Speed and reliability with HP

This HP 4GB PC3-12800R server memory kit has a speed of 1600MHz and a bandwidth rate of 12800MB/s, making it a great choice to improve your system’s performance. HP is a successful and popular organisation with over 70 years of experience in computing, making HP a first choice for buying manufactured server memory.

Amplify Reliability via DDR3 Technology

The amplification in prefetch length from 4 to 8 bits, means that the speed at which informational transactions are processed across the data bus is doubled. This is combined with a breakthrough in power saving abilities, a reduced voltage rate from 1.8v-1.9v-1.5v brings low operational costs.

Reinforce Your Data’s Defence

Fortify your defences with ECC (error- correcting code), which protects your system against the most common types of interior data corruptions. A register (buffer) is also provided with this server memory module, which organises the commands sent from the CPU to the memory modules, and ensures that the CPU can access memory in a more practical way. This puts less pressure on the CPU and ensures that tasks can be completed more quickly.
