VRAM, short for Video Random Access Memory, is a special memory in your computer’s graphics card that helps display images. Having more VRAM improves performance.
Similar to your computer’s central brain (CPU), which uses regular memory (RAM) for programs, the graphics brain (GPU) uses VRAM for images and actions sent to the screen via HDMI.
Think of your computer as having two memory types: one for long-term storage (storage drives) and one for immediate tasks (RAM and VRAM). In essence, VRAM serves as active memory for graphics, enhancing game visuals and task speed.
Discover everything about your computer’s graphics card, including what a VRAM is, its functions, and optimization, in this helpful guide.
🔑Key Takeaways:
- VRAM (Video Random Access Memory) is vital for GPU-intensive gaming and graphic tasks.
- The amount of VRAM directly impacts a graphics card’s performance and image rendering capabilities.
- Different types of VRAM, such as GDDR and MDRAM, have distinct purposes and advantages.
- VRAM is specialized in storing image data, while RAM handles general system tasks.
- To optimize VRAM usage, check its capacity, consider GPU upgrades, or adjust the allocation of VRAM in BIOS.
Delving into the Inner Workings of VRAM
VRAM stores high-speed image data for screen display. It’s crucial for graphics-intensive tasks like gaming and creative work.
The amount of VRAM directly influences your PC’s capability to handle complex images; more VRAM means better rendering.
VRAM is often called GPU memory and affects your graphics card’s performance. Modern GPUs use GDDR6, GDDR5, or GDDR4 VRAM standards.
Let’s delve into the types of VRAM, their impact on gaming and creativity, and how to choose the right amount for your needs.
Types of VRAM
In gaming, VRAM is vital since games demand varying VRAM amounts due to different resolutions. Extra graphics card memory is necessary to render high-quality images. Without it, textures overflow VRAM, leading to GPU spillover into RAM and poor and slow performance.
There is no best type of RAM, as different types have varying applications. Get to know about them below.
1. Window RAM (WRAM)
Samsung Electronics developed a fast type of RAM called WRAM, which is short for Windows RAM and supports two ports.
With this capability, a video adapter can access memory for display while new data is written, leading to quicker display than single-port RAM.
WRAM is akin to VRAM but offers even better performance at a lower cost. It’s due to the support for addressing large blocks (windows) of video mem
Purpose: WRAM is excellent for super sharp pictures such as 1,600 x 1,200 pixels using true colors. However, it’s not connected to Microsoft Windows, though. It is used in the Matrox MGA Millennium video display card and can also be used elsewhere. |
2. Synchronous Graphics RAM (SGRAM)
Imagine a budget-friendly video memory that works well with the computer’s clock. It’s like having two pages open at once in a book.
This memory has 144 pins and connects to your computer at different speeds — 83 MHz, 100 MHz, 125 MHz, and 142 MHz — making it work quickly.
Purpose: SGRAMs are explicitly designed to handle tasks that need lots of graphics power, like smoothly making 3D pictures and playing videos. |
3. Rambus Dynamic RAM (RDRAM)
RDRAM emerged from Rambus in 1999, surpassing older memory types like Synchronous DRAM (SDRAM). While SDRAM handles data transfer at up to 133 MHz, RDRAM achieves up to 800 MHz speeds.
It goes by names like Direct RDRAM or Rambus. It consists of a RAM, a RAM controller, and a bus path connecting it to microprocessors and other PC devices.
RDRAM serves as a high-speed memory subsystem, excelling at data transfer.
4. Multibank Dynamic RAM (MDRAM)
MDRAM is a high-performance memory technology featuring small DRAM banks (32 KB each). It is connected to a shared internal bus through individual I/O ports.
This unique design enables simultaneous read/write operations on multiple banks, resulting in significantly faster performance than regular DRAM.
MDRAMs suit graphic tasks, sync for better performance, and cost less than other VRAMs due to their tailored memory capacity.
5. GDDR (Graphics Double Data Rate) VRAM
Introduced in 2000, GDDR (or GDDR SDRAM) has become the dominant graphics RAM, surpassing VRAM and WRAM.
Newer GDDR generations are faster and improved, but their numbering doesn’t match DDR versions. For instance, GDDR3 uses DDR2 chips, GDDR5 uses DDR3, and so on.
This advanced type of VRAM is meticulously designed for the demanding needs of graphics-intensive applications.

VRAM Optimization Tips
Image source: GamerBTW
Knowing what virtual memory is and how much available space is the first step in improving its performance.
The next step is to outline different methods to optimize VRAM, ensuring smooth graphics processing. The following techniques will be discussed in detail:
Tip #1: Graphics Driver Update
Updates to the graphics driver are vital to using VRAM best. Ensuring your graphics drivers are current improves compatibility, fixes bugs, and boosts speed.
Tip#2: Tweaking the In-Game Graphics Settings
Optimizing the image settings in a game is a crucial part of using VRAM. You can fine-tune VRAM allocation for a more fluid gaming experience by adjusting texture quality, anti-aliasing, and shadow resolution options.
Tip#3: Closing Unnecessary Resource-hungry Apps & Background Processes
Limiting background tasks is a smart way to free up VRAM for graphics, improving overall performance. By dedicating more VRAM to graphics-intensive programs, you ensure better functionality.
Tip#4: Tracking Your VRAM Usage
Keeping an eye on VRAM usage is important for better optimization. Doing this lets you make smart decisions and improve how VRAM is used.
Tip#5: Clearing Out Temporary Files
Removing temporary files is another way to free up VRAM. Temporary files can build up and take up space, affecting VRAM. Regularly cleaning them lets you free up VRAM and ensure it’s used well for graphics tasks.
Determining how much is available in your computer’s system is necessary before optimizing your VRAM.
Knowing your system’s VRAM capacity lays the groundwork for optimizing its usage effectively.
How To Check VRAM
For those uncertain about their VRAM capacity, several methods can help check the amount available.
Here’s how to do it:
- Press Win+R or type dxdiag in the Start menu.
- Launch dxdiag.
- Click on the Display tab.
- Scroll down to find Display Memory (VRAM) under Device reading.
An Nvidia GTX 1070 with 8GB of Display Memory (VRAM) is used in this case.
📝 Note: There are other ways to check how much your VRAM is, such as: Checking the graphics card box. Look up your GPU model on the manufacturer’s website. Looking for the VRAM number in a game’s settings. Using the GPU’s performance overlay. |
How To Increase VRAM
Getting a new or better graphics card is the way to improve your video performance.
Switching to a dedicated graphics card will significantly enhance video quality if your computer uses integrated graphics and runs slowly.
if you can’t upgrade the graphics card, you can increase the dedicated VRAM in two ways.
Method 1: Increase VRAM Allocation in BIOS
Access your computer’s BIOS and find Advanced Features or Graphics Settings options. Look for an option to adjust GPU memory allocation, typically set at 128MB by default. If possible, increase it to 256MB or 512MB.
📝 Note: Not all CPUs or BIOS versions offer this option. If it’s unavailable, consider the workaround below. |
Method 2: Faking VRAM Increase in Windows
For integrated graphics, the Dedicated Video Memory value doesn’t matter; it’s fictional. Modify Registry to change VRAM reported to games, though it won’t increase VRAM.
👍Helpful Article: If you can’t locate your Windows, this article might help you: |
Steps for Faking VRAM Increase in Windows:
- Open Registry Editor (type regedit in Start Menu).
- Navigate to HKEY_LOCAL_MACHINE\Software\Intel.
- Create a new key named GMM.
- Add a DWORD (32-bit) Value called DedicatedSegmentSize.
- Assign a value between 0 to 512 (in megabytes) and restart your computer.
- Check if it improves game performance; try higher values if needed.
These methods might not always work, but it’s worth trying. Add more RAM or free up RAM for integrated graphics issues with limited RAM.
