  • Lower 1.10 V operating voltage improves system efficiency
  • On-module power management optimises energy use
  • Intel XMP 3.0 profile enables simple BIOS tuning

16 GB DDR5 4800 UDIMM

This 16 GB DDR5 module runs at 4800 MT/s with a CL40 latency and 1.10 V operation. It is built for desktop systems that support DDR5 memory and Intel XMP 3.0 profiles. The unbuffered, non-ECC design suits mainstream gaming and productivity workloads.

Before ordering

Verify that your motherboard and CPU officially support DDR5 memory and 288-pin UDIMM slots. Check the qualified vendor list for 4800 MT/s operation at CL40 timing and 1.10 V. Ensure the BIOS is updated to enable Intel XMP 3.0 so the module can run at its rated speed.

Upgrade path

The module delivers 1.5x the speed and nearly 2x the bandwidth of DDR4, making the jump worthwhile when moving to a next-generation multi-core platform. It replaces standard DDR4 UDIMMs where the board and processor require DDR5. The on-module power management improves efficiency for sustained heavy workloads.
