Shit I had to have another 20 amp breaker installed here to handle 1 S4. I would have to have a new service ran if I had 6 of them!!!  Come on now, 120v is for peasants! :p Run your hardware on 240v. An S4 is only ~5.7A on 240V. |

Ah, that explains the low quality pic.
Dust will still be an issue with water cooling, you'll just clog up your radiator. If you can't prevent the dust from entering the building or the miner with filters, your only solution is cleaning them out regularly.

what would be a good fan replacment? I dont really care about noice  I assume if you can get the chips cooler they will hash more and also more stable right? Not really, no. Lower temp might contribute to having less "x" chips, but probably not unless you're close to 80c. If you don't care about noise, get some high power Delta fans. Noice isnt my problem, dust it is! 3 fans are death after 3 weeks only, see pic. I am looking for some fan that can handle dust. sealed bearing maybe? Higher rpm?  Damn, that's a lot of dust. If I were you I'd open it up and blow it out with compressed air (from a compressor, not a can) every month. Delta fans are pretty much the best quality fans out there, if anything will deal with the dust it will be them. How old is that camera? LOL |

Your fans won't go above 3K if your temps aren't high enough. If you're getting 1.5TH, you likely have a dead hashboard. Look to see if one of the board's red LED is off.

I'd take the w/o PSU unit if you ship to Canada, and depending on shipping costs.

Where are you shipping from? Escrow accepted? How much per SP20? Are they SP20 or SP20"E"?

I use Nicehash (Europe version) and have never had a problem. I just set up a worker just for Nicehash with a min diff of 128 to get the ball rolling. It currently at 33334 diff at 30TH. Runs 24/7. Should be jumping to 50TH soon. Are you using the bot?
Ah, that was the problem -- Westhash is for pools on this (U.S.) side of the pond :-) I switched to nicehash.com and slush seems to be working much better! No bot, yet. I'm still in training ... :-) Thanks! -dave Ahh darn it. I spoke too soon. The nicehash order was auto-canceled too, after about a half an hour, saying "Action" Cancelled - placeholder order" with a link to their FAQ: Why was my order canceled (placeholders)? https://www.nicehash.com/?p=faq#faqb13Ah well, back to CKPool I guess thanks, -dave Might want to ask in the nicehash thread, not sure if the dev keeps up with all the pool threads. |

Thanks for the image. Not free, but pretty cheap at about 0.07c USD. I'd have to figure out if it would be worth it to run them overvolted, and for how long. |

Someone please help me understand the concept of the "difficulty" setting.
So far, I get that I have 3 - s3's on antpool with a recommend difficulty setting of 512K.
Next week, when my S4 comes in, I set the difficulty for that 2THS/S machine at something bigger because it is more powerful. I forget where this is set right now, but I know it is a setting.
Would a S5's be set somewhere in between an S3 and S4?
Does this mean that the S4 is more efficient because it can take on bigger chunks of work?
Is work or shares dolled out according to the level of difficulty?
Does the higher dificulty level of a faster machine like the 2TH/s S4 mean that the machine will remain profitable to operate further in the future?
So far, I've read two "beginners" level books but they do not explain this. This is keeping me awake at 3:45 AM local time so please help put my mind to rest so I can go to bed!
Thanks,
Tom
If your mining on Antpool, then just go to sleep because the difficulty is set by the pool software with what's called a dynamic diff. You have absolutely NO CONTROL over what it TELLS your hardware is the minimum acceptable share difficulty. I understand but is a S4 better than 4-S3's (if S3' ran at 500MH/S)? Is the S4 going to produce more/faster/better hashing at the end of the day because of the level of difficulty it can take on? I am also assuming that power is the same. No, the 2TH/s of S3s will produce the same payout as 2TH/s of 1 S4. |

Hi!
thanks ))

Congrats! How long did you have them pointed here before finding the block? |

Why is bitmain still pretending to run a p2pool server?  BITMAIN announces Antpool: Pushing forward Decentralization
We support p2pool protocol
The p2pool protocol prevents hashing power being controlled by one central entity (the pool owner), and has been significantly developed during the development of Antpool. All p2pool code will be open sourced and uploaded on BITMAIN’s Github link in the near future https://github.com/bitmaintech/p2pool. (We hope open source it in one week but don't blame us if it delays a little bit.) we hope that we can optimize the p2p protocol and network with other interested engineers around the world.
We believe p2pool protocol has great potential, however, it is not developed very well till now.
Firstly, p2pool protocol's total hash rate is low compared with the whole network's, which is around only 2% of it as of Nov 2014. So p2pool's output is still not quite stable. There is a network effect barrier we need to break, then the p2pool protocol will have stable output and more miners will join the protocol. One of the most import reason for this is that there is not a well developed p2pool agent mining pool. If there is a well developed agent as the p2p.antpool.com, the total hashrate of p2pool will be significantly increased.
Secondly, the protocol of p2pool network is already optimized a lot, but for average miners, it is not as efficient as it could be, especially for some low bandwidth miners, whom will not be affected if they are connected to a normal solo mining pool. We hope our efforts will help the community feel easier to set up p2pool mining nodes running with high efficiency.
If p2pool protocol can provide a more stable output, and the code is published, we hope that there will be more and more independent p2pool mining nodes around the world. There are lots of enterprise level miners around the world. I think it will be in the best interest for themselves to run their own p2pool mining nodes, if we can develop it into a convenient, reliable and efficient tools.

I rented some hash power at WestHash tonight (just a little bit: 100TH :-) and pointed the order at Slush's pool tonight and it got auto-canceled after about 15 minutes. The "Pool verificator" said Slush's pool was compatible, but right after the order started the order status page kept saying something like "pool connection problems, pool diff too low, minimum difficulty is 127" which is a problem, since i have the worker configured for 1024 difficulty pool-side. Then it started hashing and managed to get up to about 30TH before the order suddenly got auto-canceled. it refunded the charges, which is good at least. I was able to do this last week on CKPool (kano.is)... Is slush's pool known to work with westhash rented rigs? Is it incompatible? From this it looks like it should be supported: Which mining pools are supported? https://www.westhash.com/index.jsp?p=faq#faqb2thanks in advance for any insight, tips or tricks! -dave Not sure if this was issue, but with 100TH you should set a starting difficulty of about 71000. 1024 is way too low, though vardiff should have kicked it up fairly quickly. |

Searing,
Are you generally drunk or high when you post? Genuinely curious, no offense intended.
LOL. Honestly I thought about asking that question also in the past when reading his posts. I assumed that English wasn't his primarily language. I did too, but I'm pretty sure I remember him saying he was in the US in one of his posts so I figured I'd ask.  |

if a spondoolies miner is stolen - can the serial number be used to track it down?
 Did someone break into your place? |

Like other S4 owners, one of my PSUs blew shortly after the 90 day warranty. Bitmain's response? "find one from your local market".
It's astounding that Bitmain will only give a 90 day warranty on their PSU.
I was pretty sure I wouldn't be buying anymore Bitmain hardware. This sealed the decision.
M
Sorry to hear that. The warranty should definitely be extended on the PSU considering it's horrible MTBF. That's what I said to them. Just about every namebrand PSU manufacturer offers a minimum of a 3 year warranty. If Bitmain is only offering 90 days, that essentially means they are using junk PSUs in their unit. BUYER BEWARE. M Definitely leads one to believe they have no faith in the quality of their PSU. |

I own a metal fab shop, would anyone be interested in either galvanized, aluminum or stainless covers for their S5s? Cardboard is a really bad idea.
I'd be interested, what kind of price do you think ballpark? Not sure, I need to get my hands on the dimensions. I'd likely use galvanized to keep the price as low as possible. Looks like I'd need to knock out 6 holes per capping with the water jet, 4 PCI-e and 2 data ribbons. I might try to get my hands on a dead or cheap S5 locally to get proper measurements. It would be 4 holes for the pci-e, and 8 holes for the screws since I imagine you would use the same mounting location. The ribbons would not need to be outside the cover. Ah OK, thouhgt I'd need holes for the ribbons. Good to know. I really need to get my hand on an S5. I own a metal fab shop, would anyone be interested in either galvanized, aluminum or stainless covers for their S5s? Cardboard is a really bad idea.
So, you'd be capable of fabricating water cooled sinks for S3's and S5's? Yes, shouldn't be a problem. I've also had someone request a full S5 case, ala S3. Going to look into that too when I find an S5. |
