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

My opinion:

Yeah man! buy more hardware! pump the wallets of the manufacturers by underclock and buying more hardware...

I think that is exactly what the big players do.  They probably buy bulk and get a discount and then use that price advantage to downclock underclock and save even more w/gh.  Then due to either business miners having to sell BTC to pay for costs in fiat, and the relative cost of mining a BTC comes down as the total cost per btc lowers with more efficient miners.  This is offset somewhat with the increased network difficulty, so I would think that the price should gradually begin to rise.

Just got S5 and it is hashing steady.  The noise is not bad.  From the reviews I thought it was going to be much louder.  Its a higher pitch for sure, its small in size and not really overwhelming.  I have one setup in my bedroom and don't think it will be a problem. 

I'd suggest you get your hearing checked.

Mine is in the sub level basement garage of my apartment building, and anyone who walks down to the basement garage can hear it (my garage is the furthest away in the basement)

dB readings:
Standing outside my garage door - 7meters from it - garage door, car, a wall of boxes between me and the S5: 59dB
1meter direct line of sight from the S5: 69dB
1foot above the S5: 77dB

The heat sink exit metal temp reading is only 39degress - so maybe the fan is over compensating? ...

Noise levels are relative for different people. I worked 5m away from an SP10 for 14 hours a day for about 4 months so I have a different reference frame then say someone who has only ever had an ASICMiner Cube.

Seriously? You gonna say that?

I posted dB readings ... so my post is quite specific, not a random vague "I got used to loud noises from an SP10 and now I'm deaf" comment.

Edit: Oh OK - your doing paid advertising spin - I didn't see your stupid bias comments to ckolivas before:
https://bitcointalk.org/index.php?topic=902305.msg10056977#msg10056977

I'll check with Bitmain directly and see what they have to say.

Kano, you're being really aggressive the last few months and there really is zero need for it. My comment was in relation to you telling someone else to 'get their hearing checked' just because they had a different opinion on how 'loud' they felt the S5 was.

Take it down a notch please.

WTF?

I posted specific measured details, meanwhile you posted a reply opinion based on you now being deaf.

Seems what's becoming a usual comment for you is necessary.
Try actually reading my post ...

It's not quiet, and I don't have a db reader.  But it is definitely not louder than my vacuum cleaner.  And I'm somewhat used to prior miners fans going.  This miner will probably go in another room for convenience and electricity purposes, but I'm a little bit biased.  In terms of having a closed metal frame and dual fans.  Personally, I like having more metal, they make my miners feel more solid and durable.  But with the pace of new technologies these miners are obsolete within a matter of several months, so its not necessary to have battle-ground metal plates on the thing.  Being able to stack them is raised, but I would imagine commercial data centers have all the necessary equipment to efficiently setup S5.  Maybe for homes and garages it would be easy to stack several miners on top of one another, like the S2 and S4's.  Even so, I'm at the point where I'd either need to find a new place to live or rent space commercially to increase my mining, and I'm not really sure that I want to do that.

Is it intolerable? No, it isn't. But in my house I couldn't hear my wife yelling at me from the other room with this thing running next to me. Yes, I could probably hear that she was yelling something if she wasn't too far away, but I wouldn't be able to clearly understand her due to the noise level. So it just depends on what your standards and expectations are, and how loud your family can yell. Perhaps the white noise will be a blessing for some.

Well hello guys .

I've  been laying low the past few months

Happy New Year...BIG things coming this year

What is the process for transferring coupons?  Is that donate button supposed to do something?  I mean I would assume so but mine doesn't.

dogie- Please reply to this. Donate button not work mine as well.

Why is the price on the first page here

Today, Bitmain is proud to announce its 3rd generation chip in conjunction with its 9th product: the Antminer S5. It is 450 USD 341 USD per unit (excluding shipping) and will ship starting on December 27th January 12th.

Bitmaintech website is the S5 price Price:       358 USD  [15% Discount Off] ANTMINER S5 BATCH 4

Yesterday, the price was still   341 USD
 

[aclass]

now it still says 15% off but price is 358

Not so excellent. Janet, please provide us also with airflow (in CFM) of these fans.

[Rabinovitch]

Have you tried closing in the top so the front fan air flow is kept within the frame and exhausted out the rear? Also, how about reducing the airflow above the heat sinks (reducing the upper front fan opening) so as to improve cooling efficiency (greater air flow through the internal heat sinks)?

Beyond that, how about an S3 fan both on front (push) and rear (pull)?

None of these seemed to make any significant difference. The loudness and temperature seems almost entirely dependent on the one fan on the front.

Damn... I was planning to do this (close the top of S5 case to provide more directed airflow) with my test unit that arrived much later than to other forum members...

But I still have a couple ideas on how to play with S5.   Can't wait to get it in my hands (it's not depends on me unfortunately......).

Started running  mine at Freq 375 getting  1.23+GH and reading 635W at the wall with a RM1000 Corsair 115V.

After 28 hours one board dropped and started showing x's, after a reboot that didn't help I  reset the freq back to default of 350 and its seems to be doing fine now. Getting 1155GH with temps at 48/47 fan 3480 and reading 592 watts at the wall. Not sure why that board dropped off at the 375 setting as the temps seemed fine at 50/49?

Want to order another one but waiting to see which is the right price?

[aurel57]

Just seen where Bitmain has crossed out the 9v feature for undervolting? Was this discussed here and I missed it? Was counting on this to work in the future.

Notes
1.   Power consumption figures vary with your PSU’s efficiency, the ambient operating temperature and the accuracy of the power meter.
2.   PSU: A power supply unit is not included, and you will need to provide an ATX PSU. There are 4 PCI-e connectors for +12V DC input and all four are required. Do not connect more than one PSU to the same hashing board.
3.   When better power efficiency is needed in the future due to higher network difficulties, you may want to buy some special PSUs 9V DC with more than 10A output, which will allow you to have a 0.2J/GH mining efficiency, but at lower hashing speed.

I have to say, the reports on the noise of these things is not exaggerated. I had one set up in my basement last night for testing, and I had to go shut it off to go to sleep. I've at various times had an SP20 down there, a dozen S1s at a single time, a couple Habaneros with 250CFM Delta fans, and a half dozen 5970s running at 100% fan along with other GPUs back when that was a thing. Never had to turn something off at night before.

I'm really going to try to remember to bring a measurement mic home and get the spectrum of the noise, it seems extremely high pitched at full speeds compared to a lot of other fans.

Have you done any undervolting yet?

Not yet. I only looked at it briefly and it didn't seem to want to start up. Could have been a network issue though.

Oh, along with that I'd concur that the fan profile is stupid on these things. The one I have in my mining location has ASIC temps of 42C, and the fan is still spinning at 3360RPM. A lot of headaches would probably be avoided with better fan control.

Or maybe the 9V undervolt does not work? Figure there is a reason Bitmain has crossed it out on page 1.
