I sent the user a PM inquiring about a review unit, and after further consideration, I am going to decline the opportunity for the following reasons.
- My spider sense is tingling due to the pricing being suspiciously low and it's a self moderated thread
- I have serious concerns about the product functioning to spec based off their displayed renderings. I question their ability in dissipating 4.8kW of heat in that form factor
- It is not energy efficient given the competition
- This is not a well suited system for home mining due to it's outrageous power needs
The 4.8KW power will put-off many home miners unless they have a spare 240V dryer circuit or drive and charge a Tesla Model S regularly in their garage. |

Hey there,
I am interested in reviewing your miner. I specialize in objective review of crypto miners, and have reviewed Bitmain, Spondoolies, Bitfury, Avalon gears.
Thanks.
Please send a PM with more details and your full address and name. Thank you! Sent!. |

Applied for a review unit. Lets see. Any pics of what's inside the unit?

Why this sudden spurt of interest in FGPA? Anything other than Blakecoin ?

The chip that I removed the heatsink from, on the SP20, would not reach > 0.60V until I applied epoxy glue to the glue spots and pressed it until it stuck w/o wobble.
The 2 screws do a crappy job of applying uniform pressure on the die. Air is a great thermal insulator.
Ever seen a heatsink bolted on to a large die GPU with just 2 diagonal screws?
Once the 2 screws are completely tightened you're saying there isn't enough pressure on the die? Would it be possible to add a washer to each screw between it and the top of the heatsink to increase pressure? There are spacers on the two screws which limit the amount of tigtening force to protect the die. 2 screw setup is not the most stable, since it allows for wobble. |

Tesla should really allow paying for it with Bitcoin.

I know I have posted something like this before, but this time I'm adding more descriptions, because I left out lots of details.
I want to earn 0.1BTC-0.3BTC in a month at most. I am 13 years old, so I do not have any bank account, so I can't spend any $$.
I am willing to do activities such as signature campaign and stuff.
Things to answer for me:
1. What is the highest paying signature campaign that I can participate in?
2. Any place where I can loan Bitcoin?
3. Any other ways that I can earn bitcoins FAST?
Things To Know....
I can program JavaScript, HTML, CSS, and Processing JavaScript pretty well.
I spend 10+ hours everyday on my laptop.
I'm very determined. (Willing to do almost anything.)
My address is: 15k9H74VrEVGndYrrgHoDBkzBv5CNY1ukc
and donations are very appreciated!
Offer to do programming stuff. |

I am curious, why would you reply to an issue about GMO by referencing a herbicide issue? And then you reference cancer incidence rates, which has no obvious relation either to GMO... Glyphosate /Roundup herbicide is part of the package for Monsanto Roundup-ready seeds. Roundup will kill all plants except which are Roundup ready (GMO, because of the introduction of EPSPS gene from a bacterium). btw, I have observed many consumers think GMO is a kind of hybridization / feature selection. GMO involves inserting genetic code (dna) from one organism into an unrelated organism. (e.g. DNA from bacterium into plants (eggplant) to produce foreign proteins which are usually insecticidal). Hybridization is selecting good genetic traits in the same genome, no genetic code from another organism is involved. |

Are the new AS compounds conductive? because it used to be more or less non conductive.  |

Did you put some Epoxy glue to the heatsink in order to make it stick back to the glued in portion and not be wobbly? I did not remove the copper plate from the heatsink. I only put AS5 on the cores and it did well the job for them sticking to it. AS5 is a non adhesive thermal compound, it does not have good adhesive properties. There are 2 diagonally opposite screws to tighten the heatsink, ideally there should be 4, in order to apply adequate pressure and close the thermal gap. if you are not using glue on the white spots where the heatsink was factory glued, your heatsink might not have good thermal contact with the chip. What was your hashing rate and chip voltages before repasting? My temps are fine on closed enviroment. is even better than before repaste. i was doing 80-85. Dropped to 68-69 after this, i have not glued anything, it just sits whit preasure. [/quote] |

we must have gone to different schools
Im still waiting for you to re-paste the other 7 chips on your SP20 and post the before and after results Mr Scientist
Not before you leap down that cliff and let us know the gravitation acceleration that was measured.  Some scientist you are...you should know that gravity is a constant ...want an apple to race with?  Back to topic...what were your results from before and after with your 8x as conductive as MG grease...I am very curious to know your results as you actually went through all the trouble to remove 1 whole heatsink assembly...soooo what were the results from using your super duper AS5...was it 8x cooler? any numbers at all from your clearly extensive testing to back anything up or just another lame signature spam campaign hmmmm Im done ...thanks for the laugh   Glad that you found humor in this thread. Sigs are cool, and a fact on this group I do not think I compared MG thermal stuff with AS5. All I did was remove one heatsink, took a pic, replaced the grease with AS5, screwed it back in. The voltage on the said chip did not rise immediately to the intended level of 0.65V because the thermal gap did not close. Then I applied epoxy adhesive and put pressure of the heatsink until the epoxy cured. It closed the thermal gap and the chip worked fine at 0.65V. Just like it did before the heatsink was removed. What I can say is that most likely AS5 has equal thermal conductivity compared to the OEM grease. 8X thermal conductivity does not imply that temps will be reduced by 8X. (Final temps also depends on the temperature differential between chip and heatsink). I think it means that AS5 will conduct 8X the amount of heat than MG paste. i did not remove the thermal greese from the blates between the heatsinks and the copper, i left that, as i read on some treadh that someone had a big issue whit that. The greese looks fine ,its alot and it keeps dripping when its hot , the boards were full of greese but didnt seem to have any bad effect, i still cleaned it, i just repasted the chip between the copper plate but nothing more than that, i put just a drip as it said that the AS5 is very think and it was really consistent , i had to press abit to get some good spreading on the chips  Did you put some Epoxy glue to the heatsink in order to make it stick back to the glued in portion and not be wobbly? |

science
1.
a branch of knowledge or study dealing with a body of facts or truths systematically arranged and showing the operation of general laws:
the mathematical sciences.
2.
systematic knowledge of the physical or material world gained through observation and experimentation.
3.
any of the branches of natural or physical science.
4.
systematized knowledge in general.
5.
knowledge, as of facts or principles; knowledge gained by systematic study.
6.
a particular branch of knowledge.
7.
skill, especially reflecting a precise application of facts or principles; proficiency.
I guess your science is...if you cant convince them with facts, then baffle them with bullshit? Of course PRICE and composition have no bearing on anything...lets buy 150G worth of AS5 and re-do all our miners...NOT
Science..the art of bullshit?
systematic knowledge of the physical or material world gained through observation and experimentation.
(What do you think systematic knowledge is buddy?) Have you ever heard of experimental errors; nothing that one measures is totally accurate, there is a probability associated with every scientific observation. |
