I run a G3930 in mine and it causes no issues. It seems like the simple fix is to not leave a thumb drive plugged in, then you dont have to worry about it not rebooting properly.

Dont use tarps. Use foam board insulation to build your hot isle. Tarps have no structural rigidity and will just make a mess of things.

Considering the unreliability of mining hardware this is not a good idea. You have zero warranty this way and are probably paying a significant markup on the actual unit cost.

Whoever wrote that article has no clue about anything crypto im guessing.

As an FYI, the only current generation miner with open telnet is the Avalon (well its rpi image). Telnet is immediately disabled when you put a password on the GUI.

You do realize you are wrong and the sata connector spec is 4.5 amps or 54 watts while a molex is 5 amps or 60 watts. They are basically interchangable and both work just fine to power risers. When people are melting stuff ti is 100% their fault for improper setup to begin with.

Also...real world mining tests I have done by using an actual DC amp clamp and some maths.

RX470 pulls 29 watts from the PCIe riser while mining ETH.
RX480 pulls 31 watts from the PCIe riser while mining ETH.
GTX1060 pulls 29 watts from the PCIe riser while mining ETH.
GTX1070 pulls 34 watts from the PCIe riser while mining ETH.

All WELL within sata or molex spec. Just because the theoretical maximum they can pull is 75 watts, in real world tests they do not even come CLOSE.

The only problem with that post is that it is wrong. There is no danger as long as you dont overload a single string of connectors by putting too many on. There is nothing wrong with the molex or sata power connectors, they all work just fine. Also I have done actual amp clamp testing and an rx470 undervolted and setup for mining pulls under 30 watts from the powered riser....hell an overclocked 1070 only pulls about 35 watts. The sata power plugs are rated up to 4.5amp (or 54 watts) so you are only putting an 80% load on the connector itself. As long as you dont try to run a bunch of risers off of one string of plugs coming out of the PSU you wont have any problems

Ill never understand why people ask if they should plug stuff in. If the connector is there, it is there for a reason. Is it really that hard to just plug it in?

I mean you dont NEED a seat belt to drive a car....but its probably a good idea to use it right?

bah I actually linked the wrong version of the correct PSU.

The cointerra is a PET1300-12-054NA

The exact same PSU but 12v. I still have a few floating around here.

You must have missed the point of the sarcasm dripping from every post in this thread. There is no 7nm speculation. It is so far away from being a reality there is no point in even discussing it.

I am 100% positive that breakout board is the internal board from a Cointerra Terraminer 4 version 2.0. (2.0 were not release to the public)

My tech team wired that up and sold it to customers. Whoever you bought that from got it from me originally.

This is the PSU that connects to the boards:

Sounds like he hacked together that system. The system should have either 3 boards with 45 chip boards or 3 boards with 54 chip boards

I like that you jumped right to 7nm and ignored the 10nm process when the mining companies are still on 14/16nm. This thread might be useful around 2020....

Thats actually not a great deal at $98/th

Ethereum requires a card with 3gb of RAM or more. If you want to mine ETH you need at least a GTX 960 or so bare minimum

The GTX 260 is OLD. Honestly its not worth trying to mine on it for anything more than a laugh. I think you might be confusing it with a GTX 1060 as a cheaper card that is good to mine on. Nobody is mining on a card as old as that 260.

You are either in some strange country you havent mentioned with laws like no other or you just dont understand how taxes work.

That and im pretty sure you will get shut off right away doing any mining on amazon hardware.

A firmware flash only affects the controller. You have a bad hash board. These are string design and it only takes one failure point to kill an entire board. If you purchased it new from bitmain in May you are still under warranty. You can put a ticket in and ship it to the los angeles depot for repair.

The claim that bitmain firmware updates kill machines is an old wives tale. People flash the wrong firmware then blame bitmain for it. I have literally flashed over 10000 bitmain devices and never bricked a single controller.

While nothing is impossible, this is highly highly highly improbable. Any reason you would want to take on a project like this that will take months to do versus just buying a nice new miner?
