Crucial RAM 8GB DDR5 4800MT/s CL40 Desktop Memory

CT8G48C40U5 is the Crucial 8GB DDR5 desktop module that operates at the speed of 4800MT/s and has a CAS Latency of 40. It is an UDIMM and conforms to the industry standard DDR5 UDIMM layout of 288 pins. It is compatible with systems that can take DDR5-4800 UDIMM memory.

Empower your next-generation, multi-core CPU

Crucial DDR5 Memory has the blazing speed and massive bandwidth needed for the next generation of multi-core CPUs¹. Multitask better, load, analyze, edit, and render faster, game with higher frame rates and significantly reduce system lag for heavy workloads over the previous generation². With Crucial DDR5 Memory, harness performance that was once only possible with extreme performance memory³.

Extreme performance right out-of-the-box

Crucial DDR5 Memory can transfer data up to 1.75x faster and deliver up to 2x more bandwidth than DDR4, resulting in shorter load times, file transfers, downloads, lag time and improved refresh rates. Performance is enhanced not just during testing, but in real-world conditions².

Best value with support for both Intel XMP 3.0 and AMD EXPO

Even with CPUs that suppress memory speed, Crucial DDR5 desktop memory can reach its rated speeds with Intel XMP 3.0 or AMD EXPO turned on in the UEFI/BIOS settings⁴. Get the full value of your investment without overpaying for performance and enjoy the flexibility of using your Crucial DDR5 Desktop Memory in either an Intel or AMD build⁵.

No latency downsides with DDR5

Crucial DDR5’s system latency, measured in nanoseconds, is only up to 3% longer than DDR4 during testing⁶, meaning real-world latency performances are virtually the same. With Crucial DDR5 delivering up to 2x more bandwidth, DDR4 is still outperformed.

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 technologies⁷. This results in improved signaling and cleaner power for the modules (DIMMs). Moreover, DDR5’s on-module operating voltage is only 1.1V compared to DDR4’s 1.2V.
