Crucial Laptop Memory

The fast, easy way to improve your laptop’s performance

There’s an easy cure for a slow computer: more memory. Designed to help your system run faster and smoother, Crucial Laptop Memory is one of the easiest and most affordable ways to improve your system’s performance. Load programs faster. Increase responsiveness. Run data-intensive applications with ease, and increase your laptop’s multitasking capabilities.

Make everything on your computer faster

Memory is a component in your computer that enables short-term data access, which your computer relies on for moment-to-moment operations, such as loading apps, browsing the web, or editing a spreadsheet. Installing more memory in a slow PC is the easiest way to improve system performance quickly.

Multitask with ease

If you’re like us, you use your computer to do lots of things at once. You might be editing a document while also looking at pictures and browsing the internet. This naturally leads to a performance problem: every app you’re running requires memory and competes for a limited pool of resources. Overcome this by installing high-density modules in each memory slot on your laptop for seamless multitasking.

Install with ease – no computer skills required

With just a screwdriver, your owner’s manual, and a few minutes of time, you can install memory – no computer skills necessary. Just watch one of our three-minute install videos, and we’ll walk you step-by-step through the process. Don’t pay a computer shop to do something you can do in minutes!

Maximize the value of your system

Micron Quality

Maximize the value of your system

At a fraction of the cost of a new system, a memory upgrade is one of the most affordable ways to increase performance. Get more out of your laptop by giving it the resources it needs to perform.

Micron quality – a higher level of reliability

As a brand of Micron, one of the largest memory manufacturers in the world, Crucial Laptop Memory is the standard for reliable performance. From the original SDRAM technology all the way to DDR4, we’ve engineered the memory technologies that have powered the world’s computers for 40 years and counting. Don’t settle for anything less.

Exactly as expected
Bought as an upgrade for my laptop MSI GL75 9SDKStarted 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

4.0 out of 5 stars RAM: 1 stick was BAD, 1 stick was GOOD
Reviewed in the United States on July 4, 2021
UPDATE: Replacement RAM arrived. Installed and worked exactly as expected. Original review is below.

Purchased 2 each 16BG sticks to replace original 2 each 8GB sticks, for Alienware M17 laptop. Same timings, same speed. The only difference was the total amount of RAM. Unfortunately one NEW stick was bad. STEPS to troubleshoot problem:
1. Removed two original sticks, install new sticks, RESULT: No post.
2. Reset new sticks, RESULT: No post.
3. Install one new stick. RESULT: Posted normally.
4. Remove new working stick, replaced with other new stick, RESULT: No post.
5. Reinstall new working stick, RESULT: Posted normally.
6. Use 5x magnifying glass to look for any visual damage on bad new stick, RESULT: No damage.
7. Reinstall old sticks, RESULT: posted normally.
8. Repeat STEPS 1 through 6 again with same results. NOTE: same bad new stick observed.
Time to return new RAM sticks for replacement.
I have purchased same brand several times before without any issues. It looks like I finally got a bad stick.
I have 38 years of pc experience.

Comprei um memória de 16GB para expandir a memória total do meu laptop pra 24GB. Fiz uma pesquisa extensa antes para saber quais as melhores marcas de memória RAM, e a Crucial foi uma das principais recomendações. Tem três semanas que meu laptop está rodando com a memória nova, e consigo usar máquina virtual, rodar programas da Adobe e jogar jogos tranquilamente. Super recomendo!

A instalação no slot foi bem simples de fazer, porém encontrei um problema com o Windows, que se recusava a incializar após eu inserir a memória nova. Fui descobrir que era uma reclamação de paridade do próprio Windows mesmo, pois os slots de RAM do meu laptop estavam com 16 x 8, e o recomendado é sempre ser duas memórias de capacidades iguals, 8x8, 16x16, etc. Após configurar o Windows para aceitar a configuração 16x8, ele inicializou normalmente, e desde então, não tive mais problemas.
