The LENOVO 46C7504 memory module is an 8GB, quad-rank x8, PC3-8500R VLP (Very Low Profile) RDIMM designed for use in Lenovo's high-performance servers. The PC3-8500R specification means this memory operates at 1066MHz, offering fast data transfer speeds essential for server applications that demand high bandwidth. The quad-rank x8 architecture enhances data reliability and signal integrity, crucial for servers operating in data-intensive applications such as databases, analytics, or virtualization environments. The very low profile design of this RDIMM makes it ideal for use in space-constrained server environments, allowing for improved airflow and cooling efficiency within the system. This 8GB module, operating at a standard voltage, provides a substantial upgrade in memory capacity, allowing businesses to increase their server's workload capabilities and improve overall system performance without compromising on space or power efficiency.
