Bitcoin Forum

About 4 months after marto74 announced (https://bitcointalk.org/index.php?topic=212031.0) his assembly service for avalon chips I've got my fully assembled bitcoin miner called HEX16A.
The board is based on TechnoBit's design for 16 chip miner, ordered first week of August for 49,30€ from their online shop.

http://t.imgbox.com/ade3mGcd.jpg (http://imgbox.com/ade3mGcd) http://t.imgbox.com/adrrPGYl.jpg (http://imgbox.com/adrrPGYl) http://t.imgbox.com/abyNQsOC.jpg (http://imgbox.com/abyNQsOC) http://t.imgbox.com/acsu8bsV.jpg (http://imgbox.com/acsu8bsV) http://t.imgbox.com/aczIeOGe.jpg (http://imgbox.com/aczIeOGe)

My first impression of the board is the massive heatsink that covers the entire backside of the board, together with the huge filter capacitors close to the chips. Those two factors and the improved power supply module helps for the great overclocking capabilities that HEX16A provides. It can easily be clocked to 500Mhz with less than 2% HW errors, that makes the board one of the best on the market.

TehcnoBit provide their version of cgminer with support for the board and adjustable core frequency and voltage.

http://t.imgbox.com/abzSXnR1.jpg (http://imgbox.com/abzSXnR1)

Here is a chart with the performance of HEX16A, keep in mind that the consumption is at the wall and includes PSU CM RS450-ACAA-D3, measured with APC SmartUPS.
  
http://i.imgbox.com/adkRbJeg.jpg

Even that 500Mhz per chip is a great achievement the power drawn by the board is quite serious. If we take into account the PSU's efficiency of 85% it turns out that the board consumption is around 105W or a current of ~8.75 A. In my opinion this kind of amperage is too much for a single wire and a molex connector which by the way according to wikipedia has a max current of 11 A/pin (30 °C rise).
For comparison, ASICMINER's Blade (old version) overclocked to 13GH/s drawns 115W at the wall with the same PSU, that makes 8.84W for GH  

http://t.imgbox.com/acnSWozl.jpg (http://imgbox.com/acnSWozl) http://t.imgbox.com/acsnP4uG.jpg (http://imgbox.com/acsnP4uG) http://t.imgbox.com/acy3MscL.jpg (http://imgbox.com/acy3MscL)

HEX16A is equipped with 92mm cooling fan but it is lacking temperature control for it. If you value your comfort you can easily switch the fan's connector from 12 to 5V. Of course speeds higher than 400Mhz it is recommended to leave the 92mm fan at full speed. The fan itself is a SUNON EE92251S1-0000-A99 and has a great air flow of  51.5 CFM with low noise levels even at full speed: 34 dBA

http://t.imgbox.com/adlh9RrQ.jpg (http://imgbox.com/adlh9RrQ)

At their online shop TechnoBit offer a preflashed TP-Link TL-MR3020 (http://technobit.eu/index.php?id_product=37&controller=product) with the special version of cgminer ready to use with HEX16A.

 http://t.imgbox.com/abygwNoz.jpg (http://imgbox.com/abygwNoz)

The router is based on OpenWRT firmware and provides easy to use interface to setup your mining parameters. The limited amount of RAM on the TP-Link has forced TechnoBit's developers to turn off the WiFi completely. Marto confirmed that the firmware will be open source and ready for download on their support site, so it would be great if we can manage to turn WiFi back on and use it as a client for a wireless connection.

Since this is a linux based router you can SSH into it and access the screen of cgminer with screen -r

Pros:

• Price
• Overclockable to 500Mhz
• Stackable
• Cooling
• did I mentioned price :)

Cons:

• Single molex connector, even that it's not a problem at lower clocks

Conclusion:
I'm very pleased with this board, it has great overclocking potential at affordable price which can help for a faster ROI in the first months. I'm looking forward to see other products from the based in Bulgaria company TechnoBit, they are already working on BitFury and BFL based boards .

Edit:
cgminer / hexminer tutorial: https://bitcointalk.org/index.php?topic=303538.msg3371198#msg3371198

Nice!

Where did you get the CGminer or a plugin for CGminer?

Nice post.
Great evaluation!!!

It is build in the router's firmware, AFAIK the sources will be available for download on Technobit's support site.


Thank You :)

Is there a setup guide for these miners directly without the modem?

i would be happy to donate some mBTC for the guy who does this (my HEX16A will arrive next week probably)

Thanks for sharing! Now, I regret not buying when they were available.

Ah, well: 6 different pre-orders from 3 diff. mfgs. should be more than enough for now, right?

Very good looking!

Still avalaible on : http://technobit.eu/index.php?id_product=21&controller=product (http://technobit.eu/index.php?id_product=21&controller=product)

But you need avalon chips...

With all the refunds...seems pretty hard to find now.

It will be straightforward  when the cgminer version for windows is ready for download, no need for tutorial. I'll update this topic with more info when available.

This is actually the first Klondike - based design to be fully confirmed working with 16 chips & 400Mhz. Great job Marto & team

Nice review :)

Wrong!
look deeply into cgminer shot it says 500 so fully confirmed it works even better ;)

playing around with the overclock :)
480Mh/z @ 1440mV - 7.50Gh/s - HW: 1.63%

http://i.imgbox.com/adyI7K3q.jpg

Impressive work! Yet the best Avalon based miner available.

Very nice !

Hopefully, this spells good news for the Klondike and derivative designs that sprang up from it.

Looks like the various problems are on their way to being solved.

In that vein, is the source code available that the firmware image was built from?  In particular I'm after the changes to cgminer.

I already bricked a WR703N somehow trying to flash the image onto it.

The patch for cgminer is available for download from the technobit's web page.
link (http://technobit.eu/index.php?controller=attachment&id_attachment=5)

I've done it for Windows, but the there are some problems with the USB driver and the device is not recognized by the cgminer.

I repaet.

If anyone can create a manual for the technobit HEX16A, he will get some donations ;)

needed manuals:

no cgminer for windows or at least I can not make it work (4 now), there is a bounty for cgminer for Windows on the Bulgarian Bitcoin forum: http://bitcoinbg.eu/forum/viewtopic.php?f=6&t=377

Happy Hashing :)

Guy's,
Is the 2GOOD howto usable for you?

I have my miner in hand, and trying to configure now :)

A question for the Linux specialists.

When the HEX16A is started without the SUDO command, you get following errors ;


Is there a way to get rid of these errors by giving the necessary authorities to a folder, file, etc. ?

Update:

After some research on the internet i found the solution.

In cgminer folder you'll find a file named '01-cgminer.rules'.
Add following line into file '01-cgminer.rules' and copy the updated file to /etc/udev/rules.d


After a reboot of the raspi, i was able to start cgminer without the SUDO command.

I cant download the mining software there ?
Any other download links ?

My Windows does have problems communicating with the device and installing the driver.
Is it possible to load this drivers manually ?

Regards

Plugged it into my other computer and it looks like the usb driver works there.

Now my problem is that i dont get the program working.
Can anyone please post a picture with youre options how to run this thing ?

The Straum options does not work for me either.

Is there anyone who is possible to convert the cgminer version to windows ?

Regards

Do yo have Teamviewer
If so give me log and pass
connect the boards and I'll show you

First, .... a big Tnx to 2GOOD (https://bitcointalk.org/index.php?action=profile;u=23223) for explanation in first post...

Miners work well under ubuntu x64

here is my apiary :) :

P.S. - i have some boards not working still

Will ask Marto74 for help these days...

WBR, DebeliaMark, BG

^^^^^^^^^^^^^^ nice rig  ;D

Can someone confirm if I will need to purchase usb cables or if they come with it. If so what type of usb are they?

Thanx

If you ordered thet in our shop you have.
If not it is like this :
http://www.ebay.co.uk/itm/1-8M-Meter-HI-SPEED-USB-2-0-CABLE-LEAD-A-MALE-TO-MINI-B-5-PIN-CAMERA-PC-/310555329418?pt=UK_Computing_USB_Cables&hash=item484e8a438a (http://www.ebay.co.uk/itm/1-8M-Meter-HI-SPEED-USB-2-0-CABLE-LEAD-A-MALE-TO-MINI-B-5-PIN-CAMERA-PC-/310555329418?pt=UK_Computing_USB_Cables&hash=item484e8a438a)

I did some (hopefully helpfull) tutorial how to setup the miner on W7.
Sorry for the bad sound quality, but i does not have a better one.

@2Good: Would be nice if you could post the video in your tutorial section.

Regards.

Great

I have 5 of those, i wonder if i can make them work under MacOS
(I mean w/o the router, directly usb on the macbook)

Has anyone tried it? If yes
any guides?

You have to compile cgminer yourself. Follow my linux guide with this one:
http://andarazoroflove.org/compiling-cgminer-with-scrypt-on-osx-mountain-lion-for-gpu-mining-ltc/

as you use mine ./configure command.

Good Luck :)

Well, fast response, thank you :)
Will report back

I have 3 Hex16A boards, they are running stable for about a week now. Getting them installed wasn't easy as a total Linux/Raspberry/programming noob, but thanks to all the great tutorials here I got them mining.
BUT, they are only putting out about 4.3GH/s instead of 7GH/s.
I'm using a Pi with minepeon and the patched cgminer.

When following the tutorial it says:

add following lines to opt/minepeon/etc/miner.conf

"hexminer­options" : "16:450",
 "heminer­voltage" : "1390",

If I do this, nothing changes. Maby I'm doing something wrong I don't know.

I open a session in Putty
I type: nano opt/minepeon/etc/miner.conf
and add the lines
https://lh6.googleusercontent.com/-onBtE8tVA1Q/Urag57W51SI/AAAAAAAAAAg/Zwi24QfkUeM/w672-h423-no/cg-miner+add+lines.jpg
I save the file, reboot my Pi and restart the miners, but nothing changes...Am I adding the lines at the wrong place, or anything else I'm doing wrong?

are yu sure you saved the conf file?
Maybe you need to use the "sudo" command?

When you changed the file, ctr+x and than you need to confirm the changes by pressing "y"

Yes, I'm sure I saved the file.
Just tried a sudo nano, but still no changes, they stay at 4GH/s...

You should start cgminer with:

sudo ./cgminer -c /opt/minepeon/etc/miner.conf

this way it will read the conf file.

I start cgminer like this in minepeon:

 #!/bin/bash
sleep 10
/usr/bin/screen -dmS miner /opt/minepeon/bin/cgminer -c /opt/minepeon/etc/miner.conf

when I enter:

sudo ./cgminer -c /opt/minepeon/etc/miner.conf

I get command not found.

thanks for the tutorial 2GOOD!

After a substantial amount of time on this forum (and others) I tried to get my Technobit HEX16 to work on a Raspberry. It works on a Windows machine in combination with HEXminer but I am not impressed by it's stability...

Being a total newbie on Linux I followed several "tutorials" I found on the fora. The one I had the "best" result with (and being quoted by others as working) is this one described by you (BIG thank you once more for that one 2GOOD, BTW!).

But after I:

sudo apt-get update

and I:

sudo apt-get install autoconf yasm pkg-config make libusb-1.0-0-dev libusb-1.0-0 libcurl4-openssl-dev libncurses5-dev libudev-dev

succesfully, then I:

Download the build cgminer-hex16a-3.6.1.tar.gz with: wget https://dl.dropboxusercontent.com/u/8082585/cg/cgminer-hex16a-3.6.1.tar.gz 

I extract the archive with: tar -xvf cgminer-hex16a-3.6.1.tar.gz

But the tutorial then says to "Edit cgminer.conf - it is preconfigured for speeds 480Mhz @ 1440mV"
I have no idea what to do so I type: "edit cgminer.conf" and all it says is:

Warning: unknown mime-type for "cgminer.conf" -- using "application/octet-stream"
Error: no "edit" mailcap rules found for type "application/octet-stream"

I change directory by: cd cgminer-hex16a-3.6.1 and try again, but with the same result

Assuming I need some sort of editor to do this AND assuming that the preconfigured file should be OK for now I run cgminer with:
sudo ./cgminer -c ./cgminer.conf

But I get this message:
./cgminer: 1: ./cgminer: Syntax error: word unexpected (expecting ")")

Undeterred I continue with the tutorial (thinking maybe I should run the patch before this actually works), and I: cd

Then I: apt-get install autoconf libtool libcurl4-openssl-dev libncurses5-dev pkg-config yasm make

AND HERE IT STOPS FOR ME WITH THE MESSAGE:
E: Could not open lock file /var/lib/dpkg/lock - open (13: Permission denied)
E: Unable to lock the administration directory (/var/lib/dpkg/), are you root?



Just to be complete, the rest of the tutorial says to:
wget https://github.com/ckolivas/cgminer/archive/v3.6.1.tar.gz
tar -xvf v3.6.1.tar.gz
cd cgminer-3.6.1
wget https://dl.dropboxusercontent.com/u/8082585/cg/cgminer_3_6_1_rev_fe5da9672767e18116444dad18db54638936490a.patch

./autogen.sh --disable-opencl --disable-adl --enable-avalon --enable-hexminer --enable-bflsc --enable-icarus
make
sudo ./cgminer -n
to check the HEX board is detected

Could you please help me get this Technobit HEX16 on a Raspberry with a clean install of Raspbian / Debian to work?

Cool, thank you for taking the time to reply.

It worked! And I go through the rest of the tutorial. At the end I check if the HEX board is detected with:

sudo ./cgminer -n

and I get the confirmation: 1 known USB devices

Now I return to the "run cgminer with:"

sudo ./cgminer -c ./cgminer.conf

But I get the error: unable to open ./cgminer.conf: No such file or directory

OK so i cd and I cd cgminer-hax16a-3.6.1 where there is such a file.

I try to copy it by: cp cgminer.conf /cgminer-3.6.1

But no luck: cp: cannot create regular file '/cgminer-3.6.1': Permission denied

Ah; add 'sudo'... No error, but also no file in the directory cgminer-3.6.1 ?!? Also no file after 'ls' or even 'sudo ls'...

I know, I said I'm a newbie... Sorry!

But: please help!

Problem solved!

I edited cgminer.conf file - to include my miner-worker details - in the GUI and copied it (also in the GUI) from the directory cgminer-hex16a-3.6.1 to the directory cgminer-3.6.1

In the directory cgminer-3.6.1 i ran cgminer with: sudo ./cgminer -c ./cgminer.conf

Works like a charm, even with another Butterfly labs miner connected next to the Technobit one.

Thanks Souspeed! (I sent you a "virtual drink" through "the block chain", cheers!)

Super,

Just an advise use latest cgminer 3.10.0 the patch is available on technobit site. You will do it like piece of cake. Apart of jokes 3.6.1 is buggy :) it is highly recommended to switch to latest

In the mean time, this is what worked for me, both with the Technobit as well as the Butterflylabs ASIC (apart and together):


Happy hashing!

The HEX16A2 can mine any virtual coin or can mine only bitcoin?

ALL Bitcoin ASIC devices can mine any double SHA256 coin, they can NOT mine scrypt based coins.

I have some problem... i cant mine zetacoin...

If i go to bitcoin there is no problem
https://i.imgur.com/MtjPLUG.jpg

But in p2pool.org - zetacoin... dont work
https://i.imgur.com/S3kfAR0.jpg

Does anyone know why?

I could not see a download patch for 3.10.0, does the 3.6.1 patch work on 3.10 ?

not that it matters as am still waiting on boards, but nice to know should they ever turn up..

Patch for 3.6.1 wil not work on other version or vice versa.
Patch for cgminer 3.10.0 that uploaded by technobit 0.1.5 (http://www.megafileupload.com/en/file/487995/0-1-5-rar.html)

or

Uploaded by me that work with wget command https://www.dropbox.com/s/5fgzi8sux0qltlm/87f0213112a3c69e2c55160b9c674b9de2cde996_u.patch

Thanks Zich, its good to have for next time I compile CG.

;D

hello please I need help setting up my maquinas.pueden explain?

The link to the download of hexminer doesn't seem to be correct anymore.


My hexminers seem to keep disconnecting from USB constantly... Not sure what's going on here...

Anyone get an issue like this?

Link HEXMiner 1.0.0.3
 (https://technobit.eu/index.php?controller=attachment&id_attachment=29)

Yes, i had similar experience too. If you insist to run the miner on windows, you can install linux on virtual pc then use cgminer  :)

Had same experience under windows, solved it by using ubuntu.
Works great now and stable.
oh, and using version 3.6.1 of cgminer, rest of versions i could not get it to work with.

I have some of these running and they need constant monitoring as they randomly stop mining throughout the day. I have the latest cgminer with patch but same issue and the only way to get them back is reboot the pc. Any ideas? It is a huge pain in the ass.

Mine is connected through an older version of cgminer and a Raspberry Pi, not a PC (see above).

Has been hashing away ever since. Didn't hang once....

RasPi is more power efficient too (just at the same PSU - but then 5V - as the HEX16 is connected on 12V), just a few Watts (instead of the 100's a PC uses).

I'd recommend to get you a RasPi for a few bucks...

Good luck with it anyway!

TPLINK TL-MR3020 more cheap then  :D

Thanks for the tip! But how does that work then?

1. Default IP address of mr-3020 is: 192.168.0.99/24 LAN only. Wireless support is completely removed. The reason is LACK of RAM + some usb issues reported in the forum
2. There is no root password configured – that is the first thing to be done
3. Make sure that your computer has L2 connection to router with IP address from same subnet – 192.168.0.0/24
4. Configure your network under Network Interfaces. There are two options (Static IP /Mask GW and DNS or DHCP client). PPPoE is not included in the build. We suggest to use static IP address. Change your timezone settings. Do not enable NTP client. Reboot the mr-3020. Wait one minute. Make sure that mr-3020 shows current time. Do not proceed forward if the time is not correct. Otherwise cgminer will never start!!!   
5. Configure your pools, workers and stuff under Cgminer Configuration page
6. Press Save & Apply . Wait at least 5-10 seconds for cgminer to start/restart
7. All done – Take a look Cgminer API log. You might find some good stuff inside
Some notes for advanced users:
1. cgminer is executed in detached screen session. You can always ssh to mr-3020 and attach the screen with screen –r. Detach it with CTL+a+d. There is nicely formatted cgminer  ncurses output flowing. Be careful with screen detaching – if you mess it up it will kill your screen + cgminer and you will have to restart it manually. Every time when you detach a session something similar shall happen

root@HEX16A:~# screen -r
[detached]

2. All unnecessary services are disabled by default. This applies to firewall and all corresponding kernel modules also. If you know what you wana do you will have to uncomment desired kernel modules located in /etc/modules.d/. They are commented out to save RAM.
3. There is ovpn support package installed by default. If you wanna use it please uncomment tun module located in /etc/modules.d/30-tun
4. API stats notes:
a. No Matching Work is not a hw error. It occurs when cgminer detects new block or during startup mostly. It has been contented as a reference only.
b.  Reset Count – should be low. Let me say 3-4 resets per day. When reset occurs only 2-3 work results are lost if they are lost at all. When higher values are observed check your cooling + overvoltage+overclocking
c. USB Hardware Errors – they are added to HW errors stats. In general these are usb readings with bad checksums
d. [Chip1-16 Nonces] how many nonces a chip has found. Useful in case of dead chip and so on. Note variation (+-)between chips nonces is absolutely normal. Watch for obvious differences and zeros.

The cgminer + current build + HEX16A mining board is super stable. There is no need of cron restarts and such stuff. Cgminer hotplug is working fine on i386. Unfortunately it does not work with mr-3020 + openwrt. The hotplug support is disabled by default: --hotplug 0.

Enjoy!

Cool, thanks Marto74 (as so often)!!!

Fixed thanks

I want to produce 1T or 2T machines, can provide what help?

Marto74, if you need webspace to host your downloads, I can provide it to you or just as a mirror. I have a server in UK and Germany.

Does this miner require the router at all for windows? The only thing stopping me from buying this for hobby mining is the fact that it requires this MR-3020 router, but if it can work with Windows WITHOUT this said router, I will buy it.

It works without the router, it's just so much easyer using the TpLink. It realy makes the miners plug&play devies.

And you will struggle running HEX16A on windows since you can not use cgminer or bfgminer. The only available is HEXMINER.
Or use virtual pc to run linux then compile cgminer with patch from technobit.

Honestly I bought this device(used/second hand) to mine solo Bitcoin. No point in mining in a pool for less than $0.5 in profit. Yes, I know diff is 4 billion and going even higher bla bla, I've been around since 2011 when Bitcoin was $3, I know the probability of finding a block is zero with this device, but I still want to do it.

Don't they have something that looks like this that does 60 gh/s?

Here's a little bit you guys probably didn't know. HEXMiner is written in C#, grab any decompiler and you can tweak the source code if you have any C# knowledge.

My Hex16a1's are not realy happy with the latest firmware 0_3_0 for TpLink mr3020, I have 4 on 1 router and within 30 min 3 of them drop out every time.
Should I downgrade back to previous version, or is there another way to get them stable on the current version?

There is other issue USB hub or power
The latest fw is 3_1 btv

I upgraded to 3.1, Same problem. I'm using the same PSU (Corsair 1000W) and powered usb-hub (Belkin 4 port) as I did before and I never had this problem...

oh... I was thinking you are talking  abut coincraft my bad dude ;)
Yes this happens with latest fw they come to zombies and recovering fast
It should not affect your hash rate for sure. If you are not happy to have them come and go just downgrade

I just added a coincraft, that one is working great.
It would help if slush pool would solve a block, so I can see the more or less right statistics.
In the API-log of the mr3020 are a lot of miners not enabled and status sick, so many that they are not all displayed.
I think I Will downgrade for the one mr 3020 with only Hex16A1's connected.

Thanks for your fast reply Ioshia

how many of the hex16a devices can be hooked up to just one TL-MR3020 router with preloaded CGminer /dd-wrt for HEX16 board ?

I have reached 7 10 should be ok also
but make sure you are using common PSU ground otherwise shit will happen

alright thanks for the info, was just looking at other options i might need.

I am trying to run my hex16a2 on my windows 8 Desktop PC with the newest hexminer software and miner_proxy with usb drivers. Every time i press start on the mining the console will show it is connection then it fails and says the driver need to be up dated even though i have the most recent updates.

Is there a cgminer compiled to run on windows and support the hex boards? this would be very handy

Buy a tplink dude and forget
I can not give much help with windows
but there is one look at 2good topic.
It is a mess with cgminer and windows zdiag drivers and so on...
tplink will pay the electricity for a month and it is plug and play :D

You can run hex16a2 with cgminer for windows:

I am running a total of six hex16a2 miners with a windows 7 laptop.  All connected to a generic 7 port USB hub.  It did take me a while to get it configured to a point where it runs stable.  I still reboot the entire mining system once or twice a day in order to maintain stability and performance and set up the mining pool to email me whenever the miners go inactive so that I can troubleshoot it as soon as possible.  Once you figure out how to keep it stable, downtime becomes infrequent.

With this many miners I opted for 2 different power supplies.  You can run two miners from each branch of the power supply, however if you do you will find the wires get very hot.  So I set up mine in such a way as to only run one miner per branch. Proper wiring is important.  With the older boards that had 4 pin molex connectors, I found that not all 4 pin connectors fit easily.  The classic white ones were fine, but the newer black ones could be difficult to push in.  If you ran into a flakey connection, you can usually fix it by using an 4 pin molex extension cord.  You can use the SATA connectors by using a SATA to molex adapter cord.

For the newer boards that have a 2 wire power supply, I think it is a good idea to put a cable tie around the closest bolt to hold the wires in place so that your power connection cannot be tugged out by pulling on the cables.  I used the PCI-E power connector from the power supplies to power these boards, and secured the connections carefully with electrical tape.

The USB cable running to your computer should be secured to something in such a way that there in now weight on the USB cable.  A flakey USB connection seems to be a major cause of crashes.

The newest hexminer driver for Windows should download automatically.  At first I tried to manually download the drivers that were recomended by the seller, but then noticed that a newer driver was available.  Driver version 5.1.2600.7  Date: 06/12/2012  Microchip Technology, Inc.  It worked better than the older driver I tried at first.

It can be tricky to get these miners properly configured with your PC environment.  I have run into problems with Windows Firewall and various antivirus software programs trying to block or shut down the miner proxy and the Hexminer software.  Some antivirus identify Hexminer program as a trojan virus and automatically delete it from your computer.  So it is important to set up some exceptions in your internet security so that these programs will be permitted to run unhindered.  The computer you have chosen to run the miner on will be pretty much entirely dedicated mining.  If you run other programs it can interfere with mining.

Power setting in windows set to maximum, and never allowed to go in hibernation mode.  Windows updates must be set to manual, so that your computer will not suddenly reboot in the middle of the night after installing new windows updates.  These are things that will cause downtime to your mining.

You can run them with cgminer and avoid instability:

Since I have never used cgminer before, I would need to familiarize myself with the program.  I followed the instructions and set it up to run one of my miners, but I am receiving the message that no devices are detected.

Please comment in the cgminer thread!

About the problem try reboot or at least replug of the devices.

Maybe you download wrong version.

The one that support HEX16A is: https://dl.dropboxusercontent.com/u/8082585/cg/cgminer_technobit_win/cgminer-hex16a.rar

But if i may suggest, as loshia said, use TPLINK TL-MR3020 as host. It's cheap, use small power & easy to configure.
Check it out here: https://bitcointalk.org/index.php?topic=476326.0

Thank you worked very well.
Do you know the settings for voltages and watts by chance for the cgminer config file for regular speed and over clocking?

Here is the HEX16A2 review:
https://bitcointalk.org/index.php?topic=355323.0

I run mine at 1200mhz / 950mv => 19GH The power consumption should be bellow 50W

so what would i put in this following section of the configuration.config file if i want it running at 22Gh/s
or is this already set by default?

I am using a combination of Corsair CX750M and a Thermaltake smart 650w power supplies to run 6 hex16a2.  According to the Killawatt, it is taking about 257 watts to run, so that averages out to 42.5 watts.  I am running mine at 1530mhz / 1020mv.  However I was registering a much higher power consumption before when I was just using the cheapest generic power supplies I could find.  I wonder if these new power supplies are really that much more efficient, or if maybe my killawatt isn't giving me a proper reading because I have the two power supplies connected to a multi outlet adapter plug.

So far, I seem to be generating less shares with CGMiner than I was using HexMiner.   I was sometimes seeing up to 110,000 shares on certain shifts with HexMiner, but only topping at 90,000 using 6 miners.   

That's was HEX16A setting, for HEX16C:

do not use "set_default_to_8" : false,

If i remember correctly, my HEX16C use about 9 A on 12V rail, so that's was 108 watt.
That's why she is retired already.

The fellow who was selling these was doing brisk business for a while, however the sales have trickled to a slow crawl.  People are probably realizing that getting a full return on investment from these is not very easy.  Especially when you consider that the original price was around $200 per miner, then eventually half that price.  And the cost of electricity, like you said.  To try to compensate, I have rolled much of my bitcoin earnings from these miners back into cheaper cloud mining, to get to the point where most of the mining I do is in the cloud.

I notice there is an overclock chart for the Hexminer 16A

are there charts to overclock the 16B and 16C miners elsewhere on this site if so I have been unable to locate.
I also tried to get from technobit site could not find so I requested the charts I have yet to get a response, ( about 2 weeks)

You can check my reviews for common settings and charts:

Thanks will play with this a bit and see what happens

i got my Hex16A to run on 8+ ghs but over two min gets weery hot so didnt do testing on HW erors clock 530mhz 1550mv.

I shorted that yumper on the 5v rail so it gets power directly from psu.

Anybody did any testing how high can i push avlon first gen asic chip 

Thanks
