ProBook 455 G7 Vega 7 graphics

[Roman129475]

Hello!  I haven't found a single item in the bios that could be responsible for setting up graphics. how can I increase the amount of RAM allocated for the needs of the Vega 7 integrated graphics?

Hello @Roman129475 
If your model allows you to change this setting, it would be available in the BIOS:
System Configuration → Device Configuration → UMA Frame Buffer
If present, set to a higher value (1GB / 2GB).
But most HP models do not show this setting. Check the manual/support documentation of your model for an exact confirmation.

What you can do to improve iGPU performance

Even though you can’t increase VRAM manually, you CAN optimize performance:

✔ Install dual-channel memory (very important)

Vega gains huge performance improvements from memory bandwidth.

If you currently have one RAM stick, add a second stick of the same size & speed.

→ This alone can improve Vega performance by 20–60%.

✔ Use faster RAM (3200–4266 MHz, depending on model)

Higher memory speed = faster iGPU.

✔ Update BIOS and AMD graphics drivers

This ensures you get the best memory management and stability.

Hope this helps!
