No, it is not possible to increase the amount of RAM on a graphics card. The RAM on a graphics card is often referred to as “memory” and is part of the video card design. It is not possible to upgrade or add to this memory like most computer RAM that can be added to or upgraded.
When buying a graphics card, the amount of RAM provided by a specific graphics card is usually determined at the time when the card is designed. This means that a particular graphics card may have a certain amount of RAM that is fixed and cannot be increased. Many times RAM (or memory) is built onto a graphics card in order to save space and power.
On the other hand, if you are looking for a graphics card with more memory than what is offered in the cards available on the market currently, you may have some options available. Some of those include researching websites such as Newegg or Amazon to find different graphics cards with more RAM than the ones you are considering. You can also take a look at enthusiast-level models which may offer more RAM than “regular” non-enthusiast graphics cards.
Also, dedicated graphics cards, as opposed to integrated graphics, are often going to offer more RAM than their integrated counterparts. Often with integrated graphics, you will not be able to change, upgrade, or add more RAM to the graphics card due to the design, layout, and cost of the board. When shopping, note the differences between dedicated cards and integrated graphics cards in order to get the best overall performance.
Another option is to invest in two or more video cards and run them in tandem using software such as SLI or Crossfire. This type of setup will allow you to combine the VRAM from both cards to create a larger pool of RAM which can be used for gaming, graphic intensive applications, or workstation tasks. This type of setup requires additional hardware and compatible motherboards and may not be suitable for all users.
So, while it is not possible to increase the amount of RAM on a graphics card, you may still be able to get the performance you need by researching different models with more VRAM or by investing in a multi-card setup.
