FAQ
What is the capacity and speed of this memory module?
This Axiom memory module provides 16GB of capacity operating at 2933 MHz speed. It uses DDR4 SDRAM technology with a PC4-23466 classification, delivering a peak transfer rate of 2933 million transfers per second for responsive server performance.
What does ECC mean for this server memory?
ECC stands for Error-Correcting Code, a technology that automatically detects and corrects single-bit memory errors. This prevents data corruption and system crashes in mission-critical server environments where data integrity is essential for business operations.
What is the difference between registered and unbuffered memory?
Registered memory (RDIMM) includes a register between the memory controller and DRAM chips that reduces electrical load, enabling support for more modules and higher capacities. Unbuffered memory (UDIMM) connects directly without this buffer, typically used in consumer systems with fewer modules.
What is the form factor and pin count of this module?
This module uses the RDIMM (Registered Dual In-line Memory Module) form factor with 288 pins. The physical dimensions are standard for server memory, approximately 133.35 mm in length, designed for installation in server motherboards with 288-pin DDR4 slots that support registered memory.
What is the CAS latency and operating voltage?
This memory module operates with CL21 CAS latency, indicating 21 clock cycles between receiving a command and data availability. It runs at 1.20V, which is the standard voltage for DDR4 memory, providing power-efficient operation compared to previous DDR generations.
Is this memory compatible with HP servers?
Yes, this Axiom P19041-B21-AX memory module is designed for compatibility with HP server platforms that support registered DDR4 memory. The 288-pin RDIMM form factor and registered ECC design match the requirements of HP ProLiant and similar server systems using compatible memory architectures.
