There are many instances of malicious software being attached to mining software packages. You have been warned! Before you get started building your Ethereum mining rig, check that you have all the components and tools below. Also, keep in mind that once you mine Ethereum, you will need a reliable hardware wallet. Secure your family's crypto assets with Ledger Holiday Sale! You need to take each GPU and plug each of the powered risers into them.

There will be a slot on each GPU that the riser fits neatly into. Source: wikimonks. Next, connect each GPU to the power supply unit. Use more power cables to do this. There should be some 8-pin cable holes towards the top of each GPU for your cables. Following this, you must hang the GPUs in the frame. By now, your frame should look rather cluttered with components, so we want to add the GPUs in the space at the top of the frame.

You can use the zip ties to hang your GPUs on the horizontal aluminum lengths at the top of the frame. On your computer download the Ethereum mining software you want to use and add it to your USB stick. Plug the USB stick into the USB drive on the motherboard and plug the ethernet cable into the ethernet cable socket on the motherboard.

Plug the monitor in and connect it to the mother board too. Turn the power supply on and use your power switch to turn the motherboard on. If you connected everything correctly, the GPU fans should start to spin, and you should see the software start to run on the monitor. How long it takes to mine an Ethereum block will depend on the number and power of your GPU units. All you need to do now is sit back, relax, and wait for your money to roll in!

Unfortunately, the above guide is just the basics. Your mining rig will probably look pretty ugly at this point. Instead of using the industrial-looking natural aluminum lengths, you could invest a little more and get some fancy colored ones. Also, black angled aluminum lengths are pretty common — and of course, black goes with anything! GPUs often have coloured on them and look pretty cool themselves.

You could match the color of your framework to the color of the detailing on the GPU itself. Using vertical lime green aluminum lengths and black horizontal pieces would certainly give your Ethereum mining rig a stylish finish! One option to make your mining rig look great is to add sheets of some material to enclose the entire unit.

Be careful when doing this, however. In the above example, we designed our mining rig to be as functional as possible with as little work. If you decide to add sheets to enclose the unit, you are restricting airflow. This is important since running a GPU hours a day will get very hot!

If you do want to enclose your cryptocurrency mining rig, make sure you add at least one fan to get rid of all that hot air. Alternatively, you could go for some see-through or semi-see- through material such as Perspex. You can then decorate the outside of the rig by using paints or by adding stickers of your favorite crypto projects.

In the above example, I used zip ties to hang the GPUs. This was to make it very quick and easy to replace GPUs if they burn out or you just want to upgrade them. If the appearance of your Ethereum mining rig is really important to you, you could use something a little more permanent. You could try drilling a hole in the mining rig frame and attaching a bracket to hang the GPUs off.

This will keep everything inside the frame itself and make the whole thing look that little bit more professional. You can go wild with lights. Just look at some custom high-end gaming PCs for inspiration. Source: masterwork. Another way to make your Ethereum miner look great is to add a monitor to the unit itself.

You can then choose to encase the whole thing or leave it open. Adding a monitor to your GPU mining rig will not only make it look cool but it will also mean you can use it in a smaller area of your home or office!

There are a few more things to mention before I finish up this guide though. First, you should shop around for the best price energy provider you can. You might think that the most expensive part of mining cryptocurrency is the price of the parts you use to build your mining rig. Electricity will seriously eat into your profits. Always go with the cheapest provider.

When it comes to making a profit, many people choose to trade Ethereum. If that's what you decide to do, then go for Coinbase , Binance or Coinmama. These cryptocurrency exchanges are among the most reliable ones. What do you think? Will you be building your rig? We do not publish biased feedback or spam. So if you want to share your experience, opinion or give advice - the scene is yours! Picking out the best crypto exchange for yourself, you should always focus on maintaining a balance between the essential features that all top crypto exchanges should have, and those that are important to you, personally.

That said, many users believe that Coinbase is one of the simpler exchanges on the current market. The exchange platform i. Binance acts as a middleman - it connects you your offer or request with that other person the seller or the buyer. When considering cryptocurrency exchange rankings, though, both of these types of businesses exchanges and brokerages are usually just thrown under the umbrella term - exchange. This is done for the sake of simplicity. No, definitely not! While some of the top cryptocurrency exchanges are, indeed, based in the United States i.

Coinbase or Kraken , there are other very well-known industry leaders that are located all over the world. While there are many reasons for why an exchange would prefer to be based in one location over another, most of them boil down to business intricacies, and usually have no effect on the user of the platform.

The Ethereum blockchain is in many ways similar to the Bitcoin blockchain, although it does have some differences. The main difference between Ethereum and Bitcoin with regard to the blockchain architecture is that, unlike Bitcoin, Ethereum blocks contain a copy of both the transaction list and the most recent state the root hash of the merkle patricia trie encoding the state to be more precise.

Aside from that, two other values, the block number and the difficulty, are also stored in the block. The proof of work algorithm used is called Ethash a modified version of the Dagger-Hashimoto algorithm and involves finding a nonce input to the algorithm so that the result is below a certain difficulty threshold.

The point in PoW algorithms is that there is no better strategy to find such a nonce than enumerating the possibilities, while verification of a solution is trivial and cheap. Since outputs have a uniform distribution as they are the result of the application of a hash function , we can guarantee that, on average, the time needed to find such a nonce depends on the difficulty threshold.

This makes it possible to control the time of finding a new block just by manipulating the difficulty. As dictated by the protocol, the difficulty dynamically adjusts in such a way that on average one block is produced by the entire network every 15 seconds. We say that the network produces a blockchain with a 15 second block time.

Any node participating in the network can be a miner and their expected revenue from mining will be directly proportional to their relative mining power or hashrate , i. Memory hardness is achieved with a proof of work algorithm that requires choosing subsets of a fixed resource dependent on the nonce and block header. This resource a few gigabyte size data is called a DAG. The DAG is totally different every blocks, a hour window called epoch roughly 5.

Since the DAG only depends on block height, it can be pregenerated but if its not, the client needs to wait until the end of this process to produce a block. If clients do not pregenerate and cache DAGs ahead of time the network may experience massive block delay on each epoch transition.

As a special case, when you start up your node from scratch, mining will only start once the DAG is built for the current epoch. All the gas consumed by the execution of all the transactions in the block submitted by the winning miner is paid by the senders of each transaction. Over time, it is expected these will dwarf the static block reward.

Uncles are stale blocks i. Valid uncles are rewarded in order to neutralise the effect of network lag on the dispersion of mining rewards, thereby increasing security this is called the GHOST protocol. A maximum of 2 uncles are allowed per block. Mining success depends on the set block difficulty. Block difficulty dynamically adjusts each block in order to regulate the network hashing power to produce a 12 second blocktime. Your chances of finding a block therefore follows from your hashrate relative to difficulty.

Ethash uses a DAG directed acyclic graph for the proof of work algorithm, this is generated for each epoch , i. The DAG takes a long time to generate. If clients only generate it on demand, you may see a long wait at each epoch transition before the first block of the new epoch is found. However, the DAG only depends on the block number, so it can and should be calculated in advance to avoid long wait times at each epoch transition.

Both geth and ethminer implement automatic DAG generation and maintains two DAGs at a time for smooth epoch transitions. Automatic DAG generation is turned on and off when mining is controlled from the console. It is also turned on by default if geth is launched with the --mine option. Note that clients share a DAG resource, so if you are running multiple instances of any client, make sure automatic dag generation is switched off in all but one instance. It is designed to hash a fast verifiability time within a slow CPU-only environment, yet provide vast speed-ups for mining when provided with a large amount of memory with high-bandwidth.

The large memory requirements mean that large-scale miners get comparatively little super-linear benefit. The high bandwidth requirement means that a speed-up from piling on many super-fast processing units sharing the same memory gives little benefit over a single unit. This is important in that pool mining have no benefit for nodes doing verification, thus discourageing centralisation.

In order to mine you need a fully synced Ethereum client that is enabled for mining and at least one ethereum account. This account is used to send the mining rewards to and is often referred to as coinbase or etherbase. Ensure your blockchain is fully synchronised with the main chain before starting to mine, otherwise you will not be mining on the main chain.

This is no longer profitable, since GPU miners are roughly two orders of magnitude more efficient. However, you can use CPU mining to mine on the Morden testnet or a private chain for the purposes of creating the ether you need to test contracts and transactions without spending your real ether on the live network.

The testnet ether has no value other than using it for testing purposes see Test Networks. When you start up your ethereum node with geth it is not mining by default. To start it in CPU mining mode, you use the --mine command line option. The -minerthreads parameter can be used to set the number parallel mining threads defaulting to the total number of processor cores.

You can also start and stop CPU mining at runtime using the console. Note that mining for real ether only makes sense if you are in sync with the network since you mine on top of the consensus block. In order to earn ether you must have your etherbase or coinbase address set.

This etherbase defaults to your primary account. Note that your etherbase does not need to be an address of a local account, just an existing one. There is an option to add extra Data 32 bytes only to your mined blocks.

By convention this is interpreted as a unicode string, so you can set your short vanity tag. You can check your hashrate with miner. After you successfully mined some blocks, you can check the ether balance of your etherbase account.

There's a lot to discuss with these charts, specifically, what do we mean by "tuned" performance? The answer: It varies, often massively, by GPU. After the initial article, we've updated and added more GPUs, but we've skipped the "stock" testing and only included our tuned results.

Let's talk about the big picture quickly before we get into the details. Modding those with better thermal pads, or buying a third party card, can boost performance and lower memory temperatures. That's because Ethereum hashing depends quite heavily on memory bandwidth.

You can check out the power chart, but the overall efficiency chart is more important than raw power use. Most of the cards are pretty close in terms of overall efficiency for Ethereum mining, though the additional GPU cores on the XT and XT ended up dropping efficiency a bit — more tuning might improve the results, particularly if you're willing to sacrifice a bit of performance to reduce the power use.

Finally, we have temperatures. These are GPU core temperatures, but they're actually not the critical factor on many of the cards. AMD's cards ran hot at stock settings, but all of the cards benefit greatly from tuning. The cards settled in at degrees Celsius, with GPU clocks fluctuating quite a bit. This brings us to the main area of interest. Let's start by noting that every card model is different — and even cards of the same model may vary in performance characteristics.

That's because EVGA appears to have put a lot of effort into cooling the memory. Let's take each card in turn. Power use also dropped to W, is quite good considering the hash rate. If you don't mod the card to improve GDDR6X cooling, you'll typically end up at C depending on your card, case, cooling, and other factors , and the maxed out fan speed is not going to be good for fan longevity.

Consider yourself warned. Again, maxing out fan speeds and memory clocks while dropping the GPU core clocks and power limit are key to improving overall hash rates. Which brings us toa card that we've since removed from the charts.

Then we overclocked the memory by MHz base clock, which gave a final speed of 20Gbps the Ampere cards run at 0. It's not ideal, but at these temperatures a 4C difference can be significant. Our initial results were poor, as these were the first cards we tested, but we've revisited the settings after looking at the RX series.

We were able to add MHz, giving a You'd think that wouldn't be sufficient, but boosting the GPU clocks up to 1. Performance was very close to the while using less power, making this the overall winner in efficiency. Our tuned settings ended up with higher clocks due to the factory overclock and more power use than the Ti Founders Edition, but basically the same hashing performance.

The cooling on this card isn't nearly as robust as many of the other GPUs. The GPU clocks can go very high at stock, but the memory bandwidth appears to be the main bottleneck. Running with GPU clocks of 2. More importantly, power consumption took a massive dive, and efficiency improved to one of the better results in our testing. But this actually isn't AMD's best overall showing.

At the same time, power requirements dropped substantially, from W to W. However, the memory proves the deciding factor once again. That resulted in a MHz clock compared to MHz at stock, but fan speed was higher this time. Boosting the clocks back to 2. The efficiency looks good, but the raw hashrate is definitely lacking — it's only marginally faster than a RX 8GB from five years back.

After the testing we've completed, one thing we wanted to do was look at real-world profitability from mining. There's a reason people do this, and results can vary quite a bit depending on your specific hardware. We've used the optimal tuned settings, as well as power draw figures.

However, note that the power draw we're reporting doesn't include PSU inefficiencies or power for the rest of the PC. We're mostly looking at reference models as well, which often aren't the best option, but here's how our data compares to what NiceHash reports. There are some interesting results. Our stance is that this is a Very Bad Idea tm. Not only will the fans make a lot of noise, but they're also destined to fail sooner rather than later.

If you're okay replacing the card's fans in the future, or if you want to mod the card with better cooling pads in the first place, you can definitely achieve the NiceHash performance figures. Power use as measured using Powenetics would of course increase. We were relatively close on the Ti performance, and our earlier power data showed much better results than NiceHash, but now those figures have been updated and are slightly lower than our measured power.

The RTX meanwhile ended up with similar performance, but our power results were significantly higher — perhaps our EVGA sample just wasn't a good starting point. The current thinking for a lot of miners is that Nvidia's RTX series cards are superior to AMD, but that's really only true if you look at pure hashrates on the and Factor in power efficiency and things are much closer. Besides, it's not like you can buy any of these GPUs right now — unless you're willing to fork out a lot of money or have some good industry contacts for building your mining farm.

The principles we've outlined above generally apply to the older GPUs as well. We're going to skip all the baseline performance metrics this time, and just jump straight to optimized performance. Note that outside of the RX and , and the three GTX variants, all of our tests were done using the reference models from AMD and Nvidia, which tend to be more of a baseline or worst-case scenario for most GPUs.

We'll list our optimized settings below, but here are the results. Our Vega cards are also reference models and were far more finnicky than other GPUs. For Nvidia's Turing GPUs, performance again correlates pretty much directly with memory bandwidth, though with a few interesting exceptions. Notice that the Super, Super, and Super all end up with nearly identical performance?

That's not an error. The odd bit is that the Super requires substantially higher memory clocks to get there. Most likely the memory timings on the GDDR6 in the Super are more relaxed looser , so even though bandwidth is higher, bandwidth plus latency ends up balancing out. The Ti and Super are basically the same speed, though we had better luck with memory overclocking on the Super. That reduces power use and temperatures and boosts overall efficiency. Stepping back one generation further to Pascal GTX series , the approach changes a bit.

Maximum memory clocks are still critical, but core clocks start to matter more—the architecture isn't tuned for compute as much as Turing and Ampere. We got our best results by overclocking the GPU core and memory speed, but then setting a power limit. Tweaking AMD's previous generation GPUs is a bit different, in that rather than limiting the power, the best approach is to tune the voltage and clock speed.

Not surprisingly, the older the GPUs get, the lower the hash rates and efficiency become. Let's start with the previous generation and move back from there. Move back to the Vega architecture and the large memory bandwidth that comes from HBM2 comes into play. But Vega was also a power-hungry architecture, and it benefits from turning down the GPU clocks. That gave mining clocks of MHz. Vega 64 and Vega 56 used similar settings, but half the memory capacity and bus width limits performance quite a bit relative to the Radeon VII.

Also, our results on the reference blower cards are probably far less than ideal—just about any custom Vega card would be a better choice than these blowers. We experienced a lot of crashing on the two Vega cards while trying to tune performance. And then there's Polaris. Much like the Pascal GPUs, our tuning efforts took more time and effort.

Besides setting a low voltage of mV, depending on the card, we set the memory timings to level2 in Radeon Settings, and that gave the best results with reasonable power use. Here's a gallery of all the 'tuned' settings we used for the legacy cards. Use at your own risk, and know that some cards prefer different miner software or simply fail to work with certain miners. Is it possible to improve over our results?

This is just a baseline set of performance figures and data, using our specific samples. Again, non-reference cards often perform a bit better, and if you want to research VBIOS flashing and hardware modding it's possible to hit higher hash rates. But out of the box, these are numbers that just about any card using one of these GPUs should be able to match. This brings us to the final point we want to make. Suppose you already have a graphics card and want to mine using your GPU's spare cycles.
