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

[Gator-hex]

I am still not sure what settings should I use, because the outside of the heatsink is still getting pretty hot und almost untouchable

The rule I use is can I keep my hand on it for 10 seconds. Are you still running them 260/1000?

Well, depends on how much pressure do I use to keep my hand on it for more than 10 seconds
No, never actually tried this settings, currently running @ 230 and 950mV

At 230 you can go down to 900mV or less, check out my settings here:

Keep in mind that some settings may not work well on every board, you have to find your own sweet spot

A fast question, there is any solution for that the hex16a2 mini USB power dont give backward 5volt ? When i cut the usb cable red and black cables, then the board dont work.
Thanks.

Wierd, when I taped out the outer pins on my troublesome Hex16B board's cable, it worked fine.
(also work on Hex8A1, but it was something else that was the problem, needed a fan on the 5v PSU line, to help regulate the PSU.)
Are you sure you didn't damage the data cables? If you are, try adding back the ground. If that don't work you could try +5v and ground powered from a 5v PSU line (Red/Black), with more Amps in the PSU it shouldn't flow back, and PSU is designed to handle bad loads if it did.

Hy!
I dont have 5 volt on the PSU. At the first moment was worked. And then when i restarted the PSU the board Led don't Light up and the Rpi dont see the board. When i plug the red/black back then works fine. The fan worked fine on all two try.

Raspberry Pi is crap has a history of USB/Power issues. If you use a TP-Link TL-3020 as your mining PC it won't care if the USB leaks power or not. That's another way I found to handle a leaking miner, stick it directly on it's own TP-Link TL-3020.

+1
Or if you are paranoid just strip USB cable gently and cut red wire + 5v and leave the ground

Hello Martin,

I thought we agreed, order: RTCNXJFCR had not yet arrived and the deal was the end of February. If did not come until now, I doubt that will ever come (maybe I'm wrong)!
Could you please be so kind and answer me, or are you again violated our agreement. I slowly losing my patience and if my order, what we agreed 3x 260GHs HEX8A1 new and full tested, not come until Friday I will be forced to act by as I told you!
Once again, the deadline is Friday. After that I go to the Police!

[marto74]

Dear,
You can go to police at any time, just tell me not to ship before that.
All our orders are end of February shipment and today is 26 of FEB.

Do you think I like doing this, I apologize for the inconvenience if I'm wrong?

"End of February delivery" means they send out the miner by the end of February, not that you will receive it then. Just like the pre-production batch was Feb 10 delivery so they shipped them Feb 10 - 13 (my unit was sent out on 12th) and then it took some time to arrive. I expect the end of February units to be sent out before March 3rd (I have two units ordered in that batch).

You cannot expect a definite delivery date because various shipping options take varying amount of time.

Mine has been shipped on 17th.
My previous order has never been sent (but i have been refunded for that).

Hi,
I understand everything, but I paid 3 months ago, I no longer have patience!

How is that possible 

Tecnobit start selling 30 Unit pre-production HEX8 on January 21, 2014.

you dont need to go to police just ask your money back if they dont sent you product in the end of the month. If they refuse that then you can go to police. Is a EU company and i dont think they can avoid for long time to refund you.

Final setting, 260/1005.
Already run for 3 days with stable hashing rate
