FAQ
What type of memory module is this?
This is a 4GB DDR4 Registered ECC RDIMM (Registered Dual In-line Memory Module) designed for server use. It features 288 pins, operates at 2133 MHz with CL15 latency, and includes both error correction (ECC) and registered signal processing for enterprise-grade reliability.
What does Registered ECC mean for server memory?
Registered ECC combines two important server memory features. ECC (Error Correcting Code) detects and corrects single-bit memory errors to prevent data corruption. Registered design includes a register between the memory controller and DRAM chips to reduce electrical load, improving signal stability when multiple modules are installed. This combination enhances both data integrity and system stability in server environments.
What is the compatibility of this memory module?
This module is designed as a compatible replacement for IBM 46W0783 server systems. It uses the standard 288-pin RDIMM form factor with DDR4-2133/PC4-17000 specifications. Compatibility depends on specific server models supporting registered DDR4 memory at 2133 MHz with 1.2V operation. Always verify compatibility with your server manufacturer's specifications before installation.
What is the difference between RDIMM and other memory types?
RDIMM (Registered DIMM) includes a register between the memory controller and DRAM chips to reduce electrical load, enabling more stable operation with multiple modules. This differs from UDIMM (Unbuffered DIMM) which has no register and is typically used in desktop systems, and LRDIMM (Load Reduced DIMM) which includes additional buffering for very high-density configurations. RDIMMs offer a balance of stability and performance for mainstream server applications.
What does single-rank x8 configuration mean?
Single-rank means all memory chips on the module are accessed simultaneously as one logical rank. The x8 designation refers to the organization of memory chips with 8-bit data width per chip. This configuration provides efficient memory access patterns and is commonly used in server memory modules. The combination affects how the memory controller addresses the module and can influence performance in multi-module configurations.
What warranty coverage does this memory module include?
This AddOn memory module includes a lifetime limited warranty. This warranty typically covers defects in materials and workmanship for the life of the product when used under normal conditions in accordance with the manufacturer's specifications. The lifetime warranty provides long-term assurance for server infrastructure investments, particularly important for business environments with extended equipment lifecycles.
