The IBM Memory Module is designed expressly for enterprise-level applications, including servers, with a 4 GB capacity. As a DDR3 memory module, its rated for 1333 MHz with CL9 latency, making it appropriate for reliability-centered performance. It is an ECC registered memory module, thereby enhancing memory reliability and overall system stability. This memory module comes with a form factor of 240 pin DIMM and operates at a 1.35 V, making it low voltage and economical in terms of energy use, particularly in power sensitive environments. Its very low profile (VLP) dual rank design allows compatibility with systems having dense spatial constraints. This memory module will upgrade the server memory and enhance the system performance for reliable performance demanded memory modules.
