same thing here, not rackmountable, very annoying..
I'm going to find some flat headed screws tomorrow and take care of that, it doesn't need much in the way of clearance. Will let you know what I source. |

I do find it funny the same things are being said in this thread that people were saying on the release of the SP20 and on the release of the S5, that the new chip is on its way, that you'll never ROI etc.
Bitcoin is a gamble. Everything about difficulty is based on current price vs difficulty. If the difficulty doubles and the price remains static, welp, current gen miners will be impossible to generate a profit from unless you're stealing electricity. If difficulty doubles but BTC price goes up with it or we go back to the moon, who knows then?
If you like bitcoin as a technology, think of it as taking a shot. It might pay off, it might not.
Unless you've got a good amount of money to invest in finding a space with solid power and cooling in one of the very cheap kw/h locations, its not going to recoup its cost most likely.
I do consider it a higher reward with higher risk. I would not say gamble though. As you can do it with a educated gess on a lot. Difficultly has slowed down which makes it nice for miners. It's harder to do but with decent electricity it can be done. I think its an educated gamble. I bought 8 sp20s in December and they've been mining 24/7 since then. I'm fortunate enough to have a rack where I'm paying very little per kw/h so my sp20s have ROI'd at this point, anything past this is gravy, but the story could have been way different. BTC could have dropped to 80 dollars or the .14 and .16nm fabs could have ramped up instead of had huge setbacks and I'd have thrown 5 grand in the toilet. I think at this point we won't see 'next gen' miners until late q4 of this year at the earliest, so there's a good chance my s5s will ROI before any huge changes happen. With the heat in india/china driving mining down, people who can continue through the summer have a chance to do a little better for the next 3 months. |

Two issues with my new s4+ so far:
1) Mining on westhash has locked the box up twice within two hours of mining. Moving it to kano.is or btcguild.com, no lockups.
2) The screws that come with the s4+ are too big to allow you to mount it in a 19" rack. Really? I spend 1000 bucks for something I can't even rack mount because its got the wrong screws?
The screw thing is beyond annoying :p
Nicehash does not use a regular stratum server. I don't think smit has made a unofficial firmware for S4+ for it but I cold be wrong. The other pools dont require the patch so they run better then nicehash does. Yeah, I don't mind really, I can just on one of the bigger pools until/if smit does an s4+ firmware.  |

no worries bro, i only get pissy at ppl who bring attitude, trying to convince me im lying, stupid or doing it wrong.
Everything you've said is well thought out.
pool details & watts used on the kill-a-watt (now running at 12xx & 724watts, which i assume is all 4 hashing) - if i recall correctly, each chip is set at 165w
i havent tried accessing via another com, but i shall - before i post this. (done - see below)
but the sp30 is running fine and accessible, so im not sure what gives with the sp20
i did notice that when its set to use dhcp - it constantly wanted to use the same IP as my laptops (no idea why)
but i set it to .33 so it 'should' be there, advanced IP scanner shows it as there, but no joy with browser or putty.
OK - tested on other laptop, FF & Chrome - nothing - comes up with a blank screen with just the IP in the address bar.
im going to leave it alone as its doing the important stuff - fk a gui for now, maybe itll turn up
bless you for your time & consideration, its very much appreciated!
Grab advanced IP scanner and do a network scan. If the miner is online and hashing, it has to be active on your network. It would really be odd if the ssh daemon wasn't running for you. I've had my SP20s from time to time boot and mine without the http daemon start up, but not with the current released firmware. |

hello
it is possible to change the clock automatically?
i will love have my ant working at 300mhz between 08:00AM to 23:00PM and 400mhz or more between 23:00PM to 08:00AM
I don't know that something like that is possible on the antminers. Works great on my SP20s tho.  |

Has anyone used NiceHashe's custom firmware for the S5s? I know it runs a newer version of cgminer that the latest Bitmain one. Wonder if there are any advantages/GUI updates with the nicehash one.
Also what they typical HW error rate or these? Im getting .1% on one and .003% on the other. Even though they are both really low one still produces almost a 1000x extra hardware errors.
I run the Nicehash FW with Westhash for both my S3 and S5 and the result is clearly superior -- I presume it's due to extranonce support! Whats your reject rate? Im constantly getting around 5% for both my S5s, and im running the Bitmain 4.8 CGminer version that has extranonce support. (just at NiceHash BTW rejects on other pools is < 1%). Using Smit's, my reject rate was around 1% on average. It'd spike from time to time, but setting right back down to below 1%. |

Went to check speeds tonight, saw this on one of the miners:
Rebooting doesn't change it, what are the troubleshooting steps to take from here?
1) The loss of the temp sensor suggests it may be do with either power into the board (all), or its cables to the controller. 2) But the lack of mining on the other suggests the controller 3) Put it on its own PSU, so the Evga 1300 temporarily. 4) Put it on BTCGuild for now. 5) Try swapping ports the board connects to on the controller 6) Then try swapping a cable from a known working miner and see if the problem moves. 7) PM me your order number so I can check warranty status please. That should be enough for now. Thanks Dogie, I'll try those things tomorrow. |

I haven't been able to mine for a few weeks, I was traveling when my datacenter went offline. I've got 6 S5s back online, but one of them appears dead suddenly today |

I run it on 6 of mine, overall it works great, you get good speeds and you get access to graphs that smit put in place. whats speeds are you getting per s5? Depends on the pool. Kano.is gives me the most consistent speeds, always 1120 - 1180 nicehash it varies wildly, but seems to average out around 1030 over 6 miners. Not a huge sample, but still ok. |

6 Antminer S5s all running slow on nicehash/westhash and randomly locking up about one a week, sp20s run full speed... any ideas?
I'm running the updated firmware with extranonce enabled from Smit1237, but all 6 of my s5 miners run between 950 and 1050gh/s vs running near 1200gh/s when running on kano.is or a couple of other pools. I've had 4 lockups in the last 5 weeks as well, box is just offline. Cycling power fixes the offline issue.
4 of them are powered via an IBM 2880W PSU with j4bberwock's breakout board, the other two are powered by an EVGA 1300, so power shouldn't be an issue. There's plenty of overhead on the 2880 and some overhead on the EVGA.
Any ideas on how to get them to run at proper speeds on westhash.com?
what does westhash report your speed at? i noticed while on westhash my speed is under what it should be as avg, but westhash sometimes reports my speed faster.. sometimes as high as 1300 GHS. i think its just low diff coins.. i get like 10 blocks a day mining on westhash, the coins cant be that high of difficulty. I don't know what speed they report because they're all mixed in with my other miners. I'll set up a wallet just for the S5s, that would be interesting to see what speed they're reporting at. you dont have to do that, just put .worker after each one and they will be listed separately. I just use my bitcoin address as my username, I don't have actual workers set up. I didn't see a way to set up normal workers with nicehash, maybe I missed something. You can also use custom naming for your miners when using one BTC address for multiple miners. Simply append .name to your username: YOUR_BITCOIN_ADDRESS.name where "name" can be any string with up to seven alphanumeric (Aa-Zz, 0-9) characters (if more then seven characters or if non-alphanumerical character will be used, naming wont work). https://www.nicehash.com/?p=faq#faqs1Oh, that's awesome, thanks, that'll make it easier to identify them. |

Hey guys, xposting this from the Antminer S5 thread:

Are you running at default speeds or are you overclocking? This might also be an networking issue, please try connecting to EU stratum server for test: stratum+tcp://sha256.eu.nicehash.com:3334#xnsub Everything is default, I can try .eu, but since I'm on the west coast of the US, I'm going to get some wicked latency. I don't really mind the slightly lower speeds(granted, I'd prefer to not have them), but the lockups are what's bothering me. |
