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

[LordTheron]

Apparently minereu has firmware that works with it:

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.

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!

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).

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.

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.

Allready tried some  , but unfortunately it doesn't take yet, it switches to 1000 MHz

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.

[emdje]

The miner accepts the lower clock values, but somehow whatever options I add I end up with half mining speed on the pool.



Anyone any idea?

A2 board after I took the heat sink off. You can see the four voltage regulator circuits (two in the middle of the board on the sides, and two almost on the top of the board)


Dahmn those SMD risistors are small   
I could not find SMD resistors of the right size or quantity below 100, so I took some high precision 'normal' ones of 12.7k (measured all around 12.36k) and soldered four on one of my two boards.

Will post screen-shot to show improvement in hardware errors. Seems like there is a lot of improvement

[emdje]

Board 0, is the original one, with HW error % of: (40*100)/(369+40)=9.78%
Board 1, is the tweaked one, with HW error % of: (1*100)/(408+1)=0.24%

Update: It is now 1.5 hours later and board 1 still has only 1 HW error, board 0 now has 75.
Update 2: 8 hours later, board 1: 6 HW errors, board 0: 208 HW errors

Pretty good difference  


Temperature difference is significant though.

[quakefiend420]

So you're overvolting?  How much?  What's the difference in power consumption?  Any more frequency headroom?

[Prelude]

Awesome! More details! 

[emdje]

Yes I am overvolting.
The original resistor (05c value ~ 11k) was about .84 volt. I soldered 12.7 k (measured 12.4k), which is about .90 to .92 Volt.
I have not measured the power consumption yet.

Yes it allows me to set the chip to a higher frequency. Board 1 is hashing stable at a frequency of 1320 MHz, and after 10.5 hours shows only 10 HW errors. Board 0, which is at 1300 MHz shows 284 HW errors.
I will try higher settings later
And when I measured power consumption I'll post the reading.

Interested to see what happens here...nice work!

Put the overvolted board on 1400 MHz. Has been running for over 22 hours and produced only 34 HW errors.
The other board at 1300 MHz produced 591 HW errors, and if I put that board on 1400 I effectively cripple it.

Hi, looking at stat page I have a chip with a higher temperature, all the chips are at about 40° but one is at 62°, How can i solve the problem?

Thanks W_M

Wow, that's great! Might have to do the same mod, I have 1 88MH unit and 1 60MH unit. Good job!

How fast is the blade hashing at 1400mhz?
