Considering an Upgrade to My Laptop’s RAM: What Is the Actual Functioning of Shared Video Memory?

Understanding Shared Video RAM and How It Affects Your Laptop’s Performance

Are you considering upgrading your laptop’s RAM to improve gaming or overall system performance? If so, you might have questions about how shared video memory works and whether increasing it could make a meaningful difference. Let’s explore these topics using a common setup as an example and provide guidance on optimizing your laptop’s performance.

Current System Overview

Suppose you’re using an Acer Aspire with the following specifications:

• Processor: Intel Core™ i3-1115G4 @ 3.00GHz

• RAM: 12GB total (4GB pre-installed + an additional 8GB upgrade)

• Graphics: Intel UHD Graphics

This configuration allows you to run most modern applications and games smoothly. However, some less optimized or resource-heavy titles like PEAK may still experience performance issues. One potential factor is how your integrated graphics handle video memory.

Understanding Shared Video RAM

Unlike dedicated graphics cards that have their own exclusive VRAM, integrated graphics such as Intel UHD Graphics do not possess dedicated video memory. Instead, they “share” system RAM with the operating system and other applications. This means the graphics processor dynamically allocates a portion of the RAM for rendering tasks.

The amount of shared video memory can often be configured in your system BIOS or UEFI settings. For example, you might see options to allocate 512MB, 1GB, or more for graphics performance. Increasing this allocation allows the integrated GPU to access more memory for rendering, which can improve performance in graphics-intensive tasks or gaming.

Should You Upgrade Shared Video RAM?

Upgrading your system’s shared video RAM usually involves changing settings in the BIOS or UEFI firmware, rather than physically installing additional hardware. Before you proceed, consider the following:

1. Current Allocation: Check how much memory is currently allocated to the GPU. You can do this in your system’s BIOS or through system information tools within Windows.

2. Impact of Increasing Share: Allocating more RAM to the integrated GPU can improve graphics performance. However, it also reduces the amount of RAM available for other applications and the operating system, which may impact overall performance if you’re low on memory.

3. System Limitations: Some manufacturers lock BIOS settings or limit the maximum shareable memory. Review your laptop’s documentation or contact support to understand your options.

4. Hardware Upgrades: If your goal is significant performance improvements, consider upgrading your RAM capacity beyond increasing shared
