    • Easy Upgrade for Dell Inspiron 15 3511 & Immediate Noticeable Improvement
Style: 2666 MT/s Size: 8GB
Review Image by Marci Gann
This RAM stick was a perfect fit for my laptop. Installation was easy, although I am fairly comfortable with computers and basic IT-related tasks. I have a Dell Inspiron 15 3511 that originally came with 8 GB of RAM. I watched two YouTube videos on how to install an 8 GB DDR4 2666 RAM stick and went from there. The entire process was simple, and I had my laptop back up and running in less than 10 minutes. The new RAM was recognized immediately, with no errors or issues. Before installing it, my memory usage frequently reached 100%, and my laptop would start relying on the SSD just from opening Google Chrome. Now, with Chrome open while I write this review, memory usage is around 50% and SSD usage is at 0%. My laptop is noticeably faster and handles multitasking much better. Definitely a worthwhile upgrade! Also, a much cheaper DIY project that was so simple and at a better cost than going to a computer repair store for them to do such a simple task and charge you for the labor. ... show more

    • Easy installation and works great!
Style: 2666 MT/s Size: 8GB
This is just what I needed for my Dell laptop. No compatibility issues and easy install. The price point and fast delivery was a blessing when I was in a bind! Make sure you know your device’s proper specs before ordering.

    • Fantastic NAS memory upgrade
Style: 2666 MT/s Size: 8GB
I upgraded the memory in my Synology NAS with this to triple the amount of memory available to the system. It was easy to install and directly compatible. The price was good as well. Once installed, the NAS is very noticeably speedier as it now has much more headroom to have a bigger file cache and such. ... show more

    • 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

    • Great Product
Style: 2666 MT/s Size: 8GB
Received the stick of RAM as advertised, plugged it into the M70 Think Centre and it booted up and recognized at full speed 2666 MHz no problem. Any stability problems and I'll update this review but so far so good.
