Title: Down-clocking S7's to 500Mhz? Post by: wmabern on July 10, 2016, 05:45:28 PM I apologize if this is a dumb question, but I'm pretty electrically-challenged.
If I were to down-clock all of my S7's to, say, 500Mhz, would it save any measurable amount on electricity over the days/month? Or does the PSU still pull a set amount from the wall vs. pulling the amount needed to run the miner? Thanks for any replies! :) Title: Re: Down-clocking S7's to 500Mhz?

Mine could do .249 watts a gh with a platinum psu. So if I ran it at 4000gh it used .249 x 4000 = 996 watts at the wall if I ran it at 5200gh it used .249 x 5200 = 1294.8 watts at the wall so on the yes the watts are lower and on the no the watts per gh are the same your plus side for lower freq/gh are it runs cooler you can lower fans manually to 40% which means some peace and quiet and of course less watts at the wall. the down side is less gh.

That makes sense. I'm trying to decide if it is better to only run my S9 24/7 and run the S7's after it cools down and I can run at full speed. I'm currently running my single S9 and will power up the S7's tonight. I need to lower my electrical costs. I figure only running the S7's for half a day will help my electric bill. I know it will make for an unstable 5ND on Kano, but I need to do something until the BTC price rises again. If the price on the S9 drops significantly, I will get another and just run those. At current BTC price, I will still make a tidy profit with two S9's. Thanks for your input. :) |
