Hash them flat out till the power cost becomes more than the BTc value you can mine.
So I have my block erupter cube cooking along nicely.
All the chips are running perfect.
I have it currently running at the default low speed. Will it be more reliable in the long run or should I crank it up to high?
It's inside my office at work so the temperature is roughly 72 degrees in a fairly dust and dirt free environment. It currently has the one standard fan that came with the cube running.
Side note, I put it in to high speed mode and within 5 minutes it fried my cheapo power supply. So, now I have new Corsair model that should be able to handle it easily. But, my question above still applies.
