Weird but seems to have gone away after reflash. I contacted bfl as now my fan is noisy and temp up by 2 degrees (still within normal range) so they are sending me a new fan and some thermal paste to refit the sink. Dont think the two issues are related but odd none the less.
Did you contact bfl about it and if so what was their response?
Can't remember - probably not.
However, I contacted them when I first got the BFL coz it took 8 hours to 'burn in' but after that was OK until the problem much later.
The first day problems were most likely the heat sink since it rattled when I first got it - and running hot for 8 hours probably helped reseat it properly
The later problem went something like this:
damn it having problems, spent a week (or 2 or ?) messing with the cgminer code sometimes mining full speeds, sometimes half speed (power cycles sometimes helped) then finally decided, stuff this I'll put in a fast bitstream and see how long it takes to kill it
880 didn't kill it
I'm still using the 880.
I also found that with the 880 bitstream it worked at a much higher reported temperature without throttling.
At the moment it says 61.5C (when I first got the BFL it throttled around 50C with the 832 bitstream)
Last time it throttled/had a comm error was ... 8-Nov ... had 8 that day coz it was very hot here (it's now summer)
Previous was 16-Oct - 3 times - was a hot early evening and that's the time it throttled also.
