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

[SLEI]

Just Curious...

How many of you guys running S5 over clocked?

How is the result on power consumption and HW error side?

Also, OC, you definately need 4 PCI-E plugs connected but for normal stock operations anyone running S5 with just 1 PCI-E connection to each hashing PCB?  We know it works, but again, being curious if anyone is successfully doing so on the customers end.

Please DO NOT burn the chips while OC them.  Keep them plenty of air flow and keep them as cold as you can be.  RMA techs may birth a cow or two when they see burnt BM1384 chips  

And if  your Ants happen to be a lucky one to find a block or blocks, Show US your Ants Porn!!!!

I heat my garage with 2 S5s at 400mhz room temp is 22 C miners about 48/54 47/52 C both have tops covered.

Cooler miner has S1 fan pulling at about 3400rpm, original is running about 4000, 100rpm faster than miner with only one original blower.

DPS-600PB server powers at both and taking 700W from wall, I have tested only one miner for power usage. 

Hashrate little over 1300, 1325 to 1304, BTCguilt shows bigger values upto 1350. I tested more mhz but voltage drops and I got more errors, idle voltage is 12.5V and 400mhz 12.2V.

I got more PCI-E connectors and I test 2 powers on one miner, these server powers have current share pin so very easy to run them parallel. I bought Big pile of server powers 15$ eatch and 1,2kw "ordinary" PC powers cost in my country about 350$.

S5 now available on Hashnest:

https://www.hashnest.com/

Price is the same as on Bitmain's website (~$370), no shipping cost, and the maintenance fee is ~$0.095 (9.5 US cents) per kWh.

Will that ROI ?

If the buying stops,  the killing stops too.

[dogie]

I can absolutely guarantee that you didn't find 6 BTC blocks with a single antminer. I had various generations of Bitmain miners "find" dozens of blocks according to the miner stats. Unfortunately they were simply errors on the stats page.

Hummmmmm 6 blocks.  It can be possible but if you found that many, you might want to go buy a lotto ticket just in case.  Your luck may be super high!! 

Or, whoever is renting on nicehash is altcoin mining.

I read back a few pages looking for information about changing the fans on the S5's but was unable to find any information so I am starting the discussion over.

I received my 2 S5's yesterday and my parents promptly said "no" to the noise going on in the backroom from them.  So now I need to replace the fans and my thinking was just to put 2 of them on either end like the S3 and call it good.  I noticed on the controller for the S5, there are 2 4 pin slots so I figure this should be fine, but wanted to double check.  I am thinking of running out and getting these today...
http://www.microcenter.com/product/423765/Air_Series_AF120_LED_Red_Quiet_Edition_Twin_Pack
and putting one on either end of each S5, but they are 3 pin connectors, should that be fine or should I find ones with 4 pin connectors (I thought 3 pin can plug into 4 pin slots?)  Also the airflow is 52.19 CFM, should that be sufficient to cool an S5?

Thanks in advance, I appreciate all feedback

They should run fine with two of those fans using the 3 pin connector, but you won't have speed control. Depending on your ambient you might have to throttle down the speed quite a bit to keep the miner cool.

That was my thoughts on the 3 pin connector.  Thanks for affirming. 

Forgive me for not understanding, but you say "throttle down" the speed to keep it cool, wouldn't throttle down refer to slowing the fan speeds, and raising the temp of the miner?  My ambient temperature isn't high, and they are in a very large space to dissipate the heat, so I am not too worried about that being a factor, just confused on what you mean.

Thanks for the feedback though.

Sorry, I meant turn down the frequency of the miner. There's no provision for voltage control with the S5, so power use scales pretty linearly with frequency. Those quiet 52CFM fans probably won't be able to dissipate 500W even running full out without the temps going nuts, so you might have to turn down the frequency significantly to keep everything from getting too hot.

Ahh that makes more sense, thank you, guess I will look for some fans with better airflow that are quieter.

Thinking this one now...

not necessarily enough as that fan produces just 93CFM.
I used NF-12 3000rpm Noctua fans at ~110CFM ($24.6) and they only allow for ~325/1070 Gh at safe 60C when used alone in push position.
Added scythe ultra kaze (not PWM, ~$13) for pull and 337.5/1100Gh is possible at 60C, maybe even full speed if you have lower than 30C ambient
ultra kaze somehow did not work for push.
The whole setup is ~55-56dB, which is much better than default (more than 72dB).
if you need screws for connecting pull fan, then go to metric screws section at Lowes and get M4.-0.7 (45 mm-will allow for grill).
these fit very nicely.
I am really looking for quiet fans and next on my agenda are delta AFB1212SH (25X120X120mm). these supposed to produce just 46dB with 113CFM-I will believe it when I use them. Unfortunately, they are available only for slow ship from europe or china on ebay or amazon.

[alienesb]

I tried two of these http://www.amazon.com/gp/product/B00E20SSWQ/ref=oh_aui_detailpage_o04_s00?ie=UTF8&psc=1 but they weren't really enough and instead went with one of these in the back and a Delta up front using these to cut down the speed/noise: http://www.amazon.com/Zalman-Fan-Speed-Controller-FANMATE-2/dp/B000292DO0/ref=sr_1_8?s=electronics&ie=UTF8&qid=1423845288&sr=1-8&keywords=fan+controller

Right now my five units are around 58-64C in a 73F basement.

Hi, BITMAIN,

We noted that AntMiner S5's are having some minor issues when mining some particular low-diff and fast-work restart coins. Users which are mining on our NiceHash/WestHash SHA256 pool are seeing up to 5% rejects in particular periods of time when these miners are working on low-diff and fast-work restart altcoin orders. Could you let your technicians to look into this and provide some patch in the future firmware? Could this be due to too weak controller not being able to process all shares when working on low-diff and fast-work coins?

Kind regards,
NiceHash

Can anyone tell me what the f* going on with my S5.Its started to beeping this afternoon and keep going on.
I'm really over with this stupid rip off bitmain tech company.They dont have proper user manual.And no one knows what are the leds mean on the side, on the top.
I'm getting more and more random beeping.Can I send it back and they reimburse Me?

[alienesb]

Beep probably means it lost Internet connectivity.

switch the PSU off, wait 20 sec, switch it back on.
once you will be able to connect to miner in gui check if you have jan 7 firmware as it is more stable.
as OP said, beeping simply means that you lost internet connection to your miner. it happens, no biggie.

[727miner]

I wanted to give a shout out to BitmainWarranty. One of my S5's boards stopped hashing earlier this week and they were quick to communicate with me to setup an RMA. I shipped it to Denver (it still hasn't been delivered to them yet due to a USPS delay) and low and behold I just received a brand new unit this afternoon! Great customer service, thank you!!

As others have said, beeping is just a notification that you've lost connection to the pool / internet and its sitting idle. Restart the miner and check your settings, posting them here if you need help. You can also turn the beeping off. A full user manual is provided by Bitmain here.

If you need any help, let us know.

What do you consider low diff? As miners get more and more powerful, setting appropriate difficulties becomes more and more important. For example attempting to run a miner at 128 which is appropriate at 2048 would create 20x the load on the controller.

For anyone looking to put slightly quieter fans (that still get the job done) on their S5, here's a dang good deal on a pair of Delta AFB-1212SHE.  This seems to be a popular choice for reducing dBs while still keeping temps under the 60C target.

Two fans for 20 bucks shipped.  Not sure what's up with the 4-pin connecter, something looks off about it.  I just placed an order and will update when they come in.  Hope this helps someone.

Don't use the quiet editions, they really are rather week and I doubt they'll be sufficient at any sort of ambient. The SP120 performance editions are much better suited as they're moderately high pressure but still at an acceptable noise level. I use them all the time to 'silence' various miners without trashing their cooling [Without affiliate] [With affiliate]. There are also PWM versions if you think you'll need it in the future [Without affiliate] [With affiliate].

Even slightly is a stretch, those things are vicious 4000 rpm fans [1.6A], I've got 6 of them on a HashCoins Ares and combined they're the loudest fans I've had on a mainstream miner.
