VRAM (video-random access memory or video RAM) is a special kind of memory present in the dedicated GPU or graphics card. It stores images and videos before and after processing them. Mostly, powerful graphics cards have larger VRAMs. It is also the reason behind their high performance and efficiency.
This article will discuss the importance of the amount of VRAM when mining. First, we will clarify our VRAM concepts and know where it is installed. Then, we will discuss other aspects of VRAM and its relationship with GPU. Let’s start with the answer to the main question.
Is The Amount of VRAM Important When Mining?
The amount of VRAM is significant when mining. More VRAM means you will mine more data. It is because when you mine something legal, you use a dedicated GPU, and this graphics card stores mined data in its dedicated memory, known as VRAM. Hence, a more considerable VRAM amount means more and faster mining.
You must have noticed that powerful GPUs not only have more VRAM, but they also have a faster one. These two factors make those GPUs powerful, including the graphics processor installed on the graphics card. This is because a VRAM stores data before and after processing when mining.
- Multiple GPU
Most data scientists or miners use a rig for installing multiple graphics cards. By using this setup, not only do they increase the parallel processing and the processing power, but they also increase the amount of VRAM. That is why such a setup mines faster and gives you a more significant profit.
- More VRAM
Every dedicated graphics card has some VRAM, from 2 GB to 24 GB. More VRAM stores more data than GPU processes. You can use a graphics card not only when it has more video RAM but also when its size is larger. Memory BUS makes a GPU fast by connecting a graphics card to VRAM.
- More Storage
The more the memory BUS, the faster the memory is as it determines its bandwidth and can transfer more data toward the VRAM. During mining, the data is stored on the storage media such as SSD, M2 SSD, HDD, etc. Hence, it also means that your graphics card will process more data and send it to storage faster.
The most important thing when mining is the rate. The rate depends on the software and algorithm used for mining and the memory manufacturers. Samsung VRAM is considered the best for mining, and then comes Hynix. But as long as the amount of VRAM is enough, you need to worry about this.
The other VRAM factor affecting the GPU mining process is its temperature. VRAMs are IC chips on a graphics card, and they become very hot when mining as they have to store the data and process it using some hashing algorithm. It is crucial to keep their temperature within the acceptable range.
We will add two methods if you want to check the total size of your GPU’s VRAM. The first one is the easiest, and it is for Windows users because most people use Windows operating systems (OS). The second method is universal; you must download and install free software.
How to Check Your GPU VRAM Size?
Checking your GPU VRAM size is easy, especially when using a Windows operating system such as Windows 10/11. Right-click the taskbar and select the “Task Manager” option from the menu. A window with multiple tabs will pop up. Here, you need to select the tab named “Performance.”
After this, you will see a list of the basic hardware in your computer system. Select the “GPU” option at the bottom, showing you the stat about your graphics cards. You can see the total GPU, dedicated, and shared memory here. This memory is the size of the VRAM in your graphics card.
To check the total size of your VRAM installed on your graphics card, you can download a freeware named CPU-Z from its official website. After downloading and installing it, just open it and let it collect the stats about your hardware. If you open it for the first time, it might take some time, depending on your PC.
As it opens, you will see multiple tabs on its window. Select the tab named “Graphics.” Here, you will see the “Memory” section in the bottom left corner of the UI of our CPU-Z. You can see the size of your VRAM and the other stats such as its BUS width, clock speed, etc.
What is The Difference between GPU and VRAM Temperatures?
GPU or graphics card and its memory VRAM are electronic components. And when electronic components work on electricity, the current passes through them. As a result, different amounts of heat are generated in them. We call this heat temperature. GPU and VRAM temperatures are nothing but their generated heat.
GPU (graphics processing unit) is a separate entity from the VRAM, and the heat it generates is called GPU heat. GPU is a graphics card’s processor, similar to a computer’s CPU. It generates different amounts of heat in different states. An idle GPU is less hot than a working GPU.
The same case is with the VRAM. When it does more hashing during mining, its temperature rises compared to its temperature in its idle state. The graphics processor and the VRAMs are only IC chips on a graphics card. Because of their heat, some people install advanced liquid cooling systems on their PCs.
The optimal VRAM temperature is between 79° C to 95° C (from 174°F to 203°F). Any temperature above this temperature is considered bad, as the VRAM of your graphics card is becoming overheated. That is why different cooling methods and kits keep the GPU and VRAM temperatures as low as possible.
You must solve this issue if you have been experiencing high GPU and VRAM temperatures, even though the ventilation and cooling systems are advanced. Your graphics card may be an old piece of hardware with expired thermal paste and thermal pads. Replace these two things ASAP.
When mining professionally on a large scale, a specially built frame is called a mining rig. A mining rig has multiple graphics cards installed that are usually connected to one or more powerful motherboards and PSUs. The mining rig has no covers so that the heat can dissipate in the air as fast as possible.
How to Choose a GPU for Mining?
There are different criteria for selecting a graphics card for mining. The first and foremost thing is the hash rate. The higher the hash rate, the faster the mining process will be. As a result, you will get more profit by mining. Usually, graphics cards with powerful processing units have more hash rates.
The second feature for choosing a GPU for mining is its VRAM and bandwidth. VRAM is mostly in GBs (gigabytes), and the GBs means it has more capacity for storing data before and after processing when mining. Hence, we recommend you install multiple graphics cards with more VRAM, such as 8GB.
But having multiple graphics cards with less VRAM, such as 4 GB, is also OK. It only depends on the scale on which you are mining the data or cryptocurrency. The bandwidth or memory BUS of a VRAM defines the speed of your graphics card. If it is 128-bit or more, your graphics card is faster than the GPU with 64-bit.
The cost of a graphics card is another factor you must consider when choosing a graphics card for mining. A new GPU with more VRAM and cores is costly compared to the others. It would be more expensive when you buy multiple graphics cards. In contrast, second-hand graphics cards are a bit cheaper.
After this comes the total power consumption of a graphics card. If your GPU consumes more power, you will have to pay more electricity bills from the profit you earned from your mining business. The cost increases dramatically when using multiple GPUs and power supplies, especially in a mining rig.
In the end, comes the performance of your GPU when mining. There are two methods for increasing the performance and efficiency of your mining setup. Firstly, buy more powerful GPUs with larger amounts of VRAM. Secondly, purchase multiple graphics cards that collectively work as a team when mining using GPUs.
How Do GPUs Help in Cryptocurrency Mining?
GPUs are better than CPUs or processors because they have hundreds or even thousands of cores compared to the CPUs. Graphics cards also use a fast technique called parallel processing. They also have a more efficient memory called VRAM. That is why GPUs are more powerful than CPUs in mining.
Nearly all professional miners use two or more graphics cards with more VRAM for mining. The clock speed of graphics cards is also way more than the average computer processor. It is claimed that there are GPUs 800 times faster than CPUs. These factors increase the mining speed and the profit overall.
Most computer system motherboards cannot install a single CPU. But you can install multiple graphics cards to a single motherboard, and it is also a professional method for mining data or digital currency. But remember that more GPUs will require more power, and you’ll have to install PSUs.
GPUs are an essential part of cryptocurrency mining. They help increase the speed and efficiency of mining. GPUs have more cores, faster clock speeds, and more VRAM, which gives them the computing power to process transaction data quickly. That is why VRAM is also an important factor in mining.
