You're looking at upgrading your laptop's memory. First, confirm whether the stick you're considering uses MHz or TeraHertz (Tbps) — MHz refers to gigahertz, while Tbps is terabytes per second. The 4GB stick with 2133MHz means it's likely around 2400MHz (2.43GHz), which is standard for DDR4 memory. Check your current RAM specs to see if the new stick matches or exceeds them. Regarding density, it describes how much data can fit in a single chip — higher density means more memory in less space.
I'm not sure about this, but some motherboards reduce clock speed when the memory frequency is too high to match the other component. If it's too low, they'll also slow down the other part and run slower overall. I wouldn't risk it and should opt for a 4GB 2133Mhz stick that matches the laptop's specifications exactly.
I know I shouldn't purchase another one, but my budget is tight.
