Edit Shared RAM / VRAM Arc igpu Thinkpad

[VITAS]

Hi,

it seems theres no setting in Thinkpad T16 G3 Bios for the amount of vram allocated.
I want to increase the amount for VM use. 
Lenovo SUpport stated that theres no way in their bios to set this.

My Questions are:

- Is there a way (from Fedora Linux) or with the use of a tool to change the setting?
- How can i see the amount of VRAM allocated (Virtualbox shows 256mb max)?
- Is there a percentage of main memory or a fixed value allocated?
- Whats that value or ratio?

My system has 128GB of RAM and an 155h CPU (I know its outside of max RAM supported specs).

thank you for your Help.

Hi, VITAS.

Thank you for posting in our Community. I understand that you have a laptop. Since this is an OEM (Thinkpad T16 G3) original equipment manufacturer device, please take into consideration that our support may be limited since we are not familiar with the technology, settings, customizations, custom drivers, and features that the OEM has designed and installed your system, nevertheless, I will do my best to assist you with your concern. I see your question and I'll get back to you as soon as possible.

Have a nice day!

Hello, VITAS.

To address your question about increasing the Dedicated Video Memory (VRAM) for Intel Graphics, here is some important information:

1. Presetting VRAM: There is no way to preset your VRAM to a specific value. The Graphics Processing Unit (GPU) does not have dedicated memory; it uses shared memory that is allocated automatically based on various factors.
2. Adjusting Maximum Memory: You can limit the maximum memory that the GPU can take. This option is usually available in the BIOS, but it may not be available for all systems. The setting is typically listed under VRAM or Dynamic Video Memory Technology (DVMT).
3. BIOS Settings: The settings values can typically be adjusted to 128 MB, 256 MB, and maximum DVMT. The availability of these settings depends on the motherboard manufacturer and the amount of RAM installed on your computer. We recommend checking with your motherboard manufacturer for more information about the BIOS and the availability of these settings.
4. Fedora Project Community: For systems running Fedora, it would be best to contact The Fedora Project community to check if they have tools to adjust the VRAM of your system.

Additionally, I will close this inquiry now. If you need further assistance, please submit a new question as this thread will no longer be monitored.
