I believe 2 of my pumps are starting to fail. They are making a kind of a rubbing sound and I don't think they are pushing the coolant through as much as they should, hence the higher temps. If I have to buy cooling parts all the time for this miner, I'll never break even. It is very unfortunate that the miners seem to be doing just fine, but all the cooling packages are failing or having troubles. It is quite frustrating! I'd love to buy all EK pumps, but spending $100 on each pump just doesn't make sense since the whole miner cost a little over $300.
There is a video someone posted earlier from syscooling. You might try it and see if cleaning around the motor helps. If you have one of the early pumps that was dry tested, it's possible it's plastic rubbing. I would try it on one to see if it helps. I don't want you to do both and go through trouble on both if you get no results from it. |

thanks. Did it include fittings or you had to buy those separately? It included fittings. They were nothing special. I don't think it came with the clamps used in original kit to help hold tubing though. (Could be wrong as it's been months but I believe the ebay pump didn't) |

You can ship by sea minimum one pallet and not less, even then you can have problems to find transportation company
As working with a logistics company once I can say most don't want to mess with little loads with a one time customer. They will charge per space taken up (Weight also factors in). The companies that do can save you some as they get bulk discounts. But you have to be worth their time setting up a new client. One small miner box is not worth it for them. If you were ordering bulk i could see saving money scheduling this. But I honestly think you are best off with going with shipping from a mining company. I don't see you beating them on buying one miner. That will cost more than UPS ?
You will have trouble beating the standard companies unless ordering in bulk and shipping in bulk. The only option i see as far as reducing with 1 unit is if you use a hosting company in a cheaper place to ship to. But that loses your "free" electricity. |

Aim: This is just to see whats out there and any better ways to do it,
1a> What do you think is the best site for buying Bitcoin online and offline too?
Coinbase assuming you set it up in advance to needing it.
1b> What are the advantages /disadvantages or each?
Disadvantage they require knowing who you are due to laws. Some people don't like this and use localbitcoins because of this.
1c> Any unusual ways?
If its "unusual" i would stay away. Go with well known ways.
Background
Answered above. |

I predict not making a C2. Just hard to compete with price of S5 and air cooling. I hope I'm wrong as i love a variety of miners.

This makes me want to start my on drone store accepting BTC...
Please do, it angers me too with all the scammers around. Really tempting, I will have to look into the matter and see if I can do it cost effective  On cost effective i suggest the X5 - http://www.amazon.com/Syma-Channel-2-4GHz-Explorers-Copter/dp/B00K5Y22VG/ref=sr_1_5?ie=UTF8&qid=1420601400&sr=8-5&keywords=x5They make a regular model and a camera model for a little higher. 50-60 dollars and it is a heck of drone for the money. I have played with it inside and out. Even in heavy wind it slowly made its way through the air just harder to control. For not spending much it is a whole lot of fun especially if you get the camera model. |

I can't login to one C1 and ssh is not responding. I think, I can try to reflash the sd card. How can I do that? I downloaded the firmware already.
THANKS!
Win32DiskImager will let you take it and copy image to sd card. Works great for it. Thank you I will be ok for this time. I was power cycling the wrong machine. I was like, one machine is not working and another one is rebooting by itself. But that was me power cycling the wrong machine to repair the other one... What a moron. You will be a champ at this then  . In being serious though it's a nice controller with the SD card. Allows you to easily fix software problems. I really like the design of the controller. |

Do you have to sign in to use the university internet? (Even if you had to just sign once when first setting up pc) If there is a login to use internet this could be a reason for somethings. I have a feeling this could possibly be part of problem.
Dogies idea of proxy should allow you to mine through your PC's connection that is working.
I surely can confirm this is not the case , I'm having I direct connection with no signing page . I'm surfing using the router connection to my labtop as well >
what could be the solution ??
it has to be related to the router because I need to move with my labtop a lot >
Proxy is best solution if you cannot get direct connection. Does your university have a IT group you can call? (I know alot of university's have students and some staff to help with things such as internet). You could ask them about blocking ports, etc and try to solve it. |

Let's see if I can't help you... still waiting on my C1's but been mining for long.
First of all, I figure you changed from Static to DCHP, well, the miner needs an antenna if you go DHCP (WiFi)
Secondly, to access the computer, you need be on the same subnet as the miner.
Manually change your computer's IP to 192.168.1.199 (Yes, .1.199)
You should now be able to access your miner's interface.
However you still need to directly connect to the miner itself to change its settings... you will need an ethernet cable and a router/switch.
Sometimes you can connect directly to the miner sometimes you can't, via ethernet cable... (I never use DHCP)
If it don't work directly or with a router though, you will need a switch... you may need to even change your router's IP address since some routers use 192.168.1.1 as default address which often conflicts with a mining network.
Personally, I cannot connect directly to my miners and have no idea why but works through a switch or router.
If you go buy a switch make sure you get a big enough one you can grow into with GigaBit (10/100/1000) ethernet. (No pun intended)
I got a 24 port Rosewill, has a 5 year warranty and costs around $100, tough and does its job perfectly and then some.
I just got a tp-link router . I connected the miner to it and yes , I'm now able to access to the miner page . but the problem still unsolved : the miner doesn't mine . I'm sure it's connected to the internet . Is there any special configuration for the pools ?? I'm not really sure if my connection goes through a 80 port . any advice ?? screenshots http://postimg.org/image/ej19vprbj/http://postimg.org/image/hh2u35ocv/http://postimg.org/image/x00a09wnj/That is more than just internet or other soft problems. You need to reflash the SD card using the image in the #2 post of this thread. Remove the case, download SD card imager and use it to flash the image here. I just found out that my ISP filters all of the ports exept 5 ports 3333 and 80 are not among them . can I mine to 3389 port or I need to use SSH tunnel or VPN service ?? can I set my router to route connections to that ssh ?? You might check into your router settings. (Possibly modem depending on connection). I know my ISP had all kinds of blocking with it's default settings. I was able to talk my ISP into making my cable modem into a pass-through mode where my router is in charge of firewall now. I reimage the SD card and guess what <<< nothing change , miner status is showing no data at all  , I don't think I have a lot of options because I'm using a university internet . I don't think I can talk to my ISP . which one you suggest to me : 1- buy a vpn plan 5 usd . (I haven't try rerouting before ) 2- buy a internet plan 20 usd . (not sure if isp close ports or no) Do you have to sign in to use the university internet? (Even if you had to just sign once when first setting up pc) If there is a login to use internet this could be a reason for somethings. I have a feeling this could possibly be part of problem.

So if I would of just waited a few days before ordering I would of saved $405. basically a whole month of ROI
That is almost always true in this game, at any time, with any product. In fact, products go from coveted to worthless in a blink of an eye. With product usable lifetimes so short, who wants to pay the extra cost for an over-engineered product ? If "over-engineered" means it "just works", count me in. M ''Just Works" is useful. But if it means a metal case instead of a plastic case, I say save the money. Anything that can be done design wise to reduce the manufacturing cost of a product with an expected useful lifetime of less than a year is worth doing. Personally I like metal case. I will gladly pay the difference between good gear and low quality. Sure you could do no case, no temp sensors, etc. At that point your more at prisma level. I think SP gear is quality gear I think they will continue the trend. |

We might just hit 15 percent... ouch
Bitcoin Difficulty: 40,640,955,017
Estimated Next Difficulty: 46,521,397,337 (+14.47%)
Adjust time: After 901 Blocks, About 5.5 days
But if you look at past weeks it's been a while since one so ugly last over 10:
Sep 25 2014 34,661,425,924 16.20% 248,116,151 GH/s
And last around 10:
Nov 05 2014 39,603,666,252 10.05% 283,494,086 GH/s
So quite a few good months hopefully it is just one week of this we will see if past repeats itself.

Looks decent enough, what type of games do you plan to play on it?
If you're planning on playing the Far Cry/Crysis/Witcher series type games, you may want to up the Video card to get the best possible experience, otherwise these specs should handle most gaming at above average settings.
Though I don't have enough time to sit and play games for hours, but yeah I would like change my present PC with this sort of specs soon. But yeahh, I want a good and powerful graphics in it. Anyways, isn't the R9 270X a good card ?? I have seen like many sellers selling their R9 270x's here on the forum. Card for mining is not necessarily mean it's good for gaming. The 270 is a good card for less electricity being used. But you can get quite a bit more powerful depending on what games and settings. |

I would agree depending on game and settings might want to relook at card choice depending on budget. You might check ebay aswell. If you can get a card that includes purchase proof from when it was originally bought and still has warranty, you might be able to get a good deal. |

Nicely done! Another beautiful guide.

How can you go beyond 275M? I'm pretty sure you need to edit /config/cgminer.conf. How do you restart the miner from the command line?
175MHz @ 0.650V : 356W =0.51W/GH
250MHz @ 0.720V : 650W =0.65W/GH
250MHz @ 0.760V : 662W =0.66W/GH
275MHz @ 0.760V : 809W =0.74W/GH
275MHz @ 0.800V : 900W =0.82W/GH
300MHz @ 0.815V : 1052W =0.88W/GH
EDIT: I just saw 2 asics marqued with x after 2 hours at 275M@760 on a miner. I will leave them at stock setting.
That far out I would make sure to have a cold ambient. I have not spoke about 2 batch ones for a while. I can say after getting water cooling parts sorted out these machines do run really stable(Note Bitmain was always helpful and pointed me in right directions). I thought it would be a interesting experiment to do a water cooling miner is what sold me on them. I have been lucky to have a cold winter ambient which keeps them in low temps. It is common to see this miner go into days (if not weeks) on uptime. So long story short the batch ones are running good and will continue to hash away. |

If you want to see what pools have gotten one in last hour https://blockchain.info/ is pretty accurate as far as pools that want to be known. |
