Gavin Download is one of the few people in the world free are known to have corresponded directly with Satoshi Nakamoto. For example, a download transaction feature design used within a block: I see it as a stealth hardware bitcoin, so for me it wins. Current best practices for transaction tracking dictate that a asic should be tracked by the transaction outputs UTXOs it spends as inputsas they cannot be changed without bitcoin the transaction. In my case, I am keeping my rigs is software a pretty small room, which is software. Even if you are free handy with electronics, and know about computers or the components asic comprise them, then here are a design guides on how to build your own computer:. Rewards are calculated proportionally to scores and not to shares.

After many tests, and attempts to keeping the room cool, I had no choice but to build an exhaust system. Basically, I cut a large circular hole in the wall closest to where the miners would be flushing out hot air. Then I place an industrial exhaust fan which would suck the hot air out of the room. Yes, I am making sound a lot simpler than it actually was.

Here is a pic: If it is winter time and you have a window nearby, it would be okay to keep that cracked to let cool air in, although it is not recommended to keep hardware exposed to natural outdoor weather.

In doing so, you can start dealing with other issues such as humidity, which will factor in on hardware performance and shelf life. Easiest thing to do is to get yourself a Digital Temperature Monitor.

If you are not onsite and want to check the temperature remotely you can get one of these USB Temperature Sensors. It is a measurement device using a USB port to connect to a computer or other machines. Here is a screenshot:. Yes GPUs can overheat! That is why it is so important to keep your room and rigs cool, so your GPUs have optimal temperatures to operate in. Cramming 3 GPUs in a mid-tower case was not easy. There needs to be sufficient space between the cards so that the fans which are cooling the heat sinks have enough airflow.

I used small pieces of thick rubber tubing to pry apart each card, so that I would have at least half and inch between each GPU. This depends on your operating system. Please see section If you are using Windows: If you are using linux: Measuring your GPU temperature is relatively easy. If you have ATI Catalyst installed if not see section On that screen you will be able to see the temperature of the GPU usually measured in Celcius.

Overclocking your GPU can affect the temperature, and is discussed in section 9. Another way that I like to measure my GPU temperature in Windows 7 is through GPU Observer, which is a desktop gadget that you can download and display right on your desktop.

It shows the temps, fan speed, and memory usage — very useful! You can run the following command to get the temperature of all the GPUs in the system:. My machines currently have 3 GPUs installed, with a Watt power supply.

Currently each machine at full load utilizes about 6 Amps, about Watts, which is 0. An average size residential circuit breaker is about 20 Amps.

If you exceed 20 Amps of power on a 20 Amp circuit breaker, you will cause too much power to be drawn, and the circuit breaker will shut off to prevent damage or other failures. Therefore, it is important that you are aware of how much power is available on the circuit which your miners will be plugged into.

In my scenario, I originally only had about 20 Amps, and I needed to power 3 Machines. Although each machine was only using about 6 Amps a total of 18 Amps, the circuit breaker would still shut off periodically. Sometimes the Amp usage could jump for just a second, and it would be enough to trigger the circuit breaker to shut off. Due to this, I had to install additional circuit breakers, and fish some new lines to the room that was powering my Bitcoin Miners. You always want to leave a little overhead, and not max out the lines.

Below are some pictures of the process in running new lines, leaving me at a total of about 80 Amps. If you are unsure how to install a new circuit breaker, or run your own electric lines please consult the assistance or services of a professional electrician!

If you are capable of handling this yourself, here are some helpful links:. Be sure that you evenly supply power to your GPUs! I made the mistake of running too many watts through a single wire supplied from the power supply. I had various other connections, including a molex splitter which was plugged in to other devices such as fans etc and eventually connecting to the GPU s.

Due to the fact that there was so much power draw through one wire, they quickly burned out, and could have caused serious damage or electrical fire. I would stay away from using any splitter connecters or thin wires when powering your GPUs.

Thankfully no serious damage occurred, just needed to replace the wires. In order to figure out how much you will be paying additionally for your electric bill each month we need to do some basic math.

Measuring your power utilization is very easy. There are various products like this one available, so find one that suites you. Be sure to monitor the usage at full load. Overclocking is a term used when running a microprocessor faster than the speed for which it has been tested and approved. Overclocking is a popular technique for squeezing out a little more performance from a system. In many cases, you can force a GPU to run faster than it was intended.

Overclocking does come with some risks, however, such as over-heating, so you should become familiar with all the pros and cons before you attempt it. Overclocking is also sometimes called speed margining. I would say it is pretty safe to overclock any GPU at the right settings, you can certainly get more performance from your GPUs if you overclock. This process took some trial an error to get the most out of my GPUs without the machine freezing up, but after a few hours of testing, here are my stats:.

You will notice, I increased the clock speed, which is the overall performance, but, I decreased the memory usage. The reason for this is that high memory usage does not provide any benefit in Bitcoin mining. By decreasing the amount of memory it will also help with suppressing the heat. See the screenshot below:. The same instructions are provided below:.

This is a small guide for overclocking your ATI card under Linux. This guide targets Ubuntu, but it should be the same for any distro. If you type the command aticonfig in a terminal, you will get several config.

This is a list of Overdrive related options:. Next we get the current clocks and the valid overclocking range for your card: You can also use Overdrive for Crossfire setups.

The process is identical, with the difference that you need to specify the device being overclocked. There is also a stress test available for Overdrive. For me this never works and I have yet to get an answer on this from any ATI dev. But you can try it and see if it works for you:. Another way of stress testing is to run furmark. Same pre-requisites still apply, since this are just frontends for Overdrive:. ATI Overclocking Utility 32bit 64bit. This machine is actually my primary node connection point for overseeing my Bitcoin mining rigs.

It also is capable of monitoring the temperature in the room. All you need as far as software is Putty to connect to your miners via SSH, and a few bat scripts. I think it is very important to have a central node where you can control and configure all these things, it makes it a lot easier to manage. You want to check on your Bitcoin miners at least every few days to make sure everything is running smoothly.

If you keep them close by in your home , then it will probably be easier to monitor and manage them. My Bitcoin miners are not kept in my home, so I do my best to stop by the location at least once a week. You can use the following protocols to login to your windows machines remotely to manage your Bitcoin miners: If you are using Linux: You can use SSH Command Terminal , or if you want a visual remote connection, take a look at this article: I like to use GUIMiner.

I like to use poclbm. The ATI Catalyst Control Center is a 3D acceleration control application that enables you to control the functionality of your graphics card. ATI Catalyst Control Center can be used to fine-tune your graphic settings, enable or disable connected display devices, and change the orientation of your desktop, etc.

Many features present you with a preview of your changes before they are applied. The appropriate ATI Catalyst Control Center version usually comes with your graphics card, so you may want to check with your vender for a specific version.

OR You can also download this online here: You can use the following guide on to install it on Ubuntu You can also use your package manager to search and install the latest software. I highly recommend using LinuxCoin. It is a small Debian Wheezy based OS created just for the bitcoin community. Everything is pre-installed and is ready to go. It saves a lot of work and headache, this is what I use. Best of all, it can be run directly off a USB flash drive!

Which answers our next question…. Get more info here: My friend Brandon and I put together a very nice automated script that sets up our entire bitcoin mining environment. This code has been setup to use 3 GPUs. Looks like the following: Each one of them point to my first Bitcoin mining rig identified as M1. The IP address of M1 is: You will see I input: I will set this accordingly to each GPU, so the second one would simply be: This command will actually execute out bitcoin miners to run.

This way, when each GPU terminal windows pops up, it has the appropriate title in the title bar so I can identify it. When we are all done with Putty, I create a. This code actually runs putty. When this putty runs, and uses the profile we created, it will automatically run that command, upon login.

Create setup script file on linux To use this code, you will need to create a file on Linux and copy and paste the contents inside. Save it as a. Then you can execute this file by running:. Pooled mining is an approach where multiple generating clients contribute to the generation of a block, and then split the block reward according the contributed processing power.

Pooled mining effectively reduces the granularity of the block generation reward, spreading it out more smoothly over time. Solo mining is when a miner performs the mining operations alone without joining a pool. With increasing generation difficulty, mining with lower-performance devices can take a very long time before block generation, on average. For example, with a mining speed of Khps, at a difficulty of which was in effect at the end of December, , the average time to generate a block is almost 2 years.

To provide a more smooth incentive to lower-performance miners, several pooled miners, using different approaches, have been created. With a mining pool, a lot of different people contribute to generating a block, and the reward is then split among them according to their processing contribution.

This way, instead of waiting for years to generate 50btc in a block, a smaller miner may get a fraction of a bitcoin on a more regular basis.

A share is awarded by the mining pool to the clients who present a valid proof of work of the same type as the proof of work that is used for creating blocks, but of lesser complexity, so that it requires less time on average to generate. Get all the details here: Each submitted share is worth certain amount of BTC. It is risky for pool operators, hence the fee is highest. Like Pay Per Share, but never pays more than the pool earns. When block is found, the reward is distributed among all workers proportionally to how much shares each of them has found.

Similar to proportional, but instead of looking at the number of shares in the round, instead looks at the last N shares, regardless of round boundaries. Score — Score based system: Each submitted share is worth more in the function of time t since start of current round. For each share score is updated by: Rewards are calculated proportionally to scores and not to shares.

See the rest below and check out this link for details: A bitcoin mining proxy is a a multi-pool, multi-worker proxy for Bitcoin miners, supporting long polling and pool failover. Here is a link to what seems to be the only good available Bitcoin Mining Proxy: Bitcoin , Internet , Technology.

So a friend of mine wrote an extensive guide to Bitcoin. Your recommendation in 7. You can find a simple explanation in http: Yes, technically you are correct. However, I was just going based upon the cost of power to run the machines. This calculation is assuming that the AC continues to run at the users regular schedule with no modifications. A very good guide on how to build a Bitcoin Mining Rig Cluster bitcoingo. Also consider the power supply efficiency when calculating the power consumption.

I see that some people are using more than 10 graphics card for their mining rig. Do they use multiple computers for this or just 1 computer with mulitple power supply to provide the needed energy?

I want to power up my second GPU, but can I use a second power supply to provide the energy or do I need to buy a new power supply? My current one is watt only, power up 2x would be too much. However I still have a watt left. Not sure whether I can combine them. I am sure there are many people who are faced with the same problems I recently had. Home Portfolio Experience Blog Contact.

NewEgg or Amazon same price. Standard Return Policy In Stock. Intel Core i Sandy Bridge 3. Two years have passed by and some think that the AntMiner S7 is no longer viable for mining. The reason is simple: Your question probably is — why is this ASIC in this list? The reason is simple — if we think of mining as a way to convert fiat currencies into BTC, then the Antminer S7 might be considered a great option. The main pro of this ASIC is its durability.

Many S7s have been mining for two years now and they keep hashing the way they used to do. This is a good sign and it makes the S7 a good pick for those who are not rushing anywhere and who want to play it safe. The AntMiner S7 features a strong metallic case and dual fans for stable cooling.

It is indeed quite noisy with tests showing a sound level of about 63 dB. However, by some reason, the manages to output some nice hashrate and one year later it is still considered a solid miner. The Avalon is based on 16nm chips, which allows it to be more power efficient than the aforementioned Antminer S7.

In fact, the 16nm technology is still considered close to the cutting edge. This means that the ASIC still got a long life ahead. ROI-wise, the AvalonMiner is rather an interesting case. As for today, it features ROI of somewhere between 8 and 12 months , depending on the price you pay for it. Back when the miner was released, in December , its ROI was 24 months. The power efficiency and durability of the allow it to stand the test of time and actually become more profitable by the day.

If you like the AvalonMiner , you might like its successor too — the AvalonMiner This miner is still based on 16nm chips too, however due to some important software and design optimization, this new model features even higher hashrate. Efficiency-wise, the Avalon still got the same 0. The AvalonMiner looks really solid — it features an aluminum shell and custom heatsink with airforming technology.

This is even more believable since Canaan has a reputation of manufacturing quality products. Otherwise, it might be a good idea to keep it in a dedicated mining farm whether it is a mining office or a properly configured garage. If you want a miner especially designed for home mining, then check the next one in the list.

While the miner is big and heavy, it produces only 51 dB of noise. According to loudness scales, 51 dB can be compared to the noise level of a quiet office or a refrigerator. This is also why few people are willing to sell their R4. New miners are not available for sale either. It features great power efficiency, as well as a solid metallic shell and equally good cooling system.

It features 16nm chips that output between While ASIC availability changes overnight and tomorrow things might be different, today the AntMiner T9 is on sale at a reasonable price in several sites. As for today, the AntMiner S9 is widely praised as the best Bitcoin miner. I completely agree with the public opinion on this miner.

The S9 features better power efficiency than the T9, which makes it even a better option for long-term Bitcoin mining. In fact, I still got to find a miner that would have better power efficiency than the Antminer S9. This ASIC is easy to operate and it takes only a couple of minutes to set it up.

I agree that not anyone can afford to have their own ASIC at home for various reasons. Or there might be no room for a miner in your apartment. Or, depending on where you live, electricity might be really expensive at your place rendering mining unprofitable. There are several reasons why far from everyone can mine from their homes.

Luckily for us, there is a way to enjoy the benefits of mining without the need to have a miner at home. I am talking about Bitcoin cloud mining.

There are companies who rent hashrate. Investing in a cloud mining contracts can be compared to investing in a company — you pay a fixed amount upfront and then your income depends on how the value of the company in this case, the value of the cryptocurrency evolves. Electricity and maintenance fees are usually included in the price in the case of a limited time contract. Usually, cloud mining contracts offer a ROI of 18 months. I am talking about legit companies here.

Scam ones often attract unsuspecting victims by offering them months ROI contracts. The two companies I am going to talk about here have stood the test of time. That being said, there is always that guy who gives negative rating to a functioning and honest company. Also, as always, please take what you read with a grain of salt and make your own research. Genesis Mining owns farms in Bosnia , China and now Iceland. The company was founded in late and since then it proved to work as intended.

They do face some technical difficulties from time to time that result in payoff delays but at the end of the day people still get their money. Most negative reviews about Genesis Mining are based on this. The reason is simple — credit card payments have a 30 day refund policy, so anyone can potentially exploit this to get infinite hashrate from GM for free. This is why Genesis Mining freezes your income for the first 30 days in order to avoid being scammed by its own customers.

People who bought their contracts with Bitcoins start to get their profit the same day. However, the minimum payout amount is Funds will be accumulating until the amount to be paid becomes more than This means that people who got their hands on small Bitcoin contracts will not get paid on a daily basis.

The next company in the list is HashFlare. HashFlare is younger than Genesis Mining, but it managed to achieve popularity rather quickly thanks to its competitive rates.
