XR-LRDIMM: The world's firstanti-vibration and anti-shock server memory module

Apacer’s XR-LRDIMM(Extreme Rugged Load-Reduced DIMM) is currently the only extremely rugged server memory module with anti-vibration and anti-shock performance on the market. 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 defense, aerospace and in-vehicle systems that demand shock and vibration resistance, it creates unmatched value.
