Sleeve bearings are shit
not true, good quality sleeve bearings can last years but cheap sleeve bearings doesn't last long. Cooler Master fans have quality sleeve bearings. Sleeve is shit compared to ball, fluid, mag, etc. The only advantage sleeve bearings have over other more durable bearings is cost. But those cooler master fans aren't cheap. |

Want a 200-400W miner ?Get a S7 from ebay or amazon ... remove 2 hashing boards from left and right side , leave the one in the middle ... get a 750-800W 80 PLUS Certified power supply if you want to run just one hashing board ... keep the 2 hashing board as a spare or sell it on ebay as a parts for S7 .. set the fan to 45% or less , but watch the board temp and adjust the fan speed as need it , try to keep the temp around 60-65 ... and you good to go  you have a 400-450W miner with 1.5TH/s hashing power . If you want less power usage you can always under clock your miner  You can get a used S7 under 600$ , im sure the price is going down in the future as we are closer to the halving event in July ... You can sale each hashing board around 150$ right now.. so from 300$ you have a 400W miner + have to spend some money on a PSU ... +1, best way to get a 400W miner. |

Why?
There are better ways to throw away your money.

ETH is in the "return to normal" stage of its bubble. The profit calculations won't look as pretty at the bottom.

There is no market for home whiners. Make a S7+ instead.

Make a miner that is better and cheaper than Bimain's 16nm would be my request  |
|
|
|
Interesting thread. Any questions? When will we see a 16nm Avalon miner? What is the target $/GH and W/GH? |

I would have to agree with OgNasty on the release date due to this msg:

Solder the wires directly onto the board and continue mining.

What a crap article, so much typos. Anyways, i guess this just prove competing with China's cheap labor, parts and manufacture is a hard thing to do.
power costs killed them more then anything else they never could self mine to off set costs It was also the machines to though. Compare the SP20 and S5 that went head to head. SP20 was metal all the way around they really did not keep material cost down. Then look at S5 they managed to use 2 slabs of plastic and keep cost's down. So there really was a big difference on materials. Bitmain just out designed them on a miner to sell to masses. And SP claimed they lost money trying to compete on price with S5 (we cannot be sure if true). But I do agree on power to if they would have self mined at less power costs... they might have been able to stay around much longer. "Bitmain just out designed them"  Really??? You mean, Bitmain beat them by cutting corners and lowering the price. Design-wise Spondoolies SP20 was miles ahead of Bitmain S5. SP20 is an elegant piece of hardware, S5 is a junk in comparison. Bitmain just does NOT know how to DESIGN anything, they know how to CUT CORNERS for more PROFIT. Bitmain Sux. I'm just so appalled by these pro-Bitmain people on the forum, do they get paid by Bitmain? If not, they must be smoking something. Did I tell you how crappy Bitmain S5/S7 miners are? They sux. Bitmain suxed all the way to the bank  |
