Right now I have 8GB of ram on my laptop and 2.1GB is used for hardware reserved. And I found out 2GB is used for my AMD Radeon(TM) RX Vega 10 Graphics memory. So that made my ram only 5.94GB usable. I have GTX1660ti, So I want to use as much ram as possible for the best gaming performance. I tried lookup in bios but there are no graphics settings. I tried the registry editor method. Neither worked. Is there any way to fix this problem or decrease dedicated video memory besides upgrading my ram. I want that to be my last option. Thank you.
It is normal for your IGPU to use 2GB of RAM. If it uses 1GB of RAM, VRAM will not be enough for new games. GPU VRAM setting may be within the BIOS. Refer to the BIOS settings or motherboard manual. But no need any changes.
I forgot to mention that I have gtx1660ti on my laptop. So I want to be able to use as much ram as possible for better gaming performance.
Can you post the exact Make & Model of your Laptop?
Normally in a Desktop BIOS you can adjust the amount of RAM Memory that can be dedicated to the APU integrated Graphics. Anywhere from less than 1 gbyte to a maximum of 2 gbytes of RAM Memory.
Now as for a Laptop BIOS, I guess depending on the manufacturer, may have that option in BIOS settings (as mentioned by mstfbsrn980) but not really sure if it does or not until I know the Make & Model of your laptop.
For your information on how to update and configure your Switchable Laptop from AMD Forum:

Here is where you can update all your Asus laptop drivers from Asus Support: ROG Zephyrus G GA502 Driver & Tools | Laptops | ASUS USA
I would suggest to update your Nvidia and AMD graphics drivers and CHIPSET (which includes the AMD Graphics driver) and also to be sure you have the latest BIOS version installed (Version 208).
I downloaded the manual from Asus for your laptop and it is not very helpful as to the various BIOS settings or anything to do with the laptop's graphics in general.
Seems like your best bet is to upgrade the laptop's RAM MEMORY but before you do that I would suggest to open a Asus Live Chat or open an Asus Support Ticket and see what they recommend.
Looking at your Asus Features from Asus.com you have a program called ROG Armoury Crate where you can configure your GPU and CPU performance: https://www.asus.com/us/Laptops/ROG-Zephyrus-G-GA502/Features/
Hey there! I've got MSI Alpha 15 with VEGA10 and had the same problem. This is how I fixed it.
Your BIOS could be a bit different but the names of those settings should be similar. I wouldn't recommend you to low it down to 256, but it's up to you to experiment.
