FAQ
What is the difference between ECC and non-ECC memory?
ECC (Error-Correcting Code) memory includes additional circuitry that detects and corrects single-bit memory errors automatically. This is essential for server and workstation environments where data integrity is critical, as it prevents system crashes and data corruption that can occur with standard non-ECC memory. Non-ECC memory lacks this error correction capability and is typically used in consumer desktop computers.
What does 'Registered' mean in memory modules?
Registered memory (also called buffered memory) includes a register between the memory controller and the DRAM modules that helps stabilize electrical signals. This allows systems to support more memory modules while maintaining signal integrity, which is particularly important in servers with large memory capacities. Registered memory is slower than unbuffered memory but provides greater stability for enterprise applications.
Is this memory compatible with my Dell PowerEdge server?
This Kingston module is validated for compatibility with specific Dell PowerEdge servers including the R440, R540, C6420, R640, R740, R740xd, R940, and T440 models. It is also compatible with Dell Precision 7820 Tower and 5820 workstations. Always verify your specific system's memory requirements before purchasing, as server memory compatibility depends on the memory controller, BIOS version, and existing memory configuration.
Can I mix this module with other memory in my server?
For optimal performance and stability, it is recommended to use identical memory modules with matching specifications (capacity, speed, latency, and features) in server configurations. Mixing different memory types, speeds, or capacities can lead to system instability or the memory running at the speed of the slowest module. Consult your server documentation for specific memory configuration guidelines.
What is the advantage of DDR4 over DDR3 memory?
DDR4 memory offers several advantages over DDR3 including higher data transfer rates (this module operates at 2666MHz compared to typical DDR3 speeds of 1333-1866MHz), lower operating voltage (1.20V vs. 1.35V or 1.50V for DDR3), improved signal integrity, and higher density modules. DDR4 also introduces new features like bank groups that improve efficiency, making it better suited for modern server and workstation platforms.
What does CL19 latency mean for performance?
CL19 refers to the CAS (Column Address Strobe) latency, which is the number of clock cycles between when a memory controller requests data and when that data is available. A CL19 rating at 2666MHz represents the timing characteristics optimized for server applications where stability and error correction are prioritized over ultra-low latency. While lower CAS numbers generally indicate faster response times, server memory often uses slightly higher latencies to ensure reliability in multi-module configurations.
