Hello,

I have a problem with a A2 Terminator that I can't seem to figure out. I scanned all 26 pages here and it doesn't seem that anyone else has had anything close.

When the unit powers up it appears to hash normally according to the software stats. However, after about 30 seconds the rate starts to drop (each board) and after about 2 minutes all end up at zero.

I have tested most of the hardware/software and can rule out the following:

PSU - New, replacement is a 1300 Gold
Pi - Tested in another machine and works fine
Cables/Cat5e connection - All work fine
Software - Original software that worked before this problem started. Also works in other machines

Can anyone point me in a possible direction?  I am at a loss.

Thanks,
Anthony

Anthony,
Symptoms say power. Disconnect half the boards from the power supply, and try again.
My slightly overvolted and overclocked (1320MHz) 110 A2 Mega draws 1400ish from the wall, with 3 blades per power supply (gold).

https://1drv.ms/i/s!AtWS9QC1pUm4iJFkq5v75zNg9PiwGg

in the image I have attached you see my A2 4.0 version of your firmware, but that marks it as cgminer 3.9.0 instead of 4.9.1 ... and see how I created some hardware failures ... is this normal? and a 30 mh set in pool 1024 and as board speed to 1200mhz

thank you

The A2 image was never made to use WiFi out of the box, I think you still need to install some packages to get that going, but I am not sure anymore it is a long time ago since I got the WiFi to work on mine.

 Fans working correctly?
 It sounds like you might have an airflow issue and are overheating.

Good day

I have LKETC A2 Miner with 4 board (60Mh). My SD card is broken, and i do not have copy of it (my mistake). Trying to install your firmware - web working, i can change settings, but miner not start mining. Do your firmware is suitable for my miner? If so - where can i change number of boards?

Found some log's

Minig working fine but after some work time web interface become unaccesible. And no temperature information on real time monitor page (Emdje - Under and Ultra-Overclock version 5.0).
