Topic: ANTMINER S5: 1155GH(+OverClock Potential), In Stock $0.319/GH & 0.51W/GH - page 254. (Read 451048 times)

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.

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

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.

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.  

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.

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

+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

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)

Actually, I think bitmain got this a bit wrong, but the good thing with them is that they listen to ideas (and test them out).

In the shape the S5 ships, it is NOT very well suited to home mining, but then again they had to be competitive pricewise so I think they tried to gain efficiencies with the cooling system they deployed on the S5 and by reducing weight and components, but ended up with a product that is neither well suited to home mining nor very well suited to commercial mining (the latter due to its lack of stack-ability!).

Having said that, the S5 can be made a lot quieter by replacing the stock fan with a quieter PWM one OR reducing the voltage to the stock fan with a resistor; you'll then need to add a second pull fan, and possibly have the top and bottom closed off.
Come to think about it, bitmain could engage a partner (similar to their liquid cooling one) to offer S5 to home upgrade / downgrade kits (whatever that qualifies as) after testing that include a pair of quiter fans + top / bottom covers (Not really worried about the covers as I can use card-board). Of-course, that depends on the longevity of the product line.

newbs don't want to see the machine "insides", but if you want to grow business, you have to sell to them as well. it is pure psychology/marketing.
make a cheap plastic top, then explain that top might or should be taken off during operation.

To answer the question of 'why do people keep buying this hardware?', I present you with



10. Alt-coins
9. consistent BTC influx, which bitcoin has proven price spikes. = HOARD until you get to your profit point.
8. Hoarding BTC for the end of the world
7. Hoarding BTC for their loved ones
6. FUN HOBBY
5. Tinkering with electronics - guy stuff and (some) girls
4. Free electricity so it pays to mine
3. Realizing if they only 'make my money back' that it was worth the adventure because you are now part of the new monetary open source world while contributing to the blockchain, community, and population
2. sticking it to the man while not getting stuck by the man

aaaaannnnnddddd the #1 reason why people keep spending their money on miners......








1. Need something to do bc the wife won't stop shopping and spending all his money so why not throw it away into something that might get a little bit of a return and not hang in a closet for 2 years with the tag on it!

Yeah, that lease is suspect, one of you got or could get screwed. Amps is current (not power), so you could increase voltage and then tranform it down and multiply your amperage after the meter. 1600A of 10KV would give you 16MW of power.

Hey, I didn't start it. Pokey's the one who wanted to make sure people didn't cross the streams.

Jesus, 1600A of what, 600V 3Φ?

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.

Is that... is that a ghostbusters reference?

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.

A lot of people don't know how to do that, or have crappy ISP modems as their gateway that just give MAC and IP; just trying to help the newbies.

well good luck to them in life

Because people keep buying them and they make money?
Why does everyone insist that this company (or any other) change their pricing to suit them? Either buy it or don't. Your purchase or lack of purchase is how you vote on their decisions.

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