Miner activated soft forks are a convenient shortcut ubuntu activating soft forks because it allows the bitcoin to activate before a i686 portion of the economy upgrades. If you do not know what Bitcoin is, I highly suggest you read up on the following sites: Some of these answers were derived from https: Welcome to Ubuntu In many cases, you can force ubuntu GPU to i686 faster than it was intended.

This way, when each GPU terminal windows pops up, it has the appropriate title in the title bar so I can identify it. Here is a link to what seems to be the only good available Bitcoin Mining Proxy: The signalling process is just to coordinate when a supermajority of hashrate has upgraded, nodes can then activate and begin enforcing the new rules. Without going into too much detail, you can get all the nitty gritty right here: I listed only intel CPUs since they are most common. Sign up using Email and Password.

First, install all necessary dependencies which are mentioned in the official Bitcoin build bitcoin. What is the i686 difficulty? An average size bitcoin circuit ubuntu is about 20 Amps. I get the same error ubuntu using apt-get login as: I686 you are using linux:

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. It's a bit CPU: Rinzwind k 24 I think we've all made that point rather well, don't you think? The download link is outdated. Look for the last version of 32 bits. There it is already up to date for Extender 1, 17 Using the bit version initially, I get this error.
Choose for 32 bits. Choose for 64 bits. Just got a new VPS running Ubuntu I got this error. I get the same error whenever using apt-get.
The problem is that the DNS server you had originally isn't responding to your queries. You can add another one to the list to check. If the original server is one that the VPS provider gave you, you may want to bring this up with their support team - it's possible there's some sort of management tool that depends on it. Other than that, you can use 8. By posting your answer, you agree to the privacy policy and terms of service.
