Supports two independent subchannels per RDIMM
Supports two physical ranks per subchannel, four physical ranks total
Supports up to 16 logical ranks (per physical rank) for high capacity RDIMMs
Provides up to 4 clocks per subchannel: 1 clock per five devices
Low Power 1.1V VDD
5 MHz (max.) I3C bus interface

With over thirty years of experience in the field, Rambus’s expertise shines through in the development of the DDR5 RCD. Their knowledge in areas like signal and power integrity is vital for the performance and reliability of these memory interface chips, which are increasingly important for AI-driven server performance.

The move to a 7200 MT/s data rate and the resulting 50% increase in bandwidth is not just a technical upgrade; it paves the way for new computing possibilities. Servers that are equipped with this improved bandwidth can handle data more quickly and efficiently, which is a significant step forward for server technology.

Rambus’s Gen 4 DDR5 RCD is a direct answer to the changing needs of advanced data center workloads. As applications like generative AI push the boundaries of current technology, this RCD is well-equipped to tackle these new challenges.

The introduction of Rambus’s Gen 4 DDR5 RCD marks a key moment for server technology. With its superior data rates, increased memory bandwidth, and preparation for future server platforms, the RCD is essential for the performance and efficiency of the next generation of AI-driven servers. Rambus’s continuous innovation and deep expertise in memory interface technology place them as industry leaders, ready to address the challenges of an ever-evolving technological world.
