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

[alienesb]

I have 20 S5 running since one week.
ALL of them freqently (within 12-24 hours) get "lost.
I cannot acces them through webinterface and not trhough putty.
They are mining (all lights show normal operation and they are hot), but NOT at my pools. No hashrate there.
I have restart them by pulling power, then they work again normal for a few hours.
Running different firmwares, happens with all of them. None of the other miners (S2s, S3s) is doing this.
Makes me think if i bought 20 pieces of crap or if somebody guilt in a backdoor to have them mining for somebody else frequently.

I cant watch the miners 24 hours a day and then drive over to trhe place to pull power twice a day.

No answer from bitmain.

Anybody with similar problems or a solution?

Try a different pool. This used to happen to me with Nicehash.

Router and everything is definetly not the problem.
IP adresses work 100% and other miners than S5 have no issues at all.

Nicehash might be an option, i will switch 10 to another pool and see if it changes.
Any idea why nicehash crashes them?

Nope but when I moved mine to f2pool they were up for weeks instead of rebooting them daily.

Isn't this because of the lack of "extranonce" support? (dunno, just throwing the idea up there)

Strange, my s5 working with nicehash for weeks and no problem at all.
About control board: try reflashing firmware without save settings. Sometimes that helps get rid of problems

I've heard this before but all I can say is that for me Nicehash doesn't work even with new firmware.

I have been on Nicehash for 24 hours and have had to reboot twice. I think the low difficulty of mining shitcoins sends an AntMiner into a circle jerk on the Interwebs. Am I right here?

That's because nicehash sucks you could not pay me to mine on that site !!!!

[Digitalmocking]

could some of you guys put the price and roi estimated of this relation ships of this ant miner s4 and s5 it seems it takes like 8 months to roi and the watts my god sorry my mining skills are not that big

you will never ROI the S4+ or S5 unless you have other miners to help. unless you have completely free energy.. then it will take like 215+ days.


at this point it is best to buy BTC and hold it.

Because maths:

At free electricity, flat difficulty, a price of 230/coin, 100% average pool efficiency and no pool fees:
It takes 118 days to ROI an S5  (ETA .369BTC/month @1150GH/sec)
It takes 153 days to ROI and S4+ (ETA. .82BTC/month @2570GH/sec)

At .10 USD per kw/h, flat difficulty, a price of 230/coin, 100% average pool efficiency and no pool fees:
S5: Cost to run: $43.00, earning $85.00 = ~$42/month in earnings, taking roughly 9 months to break even.
S4+: Cost to run: $108.00 earning $188 = ~$80/month in earnings, taking roughly 12 months to break even.

The only real value the S4+ has over the S5 is that you don't need to spend money on a PSU/cables, but I feel the price that Bitmain is asking is way outside of reasonable for that hardware.

What are you talking about?  Nicehash's average payout over the last month is 102% after fees and you get paid for all shares you submit every 6 hours.  
Currently my 18TH/sec is earning around 130% of expected norm and has been for a couple of days now.

I can't see why you wouldn't mine on Nicehash full time to be honest.

I'm using Smit's firmware on 6 S5+ boxes and haven't had to reboot once, and they are averaging 1.13TH/sec over the last 3 days mining on westhash.

[Digitalmocking]

I see the S4 + is out not a bad price  wondering if well see a

ANTMINER S5+ with improved cooling and  maybe at 1.8 or 2 th maybe ,,, hoping hoping. at about the Same S5 price   ? .




 Idc what power it uses at this point i have to start using a 240 line to many miners on my 110 lines time to start using the 240 line , i had put in  . .

The price on the s4+ is pretty awful.

i think you are right.. last night i got 18 blocks and my s5 was hashing at only 600ghs, one board was completely shut off..

i guess you need to set a monitor up so it reboots when the hash speed gets low.

Yep and it is not the same rig every time When I am on Antpool they hum along. Nicehash has been paying a bit better for a couple of days but you have to watch your miners a lot closer.

Yuck shithash !!!!

I make more on antpool and f2pool than that crap site to many HW errors for me. Like I said you cant pay me to mine there.

[montyfd]

Running 10 S5 on f2pool now and no reboot needed so far. The others on nicehash keep crashing, seems really pool related.
Nicehash was working great for all S3 for months, never had an issue. Only the S5 have problems.

Isn't a hardware error just that?  How is a hardware error pool related?

[montyfd]

For me the opposite. nicehash gibes nearly no errors, discusfish gives as many hw errors as accepted shares.
Something is not right here.

I'm running 6 S5s on kano main and extranonce with p=0125 on westhash and I've only had one issue in the last month, all 6 s5s were about 100g/h less than they usually were after a series of rapid switches over a day, I rebooted them and moved my p= amount up a bit to stop switching.

I'm running smit's firmware with cgminer 4.9.0

um no you dont..
f2pool pays out 0.01014056 BTC / Thash/s  
MINUS 4%. which is 0.0097349376 BTC / Thash/s..

way less then nicehash/westhash has been paying for the last 30 days.
