Crucial 8GB DDR5 4800MHz UDIMM RAM comes with PC5-38400 of transfer speed. This UDIMM Unbuffered memory has a CAS latency of 40. This memory module allows for short-term data access. It improves loading applications, browsing the Web, or editing a spreadsheet so the speed and amount of memory in your system play a critical role. It has an operating voltage of 1.1V. The speed and amount of memory in your system play a critical role. Faster Load Times and File Transfers Crucial 8GB DDR5 4800MHz UDIMM RAM allows your computer to transmit 50% more data than DDR4 at startup, resulting in faster load times, file transfers, downloads, refresh rates, and less lag time5. DDR5 technology is not only faster than previous generations, but it is also superior. More Responsive Multitasking Crucial DDR5 UDIMM RAM offers 50% faster rates than DDR4 at launch, providing users with extraordinary performance right out of the box. Even more surprising, Crucial DDR5 is tailored for improved performance and multitasking in real-world settings, not only during testing. Opening more browser tabs and navigating between apps now feels more fluid than ever. Extreme Innovation for Stable Performance Crucial DDR5 RAM is a technical leap forward from the previous generation, featuring two separate 32-bit channels per module for optimized performance. Crucial DDR5 is built to maintain the same dependability as the previous generation, even with the hard demands of next-generation computing, thanks to on-die ECC (ODECC) at the component level. Optimized Power Efficiency Crucial DDR5 Memory introduces on-module voltage regulation with a power management integrated circuit (PMIC), which was previously found on the motherboard with prior memory technologies, for greater efficiency and stability. This leads to better signaling and cleaner power for the modules (DIMMs). Furthermore, DDR5's on-module operating voltage is merely 1.1V, compared to 1.2V for DDR4.
