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

[sbogovac]

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

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:

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

Cheers

batch 1 = batch 2 = batch 3 there is only 1 batch here formed by 3 artificial ones! maybe ''batch'' 4 is the same

Did any1 with 2 s5, try to connect 2 more blades to one s5 for a total of 4 blades per one s5?

Im just wondering with these all new miners coming out, is there any money to be made via mining anymore?

Bitmain should make a new AltCoin with high profitability  price like   ANTCoin

send me couple of them.. need for heating my house

How many you got?

Definitely, but it requires low electricity/hosting costs.

[bitcoin4eva]

What kind of ROI time are we talking about?

[Syke]

What kind of ROI time are we talking about?

Very rough numbers because everything changes, $150/mo income, $50/mo hosting, $500 purchase price = 5 months with static difficulty, 6 months if the difficulty rises slowly.

Even if all batches ship near the same time [speculation], they'll still ship sequentially. So the start of batch 1, then batch 1, then start of batch 2, batch 2 etc.

doesn't matter!

what really matters is not the shipping date, but production date!

and the fact that ~2months ago, s5 was in the farms and mining till now!

My story I am already losing a ton of money, I got 50% DOA units and they won't accept a return. Only to put bandaids on the units and ship them back to me. Mind you they had smoke pouring out of them and made my house smell like burnt electronics. That will make you think twice.

The photo you posted just showed a cap that could have been pried up off the board. I saw no evidence of electrical fire. You are so rabid about thia I am starting to doubt your story. Yes, I did believe you at first. Some proof needs to be given of your purchase, return, etc. if you want any credibility in this forum.

[bitcoin4eva]

Yea I've been mining earlier, it was hard even back then even though I didnt pay for my own electricity.

I posted this in one of the review threads, but thought it should be also posted here.  

"For those looking at aftermarket fans, the Silverstone isn't the only 140mm fan with 120mm fan holes (although it's the only one 38mm thick and probably the best by far http://www.silverstonetek.com/product.php?scase=c_140&pid=366&area=en ), there are a few others.  Those will move more air at a lower RPM causing less noise.  One thing you may need with some aftermarket fans though that I've learned is that the screws sticking out of the front and back can cause interference with the blades, so something like these can help.  http://www.amazon.com/gp/product/B00NODDHLY/ref=oh_aui_detailpage_o01_s00?ie=UTF8&psc=1

Here are a few of the fans I've found.

http://www.amazon.com/gp/product/B00Q8RLCBU/ref=oh_aui_detailpage_o01_s00?ie=UTF8&psc=1  shipped from China so they haven't arrived yet.

http://www.amazon.com/gp/product/B0078IWS6Q/ref=oh_aui_detailpage_o07_s00?ie=UTF8&psc=1  white LED and good airflow but not as quiet as others.

http://www.amazon.com/gp/product/B00B1WQ4VA/ref=oh_aui_detailpage_o06_s00?ie=UTF8&psc=1 if you happen to need a shorter fan, not high airflow but pretty quiet.  Optional Static Booster:http://www.amazon.com/gp/product/B00HRJ550W/ref=oh_aui_detailpage_o05_s00?ie=UTF8&psc=1  which makes it as thick as a typical one so this option isn't really useful.

http://www.amazon.com/gp/product/B00G8GUE74/ref=oh_aui_detailpage_o01_s00?ie=UTF8&psc=1  Similar to the Prolimatech above but spins a little faster.  (Silverstone has a new similar one called the FW141 but I haven't found it for sale yet)

http://www.newegg.com/Product/Product.aspx?Item=N82E16835856013&cm_re=140mm_fan_120mm-_-35-856-013-_-Product  Quiet but not a lot of airflow.

http://www.newegg.com/Product/Product.aspx?Item=N82E16835856015&cm_re=140mm_fan_120mm-_-35-856-015-_-Product  Same as above.

Some of these are right up to the bottom of the network port on AntMiners, so you should use network cables without boots / connector sleeves like these:  http://www.amazon.com/gp/product/B00E5I7VJQ/ref=oh_aui_search_detailpage?ie=UTF8&psc=1  
Or you may have to shave a bit off the fan frame."

Something some of you might not know if you don't work with computers (others might see this as obvious but from some posts here I would say some don't)  that with the power supply you purchase comes many cables, if you want to hook up fans directly from the Power Supply you can simply use the 4 pin molex power cable to the adapter cable that usually comes with the aftermarket fans.  If you are trying to find the right speed to airflow ratio, you can simply buy a fan controller like this cheap one (powered by one 4 pin molex power connector) that will let you select the right speed vs. sound and monitor the temps with the AntMiner GUI.  http://www.amazon.com/gp/product/B00HG9AB1G/ref=oh_aui_detailpage_o09_s02?ie=UTF8&psc=1  There are more expensive fan controllers that show RPM and voltage that can control up to 6 fans if you prefer to know the RPM.  A setup might be a EVGA 1300 G2 power supply that powers 2 S5's and a 4 fan controller that can control the 2 (or 4 in a push pull setup) fans.  If you want to monitor the RPM via the AntMiner GUI, I've seen adapters that have the RPM wire to a separate connector than the power connector (usually used to the CPU cooling fan connector when powered by the Power Supply).  If you have money to burn and want to go all out, the NZXT Sentry LXE powers 5 fans and is in a made for external housing (instead of a 3.5 or 5.25 computer bay design), but doesn't seem to be available in the U.S.

i have updated my review of the S5.
it can be read here:

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

It now seems to me, evident why the S5 is an open unit.
It is my presumption that due to the string design, the S5 struggles to cool properly.

Update 01 January 2015
I have decided to downclock the S5 on account of my discomfort in the temperature of the unit. It is located away from my home in a garage and whereas in the daytime, I am able to leave the garage door open, I cannot do this at night.
The reason I am uncomfortable with the temperature is that when I checked in on the miner remotely this morning, temps had gotten to 80+ degrees - although the miner was still hashing at advertised rate, I was glad to be able to have the door opened. Tonight I have underclocked the unit to a frequency of 218.75 and it's doing ~750GH/s with temps at or around 50 degrees celcius. I do not have a meter to allow me to measure the wattage but will presume it's being quite efficient and also will stay at a sensible temperature overnight in a closed space.

updated synopsis...
Q. would i recommend this miner?
A. I would recommend this miner only if the price is relative to a hashrate of 750GH/s

ADD: I would not run this unit at stock settings in my home - there is something about those plastic sides which make me a little apprehensive and feel this the S5 is only a few degrees away from giving out flames.

ADD 2: all three of my SP20's (underclocked) were at 30degrees in and 57degrees out this morning. I have no fear about the safety of these.

ADD3: my SP31 was also perfectly fine temperature-wise and this is not an underclocked unit

[IYFTech]

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.

Hmmm.....I got back from New Years Eve celebrations earlier and noticed the same thing with mine, but all X's. They all came back after a reboot also, but it is a little worrying.....  Anyone else had this?

EDIT: Also at stock freq with temps @ 65.

Hi Gents,

What is your average ambient temperatures?
Here in South Africa we have been experiencing temperatures from 27-39 degrees C.
My S1 was running at 51-54 degrees. I read that the units should not reach 60 degrees.

My S5 is running in a 40c room. The chips are right around 60c and working perfectly. 60c seems quite cool, so I don't expect any issues at that temp. I can hold my finger on the heatsinks just fine.

My S1 worked in higher temps (south Europe) for long periods not to mention the s3 with even 35-40c summer temps all good.
Now that I see the s5 guess will be the same

not sure i would agree. The temperatures on my unit are just fine, and Im not really concerned at all with the heat of the unit. I run the fan on 5V and aim to have the board temperatures averaging around 60C. With a nearby window cracked slightly an intake of 5C allows me to overclock to 381.25MHz/1255GH without tripping my 612.5W PSU rail (fan is on a 5V rail so that frees up 12W+ for mining). With room-temperature (~20C) intake I have to operate at or slightly under the stock 350MHz.

The plastic sides would likely not deform until a minimum of 100C, and actual melting temp has to be well over 150C, or the temperature that the antminer shuts itself off or would otherwise be failing massively (which nobody has experienced yet).

keep in mind that the SP20 temperature is more air temperature than the board. Asic stats show that the chips are 85C underclocked or up to 125C in normal operation. Antminer chips go into the 75-95C range I believe, and the sensors on it are likely in contact with the hot side of the heatsink. 55-60C is an ideal temperature for the S5, above 65C may spell trouble

that said, 80C is very high, is your garage warm? I found that if you put a cover on the unit air crosses the heatsink instead of blowing out the top around the beaglebone.

  just because your atmospheric temperature is warmer it shouldn't make the ASIC any hotter. No matter what temperature is your ambient, an overheated ASIC can still ignite - and moreso if they are strung together.
