S9 hashrate +3.0 th/2s software?

[androyster]

Hello,

I'm fairly new so please don't bash me for this question.  I upgraded all of my S9s to +2.0th/s and they are all running cool.  I see an option for +3 in BTCtool.  Is there a
flash upgrade for the S9's to take them to +3 th/s?

Thanks,
Andy

This should be in the mining support board instead.

Short answer: NO

Long answer: This is probably a glitch in btcTool, the multi-option firmware has an option to underclock the miner by 3 terahash but a maximum of 2 terahash for the overclock, you should NOT attempt a firmware upgrade, the latest version has no tuning options and you probably can't revert to the 2019 firmware which has the drop-down options for tuning, I also believe +2th is already good enough to sustain your miners anyway, don't push them hard.

Thank you for the reply.  They are running pretty good on the +2 right now.  Just saw that.  Thank you for taking the time to reply.
