To aid the design of defence projects, Apacer has successfully developed an anti-vibration server memory for defence applications. It’s called XR-LRDIMM (Extreme Rugged Load-Reduced DIMM), and it features strengthened shock and vibration resistance and reliability.

Apacer has a complete range of rugged memory, and has released a series of anti-vibration products such as XR-LRDIMM, XR-DIMM and Rugged SODIMM. Apacer claims that its XR-LRDIMM is currently the only extremely rugged server memory module with anti-vibration and anti-shock performance on the market. In the past, server systems used in the environments of defence aircraft, naval vessels and armoured vehicles had to withstand severe shaking or strong impacts for extended periods, but choices were limited to conventional standard server memory, which was insufficient and unsuitable.

The result was that the stability and reliability of key data transmission was often in a high-risk state. Apacer’s XR-LRDIMM features a load-reduced server system, which can provide a niche industrial memory solution with shock resistance, stability and durability for servers that suffer from abnormal operation, data loss or component failure due to vibration.

Unlike the golden finger connector interface used by standard memory, Apacer’s XR-LRDIMM employs an innovative board-to-board connector, which connects to the motherboard through three highly stable 100-pin connectors.

The board socket is docked, and supplemented by two mounting holes, which can be firmly connected with the motherboard layer by layer to provide stable high-speed signal transmission quality and prevent the memory module from loosening or displacing due to vibration. For vertical applications such as defence, aerospace and in-vehicle systems that demand shock and vibration resistance, it creates unmatched value.

Adopting a load-reduced server memory (LRDIMM) design, Apacer’s XR-LRDIMM can effectively reduce bus load and improve performance, while overcoming various external shock and vibration tests in harsh environments to meet the operational requirements of long-term stability that high-end defence systems demand.

In addition, Apacer’s XR-LRDIMM supports multiple protection technologies such as Anti-Sulfuration, Underfill, and Conformal Coating, demonstrating Apacer’s extensive expertise in customisation. Apacer’s strength and innovation lead the development of the industry.
