Optimal Server Memory Upgrade Bundle This quad rank 512B PC4-1700PL server memory upgrade bundle (16x32GB), with a speed of 2133MT/s and a 17000MB/s data rate, is the optimal way to give a performance boost to your HP ProLiant Gen9 / Apollo server. DDR4 was introduced in 2014 and is the most advanced memory format currently available. It delivers 50% more bandwidth than its DDR predecessor, which enables the CPU to complete more tasks, as well as 40% more energy efficiency which reduces the costs of running your server. Enhanced Server Reliability This server memory module features an ECC (error-correcting code) which discovers and corrects the most common kinds of internal data corruption, which prevents negative impacts such as system crashes or downtime. The modules in this bundle are load reduced DIMM (LRDIMM). By using modern buffer chips, LRDIMM increases server capacity and speed for efficient server performance. This bundle is compatible with the HP DL360, HP DL380, BL460c, ML350 Gen 9. For any questions about this bundle or any other products in our range, get in touch with our experienced range.
