Good Upgrade or Replacement
Great replacement for a bad SODIMM or a memory upgrade for your laptop. These installed easily and memory tests proved they were reliable. These were used in an HP 15dw laptop and hav proven to work well. A great buy.

Manufactured +3yrs ago?
Memtest86 said it passed all of the tests. What I found interesting, is that MemTest86 identified this 4GB memory stick as being "Kingston" brand and being manufactured on the 10th week of 2022, despite me purchasing it in Jan 2026... Seems to be working fine in my NUC, though.

Great upgrades for you Laptop
I had an old gaming laptop, it runs fine. The only problem is that it only has a 8GB ram, it could run most of the Steam games but often crash if there is too many things going on. Did some research and got this 16GB ram, the price seem fair and other reviews were mostly positive. The installation was easy. Take it out of the container, pop in the socket, reboot your laptop and you'll see the updated RAM. If you have an laptop and wish to give it a little upgrade and don't want to invest a crazy amount of money, this is a great option. But DO YOUR RESEARCH before buying, it may not fit your computer, due to the DDR Generation that your computer supports.

works
memory worked on me HP 15-bs212wm I tried to use 32gb and 16gb memories and they didn't work because my laptop is only compatible up to 8gb, previously I had a 4GB one and the performance was very low, with this new 8GB memory the speed improved considerably, I was thinking of throwing away the laptop but now with the new 8GB memory I am giving it a new opportunity
