Size: 32GB Style: 5600MHz
Installed without any issues in my Ugreen DXP2800 NAS. Allowed me to upgrade from 8gb. Matched the speed that was supported at 4800mhz and has been running stable for about 4 months now.

    • Perfect for UGREEN NAS
Size: 16GB Style: 5600MHz
Got it to replace/upgrade my Ugreen NAS stock ram. Easy to replace it - just watch a video on youtube or follow instructions carefully provided with the NAS. Great quality memory stick. Works flawlessly and it's super fast.

    • Does the job
Size: 16GB Style: 5600MHz
There isn't much to be said about RAM sticks; they either work or they don't. This one passed all memory tests in its new home (a white-box NAS motherboard) and is working well. Good price, too. Five stars.

    • 128GB Ram works perfectly with Alienware M18 R2 laptop, even though the max spec is 64GB RAM
Size: 64GB Style: 5600MHz
Installed two Crucial 64GB DDR5 RAM 5600MHz (128GB total) in an Alienware M18 R2 laptop. The maximum support for the laptop is 64GB total. I've read online that people have tried 96GB (2x48GB) with no issues, so I figure I try 2x64GB. It worked right away after the computer loaded with no issue. I did have a situation where the computer was randomly resetting itself and searched online for the solution - it usually means the RAM is not seated 100% properly, so I uninstalled and reinstalled and have had no issues since. Memory speed slows down the larger the GB you add. I purchased 5600 MHz speed and after installation and booting up, it's showing up at 5200 MHz which in my applications won't see any material differences - so going from 32 GB to 128 GB is a huge difference overall. Very happy with this purchase and makes my computer noticeably faster. If you use Google Chrome, you can now have all the windows/tabs you want open! I purchased them individually as it was cheaper and faster shipping than the 128GB kit (so two 64GB). ... show more
