what program you using? bfg or cgminer? i noticed a lot of errors 1-3% with cgminer on windows and occasional crashes. i started using cgminer for linux and it runs smooth. minimal errors if any .1% or so. also never crashes running solid for weeks.
I using multiminer with BFG on windows 7 machine.
My errors can be 10-20% most times. it is interesting about linux though, I have Ubuntu install on same machine as 2nd OS in duel boot.
I'm heading back away to work for 2 weeks but I will update the ubuntu and test it on my my next break. (Everything seems to break as soon as I'm away at work)
Thanks for the info.
Cheers.
