Many other memory module companies use a generic module for a variety of systems, and may encourage you to purchase a cheaper module for your system. Kingston takes design to a higher level and manufactures system specific memory.

This means the design is customized to meet the strict memory specifications that ASUS/ASmobile insist upon. The design is fine-tuned to match the timing of the RS Series Server RS163-E4/RX4 model, to reduce noise and heat, and allow for the most efficient communication between the memory and the CPU. Kingston also tests the module in the system using popular applications, operating systems and the original equipment manufacturer's diagnostic program.
