Exceed Server Potential This HP 4GB, PC3-12800R server memory kit works with a speed of 1600MHz and a bandwidth rate of 12800MB/s thereby ensuring that operations can be executed and sustained at high speeds. HP is one of the elite technology manufacturers, with over 70 years- worth of experience in delivering the highest quality products all over the world, building a reputation of trustworthiness.

DDR3: The Elite Memory Upgrade DDR3 has received a plethora of updates over DDR2 memory technology. Advanced power usage and cooling properties, combined with double the speed means that DDR3 represents the elite memory technology for getting the most out of your server’s capabilities. A rise in prefetch length from 4 to 8 bits is a 50% increase on DDR2, ensuring that data moves across the data bus without a problem. The increased power consumption efficiency stems from the reduction in voltage levels from 1.8v-1.9v to 1.5v, meaning that, on top of the performance upgrades, DDR3 is more cost effective in the long- run.

Enhance Security Enhance your server’s security with ECC (error- correcting code). Never has it been more integral to keep your data safe, in a world where maximised system uptime can provide a significant competitive advantage, ECC automates this, ensuring that the most common types of interior data corruptions are instantaneously located and eradicated. Furthermore, this server memory kit is registered (buffered), the register can be found between the DRAM modules where it generates stability throughout the individual modules, this stability then passes through and engulfs the overall system.
