2.7TH is dead on for 90 chips at 600MHz. Given that a lot of the listing looks like it was copied directly from an S7 page, saying 700MHz instead of 600MHz wouldn't be the only error in the info.

Cool, quiet and up to 1TH pod miner, on sale now!

Yesterday I received s7 silent. Chips frequency 600, temp 45/48 but I have cold room. Fan speeds 2700/3000 and I have to told you that is really silent.

So, I bought one of these. Mostly because I want to play with volt adjusting and I actually have need of a beefy ATX PSU.

 That's what EVGA G2 1300s and Seasonic X1250s are for.

 8-P



 The listing error would be ... more than a bit in character for Bitmain on their S7 varients. Anyone put a wattmeter on one of these puppies yet to see what the REAL power draw looks like?

     It looks to me that a clock at 540 vs 600  would really let fans run low. Hash would drop to 2490 vs 2770
  I wonder if sidehack could figure out a voltage drop for these.
 Remember how the s-1's could do  140gh at 170 watts  vs   200 gh at 400 watts  with a simple pencil mod.


I see BTC as the super highway and alt coins as taxis and trucks needed to move transactions.

I don't need a PSU that beefy. Honestly a good 650 would do it, so a cheap 1000W is probably about right and I don't want to gut my Dragon.

I'm going to have a lot on my plate starting about Tuesday of this week and going through the forseeable future, but I'll probably still make sure to take a day and jack around with this miner as much as I can. The BM1385 should be capable of going below 0.2J/GH board-level.

New S7-LN running

Saving space with pic

Thanks for sharing interesting to see this out in the wild.  I would love to see more pictures of this miner.   Think you can get the front/back/sides with a camera and post in thread?  Either way thanks again for sharing.

this miner looks like a nice one for office use.

set freq to 540  it will hash 2500gh  use just over 625 watts.  be quiet  .  looks like a good fit for some.

I think somebody already figured out a way to undervolt these by doing a mod. It ran I think at 0.22w/ghs

It should do 700M no problem (doing 3.15 TH/s), but since the fans are only running at about 3,000rpm, it's not advisable.

I recived my 3x S7 LN today
2 of them are working fine,
1 of them is not powering at all
Can anyone help me ?


I checked the power cord and it is working correctly on other PSU
I switched the PSU on first and then the JUMPER on
Miner not powering at all

Any advices ? WHat should I do ?

It's a brand new miner that I just recived a few mins and not working at all
I don't like this, and I don't want to send it back to warranty because it will cost me so much to ship and lose so much time

Later Edit : I was thinking that it could be only the PSU that is not working right ? Because if it was working fine it should have started even without the miner ?

Later Later Edit : Switched the PSu with one of mine and it is working
F*cking Bitmain send me an already burnt PSU

Cheap can refer to price or build quality. Bitmain didn't used to sell either, but started going cheap on build quality with the S5.

Just got word that my unit has shipped and should arrive Wednesday. Hopefully I can take some time in the short term to jack around with it. Might even see if there's a way to hack the PIC for voltage adjustment without requiring hardware changes.

   I just ordered one from HolyScott, I can't wait to see if you come up with a way to cool these down a bit more.

I don't really have a timeline, unfortunately, given how full the plate is with manufacture, manufacture, manufacture and dev. But I'll do what I can.
