cool I will try it.
I don't think the new firmware allows it.
The sept firmware lets you do it.
the nov does not.
and after some trial and error both nov and sept firmware are doing lpm.
man the nov firmware is really bizarre.
it reads -4121 gh hashrate
the pool reads 908 gh
the kernel log is weird
it claims. the mining failed at 23:55

So over night I ran the modded s9k. ..... via inspect page options
and I don't know what the f is happening . I am using team viewer so I can not measure the power drop.
yeah hash dropped from 13 to 2 but. it is easy to see really low fans and really low temps
![](https://ip.bitcointalk.org/?u=https%3A%2F%2Fi.imgur.com%2F3Nha3oC.png&t=665&c=0BmTtO2XAnybcg)
here is one not touched higher hash rate but way higher fans and temp.
I wonder just how much I lowered power.
A lot for sure but I need to drive up to Clifton to measure the power drop. if power has dropped to 200 watts vs 1300 these are very nice solo mining gear.
