FAQ
What is the capacity and configuration of this memory module?
This is a single 16GB DDR4 memory module, providing 16 gigabytes of memory in one stick. The 1x16GB configuration allows for flexible memory expansion in systems with available DIMM slots, making it suitable for both adding capacity to existing servers or building new configurations with specific memory requirements.
What does ECC mean and why is it important for server memory?
ECC stands for Error-Correcting Code, a technology that detects and corrects single-bit memory errors automatically. In server environments, ECC is crucial because it prevents data corruption and system crashes that can occur from memory errors during continuous operation. This ensures higher reliability and data integrity for mission-critical applications and server workloads.
What is the difference between UDIMM and other memory form factors?
UDIMM (Unbuffered Dual In-line Memory Module) is a standard memory form factor that doesn't include a register or buffer between the memory controller and DRAM chips. This results in lower latency compared to registered (RDIMM) memory, making UDIMM suitable for applications where quick memory access is prioritized. The 288-pin UDIMM design is commonly used in server and workstation motherboards that support unbuffered memory.
What systems is this memory module compatible with?
This module is specifically compatible with HPE 10 Series ProLiant Gen9 Entry Servers. It uses a standard 288-pin UDIMM form factor operating at DDR4-2400 speed. While designed for HPE systems, it may work in other servers with compatible specifications, but always verify your motherboard's memory requirements before installation to ensure proper compatibility and performance.
What is the significance of the 2400 MHz speed and CL17 latency?
The 2400 MHz speed indicates how many data transfers the memory can perform per second, with higher numbers generally meaning better performance for memory-intensive tasks. CL17 (CAS Latency 17) represents the number of clock cycles needed to access a specific column of data, with lower numbers indicating faster response times. The combination of 2400 MHz with CL17 latency provides balanced performance suitable for server applications requiring both bandwidth and responsiveness.
How does DDR4 technology benefit server memory performance?
DDR4 (Double Data Rate 4) SDRAM offers several advantages over previous generations including higher data transfer rates, increased bandwidth, improved power efficiency with lower operating voltage, and greater memory density per module. For servers, this translates to better performance for virtualization, database operations, and other memory-intensive workloads while maintaining reliability through technologies like ECC that are commonly implemented in DDR4 server memory modules.
