I have a Mac mini 2018 with i7 and 8 GB of RAM with a 5700 XT as the eGPU setup. I play lots of video games and using this previous setup to run at max graphics at 4k is impossible for most games. Many games crashed because of insufficient memory issue, so I decided to upgrade the RAM to 16 GB betting this could improve the situation, and honestly I didn’t have high expectation. To my surprise, it paid off! I can now reliably play Monster Hunter World: Iceborne at max graphical settings in 4k with high resolution texture. Resident Evil 2 and 3 Remakes also work at almost max graphical settings in 4k flawlessly. If you are like me and want to play modern video games at pretty much the highest settings with the Mac mini with eGPU setups, I highly recommend this 16 GB RAM kit.

The ram was easy to order and easy to install. My computer immediately recognized the ram as has run well ever since installation. I would recommend Crucial and B&H Photo for all your computer needs.

Crucial IS Micron, so this is a minor technicality, but I ordered a Crucial SODIMM (CRCT16G4SFD8) module and was substituted a Micron-branded one (MTA16ATF2G64HZ-2G6J1) instead. I really don’t mind, but there was no warning for the substitution. In hindsight I should have ordered a PC4-19200 module but so far so good! And the price has skyrocketed so much that going to find the perfect module can wait.

Always plug and play with Crucial Memory. Have always had good results with Crucial. This purchase was no exception. Replaced the single 8 gig chip provided in my Dell Vostro 7590 laptop with this set and everything booted up great and memory has been operating smoothly.

So I purchased this RAM for my iMac 2019 27in 5k because the base RAM is laughable for such an expensive machine. That being said it was a breeze adding the additional 16gbs of RAM to my iMac and it works great, the Mac runs even better than it already did. Highly recommended for an upgradable PC or Mac.

I actually bought higher end performance ram by crucial but my new Dell laptop did not support ram with an XMP profile; this ram works flawlessly.

My older Dell laptop (inspiron 15-7569) came with only 8gb ram; upgrading to 16gb was the best option other than buying a new laptop. So for under $70 I get a performance boost and don’t have to shell out $1000 for a new laptop. And I did it myself using instructions found on the Crucial website.

My purchase was delivered to my door within a couple of days. The service from B&H Photo Video was great. The RAM worked perfectly and was exactly what I needed to speed up my laptop. Highly recommended! I actually purchased my laptop here a couple of years ago as well. I am an IT Consultant so I make my living working with stuff like this and I’ve found B&H to be a great place to go for both value and service.
