How about:
6a) Which manufacturer pays legendary members who are known to be positive towards their company, to commission and adjudicate polls that are biased towards their company, because they were unhappy with another user's ranking, and then tries to hide that they're actually the company paying for and commissioning them?
6b) Which manufacturer used a preorder model? [can't do this one on the forums, should really be doing this on survey monkey anyway]
Dogie, you're more childish than my grandchildren together. Get one time to understand, you represent today greedy and disgusting company, who sells his old used miners . Who cares about your opinion, we all know who pay you. |

I have 2 EVGA 1300 G2  I will be ok with both of them. Do you know if it's possible to power some blades with a power supply and some others with another if a single controller drive all the boards? Not yet tried. But looking at this picture, why not? |

Next question: Which manufacturer is located closest to Israel?
.....
I ask instead, what manufacturer miners burn out a higher flame and may ignite a fire ? |

Tupsu, you stated that water blocks need to be attached to the bottom plate that you drilled holes in, but is this really necessary? Isn't the 4 screws on the front frame (behind where the fan is attached) enough to support it? The back would be supported by the tube connecting the two water blocks together.
I have built water blocks in C1 housing . There are four mounting holes on the bottom for water blocks and four mounting holes in front and rear. Screws are very short, so I used all the screw holes. Because Syscooling has not yet been posted my S5 Modified Kit , I made today another C1 double housing for my ordered 3 x S5. S3 housing construction with 2 water blocks is one possibility, but I prefer the C1 case and even better S5 Modified Kit from Syscooling. |

My water-cooled S5 with selected miner blades works.with EVGA G2 1300
1295W 2580GH/s 0.502W/GHs
I have to try a more powerful power supply unit.
What frequency are you running that thing at? Also, I cannot see you having more than 2 blades, but I may be wrong, how many blades are those? 2580GH/s .... ? Care to post a screenshot of the webUI? frequency 400 2630 GH/s 1375W Silwerstone 1500W PSU with soldered EVGA double cables ( SST-ST1500 )  |

....
The S5 won't get 1.3TH/s at 650W though, unless your unit is significantly better than mine are.

This is not true. If power is limited, buy more SP20
1x SP20 1000GH/s 0.45W/GHs Can the S5 do this? No.
What you never want to ROI? Seems to me unless you have expensive power SP20 should be ran hard (1.4-1.6TH) to make up for the initial investment. I think the beauty of the S5 is its pretty much the SAME efficiency @ 1.1 or 1.3TH. So run a S5 @ 1.3TH with 650W then compare that to 950W required to get an SP20 to say 1.4TH give or take. The SP20 can be downclocked to be more efficient sure but I have both the S5 and SP20 and at this point I'm more impressed with the S5. Simply because I see that roughly 0.5GH/W efficiency @ 1.3TH, which maximizes my return without losing 25-30% of the hashrate just to meet some arbitrary W/GH goal (which varies greatly depending on location overhead and power costs so YMMV of course, to each their own). I won this SP20 miner. https://bitcointalk.org/index.php?topic=789369.0cost me only 40USD VAT, so I can use him to efficacy tests |

You are using the bulk 15 unit price by SPT. I'm sure if you PM Bitmain, they will come up with a discount bulk price for 30 units the same way they come up with a bulk price for 52 units AND offer free shipping or discounted shipping. So, just because SPT has a quoted bulk price FOR 15 UNITS does not mean Bitmain will not do a bulk price for 15 or even 30 units.
See what I'm saying?
I do agree with you for the under clocking of the SP20 to the same efficiency as the S5. However, do not assume Bitmain will not give a discount on shipping or no shipping costs for 30 units. That's all I'm saying. Just because SPT actually lists their bulk price with shipping costs ($0.00) for 15 units does not mean Bitmain would do similar with 15 or 30 units.

If limited to 18,000 watts, one can obtain more hashing power with the S5 versus the SP20.
One single SP20 @ $479.00 without shipping [1,700 GH/s @ 1200 watts = .705 watts per GH]
One single S5 @ $370.00 without shipping [1,155 GH/s @ 590 watts = .510 watts per GH]
Let's say power limitations at your location is 18,000 watts:
18,000 watts / 1,200 watts = 15 SP20's x 1,700 GH/s = 25,500 GH/s (25.5 TH/s)
18,000 watts / 590 watts = 30 S5's x 1,155 GH/s = 34,650 GH/s (34.65 TH/s)
Without going any further with comparisons on ROI, one can easily conclude the S5 is easier to achieve ROI than an SP20. This is based off the price of one single unit. If one wishes to compare based on bulk pricing, they must use both bulk package prices [SPT's 15 x SP20's versus BITMAIN's 52 x S5's]. Even if one wishes to choose the bulk price of 15 x SP20's versus the price of one S5, it would still be more worth while to get the S5 at this point in time. The main reason why it would be worth it IS TO KEEP FROM LIMITING THE AMOUNT OF HASHING POWER I CAN HAVE WITH THE LIMITED AMOUNT OF WATTS AVAILABLE TO MINE.
If limited to 18,000 watts you will have approximately 36% more hashing power with the S5.
Just saying...
This is not true. If power is limited, buy more SP20 1x SP20 1000GH/s 0.45W/GHs Can the S5 do this? No. I am happy that I bought 2015-01-26 at night three S5 for 3.983 BTC ( Today it costs 4.894 BTC) But I bought later on the same day 3x SP20 for 3.954 BTC , and it was a much better deal. 1 BTC=303USD 3x SP20 3 TH/s 0.45W/GHs total 1350W 3 x S5 3,45TH/s 0.51WGH/s total 1750 W 450GH/s more costs me every hour extra 400W nearly 300 kw / 30EUR per month, But only produces 0.0122 x 0.45x 30=0.165 BTC per month |

Can I power 8 boards with 3 power supply (1300W + 1300W + 850W)?
Idealy each 1300W can power 3 boards and the 850W can power 2 boards.
4 boads works perfectly with EVGA 1300 G2 (1300W)  |

Do not forget , S5 is fire hazard. |

Are You sure that everybody wants to read You many off-topic hate messages about water cooled miners and what You are going to do with You coins?
Got my batch 4 S5 miners today and they are NOISY only one can scream over 5 undervolted and underclocked S1s and 2 std S1s which I have in house. Totally impossible to use air cooled S5s in house and 2 S5s are enought to heat my garage.
So much air going throught S5 that they are going to fill up with dust and garbage very soon if they not used in clean room like electronics manufacturing or very clean server room.
With big water radiator and slow fans I can avoid blocking the miners.
4 x Antminer S5 with shipping is today 1667.691 USD Water-cooled kit will be cheaper. $1598,48 |

Can I buy only 8 boards, 2 controllers and necessary 8+2 cables?
If yes, then I'm interested.
I am not sure,later I will tell you. That's ok,confirmed. for 8 boards, 2 controllers and necessary 8+2 cables + shipping ? |

We provide S5 water-cooled modify kits,you could look at this thread https://bitcointalk.org/index.php?topic=929437.0 Also,we provide water-cooled S5 sale.Each water-cooled S5 have 4 waterblocks,8 hash boards,it is equivalent to 4 air-cooled S5's. The price of each water-cooled S5 is $1307,...... i want one, but im curious how much is the shipping? and do the watercooled kit contain everything except PSU?
Not exactly, shipping cost is about $130.This is watercooling kit http://shop.syscooling.com/goods.php?id=45$1307 is the price of whole water-cooled S5,doesn't include watercooling kits.To cool down a water-cooled S5,I suggest you to use two SC-BC1 watercooling kits http://shop.syscooling.com/goods.php?id=45 ,with each radiator installed 6 fans. One full set miner price is $1307 miner $100 2 x ANT BC1 mining cooling kit $130 shipping = $1537 +4% Poundage = $1598,48  |

Interested in 1 and 1 sc-bc2 kit. But before I would to have an idea of the noise level. Is it 2 fans like in the C1? How fast are they running?
Yes. 2 fans. You can replace them with 2x Silverstone SST-FHP141 |
|
|
|
Are there any recommended fan replacements from the default ones?? The C1 is a little nosier than they said it would be.
Silverstone SST-FHP141 |

vote with your money - don't buy until they reduce it back.
btw maybe someone will make SP20 groupbuy?
I just did that and bought 3xSP20 Order 4400 Cheaper than 3x Antminer S5 3.954 BTC versus 4.169 BTC |
|
|
|
... Is the SP20 better built? Better firmware? ..
Yes and yes. |
