The LENOVO 46C0513 kit comprises two 4GB DDR2 memory modules, totaling 8GB, designed for server systems requiring high-density and compact memory solutions. These Very Low Profile (VLP) modules are particularly suited for blade and dense rack server configurations where space is at a premium. The ECC (Error-Correcting Code) feature enhances data integrity, making these modules ideal for critical systems where downtime can have significant consequences. Operating at a speed of 667MHz (PC2-5300), they provide a balanced performance for legacy systems, ensuring that older servers can continue to deliver reliable service in demanding environments. The CL5 latency means that these modules can handle tasks with reasonable speed and efficiency, vital for maintaining system responsiveness under load. They are designed to offer a practical memory upgrade solution, extending the useful life of existing server infrastructure, thereby providing organizations with a cost-effective alternative to complete system replacement.
