s7 is old gear and pretty much worth very little , unless  your power cost is free or very low cost.
So before I give any advice to you I ask you how much does your power cost?

Phil is correct  you need very low power cost for the s-7 to be worth while.

As for setting the frequency   higher then 700  sometimes you get melted gear.

so  let me show you the s-7 in an earnings calculator.

at 10 cent power it is a loser no matter how fast you run it  freq 650 ,700, 750  all lose

at 5 cent power it may or may not make money

at 3 cent power you look like you will make money  but racing it could burn it

okay you have cheap power .  so your gear should be able to make more money then it cost to pay for the power for 18 months maybe even 24 months.

So pace your self and do not race it and burn it up.

so rather then  700 freq  do 675 freq   set fans at manual speed of 70% and let us know how the gear runs.

a screen shot of the gear running.

this is with the important info in red.

You really need to decide the nice thing about antpool and F2 is PPS.  So you bring in a steady income but pay a fee.  There are pools like Kano.is that use a system where luck is involved in it's case PPLNS ( https://kano.is/index.php?k=payout ).   Kano I would say has the most loyal users.      But again you need to decide what you want to mine at.

Are you saying you one week for the 3 costs 112 dollars?   I am not following what you said with amount.
