMiner?

The reason why I ask is that my CGMiner options are device specific:  --icarus-timing=short --anu-freq=300

So I don't see how I can control a BFx2 at the same time. Or can I run multiple instances of CGMiner?

You can run more than one type of ASIC device on one CGMiner instance. The options are ASIC specific and only affect that type of ASIC. So just add --bxm-bits=XX (where XX is 52, 53 or 54) to your command line and you're good to go.

Post by: Buchi-88 on May 11, 2014, 08:33:54 AM
There has been a request to discuss over clocking these boards. I'm the designer of the board, and these are my thoughts on over clocking, but of course your results will vary and you could end up destroying your boards! I don't recommend doing any over clocking, but since Bitcoin is about experimentation, here goes nothing!

These boards were designed to run at 4GH/s with ambient cooling on the heat sink. This allows them to run at <500mA and thus be USB2 compatible. When over clocking a Bitfury based design, heat is your enemy, you will need active cooling from a fan if you over clock these boards.

With the way Bitfury chips are designed, heat really is the enemy. As the chips heat up, they slow down and also start producing hardware errors. Software over clocking will increase the heat dissipated by the chip and thus can actually produce worse results. Same with increasing the core voltage.

Software over clocking:
The current cgminer release supports software over clocking with the --bxm-bits=XX command line parameter. Non-over clocked optimal is 53 or 54. However, you can go to 55 or 56 if you introduce active cooling.

Increasing the core voltage:
In order to get the Bitfury chips to run stably at higher clock values increasing the core voltage is necessary. Again, the boards were designed to get to 4GH/s so the core voltage was chosen accordingly. Increasing the core voltage will really increase the heat output. Cooling the boards with a fan is absolutely necessary.

The core voltage is set by three resistors, but the only one you want to change is R6. It is right in the middle of this picture:
https://i.imgur.com/3sviOIOl.jpg (http://imgur.com/3sviOIO)

As built R6 = 499 ohm, to increase the core voltage use a larger value, but don't go above about 1.5k. You'll need a 0805 surface mount resistor. To measure the core voltage the chips are seeing, measure across the decoupling capacitors that surround the Bitfury chips. Explaining how to desolder/solder a resistor is way beyond the scope of the forum ;-)

Active cooling
I thought it might be fun to add a 40mm fan to the heatsink:
https://i.imgur.com/lFZRwDol.jpg (http://imgur.com/lFZRwDo)
https://i.imgur.com/iAXwBVTl.jpg (http://imgur.com/iAXwBVT)

To do so, find a 40mm fan and screw it to the heat sink. Then solder the wires to the USB connector as indicated above.

Anyways, have fun hacking up my creation!

Miner runs really well without the "bxm bits = XX" entry? If so, how fast, or the entry is absolutely necessary?

I don't think I'm seeing the performance from my 3 Twin Bitfuries that I'm supposed to be getting. I'm running with 2 Antminer U2's as well. The Antminers are overclocked. The BXMs are unmodified, I'm running the BXMs with (cgminer) --bxm-bits=52.

I'm also getting a lot of work restarts and stale shares that I never got before with just the 2 U2's. The problems get worse if I run any higher, and seem to increase over time.

It this typical or is there something I should do differently?

I performed the mods shown here... I added a fan and replaced R6 with a 1.2k resistor. I have 3 of them in a cheap powered USB hub. Here are my observations:

1. First of all, the fan makes a huge improvement in heat. Before it was not possible to really touch, now you can handle it easily. Of course they now physically take up 2 USB ports.
2. Running CGMiner, I played with the bits settings and bits=54 yielded the best result.
3. Running a single unit in the hub, I see a fairly solid 4.8-5Gh with spikes higher, but it degrades to 4-4.3 over time.
4. Running more units lowers the speeds into the 3-4.2's. I assume it's due to not enough power from the hub.

I'm not sure if I'm doing something wrong, but I'm disappointed I don't see the solid 5G performance with these mods. Maybe I should do the pencil mod also?

You might see better results with BFGMiner, so try that and report back.

Adding the fan is a huge help. Since you seem to be handy with soldering, do you have a DMM? How many volts are you getting across the decoupling capacitors near the BF chips when hashing?

I agree for bfgminer seems better hashrate ,it has reconnect issues though you have to restart if you got disconnected.

I have a few issues and follow-up information.

1. OK, I am new to BFGMiner but I downloaded the version from the link in the thread (windows 64). There is an error on startup that I don't think is relevant, I don't know what I am doing wrong, but it still seems to run OK:
ub_path():506: The parameter is incorrect.

startup line is:
bfgminer.exe -o http://stratum.btcguild.com:3333 -u (user) -p (pass) -S bfx:all --set bfx:osc6_bits=55

2. I measured voltage across the capacitors surrounding the BF chip. Is 0.82V reasonable?

3.
Here are the results after running 7+ hours with bits=54:

Try downloading the newest git build from the link that Luke-Jr just posted.

2. I measured voltage across the capacitors surrounding the BF chip. Is 0.82V reasonable?
That's pretty good, but to get to 5GH/s it will probably need to go a *little* bit higher. Since you added a fan you have some more headroom. Try the pencil mod, or better yet since you changed R6, you can try a larger value for R6 (or smaller for R8, but it's better to leave R8 alone and increase R6). I'd aim for 0.85v for the next step.

OK, I updated my BFGMiner and installed the 1.5k resistor, as well as a better USB hub. One unit always seems to be a little low. I'm nto sure if it might be a manufacturing variance for the unit or using multiple units in one hub.

I measured pretty consistently between 0.835 and 0.845V on those capacitors.

Running at bits=56 doesn't work. Running at bits=55 seems to be optimal.

Any comments on all of the frequency drops? This is after 1h45m.

That's normal for the BF chips. This is BFGMiner babysitting them for you.

Good day,

I have a problem with one BFx2 Miner, one miner always lose the "red light" at one USB Port "14" and run very slow, is this a problem fro the USB port or to less power from the port?

The miner runs but without the "Vcore" light!???

Yes, that means the VCORE went out of regulation as far as the switching regulator is concerned, but it is still possible for the device to work.

Does the same device fail in the same way if you use a different USB port?

If you run BFGMiner you can also look at the device to see if both chips are working properly. Please try BFGMiner and then use the device options interface to see if both chips are reporting good hashes.

If they all fail on that port, then the port is probably bad.

Try BFGMiner to see if you get better/more stable results.

If you start cgminer with the extra option "--api-listen" then you can query cgminer while it's running to see how it's performing. While cgminer is running you can do:

Code:
java API stats

and in there you'll get lots of info, one will be the BXM device and in there will be the separate core submit data:

Code:
   [Core0 submits] => 250
   [Core1 submits] => 270

If one core is failing, the submits will be a lot less or even zero compared to the other.

Code:
java API stats

and in there you'll get lots of info, one will be the BXM device and in there will be the separate core submit data:

Code:
   [Core0 submits] => 250
   [Core1 submits] => 270

If one core is failing, the submits will be a lot less or even zero compared to the other.


Good day, thnks i will test it on evening ;)

The BFx2 also needs an extra fan to provide cooling. In my experience the speed will drop if you do not provide a fan. After providing cooling you can also use the pencil mod to increase voltage and then speed up the miner.

I think --bxm-bits=54 is the best as well.

Hello,

no only on this "one" port, and only when my Raspberry also hang on this HUB!?

I use Cgminer 4.3.3

You need to use Zadig on BFx2 to get the WinUSB driver.

This is nothing to do with your web browser, don't know where you got that idea. This is just typing 'java API stats' on the command prompt from within the cgminer folder while cgminer is running.

You need to use Zadig on BFx2 to get the WinUSB driver.


Did that and now it doesn't see any devices at all. Ran it with "bfgminer.exe -o stratum+tcp://mint.bitminter.com:3333 -u <user> -p <pwd> -S bfx:all --bxm-bits=54" and it tells me that "--bxm-bits=54" is an invalid option.

That's because --bxm-bits=54 is an invalid option.

Are you using 4.0?

Post by: janonathon on June 01, 2014, 09:40:25 PM
Nope, was on 3.10(thought that was the latest, so does google), now it sees the BFX, mining at 4.2GH/s! which is fine for me, calls my ICA's BES though for whatever reason.

I'm not overclocking it with that command line am I? because I've only got it on passive cooling but in a pretty good flow of the A/C.

Thanks for the help.

NM, that's hot anyways, puttin a fan on it.

Wow, a real world Icarus is still mining? :D
Block Erupter Sapphires are more common, so BFGMiner 4 assumes them by default.
You can tell it that it's an Icarus with -S icarus:all

Well, what i bought were sapphires, seems every other program calls them what they want to. The ones that do 333MH/s.  I say it's better than an empty usb port, when i've got the amps to spare anyway.

Hello,

I'm using two antminer U2 (working well), and I have just added a bitfury twin.

Bfgminer 3.99 or 3.10 doesn't work if both models are connected (I'm compiling 4.00 version). Alone, bitfury works.

With cgminer 3.4.3, all worked, U2 at normal speed, but the bitfury is under 100MH/s.... alone, she is 4GH/s easily.

Is someone have ideas to try ?

The usb hub is powered enought (3A, for just the U2 and bitfury connected).

The BFx2 also needs an extra fan to provide cooling. In my experience the speed will drop if you do not provide a fan. After providing cooling you can also use the pencil mod to increase voltage and then speed up the miner.

Video link on how to pencil mod:
http://youtu.be/jm0U3p_C9og

I think --bxm-bits=54 is the best as well.


So the Miner automatically adjusts down if it gets too hot? And also back up when it cools?

At time i use "53" but 2 miners are slower then the other.

I've got a worst problem:
2 of my 3 BFx2 are aside until I solve my problems with my hubs.
The one I'm plugging them, somehow doesen't deliver it's 3,5A to the ports.
When I plug one other, the further from the usb cable doesn't light the vcore led.
If I unplug the one with vcore's led lit, the other one light's the led and start's mining.
On other hub I get "unrecognized device", although Antminers, BE's and pen drives work on it. (although somehow i can't have more than 4 antminers for now, even with 10A... something weird over here...)

Do you have new Stickminers in planning?

None of the current chips seem to be worth producing a StickMiner. They all use too much power for a useful hash rate. The closest I got was this BE200 based prototype @8GH/s. But it got way too hot, even with a huge heat sink.

If anyone knows of a chip coming soon that might be good for a stick miner, let me know!

OK THX for your answer ;)

BITMAIN doesn't sell your chips BM1382 only?

As far as I know the BM1382 isn't available to 3rd party developers. It would also have to be underclocked/undervoltage to work on a stick. Probably 12 GH/s.

If BM1382's are available for 3rd party development, I'd be interested to know that.

Even if they are, the real problem is the rest of the BOM cost...

Only good on power consumption(if proved  :D)

They showed data in the OP photos ~0.5V@1.85A but unknown ghash rate. Also he stated that it will me marginally more efficient in a "string" mode where the power chain starts at say 12V into "first" chip and ground for first chip is fed into Vcore of second, repeat until a chips GND output is ~0V

This how the bitfury strings worked and I'm assuming that they'll work similarly here(based off of pinout)

Get me samples and I'll knock out a StickMiner. Assuming the protocol is similar to the BE200 it wouldn't even take that long ;-)

Question is whether it would actually work as one - your BE200-based one was nipped in the bud by the fact that the chip just runs way too hot in a typical StickMiner configuration.  I do hope the BE300 and others will prove to be more fit for the purpose.. my post is getting stale ;)

Interesting to see if some of the newer sptech or bitmaintech chips could be converted to Stick miners just so that people looking to learn about bitcoin mining have a cheap way to get involved. Asicminer newer chips possible as well. Can you get them in quantity to make a small run viable for the builder?

Mind you Bitfury is not going to give up their chips or miners to people playing around anymore those days are done given their in house development and move to a B2B model. They don't need the community anymore I guess.

How hot is the BE200 miner with a fan?
If it could cool down with a fan, it might be a possibility..

Are there any news about a new Miner?

Or has anyone BFx2 Bitfurys to sell?

that usually happens if:
1. driver is not installed
2. not enough power per port

What hub are you using?

hi goodney mind telling us how many of the bfx2 stick miner you made ? hundreds ? thousands ?
not mean to mind in your business simply curious for the history of bitcoin mining.
