ADATA utilizes leading technology and strict control of each step of memory module production process to bring you unbeatable value in the Premier ProSeries DDR3-1600 (CL11). In densities of 2GB/4GB, these modules are positioned to provide users with highest-quality memory at a competitive price. Installing more memory to enhance the performance of your computer is still one of the most cost-effective approaches. With adequate memory, operating systems and applications will be able to show higher performance, allowing you to simultaneously perform more work. In business or at leisure, the Premier Pro series gives full play to your system's potential. Each ADATA Premier ProSeries memory module is subjected to 100% burn-in test, thus excluding premature failure of DRAM and guaranteeing that each memory module is factory quality. Each Premier ProSeries memory module undergoes rigorous electrical interference and noise testing to eliminate problems caused by electrical interference. With our extensive cell disturbance pattern testing, our tests include scan, march, gallop, jump, and butterfly. In one 4-GB memory module, every one of the 34,359,738,368 cells must be validated by the defect screening test to guarantee its functionality, reliability and compatibility within any operating environment.
