  • easy to install
Style: 2666 MT/s Size: 8GB
Excellent RAM, easy to install and works perfectly. My PC improved markedly in speed and performance. Very good value for money, totally recommended."

  • Three Years In: Still an Excellent Upgrade
Style: 2666 MT/s Size: 16GB
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! ... show more

Woks perfect on my MSI GL65 Leopard, I kept one 8GB ram and with this I got a 40GB ram machine. All good

  • Easy to install; laptop picked up that it was 8 GB right away.
Style: 2666 MT/s Size: 8GB
The package was concerningly small, though it was pretty easy to install. The video for installation didn't come when it was delivered (I'd expected an email to be sent with a video), but I had experience going into my HP 15 laptop before. Just unscrewed 10 of the same screw: 4 on the underside, 2 beneath the detatchable battery, and 4 beneath the rubber pads. Once unscrewed, I slid the disk drive away, and looked for a long rectangle. I pulled the two secure arms to the side and it popped out. I inserted the new ram by clickingnit into place, rescrewed the screws, and powered it back on. I checked the System Information app and sure enough, the physical installed memory went from 4 GB to 8 GB. I wouln't say that it makes booting up some apps faster, but once I'm in them, they seem to run quite well comapred to using 4 GB of RAM. I would certainly recommend Crucial to a friend. Their price was about $8 less than other sellars, so it was certainly worth it. ... show more

  • Perfect!
Style: 2666 MT/s Size: 16GB
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.
