Question 15.4gb usable out of 16gb.

[adrian maravilla]

I saw 15.4gb usable out of 16gb in my pc. (642mb hardware reserved)
5600g
rtx 3060
2x8gb gskill ripjaws v 3200mhz
b450m steel legend..

anyway I can remove the 642mb on my ram? what I see on google is because i'm using a cpu with igpu, but i'm using a discrete gpu.. afaik i've disabled my igpu. still it's 15.4.

before this i'm using a 4770 with 2x8gb ddr3 and msi z97m (all 16gb usable)... is this normal for AMD?

From BIOS, you can define how much RAM is allocated for iGPU.

For increasing/decreasing iGPU VRAM amount, here's a guide (MSI B350 chipset MoBo),

Your BIOS may be different, but general idea remains the same. Just browse around until you find the correct value to change.
