File System Version   Fri Nov 17 17:37:49 CST 2017  <---if the firmware is from 1117 aka November 17th it has issues.


You stated that you flashed your machines with a different version of the auto tune firmware, so I am not quite sure how fixed frequency comes into play there.

Also the later auto tune models wont work properly with the fixed firmware, you really shouldnt be using the wrong firmware for your machines.

When working with electronics like this a multimeter is one of the most important tools in your kit. You can pick up a cheap one for under $20 and ti woudl enable you to test many things including PSU functionality.

I have noticed a bunch of serious problems with the 1117 firmware that came loaded on all of my nov/dec/jan machines. Our standard fix is to roll the firmware back to one from last April.

This has repaired literally hundreds of s9s that would not hash or would report fan errors with the 1117 firmware.

That is pretty strange. I would bet a simple reboot fixes it.

replacing them should be ok.

One thing to note, you are driving that 900w psu pretty hard. Each hashing board pulls 425-450 watts which is driving that PSU at 100% or more.

There is a button when you post with a # sign that lets you encapsulate code for posting.

The errors you referenced both relate to the beagle bone portion of the controller. You really should post the kernel log to be sure.



P.S. The missing kernel log is actually kind of normal for the s7, ive seen it thousands of times.

Yea but you are paying miningpoolhub to do that for you so you are losing out on profits. I warn any miner away from any of these auto conversion sites. If you are auto converting to a single coin like ETH, you are leaving a crazy amount of future profit on the table.

Stay far away from nicehash.

Its what lazy people use because they dont want to maximize profits. Plus its been hacked recently and every customer lost money with them.

I have 8000 cards running off of sata risers. They work just fine, the problem is people dont understand how electricity works. You cant run 3-4 risers off of a single sata chain, you are trying to draw hundreds of watts over a single 18 AWG strand of wire. If you set shit up properly, you wont have problems. Anyone that says they have burned up a bunch of wires, dont trust what they say because they are doing it wrong.

Religion feeds ignorance and hate. It was created to control the masses but as a race we are past the need for that. Until religion is eradicated humanities growth will remain stunted.

You should try the altcoin section, that is where you mine with video cards. This is the bitcoin section and you will find no help here.

If you want to do profit switching on the local side it will be a lot of work. You would have to configure wallets and settings for each individual algo.

The bottom line is that profit siwtching is a misnomer, and it will cost you to lose money in the long run. If you are chasing minute by minute profit you wont be able to turn coins into fiat fast enough to capitalize on it. The smart move is to mine a coin you feel confident in, and hold it for future gains.

If you are cashing out your mining revenue immediately you are making a really boneheaded mistake and costing yourself so much in the long run. This is not a short day by day profit game, you need to mine coins and hold them for as long as possible or you are just wasting your time and effort.

You cant backup the running firmware, all you can do is backup the running settings. What makes you think you have a successful backup of the T9+ firmware?

Im guessing you are screwed until there is a publicly available T9+ firmware out.

whoops i misread one of the links I guess.

Why are you mining ETH on an Nvidia card?

/facepalm

DO not mine on your laptop. They are not made for sustained 100% usage and you WILL burn it up

right now the best GPU to mine with is the one you can buy for close to its MSRP.

4gb cards will be useful well into the future, the reality is you will eventually have to replace the card to keep up with efficiency/hash rates before the 4gb limit is ever reached.

There are a few people doing boards repairs on the site but im assuming they would focus on the s9 family of miners. I just cant imagine a huge market for old generation tech that cant even break even on residential power prices.

Another interesting thing to note is these are 54 chip boards. The S7 hasnt been 54 chip since batch 3 or 4. They spent the majority of the time making the 45 chip model, so something has to be different.
