Low cost upgrade to keep your laptop modern
My struggling laggy laptop is now back to zipping around again. Quick, easy upgrade. Works great despite being a used item, computer recognized the memory upgrade, computer is stable with no weird crashes after the upgrade, and all is good.

Works flawlessly as upgrade from 4GB to 8GB.
Purchased two 8GB SODIMM memory modules for HP 15 Laptop based on recommendations from both HP and Crucial that a memory upgrade from 4GB to 16GB was available for this model. On opening the case I found only one memory socket had been soldered to the motherboard. Returned the second memory module for refund, but had to pay ~$3.50 postage, otherwise I'd have given 5 stars for "Value for money". The upgrade from 4GB to 8GB solved the problem of slow response time from the computer that plagued it since it was new. SystemInfo.exe reports only 8024MB "Total Physical Memory", instead of the 8192MB expected, otherwise I'd give 5 stars for overall rating.

Good choice for lenovo legion y530!
Works perfectly with my Lenovo Legion Y530. I had a samsung 8gb ram already but it wasn't enough, only 4 gb of ram was available for actual use but after installing another 8 gigs it performs very well as per my usage. Easy to install, watch some YT tutorial. Android studio works better than before. As for gaming it does improve fps slightly, not all games are ram hungry. Multitasking is FLAWLESS, i can ezly switch between heavy games and chrome without waiting for a second. It is budget friendly and definitely worth the money!

Perfect add-on for my Synology DS220+
Installed this 8GB RAM in my DS220+ and the DSM immediately recognised the memory (to a total of 10 GB). Perfect alternative if you intend to increase your Synology RAM as the price is so much cheaper than the official memory chips. Disclaimer: I have only used it on DS220+ and it works. You may wish to experiment it on other Synology models.

FUNCIONAN PERFECTO
Crucial 2x8GB DDR4-2666. Instaladas en un portátil HP Laptop 15-db1xxx. Funcionan perfectamente pero, aunque el CPUIDZ dice que efectivamente pueden llegar a 2666Mhz (1333Mhz x 2), Windows informa de que están trabajando a 2400MHz. CPUIDZ muestra varias combinaciones de timings posibles que la tarjeta de memoria informa que soporta, y que normalmente se pueden seleccionar desde la BIOS del PC, pero la BIOS del portátil HP está muy capada y no se puede configurar nada de eso. Las originales que tenía el portátil indicaban lo mismo en Windows y al sacarlas indicaban que también eran de 2666MHz, mismo fabricante de los chips, Micron.

Works great with my Synology NAS DS720+ !
After struggling a bit to find a suitable memory for my Synology NAS DS720+ someone recommended me to get this memory. Was very simple to install and my NAS identified the memory straight aways, booted up without issues and has been working well with the latest DSM 7.X versions. Considering that the official Synology Memory is quite expensive and hard to get, this one is a steal and performs great. Highly recommended. June 2022
