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.

    Alright, I’m a software engineer and PC building hobbyist, so by no means an expert when it comes to this stuff. But I’ve added and replaced so much RAM over the years, that I think I can help you.

    Overall, what you need to know is the DDR version, if they are DIMM or SODIMM, the frequency and the capacity.

    I usually figure out the DDR type by simply looking at whatever was in the machine previously, or checking out the motherboard specs.

    I’ve never encountered other than SODIMM on a laptop. The same cannot be said for a desktop, which can use either depending on the motherboard.

    If you make sure the DIMM type and DDR version matches your motherboard, the stick will fit in your machine.

    For the frequency, I generally try to make sure all sticks run at the same frequency. This can also be tweaked in the BIOS.

    When it comes to capacity, it depends on your needs and budget.

    Good luck with your upgrade!

      This is so helpful, thanks a ton! Without knowing the “how,” I would have been right back here the next time I needed to make an upgrade, so thank you for “teaching me to fish” for RAM so to say.
