Works great with 12th Gen Intel laptops
Bought this to upgrade the RAM in a Lenovo Legion 5 Pro with a 12th Gen Intel CPU. Works perfectly and runs at DDR5-4800 as advertised. Same latency (CL40) as the default RAM, so it shouldn't have any compatibility issues. Decent value for money considering the prices of DDR5 memory nowadays.

Memory sector failure that is hard to detect
Bought this memory more than 2 months ago, installed on my new laptop. When gaming I got freezes and disruptions in PC work. For 2 months I was troubleshooting, tried almost everything. Freezes are random, do not happen for 2 days, then 5 in a row. Windows memory test showed nothing. My final decision was to replace memory and voila 15 days of excellent laptop work AIDA tests show that there is an issue with one of memory sectors that can not be traced by common win check So bad I can not refund anymore nor use it/sell Crutial seems not to care about such things

Outstanding Performance Upgrade for DDR5 Laptops - Worth Every Penny
After upgrading my new laptop with this Crucial 64GB DDR5 kit, I can confidently say it's been a game-changer for my workflow. The installation was straightforward, and the modules were immediately recognized at the rated 4800MHz speed. The CL40 latency might seem high compared to DDR4, but that's typical for early DDR5, and the increased bandwidth more than makes up for it. I've noticed significantly improved multitasking performance, especially when running multiple virtual machines and heavy design software simultaneously. The build quality is exactly what you'd expect from Crucial - solid and reliable. The modules run cool even under heavy loads, and I haven't experienced any stability issues or BSODs since installation. Power consumption seems efficient, which is crucial for laptop battery life. For content creators and professionals who need to future-proof their system, this kit is ideal. The 64GB capacity gives you plenty of headroom for demanding applications, and the DDR5 technology ensures you're ready for upcoming software requirements. The price point might seem steep, but considering you're getting cutting-edge DDR5 technology and a massive 64GB capacity, it's actually reasonable for what you're getting. Just make sure your laptop supports DDR5 and can handle 64GB before purchasing. Pros: Excellent stability Great for multitasking Future-proof capacity Reliable brand Good thermal performance Cons: Premium price point Higher latency than DDR4 (though normal for DDR5) Overall, if you need high-capacity, modern RAM for your DDR5-compatible laptop, this Crucial kit is a solid choice that delivers on its promises. 4.5/5 stars

Works well in Dell XPS 15
Purchased this memory to upgrade my 2023 Dell XPS15 from 16GB to 64GB of memory. The back of the laptop came apart easily and installation was a breeze. The laptop does take a while to boot 1st time and does throw up a screen that indicated memory size has changed, but it's simply "OK" and it boots up. Since first boot in now boots normally and works flawlessly. If you're after a memory upgrade for your XPS 15 I'd recommend these Crucial DDR5 modules.

Funciona en Dell G15 5520 - Leer descripción
Funciona de maravilla con la Dell G15 5520. Pero, como dicen otras reseñas, hay que tener paciencia. La primera vez que instalé los dos módulos que compré (2 de 16gb), los instalé los dos al mismo tiempo y la computadora se quedó trabada antes del logo. Después seguí este procedimiento: 1. Desconectar la batería y el cable de alimentación 2. Reemplazar solamente 1 de las ram de fábrica con 1 de las nuevas RAM 3. Reconectar la batería 4. Prender la computadora, esperar a que el sistema reconozca la nueva batería (tarda unos minutos a veces, no desesperar) y darle OK al mensaje de la BIOS que dice que la configuración de RAM cambió 5. Iniciar sesión y ver en el Administrador de tareas la RAM (en la pestaña de rendimiento). Debería aparecer los 8gb + 16gb = 24gb 6. Apagar el equipo 7. Desconectar la batería y el cable de alimentación de nuevo 8. Reemplazar la RAM vieja restante 9. Reconectar la batería 10. Prender la computadora y esperar nuevamente el mensaje de BIOS 11. Iniciar sesión y confirmar en el administrador de tareas que todo está en orden. Ojo. Para la Dell G15 5520 la página de Crucial menciona que el máximo admitido por la tarjeta madre es de 64gb pero en la página oficial de Dell menciona que son 32gb. Yo me fui a la segura y le instalé 2 sticks de 16gb ya que es una de las configuraciones admitidas según la página de Dell. Excelente rendimiento de la RAM, muy recomendada y seguir las instrucciones para no tener problemas. Recuerden usar una pulsera anti ESD o bien, hacerlo con guantes de látex para evitar descargas eléctricas.
