There is nothing in the miner that would be emitting formaldehyde.

On the other hand, cigarettes contain formaldehyde and there are tens of millions of idiots still smoking.


Verdict: FUD

1. Ethereum is not synonymous with the entire gpu mining ecosystem, it is just one of hundreds of coins.

2. ETH devs cant even get PoS working on their test net. You *might* see it by 2019 at this rate, but even then its just a hybrid system that is 10% PoS and 90% PoW still.

3. ETH, ZEC, and many other GPU algos are asic resistant. They are specifically built to not work with ASICs, and devs have come out saying they will change the algo if someone does figure out how to make an ASIC so its not even a concern.

4. ASICs can mine a single algo, but not a single coin. Theres a good dozen coins a sha256 miner can mine.

5. Dont invest any money into mining that you cannot afford to lose. Mining takes a large investment to properly get started. You shouldnt be mining and exchanging all of your coins, you should be mining and hodling as much crypto as possible. This is not a short month to month profit game, this is a long term slow play kind of thing if you want to make any real money.

Running linux will fix all those weird issues.

Nahh just blow through with your compressor and make sure you dont spin the fans while you are doing it. No need to disassemble for cleaning. In fact, I would not pull things apart ever if the machine is working properly. You for sure dont want to be messing with the heat sinks like that. They are bonded to the chip directly with thermal epoxy, you bang one the wrong way and it rips the top of the chip off and you have an expensive paperweight.

Nothing extreme about it, this is mining functioning as intended. Go take a look at how much the network speed has increased in the last 45 days.

What does any of this have to do with bitcoin mining?

How exactly is blowing some air into the AIR intake going to void the warranty?

Most people dont think the sky is falling after 3-4 days of price drops and pull the plug on entire datacenters. You realize how many machines would have to be switched off to make a dent in the global rate right?

There is a button for 'code' that you can use to wrap that all in a text box and not spam the forum itself with mile long posts. This will help you post the full log without making a post thats 2 miles long.

You are using a site that autoconverts to bitcoin. Bitcoin price is in a total minute by minute free fall.

This is why you shouldnt mine to any of these autoconversion sites. Be less lazy, mine a good altcoin, then profit when its price goes up. If you want bitcoin, buy a bitcoin miner.

No. You cannot find them at 'normal' prices. If there were vendors out there selling at MSRP nobody would be able to sell them for more.

Because that 80c limit was for the s7. The S9 runs up to 105c, you for sure dont want it to stop hashing at 80c. When the miner hits its actual thermal shutoff temp it will show all chips with xxxx in the status and you have to manually restart it to get it mining again.

No because you dont want to run a PSU at 100% load all the time, that will cause an early death. Just like with breakers, I de-rate my PSUs 20%. I wouldnt push a 900w psu 24/7 over say 700-750w max.

I have an idea.

CALM THE HELL DOWN.

Website errors and issues happen all the time for a variety of reasons. Jumping directly to a scam accusation on the largest hardware manufacturer in the space is pretty ridiculous. They arent going to waste time scamming you and your single D3, use a little common sense.

You should be running linux to mine, mining on windows is asking for headaches.

Have you tried taking off all cards but the troubled one to make sure it can still hash on its own?

Have you tested all the individual components? (riser, cables, PCIE slot, etc)

I just re-read this and realized you made the mistake of buying from a reseller. As you have seen multiple people have confirmed delivery so im betting you just bought from an unethical seller. he is either mining on them before shipping or he oversold his preorders and is just gonna screw people.

You are talking about third party software and not the built in bitmain firmware which is what I was talking about.....

The control boards may say s5+ but they are for the s7. the early model 54 chip boards had the controller with 6 fan plugs and 9 IO ports. The later models removed most of those parts for what I assume is cost savings.

The 45 chip boards run at a stock freq of 700 to achieve 4.7TH. If you run them at 575 will should only see around 3.8TH.

The 54 chip boards default frequency was 575 to get to the expected 4.7TH because it physically had more chips then later models.

The side with the taller heatsinks is directly connected to the hashing chip. The smaller heatsinks on the backside pull heat through the board so they wont be quite as hot as the other side. You still need to cool both sides equally tho.

I am not sure what you are talking about with bmminer. There is no temperature throttling built into the antminers. They hit overheat temperature and just shut off.
