Great performance and reliability Maximise your systems potential with this Cisco 815100-B21 server memory module. With a speed of 2666MHz, this PC4-21300 32GB dual rank server allows your HPE ProLiant Gen9 or Gen10 server to achieve the highest level of efficiency. Maximise efficiency This DDR4 PC2-4200R single rank server memory module provides a great opportunity to boost your server. DDR4 technology guarantees the best performance by preventing costly DIMM replacements. DDR4 is the most up to date version of DDR, and its low voltage will improve energy performance for your company. Bandwidth is also increased by 50% compared to DDR3, which means that more data will reach the CPU but without incurring in any bottlenecking within your system.
