DDR5 MRDIMM chipset boosts server bandwidth
Renesas announced its third-generation DDR5 Multiplexed Rank DIMM (MRDIMM) chipset, delivering server-class speeds of up to 16,000 MT/s. The memory interface components, including the RRG5013 multiplexed registering clock driver and the RRG5103 multiplexed data buffer, are designed to meet the high memory bandwidth requirements of AI data centers, cloud infrastructure, and accelerated computing workloads.
Renesas says the Gen 3 MRDIMM chipset achieves 25% higher bandwidth than its second-generation devices while preserving standard DIMM form factors and system compatibility within existing DDR5 infrastructure. Gen 3 also introduces Device Equalization Self-Train Mode (DESTM) Quality Indication Status to improve system visibility and robustness. This feature enables users to fine-tune timing and receiver equalization training to maximize signal margins.
Renesas is working with leading CPU and platform partners to enable MRDIMM Gen 3 adoption in future server platforms. The RRG5013 and RRG5103 are sampling to select customers, including all major DRAM suppliers. Production availability is expected in the second half of 2027.
