Case fans are inexpensive and help improve airflow within your rig. To keep GPU cool while mining usually your rig has multiple cards for adequate space between GPU and other components. Make sure that you place the rig away from the walls. If you do that it will allow better airflow around the rig.
Make sure that the ambient temperature is not too high. To keep cool temp use windows, ductwork, box fans, etc. The thermal paste dries up over time, especially 3 years old GPUs. There are several best thermal paste for GPU in the market buy anyone of them.

CPU stands for Central Processing Unit and it refers to the component of a computer which has the responsibility for interpreting and then executing the commands from the hardware and software that is attached to the rest of the computer. Many different kinds of devices use CPUs- desktop computers, laptops, your tablet, smartphones, smart televisions and even games consoles.
Sometimes the computers hard drive is referred to as a CPU but this is completely incorrect and they are very different things. CPUs tend to be small and square with short metal connectors underneath them although some of the older models of CPUs have pins instead. When using a CPU it is common that they get very hot and this is why it is often necessary to attach a fan or cooler to the device to keep it at a safe temperature. For those with a greater need for cooling, it is possible to get water cooling kits and phase change units that keep it at a much more regulated temperature.
The last thing to note about CPUs is the fact that some will have a single-core processor, whilst others may have a dual-core or quad-core processor. The more cores that a processor has, the more powerful it is and the more instructions it can manage every second which means that its performance is much higher. Some CPUs have the ability to visualise two cores for each available core and this is referred to as Hyper-Threading , meaning that the potential power can be doubled That said, physical cores do tend to function better than virtual ones.
A GPU works specifically with the rendering of images, animations and other types of an image for the screen of the computer. GPUs are typically located on a plug-in card which is found either in the chipset on the motherboard, or in the CPU.
Although the GPU is used for 2D data as well as for tasks such as zooming or panning, it is an essential requirement for 3D animations and videos. The more high-tech and sophisticated that your GPU is, the better the resolution and speed will be when it comes to rendering videos and movies. A GPU processes multiple operations across multiple sets of data and they are often used as vector processors for various applications that require repetitive computations or actions.
When we refer to CPUs in the context of CPU mining, we are talking about the process of generating a cryptocurrency coin and securing the network it is running on. As we have already discussed, the CPU processor is found on any computer and these type of processors are used for mining when a coin is first released. This is due to the fact that coins at this stage are very easy to mine, but as the difficulty increases, it is necessary to upgrade the mining computer to something a little more powerful.
For example, back in the early days of Bitcoin, it was possible to use a simple CPU to mine but as its popularity grew, the hash rate of the network got to such a level that the number of Bitcoins mined by CPU mining became less than the cost of mining meaning that it became financially unviable. The short answer is that GPU mining is the more powerful and lucrative version of CPU mining and yields a much better return on investment.
GPUs offer a much higher level of processing power which in some cases are up to times more than that of a CPU. As mining is the process of solving complicated cryptographic equations and in order to do this, a lot of hardware power is needed. This was once done by CPUs, but then miners realised that a graphics card could do a much better and much more efficient job. In a regular setup, three graphics cards will be inserted into a mining rig and then set to work solving calculations in return for the cryptocurrency.
ASIC stands for Application Specific Integrated Circuit and it is a particular type of microchip that has been designed especially for an application such as a transmission protocol or a hand-held computing device. ASICs are used in a large range of applications such as personal digital assistants , environmental monitoring, and of course cryptocurrency mining. You can purchase an ASIC pre-manufactured for a specific purpose or you can custom manufacture it using a variety of components from a building block, for a specific need.
In terms of cryptocurrency mining, an ASIC is an integrated circuit that has been specially customised for the purpose of mining. They are more efficient, quicker, and mine more coins in less time than any other kind of processor. FGPA stands for a Field Programmable Gate Array and it is an integrated circuit which is configured by the customer or developer once it has been manufactured.
These blocks can be configured to facilitate and perform a range of complex combinational functions. FGPA mining is an extremely fast and efficient way to mine proof-of-work based cryptocoins. The integrated circuit is specially configured for Bitcoin mining but it is not as power-consuming as other methods. When we consider which is the best for you as a miner, there are several considerations to take into account.
Firstly, it depends on whether you are looking to mine for fun or curiosity , or whether you are actually looking to make some serious money from it. If it is the latter, then ideally you would opt for ASIC mining which offers much quicker, efficient, and low-cost mining capabilities meaning there are more rewards for you to reap. Using a graphics card, or a series of graphics cards in your rig will offer you the highest level of processing power.

Model: VII. 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. In that case, it might be worth considering, particularly if you live in an area where power isn't super expensive. At the same time, we strongly recommend against 'redlining' your card for maximum hashrate at all costs.
They will burn out if you run them that way. We also have serious concerns with any component temperature that's consistently at or above C or really, even 90C. Will it be long enough to recover the cost of the card?
That's the big unknown. Here's the thing to remember: Cryptocurrencies are extremely volatile. This means that, as fast as the price shot up, it could plummet just as quickly. At one point, it might have been possible to break even on the cost of a new GPU in a few months. These days, it would take more than a year at current rates, assuming nothing changes.
It could go up, but the opposite is more likely. Just ask the GameStop 'investors' how that worked out if you think the sky's the limit. Again, if you already have a GPU, putting it into service isn't a terrible idea — it's your hardware, do with it what you please.
