Excellent Service - Great Product

Product worked as expected. What impressed me the most was Adorama's diligence in keeping me informed while this product was on back-order. They went above and beyond in service, ensuring I knew I could get a full refund if I did not want to wait for the item to arrive in stock, and keeping me up-to-date on in succinct email notifications. I look forward to shopping at Adorama more in the future, they deserve my business.

great product and meet my expectation

I recently bought a Dell Inspiron 5485 2-in-1 AMD Ryzen 5 3500u laptop for my son. The laptop came with a single bar of RAM at 8GB. In order to bring out the full potential (dual channel memory) of the AMD CPU, I put in another 8GB (this purchase) to the empty slot in the laptop. Laptop has been running great and very satisfied with the performance.

Great Buy!!!

the price was more in my price range, and HP didnt have it in stock. it worked great for my laptop >>> hp 14-cf0006dx. I just needed to add another stick of ram, and this matched the ram that came with the laptop. make sure the speeds and form factor are compatible, and it should be fine.

Huge boost from 8Gb Ram

I was looking to upgrade my laptop's speed and this package made it! From 8 Gb to 32 Gb is a big step. Crucial does a great job by matching your PC/Laptop model with compatible parts.

The ripple effect of a camera upgrade.

I upgraded my camera (Nikon D3s to Nikon Z7) which increased the resolution by about 4 times/ All of a sudden adding photo to a Lightroom Catalog went from just be a patent to come back tomorrow. My PC had on 16 Meg of memory and a old hard drive. I bit the bullet and ordered the memory and SSD. My PC is a small footprint gaming desktop by ASUS. Adding the memory took more disassembly than expected, but it was straight forward project. The performance increase in Lightroom was incredible even before I had the SSD installed and opertional. Went from 16 Gig to 32 Gig.

10/10 would definitely recommend

Ordered this to increase the amount of RAM in my wife's new gaming laptop. Good price, arrived on time and without issue, and works perfectly! Installation was a breeze. I was a little skeptical to order at first because I had never used Adorama before, but I decided to try it out and I was not disappointed! Thank you!

Works with Costco HP laptop model 14-dq1033cl. Go from 4gb RAM to 12gb.

Works perfect with my daughters HP laptop model 14-dq1033cl(The Costco one that came with Intel i5,instead of Intel i3). It now has 12gb ram. Huge improvement. Easy to install-just watch youtube video on how to open case. For this laptop I highly recommend.

Works great in a 2019 iMac

By David D.

I've been using this in a 2019 iMac for the last couple weeks and so far so good. Easy install and the ram is recognized by the operating system. I haven't had any issues with running out of memory like when I had only 8GB (where the computer would slow down at times). I'm really pleased with the purchase and would definitely recommend it to anyone else considering an iMac to avoid Apple's extremely high ram prices.

More speed. More battery life. More memory capacity. Fuel your next-gen laptop.
In the ever-changing world of technology, any component more than five years old is usually in need of an update. At seven years old and counting, thates where DDR3 memory is at: laptops can only do so much with it. Since the introduction of DDR3 memory technology in 2007, processors have doubled in capability, SSDs have revolutionized throughput, and graphics cards have drastically increased frame rates, leaving memory as a limiting factor. With Crucial DDR4 SODIMMs, crush the DDR3 memory bottleneck and unlock a new standard of performance.

More Energy Efficient
Extend battery life by using less power. Operating at just 1.2V compared to 1.5V for standard DDR3 memory, Crucial DDR4 SODIMMs consume 20% less voltage than standard DDR3 technology. Crucial DDR4 SODIMMs also contain other efficiency features, for an overall power reduction of up to 40%.

More Density
Pack more memory into your laptop than ever before. Crucial DDR4 SODIMMs debut in densities up to 8GB, and as DDR4 technology develops, modules are projected to hit 32GB - allowing you to install twice as much memory as you could in a DDR3 system. Since laptops only have 1-2 memory slots, high-density Crucial DDR4 SODIMMs allow you to overcome this limitation and install more memory for faster mobile performance.

More Speed
Load applications faster and run demanding programs without lag. Crucial DDR4 SODIMMs debut at 2133 MT/s -more than 30% faster than DDR3 modules
