If you are not interested go play on someone else's thread. I have done plenty of business with many people on this forum and they know who I am. This thread caters to those people.
It is perfectly logical from my perspective. I buy 15 units then sell a portion of them at a premium to ROI instantly. Then I am mining free.
Well, if you are catering to the same people you've previously traded with...all what 8 of them? Then it might be more effective for you to just message them personally about your loan request. And to be honest the forum members you've previously traded with might actually be interested in that... Once you have a physical good then you are more than welcome to sell it here. Otherwise you're just opening a channel for you to scam some unsuspecting noob. NO ESCROW NO ITEM? = SCAMAlso, please move your loan request to the appropriate channel so that you can get painted red as is appropriate. That is some asshole behauviour and false accusation as kilo17 has nothing but positive trust ratings so far. He has clearly declared what he is selling. |

Among the server power supplies, my recommandation for the Avalon 721 or 741 is HP DPS 1200 FB.
Sidehack here at the forum has them, packed with the breakout board and PCI-E cables.
In ATX PSU area EVGA is a good choice.
Bitmain APW3 is also pretty reliable choice.

Building solar power in Sahara is a BIG MONEY project. And there is several challenges to come over with, heat and sand for example. It would be cool though to see big ass solar power plant in Sahara and HVDC (high-voltage direct current) connection to power big part of the world  |

If it is strictly a question about what is the maximum hash rate miner you can get with max. 500 USD budget, then I would say the answer is a secondhand Antminer S7.
First find a reliable guy selling the S7, then find the power supply, then you know the cost and you can see the help above and try to estimate if you can make profit with the Antminer S7.

1. Find out your running costs (electricity, solar system cost etc.) for mining.
2. Select the miner, PSU and other needed components and estimate what is your ROI and possible profit based on the above by using calculators available online.
You need to take the Bitcoin difficulty rise into account.
It's pure cost logic.
Low running cost--> better profit
High running cost--> worse profit or no profit.

Well my faulty R4 is now fixed and on the way back to my place. Fedex has it in Cologne (Germany) at the moment.
No details about what was repaired though.
At least they fixed your R4. They sent back a broken R4 that would not hash. I resent it back for repair and now they said they can't replace it because they don't have any more R4 units. They want me to pay some BTC to get as a replacement a T9. It's faster but also louder. Terrible customer service. Try to get a swap without additional payment. The R4 are doomed. After a second failure of one of the hash boards (with requisite cost of sending R4 out once for repair already) I have been offered the swap of R4 for T9 if I send it back again on my dime. Yes, I already asked to have shipping back paid but to no avail. Not sure how to proceed with this... on the one hand I like the efficiency of my R4 which is unmatched. But it's very flaky and unreliable operating history is rather lame. Thoughts? If you can deal with the extra noise and extra electricity cost, I would go with the T9. |

I just can't believe that these scams keep happening over and over again, and there feels to be hard time for some people believing that this is a scam.
I'm just so tired with newbie, no background checking -people losing money and shitty scammers getting away with the scam all over again and again and again...

You are going to end up with losing money for nothing.

Is the pin order same? If not, you'll need to carefully with a small screw driver remove pins and then re-attach them to the connector in a correct order.
I have done this once for Sunon MagLev fan and it is possible with a correct tool for the job.

By the way, check out the first three posts in this thread and updates by me!I got the BB board in the mail, and the build is now ready. You better cover the sidewalls with some rectangular pieces of plastic (like on original S5s). I guess the surface of PCB on the other side of the radiator should be cooled by the fans too. Yeah thanks, this is a good suggestion and I must see how I would build it. Perhaps some sheet metal cover. This way I won't get any surprise with some part on the non-heatsink side of the board getting too hot and suddenly failing. |

Pool operator needs to be around for the pool to operate properly, but this seems to not be the case with Eligius anymore.  I use to have great time mining here, but that is in the past. |

As I understand, these rigs use a DC-DC power converter.
How well regulated does the input 12VDC need to be?
I have a high-current DC source, but it can vary from 11-18VDC (not very well regulated).
Wow, that's not very regulated source at all. You need it to be in the 11.6 - 13.0 VDC area. |

And how is this Bitcoin related?

I have a Baikal 150mh/s I'll sell for $500, which is what I paid for it. It has the latest software and runs great. These are seriously good miners. Why would I sell you ask? One word.......Vega. PM if interested.
I'll throw in the power supply for free.
What is vega? Google AMD Vega The AMD Vega GPU architecture is the next generation graphics silicon the Radeon-red team are working on for release early this year, with the flagship Radeon RX Vega promising to deliver AMD a graphics card that can finally compete with the very top-end of rival Nvidia’s GPU stack.

Hello Guys
Please help me, i need to flashing firmware to an SD card, but in the Bitmain Downloads I found the procedure to the S7.
I need to flash the S9.
Regards
Do the procedure as you would do it to the S7 but use S9 firmware files instead. I don't know your specific situation but I hope that you have gone through all the reset/restore options before doing a new clean SD card firmware image. |

Mmm.. why did you buy four power supplies but only two breakout boards? Also you would have been better with Sidehack's package of the DPS-1200 +breakout board and 6-wire 16AWG PCI-E cables like I said. I give you an advice, then you go and buy just something without any specific knowledge and ask me if it's okay, AFTER you have bought it.  Makes me wonder sometimes if giving advices is useful at all if no one is listening. |
