One S3 should run just fine even on the most weak shitty PSU. even if the PSU burns, the miner should be just fine, if the connectors are not melted. If there are melted connectors, then it's a bit different.
That's not true. On the way out a PSU won't necessarily stick to 12V as various internal things start turning to goop. you are correct but the op said he could run 3 100gh. r boxes that is about 375 watts. so I am thinking the first s-3 was a bad unit. remember he got the end of life s-3's .---------------------I base this on the assumption the op is telling the truth. If he honestly thought that an S3 had blown up his perfectly good / adequate PSU, why would he put a further THREE PSUs on that unit as each subsequently fails? I don't think we're getting the full story. |

Got my batch 4 miner yesterday and am surprised at the 0 H/W ?
Looks like an error, my unit with a week uptime also has 0. I'll report it now. Edit: actually I'll get back to you. |

to how much can the S5 be OCd ?
I tought they first said it can't be OCd at all ?
Its not guaranteed but there may be a small amount of headroom. You won't get the headroom like on previous generations as there is no voltage control. Anyone overclock on a CX750(not m)?
If your unit is overclockable, a CX750 will do it fine. |

So.. I've tried to search this, but I haven't seen anything on it. I have a new S5. It seems to run fine. Every once in awhile, though, maybe every day or two, I will see that it is running at half efficiency.. in the 500-600 GH/s rate. I go into to miner configuration and hit save and apply without changing the settings.. and it goes back to 1150-1200 GH/s. Sometimes it stays for a day or so.. sometimes it stays for an hour. Is this a faulty power supply or a firmware glitch..? Anyone else seeing this happen?
I'm seeing the same thing on my 1 S5. Frustrating. Sometimes a save and apply click in the configuration page works for a full day or two. Sometimes only a half hour.
Hoping there's a firmware fix coming to fix this. In the mean time is there any provision for a periodic reboot built in?
Yes, its a known issue and will get fixed soon TM. Current solutions are timers on the PSU to hard reboot [harsh], or software monitor's like M's to issue soft reboots on hashrate drop. Soft reboots won't always fix it depending on which exact issue you get though. |

What do you guys think  ? Hash rate is about right, looks good. |

Hey dogie so I had a big run around today after upgrading to the newest s3 firmware ugh miserable amount of HW errors, and real pain to downgrade to previous versions, finally figured it out and am currently using that 10/24 hardware which i found a link of yours to get it  once again you are awesome. But figured i would post here and ask what is the best firmware to be using 20141219 has had unanimously good feedback, and is based off the already strong 20141024 firmware but also fixes the reset button. There isn't really a reason to upgrade if everything is stable and working as it should. I don't have an S3 so I can't recommend firmwares from testing. |

Anybody know - would an S5 run properly if you plugged another fan and two more cards in to it (provided you powered the two additional cards with a sufficient PSU)?
Because the situation is that one of my two S5s came DOA - the top PCB is defective and I'm waiting for a replacement. Worth the risk of plugging the two cards on the broken miner into my working S5?
I wouldn't try it, those cables are also mightly short. By DOA, what do you mean? We can probably get it going again. |

I've got a few S4 that recently started having every single share discarded. All of them started this behavior at the exact same time.
Temps are showing as 0, and all ASICs appear to be online. Any ideas? I tried reflashing the firmware, but that hasn't appeared to help.
Running through some steps to double check: 1) I assume you've done hard restarts 2) I assume your mains power is okay and unchanged. Green lights on the back of the PSUs? 3) I assume your pool is fine (what is it)? As its at least receiving shares to discard If multiple units all had exactly the same thing at once, it can only be the 2 things external to the S4s: Internet or power. There are multiple S4 at the location. about 25% of the units at this location have this problem. The other 75% are fine. The units are not local to me. I'll have to head over there tomorrow to physically power cycle them and visually confirm LEDs. Was just wondering if there was something I could do remotely to get them going again. ssh reboot didn't help. Unfortunately no. While you're there might be worth checking some of the internal power cables as they can work their way loose [bots holding them down] via vibrations. power cycle got rid of the gremlins.. Glad to hear it. |

Every month when I get my power bill I look at cost of electricity to mine and value of bitcoins mined during the same period. When it cost more in electricity than value of BTC I'm going to shut down. I guess if enough of us do then difficulty will go down.
You are looking at it from the wrong perspective. You need to be wishing for the big players to call it a day, that way there is a chance for bitcoin difficulty reduction that is sustainable. The home miners do not account for a large enough percentage to "shut down" in concert to cause a difficulty reduction that is sustainable. Its those huge corporate farms, the same ones dumping BTC thus responsible for the downward pressure on BTC value that need to shut down. If you are signed up to a collective, pray, if not then get your witches' broom out for them! They're doing the same thing. CEX.IO has already stopped. Maybe you're right, if enough big players stop mining. They usually have an advantage with lower power cost, but we have the advantage with lower maintenance cost (since most of us do ourselves as a hobby). *Said they've stopped, its not the same thing unfortunately. |

I'd be interested to see what list level 3 creates. Potentially there could be a difference in weighting between levels 0-2 and 3?

...and another one 1/2 dies on me. This is getting tiresome, I could have just got some S3s if I wanted 500 speed. Reboot, change frequency, hard reboot, new PSU... same thing. That's two now  What PSU were you on, and what now? |

- How can we understand the best share in s4? what does the value actually mean? High is good or low?
Best share is reasonably meaningless, it just shows how close you've got to a block. High is better but its random luck. - My miner is currently set to 8194 difficulty as suggested by my node owner. Is it good or bad? whats the difference between setting diffculty to 2048 or 4096 etc? In details please or any reference to post where it is explained.
Lower difficulty = more work for the pool but less discarded shares for you. 1024 or 2048 would be most appropriate for you, but the node owner will want you to have a higher difficulty. - I see that miners with same hash rate as me in p2pool are earning higher than me but i noticed that they are in different node. How come that is possible? Might be because i have higher difficulty set? or because i am in a bad node?
Its random variance, aka luck. Last question is, how do you maximise your earnings in mining, any specific things to follow?
No Its random variance, aka luck. |

Well the timing of this couldn't have been worse!
What chip is this using that has such terrible efficiency?
Its been out for months and months and months already, this is just a video post. |

I changed ISPs yesterday, and have a new router. Antminer beeped for a while, then I changed the miners ISP to 192.168.0.99 (My PCs is 192.168.0.1)
Now the Antminer isn't minning. It seems to be working all right - green led blinkning, red led on, but when I look in the "Miner Status " tab I just get "This section contains no values yet" for all measurements.
A different thread suggested changing the settings for the pool, but don't see how I could do this.
I'm mining with Slush's pool.
Any ideas or advice gratefully received.
Thanks
First, what is you new router ip? From there you need to set the gateway & dns to your router address. Usually router use xxx.xxx.xxx.1 as ip, your pc should not use xxx.xxx.xxx.1 as ip. Or, set DHCP. It fixes 90% of problems like this. |

Hey,
got my own pair of Rockminer New R-Box'es. Both are working flawlessly, but the noise of the fan is bothering me. I found some dealers/websites who are selling New R-Box (Silent Mod) - does anybody know anything about these mods?
I have taken my R-Box apart - 70mm fans@12V connected via 2Pin JST PH Connector to the board. Do I need to replace the fans with quieter ones or is there a quicker way - e.g. resistor-mod/command mod cgminer...
Thanks in advance.
Fan resistor cables would be the easiest / quickest / most reversible / cheapest method. You'll find them everywhere (Newegg, Amazon etc). |

Past 8 days I have been hashing with my two S5 systems.
They would almost daily, at stock settings, would fail to around 600GH per system.
Temperature is 38c on the readings, 350 frequency, 850 watt Gold EVGA power supply with 4 unique rails.
At first I thought it was the firmware that needed to be updated, but after updating the firmware yesterday it seems to at least increase the chance, as now one is entirely offline and the other is hashing at 600GH.
Multiple power cycles and one of them isn't staying online for more than 1 or 2 hours, though both were hashing at 1160GH for a couple hours after a reboot.
I never recorded temperatures above 40C (It's very cold here in a large unheated building).
What should I do? Do they need to be RMA'ed? Are others having this issue? Is there a script I can run that will auto restart or power cycle them when hash rate is this low or not responding at all?
I'm ready to buy 10-20 S5's instead of a Farm of SP20, but so far the S5 is not reliable enough for a personal farm, even with just 2 compared to my SP20 farm.
Let me know what to do.
What PSUs are they on? |
|
|

The S1 and S3 had a setting in one of the config files where you could set a goal temp for the fans. Any idea where the S5 might store that setting? I figure if I can raise the goal temp a bit, I can make them a smidge quieter.
I don't, sorry. |
