Superior DDR4 technology This quad rank 32GB PC4-17000P server memory module, with a speed of 2133MHz and a 17066MB/s data rate, is an easy way to increase the performance of your DDR3 compatible HP ProLiant server. Introduced in 2014, DDR4 is the most advanced memory format currently available on todays market. This DDR4 delivers 50% more bandwidth than its DDR predecessor, which makes your CPU and overall server more productive, and is 40% more energy efficient which reduces running costs. Performance and security With the integration of an ECC (error-correcting code), this HP server memory module shields your system from data corruption, and thus avoids system downtime that would come as a result of this damage. The ECC automatically searches for minor errors in your server, corrects any defects that it finds, and gives you piece of mind that internal issues will be solved. There is also a register (buffer) placed in this server memory module, which fixes memory modules into a stable position and ensures that the CPU has easy access to the data that it requires.
