Maximise your servers potential This quad rank PC4-17000 HP server is the ideal upgrade for your HP ProLiant Gen9 server. Designed in 2014, DDR4 is the most advanced version of DDR technology, and offers the best features for your system. Voltage is low with DDR4 technology, which lowers power consumption and increases energy efficiency, thus reducing operational costs. Bandwidth is high, which means more memory can access your CPU, and therefore server tasks can be completed more efficiently. Improve your server security With the integration of an ECC (error-correcting code), this product protects your server from internal data corruption and system failures. The ECC constantly looks for internal faults in your server and corrects them, which gives you peace of mind that internal issues will be resolved. There is also a register (buffer) fitted in this server memory module, which distributes constancy to individual memory modules, and improves the reliability of your server as a whole.
