I recently purchased a new Lenovo laptop with a Ryzen 7 5700U processor. The laptop runs fantastic with Linux Mint 20.

The laptop has 12GB (4GB soldered + 8GB SO-DIMM). Since RAM is pretty cheap right now, I can get a 32GB DDR4 3200 stick for $110. A 16GB stick is $60.

My question, since the laptop is already mixing RAM sizes, would having 32GB + 4GB any worse than 8GB + 4GB?

Thanks.

Here is a dmidecode from my laptop.

Code:
# dmidecode 3.2
Getting SMBIOS data from sysfs.
SMBIOS 3.3.0 present.
# SMBIOS implementations newer than version 3.2.0 are not
# fully supported by this version of dmidecode.

Are you using all the ram now?
If not then adding more ram won't do much.

No, I am just using the laptop for surfing the web and checking email right now. I might use it for more rigorous duties later on. I typically stay under 4GB.

I am debating on running some other distros in Virtualbox.
