FAQ
What is the capacity of this memory module?
This Axiom memory module provides 16GB of DDR4 memory capacity. The 16GB size makes it suitable for server applications requiring substantial memory resources for virtualization, database operations, or memory-intensive applications while maintaining ECC protection for data integrity.
What does ECC mean for this memory module?
ECC stands for Error-Correcting Code, a feature that automatically detects and corrects single-bit memory errors. This prevents data corruption and system crashes in server environments where continuous operation and data accuracy are critical. ECC memory is essential for mission-critical applications and enterprise server platforms.
What is the difference between RDIMM and other memory types?
RDIMM (Registered DIMM) includes a register between the memory controller and DRAM chips to buffer command and address signals. This reduces electrical load on the memory controller, enabling support for more memory modules per channel compared to unbuffered DIMMs. RDIMMs are commonly used in servers where higher memory capacities and stability are required.
What speed does this DDR4 memory operate at?
This module operates at 2400 MHz (megahertz) with a CAS latency of CL17. The 2400 MHz speed represents the data transfer rate, while CL17 indicates the number of clock cycles between a read command and data availability. This combination provides balanced performance for server workloads requiring both throughput and responsiveness.
Is this memory compatible with my HP server?
This memory is designed for HP server platforms that support 288-pin RDIMM form factor, DDR4-2400/PC4-19200 memory standard, and registered ECC memory. Compatibility depends on your specific HP server model and its memory specifications. Always verify compatibility with your server's documentation before installation.
What warranty comes with this memory module?
Axiom provides a lifetime limited warranty for this memory module. The warranty covers defects in materials and workmanship for the product's lifetime, offering long-term protection for your server memory investment. This warranty reflects the manufacturer's confidence in the reliability and durability of their server-grade memory products.
