The ultimate server upgrade This PC3L-12800R single rank server is the ultimate upgrade for your Cisco server. DDR3 technology operates at a high speed and supplies more bandwidth than its DDR predecessor, which allows more data to reach the CPU. This allows more server tasks to be carried out. DDR3 technology also supplies lower voltages, which improves energy efficiency and minimises costs spent running your server. Impressive data security and speed This Cisco product has an ECC (error-correcting code), which maintains optimum server functionality and avoids data corruption by using an algorithm to search for and fix common data errors. A buffer is placed between the DRAM modules, which organises these modules so that the CPUs memory controller can function more easily. The overall server is more efficient as a result.
