Met expectations. Buy with confidence.
Purchased to upgrade an older (5 years) Laptop that has an upper RAM limit of 16gb, came with 8. Recognized immediately. Ran a few memtest's including Memtest86+, everything was good, no errors. Matched expected capacity, speed etc. Well oackaged, standard plastic holders. No problems, buy with confidence.

Perfect!
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.

If your computer sess has one ram slot but to modify it actually has two. Totally worth it!
They work exactly what I want them to do. Make my slow pc faster! Totally worth it!

Las memorias Crucial tienen muy buena calidad, pero en mi caso no funcionaron correctamente con mi Acer Predator porque la velocidad que soporta mi PC es menor a la de estas memorias, así que fue más una mala decisión de mi parte. El sistema se colgaba durante el trabajo, pero el proceso de devolución fue muy eficiente. Este año ya conseguí unas que sí fueron 100% compatibles y funcionan perfecto.

Great quality and desperately needed memory upgrade.
Wow, what a difference. My Dell XPS 15 was getting really sluggish. It had 16GB of ram but I was sitting at 85% or higher of memory usage. Did some research and found that the max memory I can have is 64GB so I bought this kit and my PC is WAY more snappy and responsive. Now even when I start pushing the limits with Msft Teams, Outlook, several webpages, Powerpoint and more running, it gets up to about 30% memory usage. I have not tried editing videos yet but I suspect that will work smoothly given it's snappy with all the other memory hogging applications that I've run simultaneously. I've worked in the tech space for years (including at a major CPU company) and know Crucial is a great quality memory supplier. While researching kits, I saw a LOT of no name brand solutions but knowing how important memory is in the stable operation of a PC, I didn't want to trust my system to low grade memory chips. Overall, very happy with this memory kit...it's made a big difference in performance on my laptop.

Exactly as expected
Bought as an upgrade for my laptop MSI GL75 9SDK Started working right after installation without any tuning. CPU-Z shows full match to the described characteristics. Dual-channel mode just works. The system looks to be pretty stable and fast. Wrt performance it's probably better to buy a smaller volume bars which may come with smaller timings, but 19 is already pretty good IMO. I any case I've bought this pack to have enough volume but not enough speed, and I've got exactly what was expecting. Maybe except the price which taking account the shipment and import clearance taxes turned out to be higher than from local retailers (overall local Belarus prices are 14% cheaper for the same memory) If anyone curious there is dmidecode below: Array Handle: 0x003A Error Information Handle: Not Provided Total Width: 64 bits Data Width: 64 bits Size: 32 GB Form Factor: SODIMM Set: None Locator: ChannelB-DIMM0 Bank Locator: BANK 2 Type: DDR4 Type Detail: Synchronous Speed: 2667 MT/s Manufacturer: Micron Serial Number: 2F3A12AE Asset Tag: 9876543210 Part Number: 16ATF4G64HZ-2G6B4 Rank: 2 Configured Memory Speed: 2667 MT/s Minimum Voltage: 1.2 V Maximum Voltage: 1.2 V Configured Voltage: 1.2 V Memory Technology: DRAM Memory Operating Mode Capability: Volatile memory Firmware Version: Not Specified Module Manufacturer ID: Bank 1, Hex 0x2C Module Product ID: Unknown Memory Subsystem Controller Manufacturer ID: Unknown Memory Subsystem Controller Product ID: Unknown Non-Volatile Size: None Volatile Size: 32767 MB Cache Size: None Logical Size: None

Habe den RAM als Erweiterung für mein Synology DS224+ gekauft – wurde sofort erkannt und läuft absolut stabil. Der Einbau war unkompliziert und in wenigen Minuten erledigt. Seit dem Upgrade läuft das NAS spürbar flüssiger, gerade bei mehreren gleichzeitig laufenden Diensten. Gute Qualität, fairer Preis und zuverlässige Leistung – genau das, was man sich von Crucial erwartet. Klare Kaufempfehlung für alle, die ihr NAS aufrüsten möchten!
