Ultra Under-overclock image for A2 Innosilicon by Emdje - V5.0

[coinsy.org]

1300 Mhz is your limit for the Black A2 units because of hardware limiters and smaller heatsinks. The silver A2 units do not have the hardware restrictions in place and achieves a constant 96 MH/s at the pool at 1320 or 93 MH/s at 1300. If you take the Silver units any further than 1320 you'll be doing 80 MH/s at the pool because of the invalid nonces's. These units are dumbed down from 150 MH/s so innosilicon wouldn't have to go back to the drawing board for the 110 MH/s units they are now shipping.

If enough owners complained we could get the source code and get at least 110 MH/s pool side with no hardware modifications or close to 150 MH/s with hardware voltage modifications.

Guys, just a noob question. Im not able to shutdown miner via SSH. Either 'sudo shutdown' or 'sudo poweroff' kills just the OS (disconnects SSH), but the miner keeps running. Any idea? Thanks.

There is no way to power off the miner remotely because it's "jumped" at the control board.

Of course you can soft power off the device, just ssh as root and type "shutdown -h now", if you log in as user pi "sudo shutdown -h now" should do the trick.
This worked for me a thousand times on any of my linux machines.

does anybody know if this will work with the new A2terminator mini, and with what frequency setting, if so?

I have not seen one yet on the inside but I bet it will work on the 'new' a2 miners. Just a new form factor and reduced price I think.

Excuseme guys, so when the ip from miner not connect It is because the IP is dynamic? i tryed to follow this manual but not work. i got the 88+ MH/s - The A2 by Innosilicon - ASIC Scrypt Miner

Code:

http://fuk.io/a2-terminator-innosilicon-scrypt-asic-miner-setup-guide-and-review/

so is good idea call to my isp to change to static ip?

I'd like to try this image on my new A2 Mini I picked up at Zoomhash but can't figure out how to power the damn thing to get it mining!  The 2 "PCI-e" connectors seem to take 8 pin connectors but they are Keyed wrong and 8 pin pci-e won't fit and miner won't mine or start fans with 6 pins plugged in.  Only thing that seems to power up miner is if I use 2 of the 8 pin CPU power connectors from my PSU but with thagt only 1 side starts mining at ~18MH/s but cuts out and stops mining after 1-3 minutes (miner still running but not hashing).

If anyone has some info to help I would be Grateful!  Nice work on getting Overclock Image working btw Emdje and I'd try it out on the new A2's once I can get mine working at all

[chapinmaster]

Its working now with this imagen
http://fuk.io/a2-terminator-innosilicon-scrypt-asic-miner-setup-guide-and-review/
but onlu run at 68.91 Mh/s on ghash.io
it´s time to mine some dogecoins, thanks guys...

i agree, i wasn't 100% sure how to plug it, but i figured it out.   use 6 of the 8, and the 6 towards the middle.    the last 2 are purposely 'keyed wrong' so that you can't plug in the +2 I assume.

also plug in the big ATX power into the board that is far from your PCIE plugs.   that willl get you on and into raspberry pi.   then..... thus far no working image, which is what I'm looking for.  msg me if u get that!

[chapinmaster]

hey guys any idea why never run at 80 mhs or more, im runing at 1360 mhz all the boards and only get
(5s):84.37M (avg):83.63Mh/s (pool):53.05Mh/s | A:245760 R:0 HW:26 WU:48572.8/m

but really in the pool just get 47 mhs maximum, i try 4 different pools and same...

Hi Emdje,

I know this is a really newb question. But what ip address is the new firmware set at? Only asking because my mates placed our internet connection on 192.168.2.... rather than the usual 192.168.1 and am having trouble working out what ip the firmware web interface is set at?

Ive tried 1.125, 1.136, 1.106, 1.163 and im out of guesses now. lol

Any help would be greatly appreciated. Cheers mate

The OS is set to DHCP. I advise using a port-scanner to find out.

[alpatcomm]

Ahh, cheers mate. Like nmap for example I guess. Well I Jst answered my own question. Thanks BakSAj

[alpatcomm]

Hi guys, Ive setup the new firmware and it seems to be running smooth at 1320mhz, which most people agree on this thread, is a good stable point for each module.

Only question i have is, whats the best setting to place the DEVICE INITIAL DIFF?

Ive set mine at 128 for the moment, but I'd appreciate any feedback/explanation which anyone may have.
For example, what setting is most suitable and what exactly is the 'DEVICE INITIAL DIFF', in the first place?

cheers again guys, appreciate all the help so far.

Thnx for the answer BakSAj. I logged into the router and looked at the connected devices to figure out which ip-address the miner had.

Depends on the mined coin. A very 'fast coin' (fast block time) requires a lower difficulty, a 'slow coin' (slow block time) requires a higher difficulty. A lot of pools have automatic difficulty selection. When that is the case you don't really have to do anything.

Thanks mate. I get ya. Example wafflepool suggests making ur password based on ur hashing power. Being mine is between 64mhs and 128mhs, they suggest setting password to d=32768.  Is that the sort of thing your referring to also? Or am I goin off topic now?

You are going a little bit off topic   but yes that is possible too.

[alpatcomm]

I thought so. What I'm talking about is more in reference to the WU, not the physical miner, which is what this thread and your OS is all about. Apologies to yourself & everyone BTW for simply adding rubbish, to a really good thread

It's alright. I actually added quite some rubbish myself in the beginning of this thread by posting an image that did not work 

[alpatcomm]

Haha! Gold! Fair enough then mate. Still though, you've done pretty well since then. In fact awesome progress. Ur current release is sweet as and runs like a dream

On request from BakSAj I am trying  (not yet working) to compile a version under cgminer 4.6.0
