Hello guys,

my S9 arrived a few days ago and is working pretty well. Do you recommend to update the firmware? And if yes, how do I do it? How do I figure it out whether the firmware is up to date and which one I need?

My temp at the chip is showing about 70-75, is this a good figure?

The error rate is about 0.0006% (bottom of column DiffA#, right?), is this acceptable?

And at the pool settings: Do you recommend setting three or two different pools or just my first choice pool with different ports? (Pool recommendations are welcome at this point, I'm still trying Slush, ViaBTC and BTC.com)

Sorry for those beginner questions but I just started mining and I want to mine as efficient as possible without driving the S9 too hard to its limit.

I appreciate every help, thanks in advance
