Exceptional server performance Provide your IBM system with an ideal server upgrade by using this PC3-12800R server memory module. This DDR3 provides more bandwidth than its DDR predecessor, which permits more data to reach your CPU and therefore increases the productivity of your system. A lower voltage means that less power is being used to run your server, which reduces operational costs and improves energy efficiency. Impressive data security The ECC (error-correcting code) in this product creates a fortified layer of protection against system crashes and failures. It does this by constantly scanning your system in search of minor errors and faults, which it corrects, thereby preventing internal data corruption. There is also a register (buffer), which increases the productivity of your server over time by making it easier for the CPU to access memory modules. Wondering if your server is compatible with this IBM product? Just drop us a line and well be happy to help!
