FAQ
What is the capacity and technology of this memory module?
This AddOn memory module provides 4GB of capacity using DDR3 SDRAM technology. It operates at 1333 MHz speed under the DDR3-1333/PC3-10664 standard, delivering efficient data transfer rates for server and workstation applications requiring this specific memory configuration.
What does Registered ECC mean for this RAM module?
Registered ECC combines two enterprise memory features. The registered design buffers command and address signals to reduce electrical load on the memory controller, supporting higher module densities. ECC (Error-Correcting Code) automatically detects and corrects single-bit memory errors, providing crucial data integrity protection for business-critical systems.
What form factor and pin configuration does this module use?
This module uses a 240-pin RDIMM (Registered Dual In-line Memory Module) form factor. The 240-pin configuration is standard for DDR3 server memory, while the RDIMM designation indicates it includes registered buffers. This physical design ensures compatibility with IBM systems requiring this specific memory slot configuration.
What voltage does this DDR3 memory module operate at?
This module operates at 1.35V, which is a low-voltage specification for DDR3 memory. Compared to standard 1.5V DDR3 modules, the 1.35V operation reduces power consumption and heat generation while maintaining 1333 MHz performance, making it suitable for energy-efficient server deployments.
What is the memory rank and organization of this module?
This module features single-rank organization with x4 data width. Single-rank means all memory chips are accessed simultaneously as one logical rank, while x4 organization refers to the internal data width per chip. This configuration is optimized for memory addressing efficiency in compatible IBM systems.
What warranty and environmental compliance does this memory include?
This AddOn memory module comes with a lifetime limited warranty, providing long-term reliability assurance.
