doesnt matter, i spend 20£ in electricty, in the moment dont cover me the cost i dont swicht on this monsters Grin

which pool its better discus? slush?

IIRC Discus is PPS and has a high fee.
Slush's payout algorithm is flawed which allows pool hopping and dedicated miners suffer.
BTCGuild is rock solid, with a 2% fee. However also merged mines NMC to somewhat compensate for the fee.
Eligius is always up, with glitches every so often that delay payouts and stats. But it always pays out, eventually. And is no fee. And merged mines NMC.
p2pool is reliable, however it's difficult and time consuming to get Bitmain hardware to work reliable with it. Some people have better luck than others. (I gave up trying.) Smaller pool, so blocks are less frequent, but more valuable. If you can run your own local node, you can merge mine if you think you might get a block.
ckpool is a newer pool, and smaller, with 0.9% fee. Does not merge mine. Blocks are less frequent, but more valuable. Run by the authors of cgminer.
some people like mmpool. I don't understand why. All the transaction fees go to the block winner, which is contrary to what Bitcoin stands for.

Me, I have my S4s pointing to ckpool, and my Spondoolie pointing to p2pool.

which its the average to find a block in on ckpool?

anyway with 10th you do 0.10 btc per day more or less in antpool

If that's all you're making at Antpool, it's time to ~~fine~~ find a new pool.

10% discount has been offered to Second Hand S4, 0.3465$/Gh and shipping out within a week after full payment

This is a good deal people. You cannot buy this much hashing power for this price anywhere in the world. Bitmain consistently out prices everyone. These S4's will be good to run for 10 months at least with underclocking later on. We need 50 more S4's. P.S. Thanks for the rapid PSU replacements. We had several go out right away and Yoshi took care of us fast. GO BITMAIN

No offense, but sounds like fan boy speak. How do you know they'll be profitable for 10 months?

Also remember S4s don't work well on all pools.

And they are prone to drive failures because of cheap components.

In other words, you get what you pay for.

M

Have to agree. The ONLY reason you'd want to buy an S4 at that price is if you had FREE power and a guarantee for replacement power supplies and Fan's for the next 10 months.

Hi about the fans i found a solution, run without the case.

here are pictures of my room

they are all underclocked all the units run at 137.5 and 0690 721w

anyway with 10th you do 0.10 btc per day more or less in antpool

at the current price of btc my order of 16 antminer was totally a bad idea

today mining at home an be profitable its impossible.

my experience its nobody go to sell one machine if they can do money first KNC BITMAIN all want the same Money.

Bitcoin going to suffer a big fall soon. the current difficulty and the prices go to make the people dump and dump more coins for pay the bills.

Today im swich off the rig, i start to loss money only after 6 days of activity.

Does anybody see 0.5W/GH with undervolting AntminerS4 ?

What about noise level?

I have been speaking to Yoshi about S4 issues but wanted to get an opinion here since I imagine he is not working on weekends.

One of my units is being shipped back because something burnt. It also had an issue with Fan#2 which is what I posted about earlier.

Looking at my second unit I noticed that Fan#2 in this unit only runs at 240 RPM and the others are about 4000. What caught my attention is other screenshots showing fan speeds and Asic chain temps that are close.

My temps are

chain 1 60
chain 2 48
chain 3 60
chain 4 51

Both of my units have been like this since they arrived. It seems odd to me that both units behave the same way. Anyone else having similar issues? Is there a Fan#2 issue?
BTW - temp in the hashing room is 22C.

Chain 2s for *some reason* are cooler than the rest, its likely just due to its positioning in the case, and so the corresponding fan runs slower. It is nothing to worry about,

Hello, I need some help with my S4. Sometimes when is mining the hash power shown in the LCD, for example 1989.3 GH/S, it´s not the same that the hash power in the pool. In fact the pool seem like it´s dead. So I have to turn off and turn on the S4 and problem solved but its very annoying do this 3 or 4 time per day.
What can I do? What is wrong with the S4? I have 2 weeks with it

P.S. what pool are you using? Some work better than others with the S4.

Those temps are in line. I wouldn't worry about the the fan speed unless the unit is showing extra hot temps on the LED screen. 68C is about as hot as you want to see. Anything more than that and they may slow down a bit or some chips might shut off and turn to X's. But remember, if you get X's on the chips just reboot the S4 and the chips will all be back to O's. I have never lost a chip permanently on S1's , S3's or S4's.

Hello. You need to set the minimum difficulty ON YOUR POOL ACCOUNT to 2048. Also you should update your firmware on S4 to the newest version. https://bitmaintech.com/support.htm?pid=00720140930114518599JXGHWWD80660. The file is initramfs.bin.SD-20141016.tar.gz. Log into your S4 and go to "System" then " upgrade" then flash the downloaded newest firmware image onto your S4. . Doing these two things will increase your pool hashing to almost 100% of what it shows on the LED screen on the S4.

Expensive :p Though, it could potentially underclock to get really good efficiency. I really like the S4, but it's heavy, add in the shipping.. OMG... Not at the current BTC prices.

Are you guys releasing a new firmware for S4 that will support minerlink?

Potentially, yes.

Hopefully with an improved CGminer version so we don't have to update it manually every time an S4 dies? Would be nice if Antminer's interface also supported changing queue settings for us p2pool miners.

I have now had quite a good run after a lot of headaches at first with crashing and odd behaviour at stock settings. I was scared at first to try any higher settings but eventually got the courage to give it a go. The ambient air temps of the area it lives in fluctuates between 24C and 32C. When the ambient air temp is at 32C the miner does reach 64C, but these screenshots were taken at an ambient air temp of 26C. Also I am just using the stock PSU on 240 Volts.

You should know
...about Voltage: You can set there what You want, because it has no effect and does not change real voltage of PSU. If You watched cgminer script in S4 unit You knew, that there is always set the same value 0725.
...about S4 PSU: it is 80 GOLD PLUS PSU, running at the very top of its abilities. If You overburn it (by changing voltage via ssh in cgminer script), You can damage it, and I would like to see You how are You replacing it.
...about GHs hashing power: overclocking is lowering efficiency rappidly, if You get 10% more GHs, You loose more then 10% of energy at the same time. No more words about hw errors growing volume. I do not see any sense doing that, but if You want to play, play.

I apologize if this topic has already been covered in this thread.

I was wondering if anyone has any recommendations for Replacement fans in an Antminer S4.

If you could link me to a proper replacement I would sure appreciate it.

With any sort of ambient temp, you're going to need to leave the two rear fans as default. You can replace the front two fans with two Corsair SP120s's. [Affiliate link] [Non affiliate link]
