I'm sorry to hijack this tread, but can someone share lowest possible settings for S9 with Brains? One of my miner is able to run 500MHz@7.9 (10.5TH) with 880W consumption at ~240V. Others do 500MHz@8-8.2V with 930W+.  I guess you can go lower with frequency, but as far as I know 7.9 is lowest possible voltage for S9.

you could get  all 7.9  which is best

then play with MHZ

you may find a

7.9 > 475
7.9 > 475
7.9 > 475  gives you the best watts efficiency

I have no access to the braiins I set up until tues.
and my 815-823 watts numbers were gotten using a corsair 1500 watt titanium psu
I know that would be okay for a small miner if he got a good deal on the corsair

IIRC  I did 815 watts and 10050gh  and fans were close to  2500 rpm

In the current location  it is doing

   s9brains   9.089T   9.549T   9.690T   0.10%   2019-03-03 04:25

9.69th at the pool

the dips are reflections of power on and up during setups of other miners and fans etc.
