Small yet powerful, Transcend DDR3L ECC-DIMM VLP modules are a mere 0.74 inches high and operating at a nominal voltage of just 1.35V. Built using the highest quality brand-name DRAM chips available, these modules not only produce less heat, but also reduce electrical load on the memory controller to offer power savings of up to 15% versus standard 1.5V. Rigorously tested to ensure superior performance and reliability, these modules are an economical solution to help significantly improve airflow and memory heat dissipation. Precise clock management for accurate synchronization across many modules On DIMM Thermal Sensor Support ECC error detection and correction Serial presence detect with EEPROM On-die termination with ODT pin Bi-directional differential data-strobe Internal calibration through ZQ pin 8 bit pre-fetch Burst Length: 4, 8 JEDEC standard 1.35V (1.28V~1.45V) & 1.5V (1.425V~1.575V) power supply
