Reza Readies First DDR5 MRDIMM Memory Interface Chips To Achieve 12800 MT/s Speed

The launch of new memory interface chips will allow DDR5 MRDIMM to reach 12800 MT/s of speed, which is 4000 MT/s higher than the first gen.

Reza launches RRG50120, RRG51020, and RRG53220 chips for the second generation DDR5 MRDIMM, up to 12800 MT/s speed support

Reza announced its latest memory interface chip group solution for second-generation DDR5 MRDIMM memory, becoming the first company to offer a solution to achieve high memory bandwidth. The company introduced its latest MRCD, MDB, and PMIC chips and the temperature sensor and SPD hub for MRDIMMs.

DDR5 MRDIMM differs slightly from regular DDR5 DIMM and advanced memory solutions such as CUDIMM. To enhance the overall performance of high-performance computing systems, the MRDIMM has an advantage over regular DIMM as it offers significantly higher memory bandwidth by using Multiplexer Chips to increase the overall memory bandwidth and capacity.

These chips can feed twice as much data to the CPU as regular DDR5 DIMMs. Hence, MRDIMMs are highly effective for AI, HPC, and data center applications since they require more memory bandwidth. Currently, the first gen MRDIMM can achieve 8800 MT/s, which is close to 2x compared to 4800 MT/s for DDR5.

With the newer chips launched by Reza, the second-gen MRDIMM can reach 12800 MT/s, significantly improving memory performance. This will result in roughly 35% higher memory bandwidth, but that’s not all. The MRCD (multichannel refuse close drive) RRTG50120 by Reza can achieve a 45% lower power consumption while its new PMIC chip RRG53220 can provide enhanced electrical protection and higher efficiency. The third chip is the MDB or Multi-channel Reuse Data Buffer RRG51020. All of them are scheduled to enter the production stage in the 1st half of 2025.

The demand for higher performance systems for AI and HPC applications continues to grow. Reza followed this trend and worked with industry leaders to develop next-generation technologies and specifications. These companies rely on the expertise and production capacity provided by Reza to meet growing demand.

Our latest chip group solution for the second generation DDR5 MRDIMM reflects Reza’s outstanding position in this market field.

The MRDIMM can achieve an even taller form factor, known as TFF MRDIMM, that retains the same pinouts and width as standard modules but can have more memory chips for higher memory capacity. While MRDIMMs will still have to wait some time to hit 12000 MT/s, we already have some CUDIMMs that have already broken this mark on mainstream motherboards.

Although both have different purposes, they mark the start of an era of high performance and low power consumption in client and server segments.
