I've got two that have been modded. They run for about a week then I lose a board. I turn it off and then on and it comes back for about a week. If you're hosting them at home and keep an eye on them, then it's not much of a problem. This happens only to the modded ones though.
That is not exactly true. Both of my units are unmodded and they only last between 7 and 14 days before requiring a restart due to a board dropout.
try my script in the last page of the modding thread..
https://bitcointalk.org/index.php?topic=1504228.msg16518866#msg16518866just change 290000 to 190000 or so.
oh also if yours isnt modded change the starting pwm to whatever you have your fans set to.. 60 or 70 should be ok. also make sure the customize fan speed box is checked for it to adjust the fans to keep the temp between 60-65.
Well, that could work.
