Is there a way to enable API Access on the dragonmints T1's? Ive tried via the antminer API access tab and its all failures after changing the name and password to the correct combo.

LOL, I'm not even selling it. Honestly I wish my friend would have just posted the file vs. selling, but hey, it's his choice.
Tell you what, do you have an S9? Pretty sure I've got some different size duct adapters laying around. I'll send them to you, you and Einstein test them yourselves then send them back.
Man I would love this. I got s9's t9's a3's b3's and T1's. Ill PM you now. |

Love your post. Your officially an idiot according to person 2 because you have no proof and your just trying to "sell product". |

The reason is that miners - and any other machine that uses high volume fans for cooling such as, chillers, compressors, etc are designed with the expectation that the device has free air flow in and out. ANY added restrictions will result in higher temperatures. There is near zero margin to allow for also having to push the air through ducts.
Ductwork adds resistance to the airflow. Bigger diameter = less resistance but added resistance is still present and is NOT a good thing. If you insist on using ducts you MUST use an in-line booster fan rated to pull at least the miner airflow to cancel out the added resistance to airflow.
So the argument to this is, there is no free airflow because of the hash boards inside which are in person 2's opinion the "choke point" or "area of greatest resistance" Since the diameter is the smallest at that point 4" or 6" doesn't make a difference afterwards. Person 1 says even if that is the area of greatest resistance or choke point the 3 fans (2 in the antminer, 1 exhaust fan in the box the duct is connected to) will benefit from 6" ducting. |

My opinion is you shouldnt be shrouding and ducting these machines, they were never meant to be setup like that.
If you have to, there have been many people on here that can confirm 6 inch ducts lead to much lower temps than 4 inch.
I thought so as well, but couldn't find the relevant thread or posts. Can you link me? |

It is not the shrouds that need consideration - it is the ducting they are used with. By themselves, yes a 120mm to 6" shroud will have marginally less reduction of airflow vs a 4" but I wouldn't worry about it. Connect ducting and it's a whole 'nother ballgame -- 6" or larger is a MUST.
Yes ducting is used with these, so 4" shrouds have 4" ducting, 6" would have 6". The question remains why 6" would cool a machine more if indeed the limiting factor is the machine itself. Can somebody explain with a reason please? |

Ok, so having a debate with somebody and hopefully somebody on here can answer this question with an explanation. The shrouds I am refering to are https://www.ebay.com/itm/AntMiner-S1-S3-S5-S7-S9-L3-120mm-Fan-Duct-Cooling-Shroud-to-4-Inch-Vent-Sampler/132534314729?hash=item1edba926e9:g:tjsAAOSw4qxapTmo (Thats the 4in version, 6in same thing but 6 inches in diameter.) I believe I had read on a thread here sometime that 6in ran cooler than 4in, I cant find it, if somebody does and can post it would be appreciated. Ok so the debate is, will 6in intake and exhaust make the miner run cooler than a 4in. One person says yes, bigger size more airflow. One person says no, the airflow will be the same since the limiting factor is the inside of the miner. Since the inside is the "choke point" 4 or 6 inches wont make a difference. Peoples opinions on this? Person 2 is citing Bernoulli's principle as proof that 4 or 6 wont make a difference. |

What temp is to hot for this miners? I just received my miners a few days ago and have hooked up a few. Looking for another space to put 20 or so. In the 6 I have hooked up, 1 only has 1 hash board working on default firmware, updated to the latest firmware and still only chain 1 is working. Trying to autotune to economy mode to see what happens. What do I do if this still fails? Do I try the above firmware? How do I warrenty this? Have 2 miners that boot up and hash fine on factory settings. When I try to change pools, or change the performance level. Everything goes blank and spins endlessly. No updates to front chart have to manually reboot after an hr to get screen back to normal. Also if any smart people here can answer this it would be appreciated. https://bitcointalk.org/index.php?topic=4337051.0 trying to figure out how to cool my miners best. |

Can somebody tell me with the latest firmware update what the power consumption is on all 3 modes?
Also, is there any reason to NOT run on performance mode if I'm paying a flat rate in a datacenter?
It depends on whether you're using 120 or 220/240V and what efficiency your PSU is. They're usually around 1200,1540,1640 here for 14, 16, 16.4TH at 240V with 94% titanium PSUs. I would not run them in performance mode unless 1. you had a lot of cooling (ambient at or below 20C), 2. your PSUs were rated above 1750W and 3. your electricity costs were extra low and efficiency did not matter; the Myrig PSUs are rated at 1680 which is cutting it too fine. Thanks for your response. Yeah the electric is "free" included in the flat rate for hosting so that's why I was asking. I'll be using the Psu's halong sold with the units and 240VAC. Ambient temp is way lower than 20C, each rack is vented and they have a large air system. |

Just pointed my miners at this pool and 0 would connect.

Not valid collateral.
I'm not sure the point of this post unless your trying to get your post count up. The title clearly states no collateral. So technically it's not invalid, it's nonexistant. |

Change your title to borrow, otherwise it's a false statement. Your aren't loaning 10btc your asking for it.

Great will send the collateral back at 11 am texas time as my bytom wallet is on my desktop at work ok? Yeah that's fine |

Hey guys,
I have two $100 Bitmain coupons available for donation to Kano Pool miners, just hit me with a PM.
That's the spirit, if you have any takers they can ping me for my 6 $100 tokens too. Am i right in thinking that the new s9i don't allow coupon use ? Not sure but worth checking, I've just given 1 coupon away 5 more left. When do they expire? If good for another month I'll take 2 if possible. Also I hope we get this block, fees are rising, 13.3btc is estimate for this one so far. 40 mins and nobody found it! |

The bytom wallet finally synced ill be sending bitcoin in a minute and no i will never scam anyone the wallet took a while to sync "overnight". Thanks I'll confirm when I get. |
