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

[zulover]

Any setup guides for this, if someone cd post link most helpful.

260/1005 = 33   A  ~ 396 watt
265/1030 = 37   A
265/1040 = 38,5 A
265/1050 = 39   A
270/1050 = 40,5 A

You better use your corsair to powered HEX8  

How stable was it on 270 and 1050? Did you test it higher? How good did that work?

Not recommended at all to set it higher than 270 Marto is free to correct me of course.
Any way i have tried it up to 268 and all was good

Agree, that's was for reference only 
5 A for additional 5GH really not worth it

If you use the TPLINK (wich is the best solution) you can use this : https://bitcointalk.org/index.php?topic=476326.0
If not, simply read the old posts of this topic, you'll find information onto how to patch cgminer and recompile it.

It should be on the way by now right? Did they lost it already? Anyone else see the same?

cool
they have some lag in data representing

Confirmed, as far as I'm concerned their tracking page was updated yesterday night and I receive the package today...

I have received my devices, will plug them in after I get home from work.

EDIT:
I have connected them (used a brand new Corsair CX750 PSU for the two HEX8A1 miners) and they all work. I have replaced the 4 port hub with a 7 port hub (this one even has diodes so that the HEXB miners do not backfeed the power to the PC). However, one of the HEX8A1  has 5% HW errors:

1. Is there a way to reduce the overclock on that particular device, while keeping it on the other two?
2. Do these devices report their temperature? If so, how can I see it?

But yea, the heatsink arrangement makes it difficult to place the miners so they do not blow hot air into one another or other miners...

Hy again!:)
The five hex8 now work nice with 52% CPU use. But when i connect one hexC or hexB then the CPU spin up to 100% and the performance decreases on all board. While this the hex8 board red light pulses.
Now i have two RPI. One for 2xHexB 1xHexC and for the other 5xHex7.
Any idea?
Thanks!

I have RPI A, and when i use 5 Hex8 miner, then the cgminer process goes up to 100% cpu use and therefore decreases the performance. With 4 work it 70% and all is nice.
Is there any solution to config less work to the cgminer?
Thanks!

Sure --set-dif-to-one 0
Check my spelling though it is written in chnagelog. And make sure you are using latest version -you will know it when you see pool reject rate % in screen session

Get a TP-Link TL-3020 it kicks the ass of the RPi.

Red light of hex 8 means it has no work. USB writes are taking too long for some reason. It seems some USB issue. Try with other hub or use the one I have recommended ....
And finally tplink if all fails
However if all is good at two pi's follow golden rule if it works do not touch it

Well that was not the case in my case. Now I see it still in SOFIA in DPD HUB... Got DPD number. So at that speed I'm not sure when I will get it...

03/07/2014 18:44    DPD data centre   Additional information    Shipment data transmitted

It would be the same if we would use UPS today... Probably batter since it would be deliverd same day it get to Slovenia not next day as it is in case of DPD. Where did they get Speedy name...

Did you change "Handle USB detect errors as (Default: hexA)" to Hex8?

Is your Hex8A1 plugged directly into the TP-Link TL-3020 or through a USB hub?

Try plugging it in directly and see if it works. USB might be leaking power and power protection hub will stop it communicating.
