Hello, now I am update to BIOS 3.60 and I want to adjust the share memory again.
But now I cannot remember the path for modification, could anyone please let me know?
I own B450M Pro4 and use 2400G.
I want to get at least 4GB

Thank you.

Dear Titigresse,

Greetings, this is ASRock TSD.

Regarding your question about share memory, kindly adjust the following settings:
1. Go to Boot\CSM\Disabled
2. [F10] save the changes
3. Go to Onboard Devices Configuration\UMA Frame buffer Size\4GB.

Thanks!

All the best,
ASRock TSD
