Three Years In: Still an Excellent Upgrade
I've had this installed for just over three years on my ASUS Vivobook 17 X12DA. Performance was increased right away after install, with no troubles. This quality performance has yet to subside so long as I keep my drive maintained. I've had zero crashes or errors/bugs related to it. It was a piece of cake to install: unscrew bottom plates, remove old unit, install new (remember they're secured by clips on the side). It took me less than 10 minutes and why it's so easy to use. The memory quality has been excellent, very nice and smooth all around. Would definitely buy again!

Quality RAM upgrade
Worked perfectly in my HP All in one computer. I was able to double the RAM and the PC is working so much better.

Perfect!
Installed on Dell Inspiron 5590 to increase the memory and worked like a charm! Had no issues and was easy to install. No errors or stability issues with the laptop after the upgrade either.

Great value... M uch needed speedup for my laptop
The RAM was as promised: DDR4 SODIMM 16GB per stick. It took a total of 10 minutes to install and reboot. It passed the MEMCHECK utility with no errors. I ran the memcheck 3 times. If there is a bad memory spot on a chip, that series of checks should have caught it. My laptop now boots up in 4 seconds, ready to work. (I also upgraded to an excellent SSD SASA hard drive [Samsung]) I'm very happy. This laptop was taking 20 minutes to be work ready with the old slow memory and hard drive. The slow boot is a known problem for Windows 10 if you have the old, spinning SATA HDDs.

Excelente escolha!
Comprei um memória de 16GB para expandir a memória total do meu laptop pra 24GB. Fiz uma pesquisa extensa antes para saber quais as melhores marcas de memória RAM, e a Crucial foi uma das principais recomendações. Tem três semanas que meu laptop está rodando com a memória nova, e consigo usar máquina virtual, rodar programas da Adobe e jogar jogos tranquilamente. Super recomendo! A instalação no slot foi bem simples de fazer, porém encontrei um problema com o Windows, que se recusava a incializar após eu inserir a memória nova. Fui descobrir que era uma reclamação de paridade do próprio Windows mesmo, pois os slots de RAM do meu laptop estavam com 16 x 8, e o recomendado é sempre ser duas memórias de capacidades iguals, 8x8, 16x16, etc. Após configurar o Windows para aceitar a configuração 16x8, ele inicializou normalmente, e desde então, não tive mais problemas.

Perfektes Upgrade für mein Synology NAS DS224+
Habe den RAM als Erweiterung für mein Synology DS224+ gekauft – wurde sofort erkannt und läuft absolut stabil. Der Einbau war unkompliziert und in wenigen Minuten erledigt. Seit dem Upgrade läuft das NAS spürbar flüssiger, gerade bei mehreren gleichzeitig laufenden Diensten. Gute Qualität, fairer Preis und zuverlässige Leistung – genau das, was man sich von Crucial erwartet. Klare Kaufempfehlung für alle, die ihr NAS aufrüsten möchten!

Very good product
I've bought this Crucial 16 Gb RAM to upgrade my Lenovo L340 15 API that was really slow with the original 8 Mb. It works like a charm now! It was easy to install. 13 screws to remove, pry out the back cover, pull the old card out and push the new one in, put back the cover & the screws; that's all. No setting to change. Windows 10 and the Lenovo BIOS adjusted to the new SODIM card immediately. I just wish that the envelope be much more smaller - it was huge for such a small item. A real waste of plastic material...

Good product, worked just fine
Snapped into the slot in a second. Worked perfectly. I purchased 16GB RAM to replace my 4GB RAM that came with the laptop. This was my 2nd purchase to bring it up to 32GB. Made my laptop more responsive. Good product.
