Agree 100% with MrTeal.
Scythe/Nidec seem to be pretty close to published specs, I've had some good luck with those.
However, and this is a bit caveat.
No "quiet" fan, even an undervolted Delta is going to allow you to run at max speed on a SP20
To get to 1.6+TH you need 180+CFM and air moving at that speed needs a certain type of fan and both the fan and the movement of air produce a shitload of noise.
The target for me has been much quieter than the stock fan @40-50% at circa 1.4TH which is perfectly doable with something like a 130CFM Scythe

The only way I would buy one of those would be if I could go see it working before I handed over my bitcoins.

Genesis-Mining, can you clarify the fine print clause at the bottom of the terms? *if, on any day, Coins generated on one day do not suffice to pay item 2 of the Fee above, the Service Provider may use Coins generated on any day thereafter for such payment.
Would it not be better to just terminate the contract if that happens, or suspend it or something? |

So for me, to buy say the equivalent of a SP35 and host it myself vs cloud mining it
SP35: $2235 + $150 shipping = $2385
5TH Cloud: $2232 + $2230 (5000 * 0.446/gh) upfront maintance fee = $4462
The difference is substantial and thats if you pay it up front.
The "daily charge" of $0.0015/GH works out to $7.5/day or $228/month for 5TH
Just have to compare that to the hosting fees you pay. For me its too close. Cloud mining should be much cheaper than hosted because of economies of scale.
On a final note, I'm not bashing Genesis mining, I think they are, truly one of the real cloud mining providers with real hardware and hashrate to back up their business model, also having Guy and Spondoolies vouch for them goes a long way in my book, its just that for now, for me, cloud mining isn't the solution. But I'll keep an eye out.
Biffa, thx for your calculation. I think it is very important for everybody to crunch the numbers and feel comfortable. Unfortunately I cannot follow you on this line: 5TH Cloud: $2232 + $2230 (5000 * 0.446/gh) upfront maintance fee = $4462 Can you please elaborate where the 2232 USD are coming from? Much appreciated. MS Fair enough if I read it wrong, the contract looks like it says that the "fee" is either a) or b) So I was, apparently incorrectly, assuming that the fee was either $0.446/GH up front on top of the initial cost of the hashrate OR, $0.0015/GH per day. I thought you were offering a one of maintenance fee in perpetuity of $0.446/GH  But now seeing others analysis of it it seems that you are saying the initial TH price is based on the $0.446/GH and then there is a the daily charge. I'll edit my post. So its pretty simple, if it costs you more than $230 a month to have your SP35 co-located, or more than $230 a month in electricty to run your 5TH of SP20's then this is a good deal. If it costs you less than the maintenance charge to run your 5TH at home or in a colo, then its not a good deal |

technical one: The simplest way to underclock it is by setting limit to ASIC voltage. Don't touch the PSU watt limitation. why? hard facts not to throttle a certain loop by psu limit in settings? It's possible, but it is more difficult to match "start voltage" to "max wattage". It can cause scenarios in which the top wattage is less then the initial wattage, which can confuse the scaling algorithms. So we should set psu max wattage to 288 and use the max voltage to manage the power usage of the units? Obviously start voltage should be less than max voltage, but otherwise shoudl we use max voltage as our tool (as long as its more than start voltage)? Yes, I always do that like that for under-clocking - but when I need different settings for PSU domains I have no choice but to use max PSU wattage. By different PSU domains you mean like where the asics furthest from the fans are hotter you might want to drop the watts on those? |

Can anyone tell me if there's a difference between the SP20 and the SP20E?
About 100GH at the same settings in my experience. SP20E runs cooler and faster. |

Seems the link is hard coded. So for those who don't want to sign up before seeing the contract, here is the current (as of today) version: Mining Capacity Share Agreement
sha256
MINING CAPACITY SHARE AGREEMENT
I (the "Customer") agree with the following terms and conditions for the provision of mining services (the "Agreement") made as of today
between :
Genesis Mining LTD, 3rd Floor, Par La Ville Place, 14 Par-la-Ville Road, Hamilton HM 08, Bermuda, ("Service Provider"); and
me, the Customer.
Pursuant to the terms of this Agreement, the Service Provider will make available to the Customer shares in the mining capacity of the Service Provider.
1. Services
The Service Provider agrees to provide to the Customer with the output of its mining capacity (the "Services") subject to the following terms:
Available Technology: SHA-256 Hashing
Term: The contract has no fixed and predetermined end date.
Mining Power: 1 TH/s
Payout frequency: daily
Mining Output ("Coins"): as agreed between Service Provider and Costumer, and, where applicable converted from time to time, e.g., Bitcoin or other electronic currencies
The Customer will be solely liable for the maintenance of the relevant technical equipment (software/hardware) that is required to receive the above service. The Customer will receive Coins mined in accordance with the above Mining Power and of applicable Fees as per 2.b. The Customer also acknowledges that the above Services will be rendered on a best effort basis (bestes Bemühen). The availability of the Mining Power and, accordingly, the output of Coins may vary up to a maximum of 5%. Otherwise, the Service Provider ensures that it maintains all facilities and the relevant supplies in good working order, in order to avoid any of the above volatility with the diligence that it applies in its own dealings (diligencia quam in suis).
2. Remuneration
As a consideration for the Services the Customer agrees to pay to the Service Provider an amount of (the "Fee"):
a. 0.446 USD per GH/s upfront
b. USD 0.0015 per GH/s and day, deducted on a daily basis* from the generated Coins
3. Limitation of Liability
Without detriment to the Service Providers obligation to render the Services on a best effort basis, only, any liability of the Service Provider hereunder and or in connection with this Agreement shall be limited to willful misconduct (Vorsatz) and gross negligence (grobe Fahrlässigkeit). Further, the Service Provider shall not be liable for any damages incurred by the Customer as a result of force majeur which shall include any disruption or breakdown of a Coin market.
4. Term
This Agreement is entered into for the term indicated above.
The Service Provider may terminate this Agreement with immediate effect if the Coins generated in the preceding 20 days do not suffice to pay the Fee under 2.b above.
Otherwise, this Agreement may only be terminated by either party for good cause (aus wichtigem Grund).
In the event of a termination for good cause by the Customer, and, for the avoidance of doubt in any such event, the Customer shall be entitled to a repayment of item 2.a above in the proportion of the time lapsed since the beginning of the Term divided by the Term.
In case the Service Provider voluntarily agrees to refund the Customer, a processing fee of USD 10 will be deducted.
5. Communication
All communication between the Service Provider and the Customer shall be made in writing which includes e-mail and other electronic messaging services (Textform).
6. Data Protection
The Customer agrees to the processing of its personal data provided in the context of this Agreement for the purpose described herein and also agrees, until revocation at any time to the storage of its data beyond the above Term. Should the Service Provider be required to obtain any further data in the context of providing its services hereunder, the Customer will without undue delay provide the relevant data so required by the Service Provider
7. Representations and Warranties
The Customer represents and warrants to the Service Provider that he is familiar with mining, crypto currencies and Bitcoin in particular and that he understands the nature and uses of mining crypto currencies and Bitcoin.
The Customer further represents and warrants that he will be the beneficial owner of the Coins.
8. Credit Card Services through Credit Card Service Provider
The following provisions under this section 8 only apply to the extent the Services are paid by credit card:
The Service Provider uses third party services and such third party’s affiliates services which enable the Customer to place monetary deposits and perform transfer of payments within the website of the Service Provider by making use of the Customers existing credit card (as and if available and applicable) (the “Credit Card Services” and the “Credit Card Service Provider”). The Credit Card Services do not include any additional service, and such Credit Card Services do not Customers account.
The Service Provider may share and transfer (including cross border transfer) personal information with the Credit Card Service Provider for the purpose of rendering the Credit Card Services which will be made to Service Providers website via the use of the Customers credit card. The personal information will be shared with the Credit Card Service Provider after the Customer elects to execute such monetary payments by using the Credit Card Services of the Credit Card Service Provider. For the purpose of this section 8 personal information shall include information that identifies or may identify the Customer including the information submitted by the Customer through the registration form when you subscribe to the website such as the Customers E-mail address, country and city and/or information provided through social websites or any other identifying information provided by the Customer while using the Services of the Service Providers website.
In addition, the Service Provider may transfer any non-personal information provided by the Customer through the Customers use of the Services on the Service Providers website to the Credit Card Service Provider in order to allow the Credit Card Service Provider to perform preliminary examinations of non-personal information for the purpose of determining if the Customer is qualified to use the Credit Card Services of such Credit Card Service Provider (including the history of the Customers transactions on the website which will be provided without any identifying information and solely for the purpose examinations of the Credit Card Service Provider).

I checked for hashrate purchases up to 5TH and the rate was the same, so no sliding scale of charges that I can see |

A very simple question about genesis . what is the maintenance fee?
I went to the site and it said look at the contract.
That is a problem since I can't find a contract.
As it appears I must sign up to see a contract.
The price is 469 for 1 th now if maintenance fee is 0 a month for 1 th growth is 0 plus freeze btc at 225 I break even in 182 days
------------------------------------------------------------- 20 ----------------------------------------------------------------------------------237 days
_________________________________________40____________________________________ ___________________342 days
____
So I won't argue about diff change or network growth I won't argue price of coin. I used 0% growth and froze coin at 225
but they need to show m-fee clear and they need to do it now. They need to show contracts without a signup.
It is 4:45 am I may have missed the fees , but I would like to see the fees.
Once you start the buy process you have to agree the contract which stipulates: 2. Remuneration As a consideration for the Services the Customer agrees to pay to the Service Provider an amount of (the "Fee"): a. 0.446 USD per GH/s upfront b. USD 0.0015 per GH/s and day, deducted on a daily basis* from the generated Coins Full contract link here: https://www.genesis-mining.com/upgrade-hashpower/universal/summary#contract-sha256For me, one of the major things (apart from the fees) is the pool, unless I can choose the pool, or at the very least Genesis discloses the pool(s) they are currently mining on its a no deal. |

Well I paid 800$ for my Monarches. Actually I paid 3.6 BTC for 4x but that was back in the 1000$ glory days...
I guess the Spoondoolies would be an alternative if:
1) They had customizable speed without going through their interface, which is hosted by them, they take the site down and your spoonies are turned into crap (potentially?) if they are hardcoded in firmware to connect to "the cloud".
2) If they had USB. I need to connect to my 4g router with antenna in the attic, and the house is 200 years old so: no drilling (because it would be rude) = wifi.
I could add photos but they are just monarches with fans replaced with variable speed Nonctua connected to Corsair AX760/860 PSUs.
What I think you (and all other non heating miners) don't appreciate is: monarches have liquid cooling. If you compare the GH/db with Spoondolies they are worth the extra dough, easy!
1. It isn't the "interface" is on the machine itself not hosted by them 2. It has USB and supports Wifi (experimental at the moment), or you could use a cheap lan to wifi converter |

Anybody knows what kind of fan Sp20 has? 38mmX120X120mm or something else? I can look up myself, of course, but don't want to stop the hashing.
Thinking of putting either delta or Scythe ultra kaze in place of the stock fan; i know someone even put gentle typhoon, but i need to support just 1200gh/600-650w.
>snip image< I've used a Scythe ultra kaze but they are only 130CFM which is fine if you are underclocking. Any of the Scythe high CFM fans will work, the black high speed GT's or the even scythe kaze jyuni 1900rpm But yes its a 38x120mm fan but you can use a 25mm fan if you want. I've currently got the Ultra Kaze on one of my SP20's However as its a propietary connector to the daughterboard in the SP20, you either have to cut the connector off the stock fan and wire it up to the new one, or you have to connect it to the PSU directly like I did: >snip image< Thanks. Did it help? I am not sure what % of the sound (72db at fan 20 for the stock fan) is caused by the fan itself and how much is caused by moving the air through the metallic grille/sieve. The stock fan is supposed to be just 61dB, but SP20 produces way more than that (up to 72dB close by). Yes it helped, the fan itself or rather the bearings are what make the metallic noise the stock fan makes. A kaze ultra at 100% is much more bearable. |

Did anybody tried to run SP30 more energy efficiently? If yes, care to share the settings and what the energy consumption/hashing speed will result?
I have my units in hosting, so cannot play with settings as easily as with SP20 at home.
I tried a quick test and I used start voltage .60 and set the max PSUs to 750W and it worked just fine. Can't remember stats because as I said it was just a quick test. Maybe I will have more spare time in week-end. I will go over requests next week. I recomend using voltage only (set start and max to same values or give 5 millivolt between them) till you get the performance you want. If you set too low system will not start. Keep the psu wattage as is since it will never be reached if you set max volts low enough. Whats new in 2.6.1 zvi? |

Just received a couple of Gentle Typhoon AP-31 (5400RPM) for testing, this is a high-air-flow fan for 120x25 size, it performs almost identical to Delta AFC1212DE at 20% speed
I've got the 4250rpm version on my SP20 for a few weeks now. Also tried the Scythe Kaze Ultra, which works quite well, but is also hard to find. Also from the same range the scythe kaze jyuni 1900rpm I've also tried, at 110CFM None let you run at the same temps as the stock fan, all are significantly quieter even at full speed. With a slight underclock they are fine. |

Let us know what you want to see in Spondoolies-Tech's firmware… We are open to suggestions! What do you want to see implemented in our next firmware releases? We want to hear from you
Others have made some good suggestions, I have a simple request ... that a miner doesn't forget it's timezone. Too many of my miners from SP10/30/20 randomly revert back to the year 2000 after a restart. It's a hit and miss affair to get them to time warp to 2015. I've seen others make comments about this, no idea why it happens, but when it does it screws the graphs up. Thanks for asking. It happens if the miner can't reach the pool.ntp.org server to set its time. I'd like more manual control, I don't want my miner to talk to an outside NTP Server if I have my own on the network. I want to turn SSH off unless I need to use it etc. Back to time maybe even be able to manuallys set the time from the GUI |

We want to hear from you, although we cannot make any promises to implement any suggestion, we will try out best to make it work. Post suggestions here in the thread…
*We will try our best*
A GUI option to enable/disable API would be amazing. GUI switches to turn off SSH would also be a good thing, plus for advanced users some sort of iptables in the OS for security. |
