ANTMINER S5: 1155GH(+OverClock Potential), In Stock $0.319/GH & 0.51W/GH

[Biodom]

It saves an alarming amount of weight by opening up the top and bottom, as well as replacing out the metallic sides. The S5 is a total lightweight compared to the S3. And that means less steel being shipped round the world.

Replacing out the metalic cover with a plastic /perspex one sure saves weight, but how much weight would a plastic / perspex top and bottom add to the overall weight of the S5? (rhetorical question so you don't have to answer 'cause I know it is insignificant)

+1. while a bottom isnt really necessary (but whats $1 of plastic that weighs 60g?) a top would definitely improve airflow. Ive seen an improvement in temperatures but putting a few clear strips of tape over the top to improve the wind tunneling, and a top cover is only $2 or less of sheet plastic like the sides. huge improvement over the tanky S3

To continue...(if you know your tank facts...with nothing else to do):
1. S1 is Mark V (WWI)
2. S3 is a "Tiger" (heavy)
3. S5 is T34? or will be due to vast numbers produced
4. SP20 is M3 "Lee" (light, maneuverable=adjustable)
5. SP30, 31, 35-Merkava (different time period), not WWII

i cant understand why this company keeps releasing miners that wont make a return??

Free AC makes a huge difference. We run an ASIC farm and were lucky in that we negotiated 1600 AMPs of power included in our lease, years before we got into (or before BTC even existed).

So I think it really just depends on your situation. For the average Joe who pays regular rates for AC, mining is not a game to get into.

Jesus, 1600A of what, 600V 3Φ?

Mostly 110 20 amp with 20 amp recepticles (orange grounded T), but the core room is mostly 3-phase 220 and we have distros. The building is 11,000 sq feet, 2 levels, so the panels are broken up, for instance a single upstairs panel has 30 20amp 110s, and some 15amps + a 2 3 phase (I believe 60 amps)/30a/220.  We're a film production facility so it's built to draw lots of power for studio lighting, edit suites with large workstations, etc. The 1600 is in addition to the AC breakers - not sure what those are, I believe they are 480v.

When we signed the 10 year lease 6 years ago - no the owner I don't think had any idea we would be mining bitcoin and drawing that kind of power 24/7. But it's written into the lease, and we insisted all copy from the lease be struck regarding "reasonable use", simply because I didnt trust that language. We said the only way we would sign is full service, not triple net - meaning power, taxes, cleaning, everything - is included under 1 flat monthly payment with a 3% increase in our lease payment every 12 months.

That said - 6 years later, we've built out quite the farm... Lots and lots of S3+s,  just ordered last week 24 of the new S5 units from Bitmain, and we've got roughly 60 280x cards, and 40 270x cards - currently not running simply because we shut them down when alts started to become to much chase and not enough profit. We've considered either turning them back on or liquidating off the cards and mobos, psus, and cpus. Its amazing how timeconsuming the rigs are - anyone who thinks running that many gpu rigs is simply set up and run should think twice and run. It was a constant hassle of one issue or another every other day - pool down, frozen computer, hardware errors, etc.

So who knows. If we strike them back up our landlord will be less happy.

On the bright side I think our landlord understands that we are making money - and paying our rent on time every month. And it's not is place to say how we do it. We could just the same turn the studio into a 24/7 news outlet with a main studio and multiple inserts - drawing likely just as much juice - but who wants that hassle   In closing - our landlord is well in the profit from our lease - our monthly rent is $27,000... so while he does roll his eyes when he sees them running we've convinced him keeping us in the green is good for all parties.

Unfamiliar with the Merkava, but I do appreciate tanks!  Interesting to see a Soviet product suggested, they made utilitarian and affordable tanks -- much better in the mud than the Panzer divisions.

Im not an electrician, but this is an example of 1 of the panel breakdowns. Just for the person who said my claim seemed suspect. This is one of many panels throughout the facility.

The bottom is kind of important if you stack them on their side.

Does anyone know what a reasonable max temperature these guys could be running at ?

Is 70C way too hot ? Trying to keep them under 65C right now, but would be good to officially know the range.

Also, found a bug. Changing the frequency resets "Beeper ringing" to it's default checked state.

I'd be comfortable under 60 degrees myself.

Some fans I'm going to try playing with...


EDIT3:

Much better

What are the models of those fans?

RASKUL's S5 REVIEW

please navigate via the link below to read my independent review of the Antminer S5.

http://rgsneddon.thescribe.eu/#post117

synopsis
A good little miner which worked right out of the box and hashes at the stable advertised rate.

The ultimate question...

Q. Would I recommend it?
A.Yes, I would recommend this miner.

Raskul I agree it is a good miner I will read your review. I read it and it is fair and accurate.  Here is my review

https://bitcointalk.org/index.php?topic=907219.0

only just got around to reading your review Phil.

I'd say it's about right, and you have far more ability to do in depth, than i. thanks for sharing

note: my host is down at the moment, I should have just made a new thread for my review but I was afraid dogie would tell me off for spamming the forums - because he's so unbiased and has a balanced opinion on all manufacturers

If only S5 was in the same case like SP20... Or like S3...

personally, i don't care, but closed case looks more 'retailish', I agree.

It saves an alarming amount of weight by opening up the top and bottom, as well as replacing out the metallic sides. The S5 is a total lightweight compared to the S3. And that means less steel being shipped round the world.

Dogie, it's an absurdity. Let's ship it without fan maybe?.. Or without heatsinks? Less weight will be shipped around the world...

The product should work out of the box, and this S5 needs reworking in most cases (if home miner can't place it in the basement of in the data center).

When I speak about closed case it's not about 'retailish' look, I mean only better cooling (and less noise) if the case is closed.

And less danger of setting your home on fire.

Also i noticed that Bitmain went back to the "old" S3 heatsinks? Cost?

What are the models of those fans?

Antec pull fan : http://www.amazon.com/Antec-TriCool-LED-Cooling-3-Speed/dp/B00066FHEW/
Thermaltake push fan : http://www.amazon.com/Thermaltake-Blue-Eye-Adjustable-Control-AF0026/dp/B003IWN23O/

One of the two miners I received is running hotter than the other, using identical fans for each unit.

Overnight, one of the blades curiously went xxxxxx xxxxxxxx xxxxxxxx xxxxxxo running at stock 350 with the temps at 63C. Rebooted and it's working OK again.

Will continue to keep an eye on it, but I suspect I might need to slap on the original stock fans for that one unit.

[PsychoticBoy]

@BITMAIN:
Do you have plans to change the fan for batch2?

Cheers

Oh chain design, thou art a heartless bitch...

Please do keep us posted on this issue...

PS. I second PsychoticBoy's question.

Batch 2 likely won't change because those orders were made for a certain product. Other solutions are being looked at.

[unofficial] If you can get it back under 65 then that should be fine. Its more about balancing your premature death risk (ie 12-60 months) than worrying that its going to melt or anything as the 80C cutoff exists there for a reason. I'm not sure you'll get an official reply on this because we're talking about modifications which officially void the warranty anyway.

Bug reported, although I think I've seen this one on S4, C1 etc as well.

I just order new fans for my Batch 2. I have a couple ideas I want to try when it gets here.

[whisky7]

Anyone have any ideas what to do with ALL my Antminer S1's

[sbogovac]

Disassemble them, rip off the heat sinks, reassemble them using dividers and a minimum amount of fans. Then down clock them to the most efficient power to return ratio...

Looks something like:
