Hi emdje, is possible to run 2 session of cgminer in two detached console one for blade using the ssh connection?

Thanks in advance W_M

No it is not, the pi is connected to the control board which in turn is connected to the blades. As far as I know you can only control the control board.

Allready tried some Grin

, but unfortunately it doesn't take yet, it switches to 1000 MHz Embarrassed

Emdje, any chance of an underclockers version?
I've undervolted my A2 and a few blades are already at 1000MHz but elec costs are now approaching revenue. I need lower frequency to get the voltage lower to extend its life a bit more. If you could add 50MHz or even 100MHz steps down to 700 or 800, that would be awesome

Mind sharing how you were able to lower voltage on the blades?

Lowering the frequency does nothing to the voltage (does lower the strain on the chips, thus lowering the current), so I assume he soldered some resistors with lower values next to the voltage regulators.

But to answer the first question. I will look at adding some more option on the lower end in the coming days. Will test it out and when it works I'll put it up.

Ok - so what is recommended for my A2 Terminator 88Mh/s units?

I currently have the "InnoSilicon webGUI" software installed on them - which runs well and allows me to over clock to 1280 (or at least that is as far as I've gone) -- although I typically just keep them at 1200mhz.

Is there an image I can just copy onto the the builtin controller (I guess it is a Raspberry Pi) and it boots up with the new software / interface? Something that doesn't really need any special configuration.

I'd rather stay away from too many command lines -- as I don't want to make a typo and then they are unbootable.

Thanks for any direction on this -- or if it is even worth it?

Appreciate it!

If you want more overclock options (like values between 1200 and 1280, and above 1280) then you should go for version 3.0. This has extranonce support as well, providing more stable hashing at for example nicehash. You don't need to use command line stuff, just the webinterface will do.

Apparently minereu has firmware that works with it:

Quote from: minereu.com on May 30, 2014, 09:39:58 AM

The MinerEU firmware has been updated and is also reporting how many cores and temperature of the cores now. please update

new miners will still have 6 module but each pcb panel will have 12 chips instead of 8 chips. which offer a total hash rate of 120M

Maybe you can send a pm to them. I search for a link to firmware for the 110MH terminator but could not find it.

Thank you but my miners are 5 blades not 6 so I don't think they are the same. The one I have are LTC LIMITED--T SERIES.

I don't know that version, and I unfortunately have no suggestions on which version you could use. You could try the one for the NEW Mini terminator, but it is not stable (but coded for more chips per board). If that does not work you can try the newest version 3.0. But no guarantees it will work (it will NOT damage the miners though).

So I'm alittle embarrassed to say this -- but what does "Extranonce support" give you?

I have some A2 Terminators 88Mh/s. Does this new image provide more efficient hashing with any pool? Or just certain pools that support this feature?

What are the benefits? Is this something that would work with my miners?

If there is an easy to read thread about this then feel free to point me in that direction.

Thanks!

It makes for example the change between jobs on Nice/Westhash go a lot faster, without the reconnects. I don't know the deep technicalities.

in your opinion is simple to reconfigure your image to use the web interface to comand gridseed blades?

if i use your image and change the cgminer with a cgminer for gridseed its work?

i know you develop for innosilicon but i have 2 gridseed blades and web interface of a2 is the best to use.

Gridseed is very different from A2, for example the setting of the clock frequency will not be the same. If you want to try, you would need to adapt the index.php as well (the webinterface), because the command that is send to cgminer is send from there, and that command must obviously be different than that from the A2.
And there is another copy of cg miner in /usr/local/bin

Might be better to use Minera for your purpose: http://getminera.com/

Any idea where I can get orginal a2 110MH version firmware? my card got corrupted and have no firmware. Im running currently OC ver 3.0 but my blades turn off and on and miner is very unstable. I have tested all other firmwares and its basically the same so need the original.

zoomhash sent the sw to me. I could not find it as well. PM me and I can send it to you.

hy emdje i'm using your "Overclock version 2.0 by Emdje" to mine on 24 different pools at the same time with load-balance activated and work well.

do you know how to activate the extranonce?

i use --load-balance, is there a command like --extranonce or similar working?

thanks for all

i have an a2 mini 8chips 2 blades.

is the 3.0 ok if i use it?

Glad to hear it works well. The version with extranonce subscription is version 3.0.

I implemented this code: https://bitcointalksearch.org/topic/cgminer-extranoncesubscribe-extension-binaries-available-for-download-850620
You enable the subscribe extranonce function by adding #xnsub to pool url's tail.
In the case of nicehash this is: stratum+tcp://stratum.nicehash.com:3333#xnsub
