Your post is confusing. Where are you getting those insane prices for the hardware?

Also, you can take the D3 out of the question as the profitability of them is so bad people are jumping off buildings in China after buying them.

You can easily answer this question yourself by doing 5 minutes of research into the cost and profitability of each miner.

You just need to use a lil elbow grease getting the breakout board on the first time, they are very stiff. Also, all of those plugs on the breakouts boards come from a common rail in the power supply. You can mix and match them to your hearts content and they will work just fine.

Bitmain is no longer making T9s. If you are going to buy a miner from them it is an S9. There is no sense throwing money away with a USB miner.

This silly idea that bitmain is going to mine on your used hardware just needs to go away. They have literally tens of thousands of miners of theirs that arent even being put online, so why would they bother mining with your one single RMA unit?

You sound like you have no clue what you are talking about. If your machines are creating enough heat to set a wood frame on fire then you have already melted your hardware your hardware. Also, pretty sure no one with enough equipment to require a full rack is going to just be moving shit around all the time. The best part is how you complain about society getting more stupid when you are the one saying the stupid shit.

Tao I run literally hundreds of your motherboards. They are one of the best 'gaming' boards I have found for mining. Only difference I run linux on mine. Windows is dogshit for mining. Driver problems, stability problems, etc with windows that all go away with a good linux install.

Thats because if you read the manual you will see the the MSI boards share ports.

E.g. if you have an m.2 in the second m.2 slot PCIE3 will stop working. If you have a card in PCIE port 5 port 1 might stop working.


NEVER EVER buy an MSI board for mining.

Except it doesnt and it isnt. For the most part nicehash is for the lazy and/or uneducated people that dont want to deal with managing multiple wallets or having a clue when the best time to sell is. Sure there are some times when it overpays on specific algos but that requires monitoring and switching around of pools all the time.

Thats a pretty old board and I would guess its bios is not setup for multiple GPUs. If you want to mine you should really think of going with more modern hardware. You can build an entire rig mobo/ram/cpu/hdd for like $200 if you look around a bit.

There is a reason there are two plugs. Dont be stupid or lazy and not use them. There is no excuse.

I bought in at under $9 a coin...im fine with its rise to current pricing....

There are reviews of every type of miner available on this site. Take 10 minutes and read up on them.

Every single person would shut that miner right back off when their phone battery died in an hour.

Its a terrible idea.

I think a lot of people dont quite understand that while these large chip using companies buy lots of processing chips, they are wildly different thant a bitcoin ASIC. Fundamentally, all these companies looking to power portable hardware and are trying to make the least amount of heat and power draw while bitcoin asics are the polar opposite. Asic manufacturers are trying to stuff as much power into a small space as possible. Also, the asic market is tiny, a drop in the bucket compared to what these large chipmakers deal with. There is no real incentive for them to spend all that R&D on a niche market that wont give them much of a return.

Also, imagine if the big companies like samsung, intel, and apple did make a chip and mass produce it. The difficulty would spike like never before and all of you would be complaining that they are flooding the market just like you do with bitmain now.

The TLDR of this is factoring travel costs and everything else you are still paying a HUGE MARKUP on hardware and its just not worth it.

Paying $2500 for a $1500 piece of hardware is just stupid no matter where in the world you are buying it. Just buy from bitmain and realize that even if it takes them 60 days to ship, at $0.10 power the machine only profits $400 a month at today prices. That means after 60 days you have only made $800 of the $1000 premium you paid so its actually a net loss.

Paying $1500 and waiting 60 days to mine on it is better than paying a premium of $2500 to get it early. Buying from the third party there is no guarantee you will be receiving a new device and it will not be covered by Bitmain in case you need to warranty it.

It should be pretty clear that paying a premium to get the machine early in the end will cost you more money and more headaches for no good reason.

No.....no you dont. They were unreliable pieces of garbage.

I am not sure what kind of help people expect out of an internet forum when this is clearly an issue you need to take up with the manufacturer. Only bitmain can resolve your issue.

The one thing that scares me is the power supply. If its rated for 2100w and you are seeing a live power draw of almost 2200 at the wall that means they are pushing the crap out of their knockoff power supply. I worry about the longevity of it.

No overclock will make them run at 10th reliably. Someone is full of crap.

Also with the Avalon being the least efficient 16/14nm miner, overclocking it and taking it even further out of its efficiency range is a terrible idea.

No this will not be safe.

An s9 requires at least 450w per individual hashing board. This would completely max out one of the power supplies and most likely cause it to fail or shut off repeatedly from too much power draw. Also if you try to power a single board from two separate psus to balance the load you will kill the hash board.

ATX power supplies are not rated for sustained 24/7 at full load. There is a reason servers use much higher quality PSUs and not some ATX crap you would put in a home computer.

Think vehicle tires.

You need a 10 ply all terrain tire and you have been running off of a donut spare this whole time. Does it work? Yes. Will it end badly if you use it for too long? Yes.


Go get a real server grade PSU!
