Apacer Wide Temp RDIMM (Wide Temperature RDIMM) is especially designed for harsh climate and special environmental conditions. Able to operate in temperatures ranging from -40°C to 85°C, it is applicable for industrial, military, aeronautical and vehicular systems that face extreme environment challenges. In addition to the use of original industrial-grade DRAM IC, Wide Temp RDIMMs also use industrial-grade wide-temperature-range passive parts with 30u” gold plating PCB to improve anti-oxidation and ensure stability of signal transmission. Wide Temperature RDIMMs have also passed industrial verification testing for high/low temperatures and the most stringent 48-hour thermal cycling test, ensuring their ability to operate for long hours in extreme environments.

Insists on using industrial-grade chips


The misuse of commercial IC increases the instability and risk for smart devices, decreasing product lifespan and potentially causing malfunctions. Apacer has long insisted on using industrial-grade chips from original manufacturers in its wide-temp solutions. With Industrial wide-temp IC, Apacer’s industrial memory modules can ensure the stability of operating in harsh environments, where temperatures constantly fluctuate.
