We need a comprehensive report of the states in which people's boards are going bad. There are a ton of reports of bad boards, but little useable information.

I think that it would be helpful to Barntech's team if we could list how boards were hooked up, i.e. miniplane or not, pci-e power or not, etc. I would also think that powersupply type, with as many details as possible would be helpful. Reports of failed boards don't tell anyone much, other than failure rates.

550 watt psu,no backplane used,used 2-4pin molex lines-2 per line(each molex cable had 3 connectors,used 2).

No other devices on PSU except mobo/cpu(45 watt dual core)/hdd/dvd rom & NVidia 8100 non powered vid card(no external connectors).

No OC'in was done,ran @ stock CGminer settings,got CGminer from drillbit forum:

No green light is the problem on 2 boards.

I miss anything  Huh


I would pull everything off the PSU except the MB and 1 Eight. Use a working one so you know the PSU and cable is good... then turn everything off and replace the good one with one having problems.. If no green light then you know for sure its the Eight having a problem.
