Changing the VRAM on a Swift GO 14 (7840u) laptop. Is there a way?

ilovetacos

My laptop's VRAM is currently allocated to 2GB.

I want to change this VRAM, but all the methods below have failed. Is there a way?

1. Modifying the BIOS: There's no option I can change.
2. Using the OEM drivers provided by the Acer website: The default setting for the memory optimizer in the Adrenaline app is "Blank." Switching to "Gaming" requires a reboot. After rebooting, no changes are made. (The changes are not applied.)
3. Using the latest Adrenaline app: I installed the 25.9.1 WHQL driver from the AMD website. The default setting for the memory optimizer is "Productivity." Switching to "Gaming" does not apply the changes, as in step 2.

The AMD Ryzen™ 7 7840U's integrated Radeon 780M graphics does not have its own dedicated memory; instead, it uses a portion of the system's main memory (RAM). The amount of RAM allocated to the integrated graphics is determined by settings in the system's BIOS/UEFI. The maximum graphics memory it can use is dependent on the total amount of system RAM installed. See HERE for how to increase the vram also, also your Swift Go 14 has internal soldered LPDDR5 type ram and you can't increase that. Good luck and hope this helps you out.

AMD Ryzen™ 7 7840U Graphics memory allocation

• System dependent: Because the graphics memory is not fixed, the maximum amount available depends on your specific system's hardware configuration. The total amount of system RAM, whether it's DDR5 or LPDDR5X memory, is the limiting factor.
• BIOS/UEFI settings: The amount of shared memory is controlled through a setting in the computer's BIOS or UEFI menu. Users can typically increase the video memory (VRAM) allocated to the integrated GPU to improve graphics performance.
• Example configurations: In practice, a system with 32 GB of RAM might have its BIOS configured to allocate 4 GB, 6 GB, or even 8 GB to the integrated GPU. The more RAM allocated to the integrated GPU, the less is available for the operating system and other applications.
• Impact on performance: Giving the integrated GPU more memory can improve gaming performance, particularly in titles with high VRAM demands. However, the overall performance is also affected by other factors, including RAM speed, which can be up to 7500 MT/s in LPDDR5X systems featuring the Ryzen 7 7840U.
