Aaaah that makes sense. Thanks alh
So what does the "LN" stand for?
I assume it's for "Low Noise". Or perhaps "Last Nacho" (i.e. something related to the end of the S7 line).
So what does the "LN" stand for?
Its clear that bitmain is only out to make a quick buck since its introduction of the S5. I've read nothing but bad news with all the S7's and now S9. As a owner of S1,S3 and S5 and can say that their attention to detail after the S5 is questionable. Ofcourse what happened after the S3 was they didn't care about the noise.
I now have an Avalon 6 and think people should switch.

And speaking of lemon power supplies... another one just toasted and tripped the breaker with it. Won't even power on. I scabbed the fan from the one dead one into the other so that one's probably okay, but I'm still down at least two, maybe three.
Also when I was swapping fans I pulled a dead moth out of the one.
Thanks a friggin' lot, Bitmain.
Also judging by the state of the screws and warranty stickers, three of these PSUs had been opened before they ever got to me.
Well, we knew the PSU'S had mostly been used before they got into the miners; it wouldn't be worthwhile for them if they were completely new. They were probably repaired by Bitmain, when suddenly they had an idea to sell these worthless psus with a miner, OR they were broken and they repaired it just to sell them. These could be the PSU'S they use in their farm.Also when I was swapping fans I pulled a dead moth out of the one.

No surprise either that they seem to be priced in USD instead of BTC, they have no use for these PSUs and they'd rather just make a crappy bundle out of it.

Anyone else turned their fans around (so the heated air exits forward) and can confirm a noticeable decrease in fan noise?
Speaking of "lemon power supplies"... looks like one of 'em has a fan that wants to chew itself up.
I can confirm sidehack's observation regarding S7-LN availability. I started at the top, and was able to get down to the point of actually purchasing one. It still appears to be priced in USD and not BTC. Quoted price is $291 plus shipping.
A much better deal than the A6 I bought earlier this year.

I don't see indication that it's out of stock right now.
Also, might have another lemon power supply. It was a bit sketchy and boards dropped out, but it appears to be running fine on a server 750. If so, that's 2 PSUs in 15 already. Not good odds.

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.
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
yeah evga makes a ton of good psu's for mining. I am glad it is working out.
Looks like they're finally sold out of the S7-LN.
I know! What a bummer. I was looking at picking up two more.

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

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