I have a Lenovo P15 Gen1 laptop with easily accessible ram slots. I have never purchased parts for a PC or done any upgrades myself. I think I understand the process well enough, but I’m lost in all the RAM types and model numbers. How can I tell which sticks will fit and work with the P15, and where’s the best spot to order them in the US? Thanks for any help with such a basic question.
I’d get CPU-Z and run it on the laptop as it is now. It’ll tell you what type of RAM your machine uses and what voltage it takes. I know with DDR3 there were multiple different voltages for laptop memory, but that may not apply to DDR4. Personally I’d get the largest possible stick I can, two 8G may be faster than one 16G, but if you buy one 16G you can get another 16G later to get to 32, instead of needing to buy two 16G when you want to upgrade.
