FAQ
What is the memory capacity and technology of this module?
This module offers 8GB of capacity using DDR4 SDRAM technology. DDR4 provides improved data transfer rates and lower power consumption compared to previous generations, making it suitable for modern computing systems that require efficient memory performance for applications like multimedia editing, gaming, and data processing.
What speed and latency does this DDR4 memory operate at?
It operates at 2666 MHz with a CAS latency of CL17. This combination delivers a balance of high bandwidth and low latency, enabling quick data access for tasks such as web browsing, software multitasking, and graphics rendering, which helps minimize system bottlenecks during intensive operations.
Is this memory module ECC or non-ECC?
This is a non-ECC (Error-Correcting Code) module. Non-ECC memory does not include advanced error correction features, making it ideal for standard desktop PCs and entry-level servers where cost-effectiveness and performance are prioritized over maximum data integrity. It is suitable for environments where occasional memory errors are acceptable.
What form factor and pin count does this module have?
It uses a DIMM form factor with 288 pins. This is the standard physical design for desktop and server memory modules, ensuring compatibility with most modern motherboards that support DDR4 technology. The 288-pin interface provides the necessary connections for data transfer and power management.
What devices is this memory compatible with?
This module is compatible with desktop PCs and servers that support DDR4-2666 unbuffered non-ECC memory. It is designed for systems where the motherboard specifications match the 288-pin DIMM form factor, 1.2V voltage, and unbuffered architecture. Always verify your system's compatibility before purchase.
What are the advantages of unbuffered memory?
Unbuffered memory, like this module, offers lower latency compared to buffered or registered memory because it communicates directly with the memory controller without intermediate buffering. This results in faster data access times, making it ideal for applications where responsiveness is critical, such as gaming, real-time data processing, and general-purpose computing.
