ASUS ROG Zephyrus M16 GU603ZW_GU603ZW RAM Question

[ATLEye]

I am looking to upgrade my ram (I have the base 16 GB), and am unsure what to buy.  I'm having trouble finding out how much ram I can add and what type and speed.  I've seen people mention up to 64GB (32GBX2) of DDR5 5600 and others stating a max of 48 GB and DDR4 4800.  What can I actually add, and do you have a preferred brand?

The GU603ZW has only one replaceable memory slot, and the maximum supported capacity for a single slot is 32GB DDR5 (4800MHz). Thank you.

It may be caused by memory compatibility issues.
It is recommend trying memory modules from a different brand for further testing.
Thank you.
