[ANN] Technobit HEX8A1 -240 GHs Coincraft A1 board- Finished production

000: HEX8 0: 260 1000/ 800mV |  0.000/ 0.000h/s | A:0 R:0/0.00% HW:0/0.00% WU:0.0/m

I'd expect to see that if the chips didn't have enough power to fire up. 1000mV should be enough though.
I cannot get mine started under 850mV and they look exactly like that.
If you're sure your PSUs are providing power, maybe the fuse is blown on the circuit board, or you got some really lazy chips?

I don't get where taht 800mV comes from, but will take a visual inspection look on board now...

Yeah I see 840/800mV if the the mV setting is too low <850mV for my Hex8A1.

Wrong first is what you have configured 840 second 800 is just a number. When you got share back from the board it refreshes otherwise it stays to 800 always. What it means that tplink writes jobs orange but no response back
Is the board hot?

It don't matter what number I set under 850mV it will look like..

000: HEX8 0: 260 500/ 800mV |  0.000/ 0.000h/s | A:0 R:0/0.00% HW:0/0.00% WU:0.0/m

I think the 800mV is just some default number it goes to when there is not enough mV to fire the chips up.

EDIT: note that cgminer monitor kill that cgminer instans every cron run..

anyway, why is that voltage 800mV, how I change that? (look few lines above I tried manual cgminer run).

?
Dif-to-one 1?
Is the board getting hot

[Gator-hex]

How long you had it? Are they still shipping them out with thermo fuses on? I thought that was only the pre-production batch?

Can you take a picture closer to the power connectors.

dif to one = 1 <- no use
board is constant 25C degrees (measured IR hand device)

one day today got time to start play w it..

Ok if it isn't working with diff-to-one 1 something else is going on...sorry that is all I can think off....
In general lights are ok USB also thre must be some power issue no power reaching asics for some reason
If you have the skils you ca check the fuses ....

Did you try putting something on the 5v line of your PSU? It worked for mine that had green-orange light (I nicknamed it Bad Boy because it was a problem child! ) https://bitcointalk.org/index.php?topic=376351.msg5178369#msg5178369

[eestimees]

changed the LAN location also, same thing.. so it is not connectivity issue..

also out of ideas... I'll go to bed now, wife already fell in sleep on other room, not wanting to come to the bedroom where I payed with that noisy miner

will continue on the morning..

thanks to all of you for helping!

No only mr 3020
Just to make sure 12v is ok you can measure in on any psu connector using multimeter

no not yet, in 12v line multimeter showed 12.11V will try that 5V fan trick tomorrow, thanks for idea

Can you try:
1. Disconnect all wires from the board
2. Connect Power PCI-e from the PSU
3. power on the PSU
4. connect the USB from the router

If that doesn't work try putting a dummy usb hub in between, you can also power the router from that usb hub since the board provides 5V

Wow, forum is so hot while i am asleep  

Any way last try, how about use powered usb hub to connect HEX8 & TL-MR3020 as 2GOOD suggest 
Or maybe you want to try version 0.2.0

Those ugly yellow/orange things are poly-fuses, check if any of them have come away from the board. The board I have with orange light has two detached. This seems to make the remaining attached ones hotter, which causes them to increase resistance, which probably explains why this board uses 40W more power than my green-green light one. But eventually they are designed to shut off the power if they get hot enough and they might not come back to usable for many hours. This could happen if you over-clocked it too far, or have it working in a hot room, so you might find it mysteriously starts working again in the morning if any of these apply. I've heard people say they stick a dead/overheated miner in the fridge and it comes back alive. Now I understand why! http://en.wikipedia.org/wiki/Resettable_fuse

[eestimees]

back in business 

determined that chips do not get juice (power).. when PSU is off, cgminer displays and acts the same.. something must be wrong on the board..

Try setting 220 for frequency & 880mv for voltage

[eestimees]

I know about electronics as much as sheep about airplanes, but here are some pics:






are those poly-fuses meant to be connected like that?

comparing to that http://postimg.org/image/aphi1ykg5/full/, I have one leg up in the air for all those fuse-pairs...
