Title: Antminer S7 Underclock?
Post by: left-ca on December 01, 2015, 12:32:08 AM
Is there a way to lower the antminer s7 to under-clock it to around 4th/s. I dont really care about efficiency but its just so loud and i would prefer it a bit quieter. Thanks

yes

I will post how for you.

Set. Freq to 500

Set fans to 30%

Check your numbers after five ten minutes.

You should be close to 4000gh close to fan speed of 2800rpm

Temps should be under 60c for safety

Antminer S7 Batch 8   at Frequency 600 is 4,047 MH/s

But I suggest to use miners from Batch1-5 or Batch7 at lower frequency.

good point my info was for a batch 1 and batch 2 miner.

screen shot is below  is my batch 1 miner

 fan at 30%
freq at 506
hash at 4175
temps are good
pretty quiet

lastly 0 hw's  as in perfect.

Thanks for the info. I set my miner up at home and then brought it to school with me. The computer i have here cant run ipreporter, so i cant find the ip to control the miner. What else can i do (I have XP and Mac)

I am assuming that since you are moving you miner around between different networks that you are leaving it set to DHCP right?

Alternately take the miner home & set the ip to a static one so when u move it to another network u can still get access to it to change the ip address to suit you network if necessary once moved

advanced-IP-scanner on XP
On Mac I use iNET-$9.99 in App store (bought it before for $4.99), works great

you can also download a program called FING, it works great to find all connected ip.  or just go in your router, and check connected devices.

what is the lowest block speed it will run on? i need to run it at 300 what kind of ghs do you think i would get for 1 board at 300? 750 ghs? going to replace the bad s5 boards with 1 s7 board and if possable use my s5 fan' and heat sink for a more efficent mine.
