Mining in a pool setting actually doesn't require all that much bandwidth. This is because you get block templates sent to you and that single template can be used by all 100 miners. A block template isn't very big, it's less than 1k and looks something like this:
You can't mine Litecoin with a Bitcoin miner. Bitcoin uses sha256 hashing, Litecoin uses Scrypt, which is about 1000x slower even when implemented in an ASIC, which is why you are calculating ridiculous profit numbers.
I set up my rasp pi b+ and U3 mining rig using the instructions in this forum post, with screen and cgminer.
The command relevant to over clocking the raspi that I used is the following:
sudo ./cgminer --bmsc-options 115200:0.57 -o POOL -u USERNAME -p PASSWORD --bmsc-voltage 0800 --bmsc-freq 1286
Those last two options (bmsc-voltage and bmsc-freq) are ...
The AntMiner S9i 13.5 TH/sec model requires 101.5 Amps DC. Since power (watts) is equal to voltage multiplied by amps, the total power consumed by the AntMiner is 1218 watts (+/- 10%). Note, this is regardless of whether that's AC or DC, and regardless of voltage. 1218 watts is 1218 watts, or if you run it for an hour, 1.218 KW/hr. In my case, that works ...
An Antminer U3 is a SHA256 miner, it can not mine anything else. The shares are being rejected because they are effectively nonsense to the receiving pool, as they do not satisfy the difficulty requirements they have asked for.
I live in North America as well and just wanted to let you know that even though 110V is the most common wall socket voltage you've actually already got 220V coming in to your house. There are 2 110V lines 180° out of phase from the other ... yadda yadda, some technical mumbo-jumbo...
Long story short, as long as you live in a building where you have ...
No. Bitcoin does not use Scrypt, so you cannot use something that mines Scrypt to mine Bitcoin. Furthermore, the Antminer S3 is a Bitcoin miner, it can only mine SHA256d coins, such as Bitcoin. So it cannot even use the Scrypt algorithm or mine any coins that use Scrypt.
This is a scam. Block all contact with this person and do not send any money, passwords, keys, or anything else.
Your friend is right, there is no such thing as mining "with" somebody's Bitcoin. Mining requires specialized hardware (such as the AntMiner S9, which is a real device) but if one has that hardware, one doesn't need access to additional coins ...
As more people contribute to mining, Bitcoin automatically adjusts the "difficulty" so that the number of new bitcoins created by mining is roughly the same over time. The difficulty has increased rapidly in the last few months, and in fact it has nearly doubled since November 2015. This matches with your performance numbers. Your existing hardware will ...
You are looking at a Bitcoin miner, not the Litecoin miner which you need for Scrypt hashing so the estimates will not even be close.
Once you find the correct type of script miner, keep in mind that
Projections are based on the costs that you enter (including energy costs) so only you can know how accurate they are.
Calculations focus on current ...
This is a known and notable problem with Antminer U3s. It's discussed at various locations around the Web.
The design couples the USB and miner +5V power rails, which is not good practice. USB interfaces should be both electrically and optically isolated. When a unit goes ZOMBIE, it generally requires unplugging and replugging to restart it, which fits ...
I am going to answer my own question and hopefully it will come in handy for someone else.
While I understand that it might be a bit of an overkill pricewise but this solution works for me and has been working for 6 month now.
I power each of mine Antminer S9 with EVGA SuperNOVA 1600 T2 80+ TITANIUM
This is how it looks at home https://www.youtube.com/...
The AntMiner S9 manual is available at https://shop.bitmain.com/files/download/AntMiner%20S9%20Installation%20Guide.pdf
The manual says:
The AntMiner S9 can be set up with three mining pools, with decreasing
priority from the first pool (pool 1) to the third pool (pool 3).
The pools with low priority will only be used if all higher priority
A solution, but still not optimal for me, is on a Bitcoin Forum posting.
The server grade HP DPS-800GBA connectors are completely incompatible with FCI PWRLOPRO connector that my existing server-grade PFE1100-12-054RA PSUs connect to.
Wound up canabalizing the Coolmax ATX cables. Only needed to solder the ends of the cables to prep them for crimping into ...
I have TechnoBit Hex miners running BlackArrow ASIC chips and my equipment fluctuates a lot. I mine with the 'Discus Fish' Pool (aka F2Pool) and they let me view my hashrate on their website on a really fancy graph. My 1200 GHs dips from 900 GHs up to 1300 (occasionally), but in the end I do get a nice even 1150 / 1200 GHs.
The software (Cgminer) does ...
Check your rpcallowip configuration, you will need to explicitly allow connections incoming to your RPC port from the network. If your local network for example is 192.168.0.x, the rpcallowip configuation in your bitcoin.conf will need to be 192.168.0.0/24 (this is CIDR notation).
The ASIC "arms-race" is all about having cutting edge technology. In a recent Motherboard article about a mining farm, the hardware was not even allowed to be specified.
Consider also that both SHA256/Scrypt ASIC manufacturers were clamoring to bring smaller nanometer sized chips - and the associated R&D costs - and it's probably more a question of why ...
I have 2 u3 antminers running on a raspberry pi b+
I could not get my u3 any faster until i used minera software,set to cgminer (offical)
with command: --au3-volt 830 --au3-freq 250.0 In the settings menu
it will run at 62-63 GH/s.
you can download it hear http://getminera.com/
Using CGMiner 4.9.0
I have been trying for MONTHS to get all five of these to all work at the same time without ZOMBIE
and ERRORS that make the whole process a waste of time.
I did the Zadig thing, a million times, can do it in the sauna, while reading bad Hungarian poetry.
All my devices are running the right drivers.
I tried new power supplies, new cables,...
"Our ASIC chips, like those of some other manufacturers, have a circuit design that supports ASICBOOST." - Bitmain statement
Bitmain claims that it wasn't used on mainnet. It is currently unknown how to make use of the feature. Likely, you'd need custom firmware and software.
Edit: Here's someone on reddit describing how to activate ASICBOOST: https://www....
The L3+ is the best option right now (however if you're ordering now, you won't get a new one for some time, and the second hand ones are being resold for huge profits), however this will change as more of them are made/released.
The L3+ is a Scrypt miner, so it could in theory mine any Scrypt based coins, Litecoin being the big one.
Bitmain don't appear ...
I was running AntminerS9 on 120 volt without any problem but it will consume almost 12 Amps. Normal home supply is only 100Amps so in order to save amps I had to change it to 220 volt by installing new circuit breaker. With 220 volt it will consume only 6Amps (approx)
14nm will hash more with the same power consumption of a 22nm assuming your basing it on power only. But if both were 1/ths the 14nm would save more electricity. Obviously the 14nm would cost more as its newer tech. You'd have to weigh your electric cost vs hashing power.
The Antminer D3 spec states that it is a miner for the X11 hashing algorithm.
Bitcoin uses SHA-256d as its hashing algorithm. The Antminer D3 cannot mine Bitcoin, but only X11 based currencies such as Dash.
Same difference minus the 20 Watts of savings as mentioned above. It also seems they are dropping the price and moving bountiful amounts compared to before. Sites like Blokforge https://blokforge.com/product/bitmain-antminer-s9i-14-th-s/ are carrying hundreds of these units unlike any time in the past where units were limited to 1 or 2 per person.
The mining hardware industry started very recently and their chip fabrication technology was way behind that of traditional chip manufacturers (ie Intel, AMD).
Chip energy efficiency depends on the distance between the transistors of a chip. The closer the transistors are the better. Intel produced their first 14nm (distance between transistors) in 2014. ...
