3 Things to Know About Adding an 8GB vs. 16GB RAM Stick
16GB total is enough for almost everything For everyday use like browsing, Office, and light coding, 16GB is fine. You only need 24GB if you regularly hit swap with video editing or multiple VMs.
Warranty is identical for either option Adding an 8GB or 16GB stick does not void your warranty. The soldered 8GB stays untouched either way.
Save the money unless you know you need 24GB The only reason to buy the 16GB stick is if you are certain you need 24GB. Most people do not, so spend the $20-30 savings on something else.
