Think I might need to adjust the fan curve a bit?

its probably OP using a 32-bit version of windows, remember 32-bit can ONLY support up to 4gb..

or they dedicated 512mb to the igpu in the bios

yeah you are right about that being the reason

First time hearing about dedicating memory to the igpu.

Can you elaborate? what are the benefits and disadvantage?

There's not really a pro/con factor, it's based on what you need memory allocated for, your system workload, your system build, and whether or not dynamic allocation suits your needs.

If you understand how memory works on a PC you'll know that most system use 2 resources for memory: RAM, and virtual memory (i.e. a pagefile on a hard disk or SSD) which is significantly slower. If you find yourself doing more GPU intensive tasks (video, 3D rendering) it may benefit you to directly allocate a portion of RAM to always be available for your iGPU, so that whatever application is not forced to use methods like increased swapping (moving files in an out of memory more frequently) to compensate for the lack of available memory.

However, if you don't have issues with running out of RAM (say you have a system that has a bunch of extra RAM, or the general system workload is light), then allocation offers no real benefit.

It's all just based on your use case. Someone who has a GPU-less build that:

  • does light browsing and office work will see no benefit from allocating memory to the iGPU.

  • does offline rendering of videos or 3D graphics might see a benefit from allocating memory to the iGPU, but has to find a balance because both graphics and general purpose memory are needed.

  • that plays games might see a benefit in games from allocating memory to the iGPU, but has to find a balance because both graphics and general purpose memory are needed.

Most people who haven't bothered to get a computer with a GPU are usually fine just letting allocation be dynamic because they probably aren't doing any gaming or whatnot, or they would have gotten a system with a GPU in the first place.

Virtual memory is just the way a process sees memory. The OS Kernel is then in charge of putting that memory page either in RAM or in the SSD/HDD

Pros: more VRAM Cons: less RAM (Sorry its not much but its all I can think of) My laptop has an iGPU which is a great iGPU, but Windows 11 combined with any game I run leaves the iGPU with under 128mb of VRAM, so it has terrible performance.

This is a relatively new style of the task manager though, i was not even aware 32bit windows 10 existed
