You can’t add physical VRAM to an existing graphics card through Windows or by changing a setting. To get more dedicated VRAM, you need a compatible graphics card with more onboard memory. If your PC uses integrated graphics, some systems let you adjust how much system RAM graphics can use—but that changes memory allocation, not the hardware, and it may not improve performance.
First, find out whether your PC has integrated or discrete graphics
A discrete graphics card has its own onboard memory, commonly called dedicated VRAM. Integrated graphics use system RAM instead. The distinction matters because the available settings—and what changing them can accomplish—are different.
In Windows, open Settings > System > Display > Advanced display, then select Display adapter properties. The adapter name and memory figures can help identify the graphics hardware. You can also check the PC or graphics-card specifications from its manufacturer. Windows’ reported shared-memory limit is not necessarily RAM permanently set aside for graphics; Intel explains that it is not an ongoing reservation. Intel’s explanation of graphics memory in Windows 10 and Windows 11 describes how integrated graphics use system memory.
What the memory labels mean
- Dedicated video memory: Memory physically installed on a discrete graphics card. Changing a Windows number does not add to it.
- Shared system memory: System RAM that integrated graphics may use. The reported maximum is an available limit, not necessarily a permanent reservation.
- UMA frame buffer: A portion of system RAM reserved for integrated graphics on supported systems. The setting is typically managed in firmware.
Can you increase dedicated VRAM?
No setting can add memory chips to an existing discrete GPU. NVIDIA’s older hardware guidance makes the distinction clearly: “You cannot add VRAM to your GPU.” Its document concerns Adobe video workflows, so treat it as a hardware explanation—not a promise that a card with more memory will make every game or application faster.

If a workload genuinely needs more dedicated memory, the hardware option is to replace the graphics card with a compatible model that has more onboard VRAM. Check the card’s physical dimensions, power requirements, PC compatibility, workload fit, and budget—not just its memory capacity. The sources do not establish a universal minimum VRAM requirement or guarantee a performance gain from upgrading.
When changing graphics memory allocation may help
On some integrated-graphics PCs, a firmware setting or a platform-specific software control changes the amount of system RAM reserved or made available to graphics. This can affect how an application detects available graphics memory, but it does not create dedicated GPU memory. Allocating more RAM to graphics also leaves less available to the CPU or other applications.

AMD says the UMA frame buffer size on desktop systems with integrated graphics is usually set to Auto and does not need adjusting. Keep the automatic setting unless a supported application has a specific memory-detection problem and your PC maker documents a setting that applies to your system.

Ways to change the setting on supported systems
Desktop PCs with AMD integrated graphics: UMA Frame Buffer Size
AMD documents this procedure for supported desktop systems with integrated graphics. BIOS menus vary by motherboard, and the option may not be available on every PC.

- Powered by the NVIDIA Blackwell architecture and DLSS 4. System Requirements: Minimum 850W PSU with 16-pin 12V-2x6 (12VHPWR) connector required. Verify before purchasing.
- Military-grade components deliver rock-solid power and longer lifespan for ultimate durability. Compatibility: 348mm (13.7") length, 3.6 slots, 4.3 lbs. Confirm case clearance and slot spacing. GPU bracket included.
- Protective PCB coating helps protect against short circuits caused by moisture, dust, or debris
- 3.6-slot design with massive fin array optimized for airflow from three Axial-tech fans
- Phase-change GPU thermal pad helps ensure optimal thermal performance and longevity, outlasting traditional thermal paste for graphics cards under heavy loads
- Restart the PC and enter the BIOS or UEFI setup. The key to press during startup depends on the manufacturer.
- Find UMA Frame Buffer Size in the firmware settings. The location and available values vary.
- Choose a listed allocation, save the change, and restart. If you do not have a specific reason to alter it, leave the value on Auto.
AMD’s example says a 1 GB or 2 GB allocation may address some game texture or memory-requirement issues on systems with at least 8 GB of RAM. That is an example for supported desktop integrated graphics, not a general performance fix. AMD warns that assigning 2 GB on a system with only 4 GB of RAM may reduce overall performance.
Intel Core Ultra Series 2 and later: Shared GPU Memory Override
Intel documents a software-based Shared GPU Memory Override for integrated graphics on Core Ultra Series 2 or later. The cited requirements are Intel Graphics Software version 25.26.1602.2 and graphics driver version 32.0.101.6974 or later, with at least 10 GB of system memory. Intel lists a default limit of 57%; the maximum depends on installed system RAM. These requirements and version numbers are from Intel’s support page, last reviewed November 3, 2025, and may change.

For an eligible system, use the override in Intel Graphics Software, change the available memory limit, and restart for the change to take effect. Intel warns that changing the limit may affect system performance. If the option is missing, check the processor, software, and driver requirements rather than assuming Windows can enable it on any PC.
AMD Ryzen AI 300 series and later: Variable Graphics Memory
AMD documents Variable Graphics Memory for Ryzen AI 300 series and later. It reallocates system RAM at the BIOS level; the operating system treats the reallocated portion as dedicated graphics memory, but that RAM is no longer available to the CPU as system memory. A restart is required. AMD describes the feature for particular power-user and AI workloads and warns that incorrect use may hurt system performance. AMD’s Variable Graphics Memory FAQ

Why you may not see a VRAM setting in BIOS
BIOS controls depend on the PC or motherboard maker, graphics hardware, and firmware. Intel notes that a dedicated-memory adjustment may be absent; when offered on supported systems, it is typically a BIOS setting called something like VRAM or DVMT. Even then, users generally set a maximum the integrated GPU may take rather than specifying its exact memory use. Intel’s guidance covers older Windows environments, so its labels should not be treated as a universal current-Windows procedure. Intel’s guidance on adjusting dedicated video memory
Do not confuse IGD Aperture Size with total VRAM. It is a separate, platform-specific setting, and Intel cautions that choosing a large aperture is not always advisable and can affect performance. Intel’s explanation of IGD Aperture Size
Will increasing VRAM make games or apps faster?
Not automatically. A larger allocation may help a supported application that specifically needs more accessible graphics memory, but it can also reduce RAM available for other work. No performance statistic in the cited vendor guidance establishes a general FPS or application-speed improvement from increasing an allocation. If you are trying to solve a particular error or performance problem, identify whether the app is reporting insufficient graphics memory before changing a setting.
Quick Recap
Choose the right fix for your situation
- Discrete GPU and genuinely insufficient dedicated memory: Compare compatible graphics cards with more onboard VRAM for your workload.
- Integrated graphics and a documented game or app memory issue: Check whether your PC supports a relevant firmware or vendor-software option, and follow the PC maker’s instructions.
- Setting absent or PC requirements not met: Do not try to force a BIOS change or use a utility claiming to add physical VRAM. The hardware and platform determine what is possible.
- Memory limit already meets the app’s needs: Increasing it is not evidence of a performance improvement; leave automatic settings alone unless there is a specific reason to change them.
