Knowing how much VRAM your graphics card has is incredibly important for modern gaming. Most need a certain amount to run at all, and if you want to optimize your game performance and visuals, you need to know how much VRAM you're working with. Many games have VRAM use bars within their settings menu, so you can often see how much you have in there.

If your game doesn't show you that, or you just want to know right now without booting up any games, here are some other ways to find out how much VRAM your GPU has.

Check the labels

If your graphics card is relatively new, just reach for the box. Graphics card memory is so important for modern graphics cards, that the quantity and generation of it is almost always listed on the box in some capacity. It could be the marketing stickers or the spec table on the back, but either or both should tell you how much VRAM your graphics card has.

Alternatively, look on the card itself. Most graphics cards have a model number sticker somewhere on the back that typically includes the quantity of RAM it has on board. The manufacturer's website will also have a full specs table with all the information you need, as should the online store you bought it from (if applicable).

Check your VRAM using DXDiag

The DirectX Diagnostic Tool, or DxDiag, is an iconic Windows tool used to test the DirectX API's functionality in Windows, as well as troubleshoot video and sound issues. It's been part of Windows for many generations, but it still has its uses — like checking your VRAM.

Step 1: Search for "DxDiag" in the Windows search box and select the corresponding result.

Step 2: Wait a minute or so for the diagnostic tool to complete, then select your main display from the tabs at the top of the window. In most cases, this will be Display 1.

Step 3: Under the Device heading you should see information about your graphics card model. Next to Display Memory it should tell you your VRAM total in Megabytes. You can round that to the nearest 1,000 for the colloquial understanding of VRAM.

In this example, the Nvidia RTX 3070 Ti is listed as having 8031MB of Display Memory. That equates to 8GB, as per the model's specifications.

For more information on your graphics card, you can use an in-depth third-party tool like HWInfo. That one is particularly good for checking your CPU temperature, too.

How to use AMD Smart Access Memory and Nvidia Resizable BAR
Lisa Su, the CEO of AMD, pictured holding an AMD Radeon RX 6900 XT graphics card.

We recently covered the technical background of Nvidia’s Resizable BAR (Base Address Register) and AMD’s Smart Access Memory, so now it’s time to dig in and explain how you use these technologies.

Although they achieve the same sort of goal of giving the CPU far greater access to game assets for faster allocation, the process for enabling these technologies is slightly different. Let's go over the AMD method and the Nvidia method, along with what you should know.

Knowing how much random-access memory, or RAM, that your PC has is important for a number of reasons. First, you want to be sure you have enough RAM for your needs. Second, you might want to install a particular application that has a specific recommendation for the amount of RAM it needs to run smoothly.

The great thing is that it's extremely easy to find out how much RAM your PC has without cracking open the case. Here's how.

How to repaste your graphics card
Installing a graphics card in a motherboard.

Getting a new graphics card for its MSRP in 2022 is nearly impossible, so it's more important than ever to take care of your current GPU. Sure, a nice dusting with an overpriced can of compressed air works, but there's more you can do: Repaste it.

Replacing the thermal interface material, or thermal paste, on your graphics card can lower temperatures, reduce noise levels, and improve performance, and in the case of old cards where the original paste has dried out, extend its lifespan considerably.
