Well if you are out of jobs you could start tweaking GAWMiners source when they release it (was supposed to happen today or so)  ;D

Anyone have any tips on how to control the clock speeds? Firmware 2014-05-21 includes 1000MHz, 1200MHz, and 1280MHz. I'd like to try higher.

Is anyone else having difficulties with one or two blades going dead when switching pools?

sudo ./cgminer -o stratum+tcp://pool:3333 -u worker.1 -p x --A1Pll1 1200 --A1Pll2 1200 --A1Pll3 1200 --A1Pll4 1200 --A1Pll5 1200 --A1Pll6 1200 --diff 8 --cs 8 --stmcu 0 --hwreset --no-submit-stale

Any chance you could split this thread into two? The altcoin mining support stuff really doesn't belong here.

A2 Terminator

Mining Capability(Official Number):
Scrypt: 75 - 89 MH

Power Consumption:
Scrypt: 750 W/Unit
[/center]

So rumor is there is a 140MH unit in the works    ;D

The products of Innosilicon A1 and A2 consists of modules with each 8 chips on it.

the 140MH miner would just have 6 (84mh) + 4 (56mh) modules ...

Is 1280Mhz official supported or does using it void warranty?

MinerEU https://github.com/MinerEU/scripta_a2
A2 controller update:

3, frequency setting for each blade(over clock tuning )

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

A2 controller update:

Just so everyone knows, added new feature in this update

1, switch pools on the fly without restart
2, pool priority setting
3, frequency setting for each blade(over clock tuning )
4, temperature sensor display
5, core info on each chip

Are you sure, you have uploaded the right version? I installed posted version but I don't have these functions. Seems like it is a previous version.

Lol why static ip?? DHCP exist from long time....

U always can see the miner ip into your router.. So my network is setting up with ip's start with 10.10.x.x and can u tell me how this firmware will connect with my network please?

Ps: ok let's say I can donate if I see DHCP version of this FW...

on my router I have 50 devices connected with static IPs I have to stop all of them to able make this simple procedure... no thanks :)

Hui,
hast Du ihn irgendwie modifiziert (abgesehen von der Software)?

http://i057.radikal.ru/1406/88/2bc4cfc5d4f9.jpg BINGO !!!!!!!
 
 

Felix which version did you use for this? Could you paste a link please?

Does anyone have an issue where the miner turns off for no apparent reason?

It happened 2 times in 2 days, before that it was running for a bunch of days no problem.

The OS was just updated to the new changeable 3 clock speeds recently as well.

It was also noted that it would drop down to 64Mh/s or so, meaning one or two blades went out for no apparent reason, when restarting it by powering off then on, it comes bak up to full speed at 90MH/s

Is there an automatic temp cutoff somewhre? or what is the max temp it can run at?

Any ideas?

thanks!

I would also like a link thanks  :)

anyone else have non working graphs on the innosilicon gui image?

Hello,
I would like to integrate Innosilicon support to Minera (http://getminera.com), can you tell me where is the source version of CGMiner that supports it?
I won't use binary version from other system like scripta, I would like to be able to compile the correct one for Minera.
Many thanks.

Looking forward to this ;)

Anyone else getting a crc error when extracting "InnoSilicon Customized WebGUI RPI Image for A2 Miners (2014-06-18)"?

Does anyone here happen to know the username and password to log into these Innosilcion A2's that were purchased through GAWminers? They've been absolutely horrible in providing support. We can't login through ssh nor is there a web GUI running as well. We are dead in the water for over a week now... We've submitted a ticket to them and we haven't received a response yet...

Can we or should we just flash over the SD Card with a known good image with a known Username and Password from another reseller like MinerEU? So far, we haven't found a great deal of support out there on the internet about this product.

FYI.. It looks like Minera is supported now by the Innosilicon A2 mining equipment now...

Can anyone confirm this?  I do not see it stated anywhere else that Minera supports the a2.

My a2 is currently under a rental contract,  once that ends in a couple of hours I will check and report back here later this evening.

I have minera installed on an sd card but can not figure out the ip or a way to log into the machine once installed.

Download Angry IP Scanner. That can help.you.  After you find the IP,  You can SSH into it with the username pi and password minera. Then after logging in type sudo su to get root access.

Also can open up connected devices to your router.  it will show connected devices no need to scan that way.

    I will say that the machines actually pull way more from the wall than advertised.  That being said, they are currently the most efficient.  That also being said, you can get 44Mh/s for $799 @1kwh now, so I think your prices probably need some tweaking to sell here (since this audience is more informed).


No it doesn't pull "way more" from the wall than advertised and it runs 102-112 MH/s at the pool with the cgminer update.

It will soon do 150 MH/s at less than 1K watts per Innosilicon.

Quote

    Its per chip performance has reached over 1.6MHs to 1.8MHs at only 10W power consumption, which can allow for the unbeatable up to 150MHs per box performance within only 1KW power supply & very quiet fan cooling.


The device was designed to be able to tweak to twice the nominal speeds. Go read it on their website and get "informed".  8)

Glad to see you found the problem. I have a question. I made an image that allows for more over-clocking options. However, in the code, the number of A2 chips is hard-coded. How many chips, with how many cores on each chip, does the new A2Mini have. I might be able to convert this version to fit the new A2Mini (I can't test is myself though).

Thnx

thanks for the info.
It probably says 12 chips because it is an adapted version form the A1, which has 12 chips.
I you click on the 'stats' page you should see the temperature per chip. Could you post a photo from that? (I need the number of cores per chip and the amount of chips)
And at what frequency are you running it?
When you have indeed 10 chips per board you should be able to go to 40MH/s

Chip Specs
• Developed on 28nm using very low power design techniques and best efficiency.
• Custom IC package with power bars for low voltage, high current feeding.
• Configurable in daisy chain mode for distributed work with up to 253 ASICs.
• Standard SPI interface with CS pin needed to enclose all useful SDI and SDO data.
• 27 highly optimized hashing engines based on custom ASIC cells up to 1.6M.
• Built-in redundancy architecture to allow for bad engines to be bypassed without affecting mining operation.
• Flexibility to configure the PLL clock and computation performance.
• Hashing power of 1.6M in nominal and 1.8M in Turbo mode.
• Power usage of 10W in typical nominal and 12W in typical Turbo mode.
• Supply voltage of 0.78V in low power, 0.84 V in Turbo mode for ICs.
• No need for special cooling, just regular top and bottom heat sinks plus fan cooling.

The Device Specs
• A Total of 2 boards with 10 chip on each board, Total 16 Chips in a miner
• Turbo Mode Hash rate 1.8Mhs*20 Chips = 35Mhs +/- 8%
• Power = 350Watts normal
• Size = 51cm—42cm—16cm
• Temperature = Runs cooler than the A1 miners

The screenshot you posted states 12 asic chips per board.
The device specs you copied from Zoomhash are weird: "A Total of 2 boards with 10 chip on each board, Total 16 Chips in a miner" (2 times 10 is 20 and not 16 :S )

I will change the maximum number of asic chips accepted and I will post the image.
One question: Is the turbo mode a hardware or software option?

One chip appears to be melted, maybe i can try to remove it ?
someone had the same problem ?

hi eraser
I have same problem with chip UA4
https://bitcointalk.org/index.php?topic=626327.msg8958039#msg8958039

I remove it, cgminer detect blade with other seven chip, but doesn't start mine :(

try to connect left side of a2 chip with right side of a2 chip.

Cs_L and Cs_R and so on with the same id.

http://www.usbminers.nl/Innosilicon_A2_PG_v120140424.pdf

I've red the datasheet and left side is the master side and right side the slave side, maybe to short the two can give at the other chip the path to process hash.

Attention to do not short VDD with GND or the signal with Vdd or Gnd.

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

Hey guys.
need your advice.
I bought used 90 Mh/s a2 miner on ebay
HW errors i get are rather high 10% + at 1200mhz.
with 1280 i get over 15%
Is that normal?
Avg temp is 39-40. Solo temp max is 52-53

prohashing 12% errors
multipools would have more hardware errors?
even litecoin pools i get 10% errors
if I lower from 90 to 50-30mhs then i get little errors.
Maybye PSU?

Anyone can advice in replacing psu? Maybye my is causing errors.

Howdy!

I have 2  A2 Mega's with 6 blades. It appears as the PSU died. So I replaced it with a 1300w. However the machine still won't power on with ANY blade connected to the PSU.

The Pi and Controller board have LEDs and I can login to the Pi. However as soon as I power down, then plug in a blade to the PSU, nothing powers up.

Any ideas or suggestions.

In my case it appears it was a crap PSU. I have that A2 working right now, running 1200, but I am only getting 88mhs out of it. It's running great, I was going to work on changing the other settings this week. BTW I had to plug in the power to the blades backwards in order for it to work.

On my other one, it works and runs for a little bit but then powers off. During the time working, it starts out at 88mhs then slowly dwindles down to 6mhs then it powers off. I am assuming I have bad blades or something.

My problem was indeed that the Raspberry Pi controller that was integrated into my A2 Mini Terminator was defective.

Replacing it solved everything.

I purchased an A2 Terminator and it arrived but won't boot. I've re-flashed the SD card and tried another card that's working in another A2 with no luck. It seems to be a problem with the Raspberry Pi, I get a power light but no activity light. It seems to be an old Pi in the A2 (as it has an SD slot and not micro SD).

Can I replace it with a newer Pi?

As anyone done this successfully?

Is there anything else I should try before I buy a new Pi?
