I'm tired of testing now.
18 days of testing to get the unit hashing faster, but no success here.
What I tested:
1 netbook 1666MHz Intel Atom 1GB ram Win7 32
1 notebook 1800MHz AMD something 2 GB ram Win7 32
1 notebook workstation Intel I7 2720 8GB ram Win7 x64
Checked energie options for USB Ports etc.
Tested with powered USB Hub (Logilink 10 Port) and without.
cgminer 2.4.3 (115200 baud)
cgminer ep version (57600 baud)
mpbm (115200 and 57600 baud)
shipping = 60Mh/s/week (120Mh/s/hour max)
twin_test = 60Mh/s/day (386Mh/s/hour max)
190M_V4 = same as twin_test
190M_V3 = 120Mh/s/day (401Mh/s/hour max)
200beta = 5Mh/s/day (280Mh/s/hour max)
Every bitstream is hashing 1 minute and up to 14 hours at nice rates, but after this I get many invalids (>80%) and the unit will stop working correctly, 0Mh for about 3 hours then again some shares and so on.
I'm really upset at the moment, I invested ~6 hours a day 18 days long to test things, I thougth I was doing something wrong and tested every switch settings I know. The answere from enterpoint that there is a frequency/noise problem did't help me futher. And they said that they "think" to work around the problem with their bitstream scares me too. Hardware problem?
Today I did my last test and after that, the cairnsmore1 has learned to fly from one corner to the other in my room, god thanks it landed on the couch but jumped again up and fall down and dropped in the package in which it was delivered... I think it will go back to home ..."E.T(P). phoning home"... (someone knows that?)
So this baby is now waiting in the package... I don't know what I should do now.
@yohan: any news or piece of software we can play with?
And a 60W switching psu with phoenix connector
