Crucial CT2K8G48C40S5 16GB (2x8GB) DDR5 SODIMM 4800MHz C40 1.1V Notebook Laptop Memory
Faster processing and file manipulation Crucial DDR5 Laptop Memory can empower your computer to transfer data 50% faster than DDR4 at launch, resulting in shorter load times, file transfers, downloads, lag time and improved refresh rates. Due to higher bus efficiency, DDR5 technology is not just faster than the previous generation, it’s better. Responsive multitasking on the go Crucial DDR5 offers 50% faster speeds than DDR4 at launch, empowering laptop users with extreme performance right out of the box. Even more impressive, Crucial DDR5 Laptop Memory is optimized for enhanced performance and multitasking, not just during testing, but in real-world conditions. Opening more browser tabs and switching between apps now feels more responsive than ever. Improved productivity with innovative channel architecture Significant improvements to DDR5 channel architecture can help you get more work done in less time. With nearly 2x the bandwidth of DDR4, enabled by faster speeds, longer burst lengths, twice the banks and bank groups, two 32-bit channels, and improved refresh schemes, Crucial DDR5 still outperforms DDR4 with higher latency numbers. Optimized power efficiency For improved efficiency and stability, Crucial DDR5 introduces on-module voltage regulation with a power management integrated circuit (PMIC), which was on the motherboard with older memory technologies. This results in improved signaling and cleaner power regulation for the modules (SODIMMs). Moreover, DDR5’s on-module operating voltage is only 1.1V compared to DDR4’s 1.2V. Micron quality – tested reliability you can trust As the vertically integrated consumer brand of Micron, Crucial is trusted by millions for reliability, performance, and compatibility. Unlike module assemblers, our unique relationship with Micron involves a deeper level of engineering collaboration to squeeze every ounce of performance from our products without compromising reliability.

Added 32GB DIMM (CT32G48C40S5) and Dell Vostro 7620 would not pass POST.After DIMM removed, laptop boots fine. Ordered 16GB version of the DIMM, same problem.Returning both DIMMs.

I've bought two modules of the CT16G48C40S5 Crucial memory but they didn't work inside my Dell Gaming G15 5520, despite mentioning being compatible.

It worked like a charm on my HP Elitebook 845 G9. Initially i was skeptical if it will work on my latest Elitebook or not. It's fast DDR5 RAM.For all negative reviews, their motherboard may have some issue
Works! I already know what my laptop takes so I know what to get. However the to asus I can do a higher frequency but I know My laptop can't handle that. I got the 4800 ddr5. Glad it has the irx8 so it's faster and keeping the cas low is more beneficial. I purchased for 2 laptops
I have read the producer's comment about waiting 2-10 minutes, and I confirm that if the RAM would be compatible - this would happen.Unfortunately, with this RAM, Dell Precision 5570 doesn't do that, and I have waited plenty, tried different RAM combinations, different ports - nothing works.This RAM is not compatible :-(
Compatibility was confirmed on site but this RAM did not work and stopped the computer from booting up. Inserted fine and but I tried this on two different computers but neither one of the purchased memory cards worked
I added 16GB to a brand new Dell Vostro 7620. Very easy install, you do need to be patient the first boot after installing the RAM, it needs to do check the RAM.Just ordered another Vostro 7620 for another user, just ordered another CT16G48C40S5!If you think the install failed, just be patient, the k/b lights up but nothing for a few minutes, then it boots just fine!
Worked perfectly in Vostro 7620. Had to wait about 2 minutes on first boot after install (keyboard lights on, screen blank) before it passed POST and continued to boot.
i did not know that installing in one system the ram is accepted straight away while another system requires memory checking first start-up. it took half a day to figure that out but there were no error detected in the ram stick as I thought initially
