FAQ
What is the capacity and speed of this AddOn memory module?
This AddOn memory module provides 16GB of capacity with a speed of 2666 MHz. It complies with the DDR4-2666/PC4-21300 standard, delivering balanced performance for server and workstation applications where both capacity and speed contribute to overall system responsiveness.
What does Registered ECC mean for this memory module?
Registered ECC combines two important features: registered signal processing and error-correcting code. The registered design includes a register on the module that buffers address and command signals, improving signal integrity in systems with multiple memory modules. ECC automatically detects and corrects single-bit memory errors, enhancing data reliability and reducing system crashes in critical computing environments.
What is the form factor and pin count of this module?
This module uses a 288-pin DIMM (Dual In-line Memory Module) form factor. The 288-pin configuration is standard for DDR4 memory modules designed for desktop and server systems, ensuring proper electrical connections and physical compatibility with corresponding motherboard memory slots.
What does dual-rank architecture provide?
Dual-rank architecture organizes the memory chips on the module into two independent sets or ranks that can be accessed alternately. This design improves memory access efficiency by allowing the memory controller to work with one rank while the other refreshes or prepares data, reducing latency and increasing effective bandwidth in supported systems compared to single-rank modules of similar specifications.
What is the CAS latency and operating voltage?
This memory module has a CAS latency of CL17 and operates at 1.2V. The CL17 latency indicates the number of clock cycles required to access a column of data once the row is open, with lower numbers generally indicating faster response. The 1.2V operating voltage represents DDR4's improved power efficiency compared to previous DDR generations, reducing energy consumption in memory-intensive systems.
What types of systems is this memory module compatible with?
This memory module is designed for PC and server systems that support registered DDR4 memory with ECC functionality. Compatibility depends on specific motherboard and chipset support for registered ECC modules at 2666 MHz speed. Always verify compatibility with your system's documentation before installation, as not all systems support registered memory or ECC features.
