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

[cloh76]

Why did they sell it at such a high price?

the simple answer.... because they can. The market will bare it.

At this point there are really only 2 options for home miners... Bitmain and SP and Bitmain is less than SP.

The Avalon 4.1s are nice for home miners as well.  Just a bit more expensive, but extremely quiet for 1+ TH/s.   I have a mixture of Bitmain S3s, S5s, and Avalon 4.1s.

I originally had 9 S3s at my office, but have since brought them home and replaced them with the Avalon 4.1s since they are much quieter and virtually have almost no sound at all since noise is the concern at the office.

Who's the North American supplier for Avalon 4.1?

Only place I know to order is ehash.com

How loud is this compared to S3?

Much louder compared to the S3.

If the S3 could be classified as a "comfortable" volume, then the S5 would be classified as "very loud" by comparison (off the top of my head, I think the S3's are ~55dBA, and the S5's are ~70dBA)

It depends on ambient temp also. My ambient temp is around 28 degrees C and the S3+ when it gets going is between 60 and 70db. Very loud.

Have had two S5 running flawlessly for three weeks and today experienced an issue (batch four, OE file system, CGminer 4.9.0, 306.25 MHz clock).  One of the two appeared to have frozen.  Perhaps half a day elapsed while both controller and Hash appeared stuck.  Discovered the problem by observing lower than expected Hash on Eligius and traced it back to the specific S5 by addressing it, whereupon it displayed the miner status page (without my logging in or selecting it), but was unresponsive to GUI selections.  I shut down the PSU for sixty seconds, fired it up again, and back to normal.  It now once again appears fine.

Noticed today my Westhash account was down ~2TH/s.  Did a visual on the miners and all appeared fine.  Tried addressing the two S5s and neither responded.  Power cycled both, checked their status (as well as the S3s), and all was back to normal.  The temps are 42/44, 46/46 and neither has been o/c'd (at least, not since Bitmain shipped them.)  The power supplies are CX750M with all four PCI-E connectors populated, the file system is the Jan 7 version, CGminer is 4.9.0, and the clock is 306.25MHz.

PS. Took a look around and it appears Batch 4 is sold out and I see no mention yet of a Batch 5.

Just discovered another failure, just one of them this time -- was frozen displaying the miner status page. Just raised both clocks to 312.5MHz, can't imagine why that would make a difference, but trying it anyway.

I have a feeling that its to do with westhash and generally altcoin mining as a frozen controller isn't a typical error we see. What could be happening is that on coin / block / whatever change, its flooding the controller with inappropriately low difficulty shares which is causing it to lock up.

Do we know that the described Difficulty issue is a known controller lockup cause?  This is not an attack, it's just not clear Bitmain has described what the misbehavior might be with a difficulty mismatch.  My view of this issue is obviously going to be different between a compatibility problem with Nicehash/Westhash Vs a generic problem.  If it is a compatibility problem, I think it reflects back on Bitmain to try harder to match their products to real world product usage.  My intent is to purchase a general purpose SHA-256d miner, not an exclusively BTC miner!  Mining is just too expensive to be limited to BTC.

how much high grade ram do you think the controller will need? 8gb of ddr3 or 4gb of ddr5.  the controller will cost $$$$. 

So the s-5 will not be 340-370 it will be   440-470.   A shit coin can have 10000x the shares of a bitcoin.

BTW I would like a better controller myself.

 Maybe a new quad core rasp pi  x 2 has enough to  do it.

It appears you're throwing numbers around.  I don't know what memory the S5 is using now and I don't know what the actual problem is.  Perhaps it's a little early for your speculations?  Let's see what Bitmain has to say and try to avoid speculation!

How safe is or would it have any effect on the miner if I were to have the ATX PSU run off a modified wave inverter?
We have 2 -6 hour power outages in SA.
I don't want to destroy the PSU or the miner in anyway.
I am getting mixed responses online about using modified wave inverters.

The following article seems explicit about the possible outcome in using a modified sine wave inverter on sensitive electronics.  I hope it helps:

http://www.civicsolar.com/resource/pure-sine-vs-modified-sine-wave-inverters

Thanks, I would love to get a pure sine wave inverter. problem is when they come into SA. They have a huge mark up.
I have some secondhand deep cycle batteries to test this idea on.
I shall test a modified wave inverter to see how that goesand if  i get any HW errors in the process.
Example. S5 Cost me ZAR4670 (S5+shipping+VAT+added BS). It sells here for R7400 used.

I wonder if an ATX PSU tolerates a modified sine wave inverter.  If it does, then I also wonder if the +12VDC output would be kosher for the miner?  I guess I'm sort of hoping that the ATX PSU would somehow modulate the modified sine wave and outputs a clean +12VDC.

hi, your ambient is 28C , may i know what are the temps on the asic chips ? reading on miner temp ?

When aircon is not on the hashing board temps run about 45 to 47 degrees C. Well within temperature specs. Fans run very fast though. 2900 to 3200 rpm.

[opentoe]

When I turn on my C1 (yes, the water cooled model) it kicks up the fan to high speed while it initializes and boots. Is that how loud a S5 is, or is it much louder than that?

I see several videos on youtube from users replacing their fans to silent type fans, is there a particular setup that works the best to quiet these S5's? I saw that one video where the guy was using a white silent fan from AAB Cooling, which I couldn't hear from it at all. What is everyone buying to keep their rigs more quiet? I assume they are adding another fan on the other end and switching both fans to other brands. There are hundreds out there, ranging from 1600-2000 rpm's mostly....what's the best setup for this S5 to make it quiet?


Thanks


Also, is this youtube post scam or someone really got his this silent. I'm thinking scam all the way.

Don't use cheap inverters, use the battery power. ATX PSU gives out over 12V anyway and if You take over 40A from lead-acid battery voltage will sink very fast near 12V nominal even if You have very big capasity batteries.

This isn't as simple as you make it out to be. You could probably power an S5 off a battery for a little while, but in order to directly power the miners off the battery you would need an automatic switchover system that removes the normal PSUs and connects the batteries when AC power is lost.

Really, depending on how you get your power the smartest play might just be to let the miner go offline during the power outage. A hash produced at time t=0 is worth the same as one produced 3 hours later when the power comes back on, it's not like someone's going to die on an operating table or a database will be corrupted if the power goes down.

Hummmm  interesting question...

we have not seen a masked S5 yet 

any pictures?

Does anyone use a dust filter on their s5? I have one on the push fan. It contributes a bit to the noise but what do you all do with dust?

http://eddiesilva.me/wp-content/uploads/2015/02/miners5-2.jpg

This is my S5 with a dust cover on it. its not the one that wraps around the fan but sticks on the front of the fan. Seems like it does a decent job. But really, how do you guys deal with dust? do you clean the miners out once a month or some other schedule? Doesn't dust contribute to increased heat?

[toptekk]

I love the ant miner , these have all ways  been the only ones i have ever bought to mine with, from my u1 and u2 days till now but they still lack one thing .

more choice in miners , can we finally get BFGMINER support for the antminer C , S series miner . .. Please Please !!!

I  Would have even bought the L1 if it had happen.I love mining any thing and every thing with in reason .

That's the last thing I would want to do. I saw a video on youtube where the dude has his S5 running with two silent fans and it's only 43 decibels. That I can live with. I doubt no one wants to spend another couple hundred dollars on a water kit. Just more work and watts.

[dogie]

The U1 is supported by BFGMiner but that's about it. Luke won't develop the S, C or U lines further without hardware and at the moment there really isn't any need for it. Cgminer is supported both officially and unofficially [Bitmain's] on two different branches.

Why specifically do you want BFGMiner? Its not as if we can run these on anything but official controllers running prebundled firmware.

No, an S5 is much louder. The C1's fan is an 'S3' fan which maxes out about 1600RPM lower and has a different sound profile to it on top.

I'd be very scepital about users 'silencing' an S5 without running it in a cold ambient or extremely hot. There are a lot of board components other than just the ASICs which require cooling and reducing airflow disproportionately affects these component. The closest you're going to get to 'silent' is 2x Corsair SP120s (high performance editions). They're not silent, but they're not horrendous either.

Well, philip is right. It doesn't matter how much resources you give a controller, if you try and use it inappropriately it will still fail to do what you want it to. This controller is designed for something around 200+ difficulty shares at the lowest, and even that will likely start throttling. If you're pool, coin or whatever else is throwing significantly lower difficulty shares at it then there's no way its going to cope, regardless if you gave it more resources and made it more expensive.

The best analogy I can come up with is like trying to dump a swimming pool's worth of water into your bath, then complaining to your landlord that he hasn't given you a big enough bath. There is nothing stopping you from mining other coins or on other pools, they just have to be sensible.
