Solid RAM upgrade with good value and speed
Why I ordered this item: My laptop is stuck with an old 16GB kit and Chrome eats it alive with like 30 tabs open. I wanted more headroom for VMs and general multitasking. Likes: * Installed easy, computer booted right up and saw the full 32GB in the BIOS. * Speeds are zippy. I ran a few benchmark tests after install and my scores jumped up a good amount. * It runs XMP fine on my board, didn't have to mess with timings or anything. * No heat spreader on these, just bare green PCBs. Kind of a plain look but they fit in my laptop's memory slots perfectly. * Price for 32GB of DDR5 is pretty great right now. No likes: * The label on the stick is tiny and hard to read if you ever need to double check part numbers. * The timings aren't the snappiest out there. If your motherboard supports faster kits you might notice a difference in really demanding stuff. Would I pay full price for this product: Yes Final thoughts: This is a simple memory upgrade that got my system feeling less jacked up under heavy loads. Chrome with 30 tabs and a VM running in the background doesn't choke my machine anymore.

Fantastic Ram, ddr5, thats incredibly hard to find and works fantastic in an Asus 2022 M16
DDR5 So-Dimm. 32gb. From crucial and it uses micron chips and is absolutely bulletproof when it comes to ram. Passed all ram tests that were ran twice. Took all of 10 minutes to install this ram into a brand new Asus 2022 M16 gaming laptop that was only running 16gb so it needed it. Its crazy fast, dual channel stock, and works perfectly as expected. Of course ram is spendy nowadays but that is to be expected as every component is either short on stock, hampered by logistical nightmares of shipping/sourcing/etc, or just scalpers seeing a hole to exploit so they can turn a quick buck by buying up all the stock then raising the prices 25-50% and selling it to everyone that needs it because guess what? Stocks out, and their stock is in, and if you need the item youre forced to pay that amount or suffer which is ridiculous. Anyways, get this ram before it sells out and youre forced to pay 1.5X or more than msrp ( and the price alone has jumped 20% since i bought it a week or two ago which is nuts already ) TL;DR - Fantastic Ram, Great for those new kick butt Gaming laptops like the Asus 2022 M16 i just got that runs the alder lake chipset that runs ddr5 and makes use of the ram. Get it now before its gone

Great Early Lead!
*** Overall Thoughts *** (Jul 2022) One of the best DDR5 ram sticks for laptops out right now. A great value price from a very respectable company. If you need an upgrade, this is probably your best shot right now. *** General Warnings *** - CL40. Most "good" DDR4 sticks are around CL18 or CL20, or the "clock timing." It is on the slower side, but the DDR5 technology, and pretty high clock speeds def will make up for it. - RAM limits. Most modern laptops at the moment (unless you're buying a thousands of dollars one), have limits to the amount of RAM that can be upgraded, so be sure to check on that to ensure the capacity you are purchasing does not exceed the maximum supported by your laptop. - Packaging. The ram stick comes in a plastic box that keeps it isolated, but still very vulnerable to damage, be very cautious when handling as to not step, drop, or put too much pressure on it in any way. *** Conclusion *** Having it on my system feels extremely nice, whether you buy the 16gb or 32gb model, make sure to choose the one that is best for your system. As DDR5 is still rather new, especially for laptops, the choices will widen up for the RAM sticks available, but for now, these are the best for their price and punch!

Exceptional Performance Boost with Crucial DDR5-4800 32GB RAM Upgrade
Upgraded my laptop with an additional Crucial DDR5-4800 32GB module, bringing the total to 64GB. Before the upgrade, with just one 32GB stick, AIDA64 benchmarks showed 38,000 MB/s read/write/copy speeds. After installing the second module, these speeds soared to 69,984 MB/s read, 69,125 MB/s write, and 69,592 MB/s copy, with latency improving to 87.3 ns. This upgrade dramatically enhanced multitasking, productivity, and overall system responsiveness. The installation was straightforward, and the results speak for themselves. If you’re considering maximizing your system’s potential, this memory upgrade is a no-brainer. Highly recommended!

Excelente memoria RAM para edición de video profesional
Compré esta memoria RAM Crucial DDR5 de 32 GB en 2025 y la he utilizado durante aproximadamente 1 año y medio en mi portátil de trabajo, dedicada principalmente a edición de video profesional. Durante todo este tiempo ha tenido un desempeño excelente y completamente estable. Mi trabajo consiste en editar proyectos audiovisuales, incluyendo material en alta resolución y flujos de trabajo exigentes, por lo que la memoria RAM es un componente fundamental. Desde que instalé este módulo he notado una mejora en la capacidad de multitarea y en la fluidez general del sistema al trabajar con programas de edición. La memoria ha funcionado sin problemas de compatibilidad, errores o inestabilidad. He realizado jornadas largas de edición, exportaciones de proyectos y trabajo simultáneo con múltiples aplicaciones, y siempre ha respondido de manera confiable. Los 32 GB de capacidad permiten manejar proyectos complejos con mayor comodidad, especialmente cuando se trabaja con video, gráficos, fotografía o software creativo que consume una gran cantidad de recursos. Después de aproximadamente un año y medio de uso continuo, sigue funcionando perfectamente. Para quienes buscan ampliar la memoria de su portátil para edición de video, creación de contenido o trabajo profesional, considero que es una excelente opción y una compra totalmente recomendable.

You can't go wrong with Crucial
One of the few DDR5 SODIMM manufacturers it's also one of the best RAM manufacturers. RAM works like a charm. ALIENWARE USERS: Your system may not start after RAM upgrade, more alarmingly, your system may not start even if you rollback the upgrade, this is normal, just follow these steps: - Unplug power source - Unplug battery - Remove the old RAM - Place the new RAM - Press your power button for 10 seconds (with both battery and power source unplugged) - Plug your battery - Plug your power source - Turn on your Alienware system - Your system would appear stuck on rainbow keyboard, this is normal. - Just wait 5-10 minutes, your system will turn off and restart - Your BIOS will reset, you'll need to reconfigure your preferences on lid switch, mux switch, power management, battery saver, etc. - Readjust your settings and restart your system. - You'll now see your ram in your system, so you can now open 3 chrome tabs.

Works with Asus TUF A15 (2022)
Works fine for weeks now. I bought 2 so I'm running 64GB on my laptop. I'm always decompressing large files so this reduced the stress on my nvme since I have only set my pagefile to 1GB

Excelente memoria RAM.
Me arriesgue comprando la de 32 gb a pesar de que según las especificaciones de mi laptop (Dell G15 5525) solo admiten como máximo 32 gb en configuración 2 x 16 gb, lo probé y funciona de maravilla, es la mejor compra que he hecho, solo hay que tener cuidado al momento de desarmar tu laptop, yo en el proceso la dañe, procura que lo haga alguien experto, por cualquier otra cosa es excelente, lo volvería a comprar. 😻
