The IBM 70XX-7058 represents a high quality and reliable memory upgrade or replacement option for IBM servers and systems that support CUoD (Capacity Upgrade on Demand) technology. This particular product comes with a total memory capacity of 8192MB, distributed across four DIMM (Dual In-line Memory Module) units, each providing 2048MB of DDR1 (Double Data Rate 1) RAM. DDR1 technology, being one of the earlier types of dynamic RAM, ensures a stable and proven performance boost for older systems in need of memory enhancements. Besides its capacity to enhance system performance through increased memory, the CUoD feature stands out by allowing users to scale their system's memory capacity based on demand, providing flexibility and cost efficiency in server management. This makes it an ideal solution for businesses looking to optimize their IT infrastructure without immediate full-scale upgrades. As a part of IBM's acclaimed line of server memory solutions, the 70XX-7058 DIMMs ensure compatibility and reliability, undergoing rigorous testing to meet high standards of performance.
