I bought a very inexpensive laptop from costco.ca. Dead deal: <https://forums.redflagdeals.com/costco-ca-hot-299-99-hp-15-6-touchscreen-laptop-intel-core-i3-1215u-8gb-ram-256gb-ssd-2673529/> Unlike most laptops these days, it has two sockets for RAM. Only one was occupied. It had an 8 GiB stick of RAM. - two stick should perform better: allow dual-channel memory access - many consider 8 GiB too little RAM these days. I'm not sure that's true but more cannot hurt I bought another 8 GiB stick with the same specs from Amazon for $25.99 and installed it. <https://www.amazon.ca/dp/B08P3KJRM5> I ran passmark benchmarking software before and after the upgrade <https://www.passmark.com/baselines/V11/display.php?id=202729010710> <https://www.passmark.com/baselines/V11/display.php?id=202835509345> The Passmark Rating (whatever that is) went up about 20%. You can see that the laptop still has modest performance. I'm glad the HP included one 8 GiB stick instead of two 4 GiB sticks. That made it cheap for me to upgrade (add one stick instead of replacing two) but it made the off-the-shelf performance worse.
