Hello there,
Thanks for your reply~
Yes, this is completely correct and normal.
What effect does setting it to 32 GB have?
Setting it to 32 GB for the GPU is almost certainly a bad idea and a massive over-allocation. Here’s the effect:
The Negatives (Why 32 GB is problematic):
Wasted System RAM: Your integrated GPU will now reserve 32 GB of your 64 GB system RAM from the moment you boot your PC. This memory is taken away from Windows and your applications, even if the iGPU is only using 2 GB. You’ve effectively reduced your available system RAM to 32 GB for everything else.
No Performance Benefit: An iGPU’s performance is limited by its graphics cores (compute units), memory bandwidth (which is much slower than dedicated GDDR), and thermal limits. It will never come close to needing 32 GB of VRAM for any game or application it’s capable of running. Even high-end dedicated GPUs with vastly more power often come with 12-24 GB.
Potential for Instability: Allocating such a huge chunk can sometimes cause system instability or boot issues, as it leaves less memory for essential Windows processes.
The Intended Purpose & Proper Configuration:
How it Works: When you set this to, say, 4 GB, your system reserves that 4 GB for the iGPU. If a game needs more than 4 GB of VRAM, the iGPU can dynamically borrow more from the remaining system RAM (this is slower). The setting acts as a “minimum reserved” and “maximum allowed” pool.
Recommended Setting:
For general use and light gaming: 2 GB is often sufficient.
For 1080p gaming on an iGPU: 4 GB is a common and safe sweet spot.
For very high-resolution textures or specific professional apps that might benefit: 8 GB is the absolute maximum you should consider, and only if you have 64 GB of total RAM.
32 GB is never a sensible value for an iGPU.
3.Your system is working as designed for the software you’re using. Your NPU will remain idle until you run an application that is specifically coded to take advantage of it.
Have a nice day~
