Good with Risk
Reliable and easy to swap/mount. Amazon, please be careful with the packaging though, it was a risky play to send this in just a polybag.

Bei tempi quando ram così te le tiravano dietro a due spiccioli
ram onesta come prestazioni e sempre affidabile. La utilizzo su mini pc integrato N150 a basso consumo che uso come micro server / NAS casalingo e non ha mai dato alcun problema. Prestazioni commisurate alla classe dell'oggetto, quando la comprai aveva un ottimo rapporto qualità prezzo, ma ora...

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.
