New DDR5 RDIMM industrial DRAM for servers

Apacer has announced the launch of DDR5 RDIMM industrial DRAM modules for servers. This product fully supports next-generation data centre and server applications. It is expected to be launched simultaneously with the Intel Eagle Stream server platform in the second quarter of 2022.

The DDR5 RDIMM module was a particularly complex product to develop. It includes four new components: a DDR5 registering clock driver, a power management IC, temperature sensors and an SPD hub. It also provides a new channel architecture, based around two sets of independent 40-bit sub-channels, which enhance efficiency and reliability.

The DDR5 RDIMM modules will improve the performance, capacity, power consumption and reliability that applications seek. For example, it is equipped with a 12V power management IC to control the power load of the system more efficiently. This assists in improving signal integrity and reducing noise in circuits. It also uses two high-precision temperature sensors which accurately track all changes in temperature, diminishing the risk of overheating and increasing performance. And it is protected by on-die ECC and sideband ECC, giving end-to-end protection for data transmission and meeting the RAS demands for data centres that operate 24/7.

The modules were produced for use with Intel’s Sapphire Rapids and AMD’s Zen4 Genoa processors. They support a frequency of 4800MHz and will initially be offered in capacities of 16GB and 32GB. They are also provided with the company's patented anti-sulfuration technology.
