Technobit HEX8A1 130GH/s Coincraft A1 based miner reviewed

[loshia]

Hello together

First of all, I would like to thank Technobit and Martin for shipping my Hex8A1 130 promptly as promised on their website (JBAWWKAVT).
I had no difficulties to install and run the Hex8A1 on a Windows 7 system with cgminer 4.0 (already running a few Bitburner Fury on separate instances of cgminer - yes, I'm a little noob thats why I use a Windows system ).

Still testing with a Corsair CX600 as dedicated PSU and some settings in cgminer. Actually using 4:263 at 1000mV and the hashrate is about 126 GH/s with +/- 6% HW errors after >100'000 shares.

edit: meanwhile testing with 8:250 at 950mV and getting around 130GH/s with no - zero - HW errors at 50'000 hashed shares

Remembering the negative statements about Technobit in other postings I have to say that my personal experience was good. This was my first order at Technobit, everything worked fine and I also got answers on my questions.
I've just ordered a HEX8A1 260 GH/s miner in the hope everything is working fine again  

Best regards - and also many thanks to the helpful users here like Zich and the others for their postings.

Congrats dude
If you feel brave you need more juice above 260 something like 1050. This will reduce hw errors but the chance for magic smoke to come out of the bottle is increasing
But as said this is for brave soles only

Hi,

Thanks for the hint! Not sure if I'm brave enough to go to 1050 Don't want to overheat the miner.
Atm it's running well with 250 and 950mV, hashrate dropped a little bit to 128GH/s, HW errors are only about 0.18% - at least for me these values seems to be fine

1. Read zich tutorials
2. Use tplink if you can not handle it
Good luck dude

There must be some missing of comma or apostrope on your conf.

I did't see anything wrong with the conf. So you need to delete existing conf file & ask cgminer to generate new conf file.

Okay i will try that zich...

then i started up cgminer ....
(now there is 2 cgminer.conf files one with "pool" on the image and one with "..." and i can not delete any of them)

add sudo on your command

[shortpocket]

sudo ./cgminer?

i did that.

[Zich]

sudo ./cgminer?

i did that.

i mean add sudo when deleting conf file. You don't need to delete cgminer folder since conf located in other location.

[shortpocket]

i tried to delete it by right-clicking and move to trash since i dont know that many commands

Did you patched and recompiled cgminer?

[HellDiverUK]

API filing to bind makes me think there's another instance of cgminer already running that's got hold of the USB miners.

[shortpocket]

Have been patched.
No other instance is running.
