The LENOVO 00D4985 is an 8GB DDR3 Very Low Profile (VLP) Registered DIMM (RDIMM) designed for server environments where space and cooling are critical factors. This module operates at a reduced voltage of 1.35V, aligning with the PC3L designation for low-voltage memory, which contributes to lower power consumption and heat generation within the server chassis. With a capacity of 8GB, it significantly enhances system memory, supporting more simultaneous applications and improving the overall efficiency of memory-dependent server tasks. The module's 1333MHz speed, combined with a CL9 latency, balances quick access times with reliable performance, crucial for maintaining server responsiveness under load. The ECC (Error Correction Code) feature is a key attribute, reducing the risk of data corruption and system failures by automatically detecting and correcting internal data errors. Its 1Rx4 configuration (single rank, four banks) and VLP form factor make it especially suited for dense server configurations where space is at a premium and airflow is limited, allowing for improved system scalability and thermal management in tightly packed server environments.
