Dear Serkeril,

Greetings, this is ASRock TSD.

Due to onboard graphics or hardware will reserve some memory sizes, so it will show less than 32GB.

If you would like to have most of the memory size, please adjust the BIOS settings below:
Advanced\Onboard Devices Configuration\UMA Frame buffer size\512M or less.

Make sure to press [F10] to save the changes.

Thanks!

All the best,
ASRock TSD
