One of your boards is shutting off. It is probably on the edge of failure.

The numbers on a calculator are so far off you may as well scribble numbers on a wall and throw darts at it. There is no way to estimate difficulty or LTC price that far out so all those numbers are trash.


The reality is, an ASIC miner in this space as a 3 month ROI, a GPU rig will cost twice as much and have more like an 8 month ROI

70c on a card with a thermal limit of 94c is just fine, not sure what that other dude is talking about.

Whenever anyone is having strange windows behavior I like to point out that linux is 1000x more reliable and stable. You really shouldnt be mining in Windows if you want a stable, reliable rig.

If you dont trust a hosting service with your software, why would you send them any hardware?

The fans can still spin and look functional but if they are not reporting the RPM to the controller they will show up as failed.

I am talking about the daughter board inside the miner where you plug the daisy chain cables into. The hash board connect to an internal controller which is then in turn controlled by the RPi

There is no serial number saved into the device. If you want to use a number for tracking it would have to be the controller MAC address.

There is no way you can clock it to 1000 without burning up the hardware. That was a very bad decision.

Ive seen those errors. I just threw the RPi away and put another in its place.

dont mine on your laptop, you will just hasten its death

power supply problem? Thats where i would start.

Server hardware is too expensive. It will ruin your ROI and gives basically 0 features that another machine does.

If you want to be able to remotely restart crashed rigs just get something that will flip the power off and on. There are plenty of managed power receptacles that do this.

How do you know you have voltage issues? You need to describe your hardware setup, what you have done to troubleshoot, and what you are talking about with voltage issues before anyone can give you any useful suggestions.

Why would you use Windows? It is total shit for mining.

Stick with linux and save yourself hours and hours of wasted time and headaches.

I can confirm you only need 12v on the 4 pin power connectors to make this work. I have over 100 of these boards with PICOs and PCIE 6 pin to molex adapters to power the board.

You dont want to buy them.

Also you dont want to Vega for mining, they are terrible.

Why would people pay for firmware that will just damage the unit? Overclocking asics is just plain stupid. Even if they survive the machine will drop the s7 levels of efficiency. Also it sounds like none of these guys understand how the fan controls work, yet another failure point. Also, $15 per unit for firmware? fuck you.

Your board temps are fine, as long as they stay under 100c you have nothing to worry about.

Unless you have older S9s you cant reduce the frequency anymore. Yes they would output less heat. Think of an antminer as a space heater. It is 1400w by default so its a 1400w space heater. If you can knock the power down to 1000w, its  a 1000w space heater etc.

The hashing board is dead, and there really arent any parts serviceable by someone not adept at board level repair.

The only solution is to send your board out for repair. It is normal to have blades randomly die on older s9s.
