FAQ
What type of memory module is the AddOn 726717-S21-AM?
The AddOn 726717-S21-AM is a 4GB DDR4 registered ECC RDIMM (Registered Dual In-line Memory Module) designed for server use. It operates at 2133 MHz with CL15 latency and features single rank x8 organization with 288-pin configuration. This module utilizes registered signal processing with error checking and correction (ECC) for enhanced data integrity in server environments.
What does 'registered ECC' mean for this memory module?
Registered ECC refers to two key server memory features. 'Registered' means the module includes a register (or buffer) between the memory controller and DRAM chips, which reduces electrical load on the memory controller and allows for greater memory capacity in servers. 'ECC' (Error Checking and Correction) enables the module to detect and correct single-bit memory errors, preventing data corruption and system crashes. Together, these features provide the stability and reliability required for enterprise server applications.
What is the operating speed and latency of this memory?
This memory module operates at 2133 MHz with a CAS latency of CL15. The 2133 MHz speed represents the data transfer rate, while CL15 indicates the number of clock cycles between a memory controller request and data availability. These specifications provide responsive performance for server workloads while maintaining compatibility with server platforms designed for DDR4-2133 memory.
Is this memory module compatible with my HP server?
This module is factory original compatible for HP servers that support 4GB DDR4-2133MHz registered ECC RDIMMs. Compatibility depends on your specific server model and its memory requirements. Check your server documentation or manufacturer specifications to verify compatibility before purchase. The module uses a 288-pin RDIMM form factor, which is standard for server memory slots designed for registered DIMMs.
What is the difference between RDIMM and other memory form factors?
RDIMM (Registered DIMM) includes a register between the memory controller and DRAM chips, which reduces electrical load and supports higher memory capacities in servers. This differs from UDIMM (Unbuffered DIMM), which has no register and is typically used in desktop systems, and LRDIMM (Load Reduced DIMM), which includes both a register and data buffer for even higher capacity server configurations. The 288-pin RDIMM form factor is specifically designed for server memory slots requiring registered memory.
What warranty coverage does this memory module include?
The AddOn 726717-S21-AM memory module includes a lifetime limited warranty. This warranty covers defects in materials and workmanship for the lifetime of the product. The module is manufactured in China and is not TAA (Trade Agreements Act) compliant. For warranty service or support, contact the manufacturer or authorized reseller with proof of purchase.
