If your PSU has multiple rails one of the rails will be on the PCI-E 6/8 pin connector.

What I do is chop a molex off on an overloaded rails and wire it up to the PCI-E.

The problem with dupes is that they afect your hash rate and you can get false feeling that it works better when do not take in account rejects. Anyway watch technobit site for update fixing this it should be released soon
Once again rejects will be always there even dupe issue is fixed that is the way it works with other boards/vendors also. There is no workaround for this
And finally precise formula as suggested by kano

Paid shares
cgminer-api devs
[ASC1] =>
(
   [ASC] => 1
   [Name] => HEXc
   [ID] => 0
   [Enabled] => Y
   [Status] => Alive
   [Temperature] => 0.00
   [MHS av] => 22030.36

   [Utility] => 0.57
   [Last Share Pool] => 0
   [Last Share Time] => 1389967128
   [Total MH] => 414125041.5510
   [Diff1 Work] => 96422
   [Difficulty Accepted] => 104448.00000000
   [Difficulty Rejected] => 524.00000000
   [Last Share Difficulty] => 512.00000000

   [Device Hardware%] => 1.2747
   [Device Rejected%] => 0.5434
   [Device Elapsed] => 18798


To be more precise as ugested by kano

2^32/[Device Elapsed]*[Difficulty Accepted]/10^9

My score is lucky though i rebooted cgminer but it shal give you almost same result as the 21.61 GH/s * (1-R/A)

Thanks for the calculation.

Miner been running for 3 days, so pretty accurate. I don't believe I have power issues either, so maybe a problem with the pool rather than the miner itself.

Yes it does for sure written in Changelog
If you have nanos use --enable-hexmineru (make sure stock bitfury is disabled though) works great otherwise compile and  run two instances with appropriate devs enabled only
Or better for other devs just compile stock version

Now i managed to compile it with the exact version pulled from the git repository and autogen but is it really true, that the hexminer patch breaks the butterfly support? So i have to compile 2 versions and let them run at the same time?

Bye
Michael

Same shares submitted to the pool twice - you should see them like rejects R
you can calculate your actual hash rate as follows:


21.61 GH/s * (1-R/A)  =  PAID hash rate
Have in mind that Rejects are caused because of stales also.

for instance i mine at bitminter and my rejects are below 0.5%. It is normal to have rejects this is unavoidable

To make accurate calc run your miner for a day to avoid variance and be 100% sure that there were no pool/network issues

What exactly are dupe shares?

I seem to have quite a few of them - 21.61 GH/s   1619976 (99.82%)   2906 / 10924 / 0

That is why i am making my molexes by hand 2 mm wire crimp+soldered pins   And i am making sure that from PSU site i have at least 2mm wires yellow + 2mm blacks

Apart of the jokes no serious

Lack of steady 12V to the board explains why it was disappearing BUT there is a bug which submits dup shares which is fixed and under testing. So watch technobit site for updates dup shares were caused because of voltage problems


 

one rail is 19A, so only 2 board(2 X 9= 18A) per rail.
Read carefully what i post there, i am talking about per rail not all PSU.

Yo, but i have 4 rail ^^

Cause one HEX16C used 9A 

Hey!
Yes u have right, the current PSU have 4 rail from 12 volt, and every rail can handle 19A. Why do u think that they can only maximum 2 board handle?
Today arrives the nwe PSU what i ordered.
There is:
Cooler Master GX 750W RS-750-ACAA-E3
http://www.xbitlabs.com/images/cases/psu-550w-850w/p19.jpg
One rail 60Amper. I would cut all other cables from it, and make for every board separated cable with molex. I hope thats help with.
The current USB HUB (xtrust) is today died. I have now a old HUB with 4 ports (Koenig USB HUB, its active, but i dont plugged in the power) . Its seems be good, with the Gigabyte PSU make power for 3 boards, and the boards is connected now to the 4 port usb hub.
Now work es nice, here is a screenshot:

How about increase your worker difficulty to 64.

And your PSU, http://www.guru3d.com/articles_pages/gigabyte_odin_plus_700w_psu_review,2.html said that your PSU is four rail.
Each rail can supply 19A(HEX16C use 9A). This mean maximum 2 board, but personally i won't let the regulator run 24H on 90% load. I am more prefer to spread the load on four rail.

11.68 V is very bad you know, maybe the regulator already overloaded.

For best efficiency, it's best to choose single rail PSU.

Are you sure that the patch work??? There must be a error message appear when run the patch.
There is no hex16 added in your summary. You must be use wrong patch for wrong cgminer version

For cgminer 3.8.5 afe7710858e4ce28bb60f6ae6e167a18d687634f.patch
For cgminer 3.10.0 87f0213112a3c69e2c55160b9c674b9de2cde996_u.patch

Hi, for those of you who haven't received their orders, here is the detail of my order:
2013-12-01 -> order paid
2014-01-10 -> order shipped
2014-01-16 -> order received at home (France). BTW, Speedy doesn't deserve its name 

If orders are processed according to order date, you can estimate when yours wil be at home.

Marto, a different order labelling will help at least in communication.
You will be able to post fast and reliable status update of orders, something like this:
HEX16B-0000001 to HEX16B-0000256 Shipped today
HEX16A-0000001 to HEX16A-0000025 Going through testing
HEX16C-000001 to HEX16C-0000054 In assembly process

Note the bold "c" that will help you avoid confusion during shipping and inventory between the 2 generations of Avalon boards (Yes, I received a Gen 1 miner instead of a Gen 2 miner).

These a simple ideas, but they should help you a little.

Just as a sidenote, I'm employed on process improvement (Kaizen, Lean manufacturing) in aerospace, and some little tricks like the ones I gave here can really improve reliability and productivity at almost no cost. It works in bigger companies, but from my experience, it works even better on small ones.

First autogen.sh dude instead of configure then make the. BFL and avalon will not work anyway so you can skip them and you can build 3.10 patch is available in technobit site

Hi,

i downloaded cgminer 3.8.5 and patched it with the patch from technobit. Then i did a configure with ./configure --enable-bflsc --enable-avalon --enable-hexminerc

When its done it shows me:

I don't see a hexmierc option and the miner, after i did a "make install" does not know the hexminerc options ->

 cgminer --hexminerc-voltage 900 --hexminerc-options 16:540
 [2014-01-16 16:12:09] cgminer: --hexminerc-voltage: unrecognized option

can anyone help with this?

Thanks Michael

Okay but i go too now. I dont do now nothing just run it. I think the PSU would the problem. Tomorrow arrives a better PSU to me.
Im from Hungary, but i speak good German too.
Thanks for help:)

Ok start with removing separate ~1A 5v power supply that shall do the trick with common ground
If hub is crappy and Pi needs more power just gently cut usb Pi cable cut red wire +5V and spike it with Molex red from PSu or whatever you find is convenient for you
Are you in Germany?
PS: I am going dude see you later do not forget to test your boards one buy one first to see if all three are OK

The RPI can power through miniUSB and normal USB too.
This is a Model A, i have only one USB port and i dont have ethernet.. i need the wifi.
The HUB is powered from the RPI AND from the hex16a2 boards. From the Hex16a2 miniUSB connector i can have 5v.
The RPI is powered from a seperate ~1A 5v power supply AND from the USB hub.
