Hiya guys,

I’ve just enabled Integrated Graphics from BIOS for an additional monitor to use (HDMI to Motherboard), and I’m wondering what I should set the DVMT Pre-Allocated Memory to? It’s currently set to 1024 MB from the BIOS settings, but there’s an option to lower it all the way down to 64MB or in between 64 - 1024 MB.

What does this mean precisely, and how will this affect performance?

I have 32GB RAM, Core I9 9th Gen CPU, and a dedicated GPU. I’ve heard several mixed stories regarding this, but I’m quite confused by it. I’m hoping some community members can shed some light on this matter.

Cheers!

    Not sure what DVMT is, but because it’s an iGPU, it already uses ram as vram (For a dGPU, vram can matter because if it needs more than you have, it’ll be forced to use ram as vram, which is usually slower, which isn’t the case here), it’ll just allocate more if needed, so setting more won’t help.

    Doesn’t matter, it just reserves the RAM so older software won’t complain about the lack of “VRAM”. Set it to the lowest, when it needs more it’ll allocate more.
