FAQ
What type of memory is this AddOn 815100-B21-AM module?
This is a 32GB DDR4-2666MHz Registered ECC RDIMM (Registered Dual In-Line Memory Module) with dual-rank x4 design. It features error-correcting code (ECC) for data integrity and registered signal processing for server compatibility, operating at 1.2V with CL17 latency in a 288-pin DIMM form factor.
What does Registered ECC mean for server memory?
Registered ECC combines two server memory technologies: ECC (Error-Correcting Code) detects and corrects single-bit memory errors automatically, while registered signal processing includes a register that buffers address and control signals. This combination improves stability and allows for higher memory capacities in server systems compared to unbuffered memory.
What is the difference between RDIMM and UDIMM memory?
RDIMM (Registered DIMM) includes a register between the memory controller and DRAM chips that buffers signals, allowing for greater memory capacity and stability in server systems. UDIMM (Unbuffered DIMM) lacks this register and is typically used in desktop systems. This AddOn module is an RDIMM, making it specifically designed for server platforms that require registered memory architecture.
What server applications benefit from this 32GB DDR4-2666MHz memory?
This memory module is ideal for server applications requiring high capacity and reliability, including database servers, virtualization hosts, application servers, and computational workloads. The 32GB capacity supports increased virtual machine density, while the ECC protection ensures data integrity for mission-critical operations in enterprise and data center environments.
What does dual-rank x4 design mean for memory performance?
Dual-rank means the memory module has two independent sets of memory chips that can be accessed separately, improving efficiency by allowing the memory controller to work with one rank while the other refreshes. The x4 designation refers to the data width of individual memory chips (4 bits). This configuration is common in server memory and helps balance performance with capacity in registered ECC modules.
Is this memory module compatible with my existing server?
This AddOn 815100-B21-AM module requires a server motherboard that supports registered ECC DDR4 memory with 288-pin DIMM slots and is compatible with 2666 MHz speed. You should verify your server's specifications support registered ECC memory, DDR4 technology, and 2666 MHz operating speed before purchase, as server memory compatibility depends on specific platform requirements.
