Bitmain New Miner S7-LN 2.7T @697W discussion (Not official)

[in2tactics]

Ordered one last night and it's scheduled for delivery Monday! Pretty good service!

Came today as expected. Well packed in foam, all parts look brand-new. PS still had protective plastic on it.

Got it underclocked to 2.1Ghs to make it quiet and not so hot - though it was pretty quiet out of the box.

2.1GH/S??? I think you stopped all the ASICS but one. Good to know that the PSU'S are at least in good shape - was worried they could just go to the trash dump and find some random 87+s and put them on their miners ready to ship.

I guess he meant to say 2.1Th/s.

I did not even catch the 2.1Ghs. I only saw 2.1 TH/s in my mind. That is what I get for reading this stuff in the middle of the night.

Yeah, I meant 2.1Ths. Good little miner.

42 Degrees on the boards, and it's not super-heating my office. It's also sitting on the floor right next to my desk and the noise doesn't bother me at all.

I really hope that they make a S9-LN model as well!

The way it looks right now, the S7-LN is a really hot item. If they ever make an S9-LN, it'll probably be like how the S7-LN was made- right after the last few batches of S7. I think Bitmain will continue in the future with normal Sx miners and Sx-LN in the future instead of their old rackminer and U series - it's earned probably a lot more than either of those for Bitmain, and good for us too- the power supplies alone cost a ton, and the price is justifiable where you can just remove the psu when the miner's spent or you don't want to mine anymore. Great combo miner imo, better than the cheap 1 fan S7s they made.

[Ecnad]

Yeah the full S7's were too loud and drew too much power for my old house's circuits. The LN is just right for home mining, and I plan to get a few more to put in different rooms.

Would love to see an S9-LN also.

[philipma1957]

yeah I am having sidehack mod the s7-ln for me as are others.


looks very promising.

[cryptotore]

This might be covered already, but.. whats the noise levels at?

Cheers

I don't have a noise meter, so someone else will have to give you specifis. But for me, in a fairly warm house (73 in here right now) I would say it's no noisier than the small window air conditioner I have in another room.

Update: Used an app on my phone. Was getting 64-71 decibals at my desk (2 feet away) and 80 4 inches from the exhaust fan.

[IITravel01]

Anyone else notice it might be better to flip the fans around the other direction since the power supply exhaust is pointing to the front and will warm the cooler air in front of the S7-LN and be drawn back into the AntMiner?  Also is anyone pointing their S7 vertically like they did with the S5's?  If so, does it help?   Hard to believe, but I haven't been able to find one single picture or video of the rear of the S7-LN.  Anyone that has one, can you post a pic. of the rear.

[sidehack]

Right, the picture I posted of the rear 3 pages back had the fan removed and was more showing the boards than the miner.

Can someone tell me how many 6pin connectors are needed and what psu would be good to power one of these please. Currently got a corsair cx600m running some rboxes so got three pci connectors (one a dual molex to 6pin converter).

Thanks.

There is 7 PCI-E power connectors and it is recommended to use all of them.
Three PCI-E power connectors is way too little amount.
And you would need to underclock it if you are running it with ~600W PSU.
Based on my experiences with Avalon6 you could try with 2 connectors per board and one for controller -> total of 5 PCI-E connectors and make sure that the connectors won't heat up. Just make sure that the wires are at least 16AWG.

Are you asking this because you have other plans for the Enermax Revolution 87+ 1000W PSU that comes with this?

edit: Oh, I saw your posts in sidehack's thread and realised the reason.
For his version of S7-LN Corsair CX600M would be enough but you still have quite little amount of PCI-E connectors.
5 would be great.

[sidehack]

If you're going with my standard settings, the miner would draw at most about 430W wall. So that's no more than 400W DC, which means probably 20W controller/fans and 190W to the boards. If you've got 16AWG cabling that can be done with one cable per board, but two is better.

Thanks for the replies guys 

Funnily enough I bought a set of custom cables (16awg) for my old corsair rm1000 which I no longer have, so I could utilise those as im going to have to buy a new psu for it anyway due to it being shipped without one to save weight

 Hello guys, i have oder 2 s7 LN ,they are in transit,i cant wait till tomorroww

[sidehack]

So it's a good thing I ordered an extra miner on the first hacked group buy. I kept one because one of the boards wouldn't run stable at or below 630mV cold, so I pushed it up to 640 and left it on my shelf. I say "good thing" partly because of that, and partly because the PSU on it started misbehaving after about two days. Now it doesn't work at all. I switched it over to my known good test S7LN and still the supply trips out as soon as it lights up.

oh okay it sounds like the two I will send to European buyers will be okay using their own supply rather then the oem.

If you need some of the supplies  you can send all three modded s-7ln's to me sans psu's.



My one  and the two for Europe without supplies.  Hold the 3 as psu's spares for  the other buyers.

    At this moment  I have  8  spare psu's  all better quality psu's  plats and tits.  
 Sounds wrong so make that  platinums and titaniums.

Is there any way to disable the beeper if the miner loses network connectivity?

Bought myself a evga 850 p2 on your recommendation. Hooked it up the the old rboxs I've got and it's saving me 25-30w already lol. Nice bit of kit. Thanks for sending me the links philipma1957  

[generalt]

Looks like they're finally sold out of the S7-LN.
