Laptop RAM
Hey everyone, I need a bit of clarification. I own a Legion 5 (2022) laptop that came with Samsung 1Rx16 2x8GB modules. I intend to upgrade it to 32GB (2x16GB), but I’m not very familiar with laptop RAM specs—especially the "rank" terminology. I assume "R" stands for Rank? My main concerns are: 1) Which option offers better performance, 2) Are there other ranks beyond the two I mentioned, and 3) Can I check this information physically without looking at the spec sheet or stick label? If you have the laptop’s spec sheet handy, that would help.
The value before R indicates the rank count, while the number after shows the width of each memory chip. 1Rx8 offers better performance by a mile compared to single rank configurations. 1Rx16 provides more value than single rank and often matches expected results. For consumer devices, 2Rx8 is available, and some DDR2 models included 2Rx16 RAM, though these are less common now. Aim for 2Rx8, followed by 1Rx8, then 1Rx16 if possible. When checking online listings, verify the exact model on the product page rather than relying solely on images. This approach ensures accuracy when purchasing. Opt for 2Rx8 first, then 1Rx8, and finally 1Rx16. If you're considering 16GB DIMMs, they won't be available in 1Rx16 form in DDR4; similarly, 32GB DIMMs are guaranteed to be 2Rx8 due to current technology limitations. EDIT: This applies to both desktop and laptop RAM, with laptops using smaller modules. Updated March 28, 2023 by RONOTHAN##
Thanks for your prompt response. Based on what you shared, you seem confident about your purchase. The 16GB stick should feel secure, especially since it matches your expectations. The Samsung OEM label at the marketplace is likely a genuine product, but keep in mind the seller might not have full details. Prices here are typically higher than trusted brands like Crucial or Kingston. Buying in person isn’t practical for you either, as stores rarely take the time to show items to potential buyers. The sealed packaging adds to the concern. You didn’t mention buying kits, so that’s clear. Apologies if this came across as a simple question—I haven’t replaced RAM before and prefer to be cautious.
Yes, I didn't realize the sticker mentioned DDR5 initially. DDR5 doesn't really improve with dual rank, especially compared to DDR4, and current DDR5 memory chips typically offer a 16GB module as 1Rx8. It's usually not advisable unless you're purchasing OEM units that match the same model exactly. However, because you're opting for DDR5, Samsung has released only one DDR5 IC at the moment, so buying a Samsung DDR5 will ensure it's identical.
Understood. I'll remember that. Appreciate the input @RONOTHAN##.
