It is known that a video card is an integral part of a computer.
A lot depends on it. For example, the quality of image output on a computer screen. The larger the memory, the better the performance and image quality will be. Regardless of how the user uses the device (plays modern games, processes videos and photos, surfs the Internet or does office work), he needs to know about the size of the video card memory. It must be remembered that the user will not be able to find out the volume until all the necessary drivers for the video card are installed on his computer.
We present to your attention several popular ways to find out the size of video memory, which are suitable for all devices with different operating systems.
What is the difference between GDDR4 and GDDR5?
GDDR5 is the most modern and fastest type of video memory, a radical difference from GDDR4 is the separate clocking of data lines and addresses - addresses are transmitted in DDR mode (Double Data Rate) at the CK frequency, and data is transmitted in DDR mode at the WCK frequency, which two times higher than the first, i.e.

Video card memory for mining - which memory is better and how to determine it?
Experienced miners know that the efficiency of a graphics adapter in mining depends not only on the model. Manufacturers of gpu devices do not produce memory chips, but purchase them from third-party manufacturers. But how can you find out what kind of memory is on a video card if the specifications only indicate its type, for example, GDDR5.
This is quite enough for toys and office work, but not for mining. Memory chips from different manufacturers do not equally withstand the load during overclocking, and the productivity of mining of many cryptocoins directly depends on the memory clock . We will now tell you how to find out the manufacturer of gpu memory.

Information about video memory is available in the Info tab, Mempory Type column.
Search by serial number
A little more about the suppliers. GDDR chips are produced by 4 companies:
- Samsung.
- Hunix.
- Micron.
- Elpida.
Graphics adapters with Samsung . They hold the load well and are the coldest.
Devices with Hunix provide decent hashrate, but are less stable and run hotter.
Micron memory installed do not overclock well and are very hot, however, there are exceptions. Complaints about Elpida , although cards with this memory can outperform both Hyunix and Samsung in terms of hashrate.
Important! In most cases, you can only find out the Mempory Type by inserting the card into your computer; such checks are not carried out in the store. But, the memory supplier of some AMD GPU models is determined by the serial number.
Memory type AMD RX 470, 480, 570, 580
For video cards of these models, manufactured at Sapphire factories, there is a certain pattern between the serial number and the type of memory.
AMD Sapphire RX 470 and RX 480 have serial numbers:
- Hynix: A1630, A1637, A1640, A1648, A1715, A1718, A1721
- Samsung: A1636, A1639, A1644, A1645, A1647, A1650, A1700, A1706
- Elpida: A1637, A1638, A1641, A1643, A1712
- Micron: A1610, A1701, A1702, A1707
AMD Sapphire RX 570/580:
- Hynix: A1714
- Micron: A1718
This rule does not apply to video cards assembled at other factories. But, you can contact the technical support department of the manufacturer whose video card you are planning to buy with a question about the type of memory. Specialists of the Russian department of Sapphire Technology communicate with clients through the social network VKontakte, link https://vk.com/sapphiretechnology.
Conclusion
Navi series video cards come with Samsung memory, at least that’s what everyone who actually tested them says. GDDR5X chips for the GTX 1080 Ti are produced only by Micron. Memory from this supplier can often be found on ASUS cards, but Gigabyte prefers Hunix or Samsung chips. Before purchasing, read reviews about the card on thematic forums.
You cannot be 100% sure that you will come across just such a GDDR manufacturer. However, this does not mean at all that by purchasing a card with Elpid memory for mining, you have signed a death sentence for yourself. Of course, there is a difference in the number of hashes and stability of operation between video cards with different types of memory, but still, it is not so huge that you panic and run back to the store. Problems can arise with any video card and you must learn how to fix them competently and quickly. Happy mining!

What types of video memory are there?
Most modern video card models are equipped with GDDR5 memory. This type of video memory is considered to be the most popular of the subtypes of RAM intended for graphics chips. With its help, the memory frequency of the video adapter can be increased by 4 times, thereby increasing the performance of the device. In addition, there are also cards with DDR3 memory. They are rarely used and are not recommended to be purchased as they are designed to be used as standard RAM for a computer. Most video card manufacturers equip their slow devices with a large amount of memory (up to 4 GB). In fact, video adapters based on DDR3 memory are many times inferior in performance to their competitors with GDDR5 support. For example, a GDDR5 card with 1 GB of memory can outperform a DDR3 card with 4 GB of memory!
Another type of video card involves the use of DDR4 memory, which is not much different from DDR3 memory. True, their performance is slightly better than that of their predecessors.
How to find out the GPU memory manufacturer
There are many coins that use a lot of memory when mining, so it is very important to check the type of memory before purchasing graphics cards for mining.
Everyone knows that Ethhash is a memory-intensive algorithm. AMD RX 470 and AMD RX 570, Rx 580 and 590 are known to mine ETH well, compared to them, Ether and NVIDIA GTX 1070 are also good at mining. However, the hashrate will not be the same for all cards of the GTX 1070, RX 470 series , 570, 580 and 590. Performance varies greatly depending on their memory type. Here we will show you how to determine the memory type of your GPU.
There are several GPU manufacturers: ASUS, Gigabyte, Sapphire, EVGA, MSI, Palit, Zotak and others. However, they do not manufacture the memory chips for their graphics cards; instead, they buy VRAM chips from suppliers who mass produce them.
Some of the most popular GPU memory manufacturers are Samsung, Micron, Elpida and Hynix. Samsung memory cards are known to be better than Micron.

To find out your GPU memory type, follow the instructions below.
Find GPU memory manufacturer by serial number
This only applies to Sapphire RX 470, 480 and MSI Geforce GTX 1070 video cards. Using the serial number out of the box, you can check the memory type of the video card. Or you can call the GPU manufacturer directly and ask for technical assistance to find out the memory type.
Memory type Sapphire GPU RX 470 and RX 480:
Hynix: A1630, A1637, A1640, A1648, A1715, A1718, A1721
Samsung: A1636, A1639, A1644, A1645, A1647, A1650, A1700, A1706
Elpida: A1637, A1638, A1641, A1643, A1712
Micron: A1610, A1701, A1702, A1707
Sapphire RX 500 memory type:
It is well known that GTX 1070 owners, especially those with Micron memory, have serious overclocking problems. Therefore, it is worth checking the memory type before overclocking or intensive use of algorithms.
Instead of going through the above steps, it is better to check with a real source. A Reddit user has shared a table that reveals the memory supplier for MSI 1070 GPUs.
This article will be useful to read, but it will not be useful for GTX 1080 and GTX 1080TI owners, since these cards come with GDDR5X memory, which until now has only been assembled by Micron.
