How do I decrease my shared RAM?

ExperiencersInternational · August 21, 2021

Hi there, I'd like to know how I could decrease the RAM that is shared with my iGPU and dGPU. Right now there is 4GB shared and I don't need it to be that high, especially since I have a dedicated GPU in my laptop. I'm looking to decrease it down to 2GB (iGPU tends to stay around 0.4GB vRAM usage, and GPU doesn't really go over its 3GB dedicated)

Specs: Acer Nitro 5 AN515-54 (8GB RAM, 4GB shared RAM, GTX 1050 3GB, Intel UHD 630, i5-9300H)

Thanks in advance

You should be able to change the allocated ram in the laptops bios, or simply turn the 630 off entirely and let the 1050 handle everything.

I don't think I can do that since the display is tied to the iGPU

Is there any tutorial that would tell me where to look in the UEFI?

Thats just for PhysX, you should be able to change that easily.

I cant really help with the bios tho, sorry, i think some bios dont have these options… for intel iGpu there might be an option for this in windows or the intel driver however .

Also my advise would be, dont change it, its "shared" as you said its only using ~0.4GB, the rest is free to use for the system. Changing this has basically only downsides and no real upsides. Good luck in any case.
