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 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 |

What are you waiting for? Pump it up to 700mhz

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

honestly thats what you get for buying cheap chinese shit man good for you, next time don't support a company that sends out garbage, and works to destroy BTC thru their mining practices. good for anyone with shitty equipment from them |

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.

I powered it up with the paper clip method.

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.

Could someone drop a video on youtube with one of these running in a room by itself? My buddy wants to see how bad it is because he is considering ordering one. He couldn't bear his S7, so I took it in for him for a profit split.
If possible to show an S7 running in the same room alone as well for comparison, that would be super =)

I heard that the fans have a speed of ~3000rpm, so could it be like back in the Antminer S1, S3 -days?
edit: okay, good point Real-Duke
