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 

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 960mV and getting around 130GH/s with no - zero - HW errors at 50'000 hashed shares

Many thanks to the helpful users here for their postings.

Michael

(sorry, my english skills are not the best)

Edit2: deleted my recommendation for Technobit because my second order was paid early in April for shipping on 22th. Until today 1st of may: no shipping, no communication, no reply on requests for a status of my order - and finally the item got cheaper two or three times in the meantime. Now trying to get my money back...
