Increased speed. Increased battery life. High memory capacity. For your next-generation laptop.
In a world of constant technological change, components that are more than five years old always need to be modernised. And at the age of seven, DDR3 memory is quite old. Laptops have much greater potential. Since the introduction of DDR3 memory technology in 2007, processor capacity has doubled and SSD throughput and graphics card frame rates have increased dramatically. The only limiting factor so far has been memory. Crucial DDR4 SODIMMs also overcome this bottleneck, so that nothing stands in the way of a new standard in performance.

More energy efficiency
Increased battery life thanks to lower power consumption. Crucial DDR4 SODIMMs operate at 1.2 V, whereas standard DDR3 memory components use 1.5 V. This corresponds to a reduction of about 20%. Crucial DDR4 SODIMMs, however, have even more efficiency features that enable an overall reduction in power consumption of up to 40%. ...
