Frequently Asked Questions
What is an RDIMM and why do I need it?
An RDIMM (Registered DIMM) includes a register that buffers the command and address signals, reducing electrical load on the memory controller. This enables servers to support larger memory configurations with greater stability — essential for enterprise environments running mission-critical applications.
Is this memory compatible with my server?
This Samsung DDR4-2666 RDIMM is compatible with enterprise servers that support DDR4 memory at 2666 MHz speeds. Check your server's specifications or contact our support team to verify compatibility with your specific system.
What does ECC memory do?
ECC (Error-Correcting Code) memory automatically detects and corrects single-bit memory errors in real-time. This is critical for servers where data integrity cannot be compromised, preventing silent data corruption and system crashes.
How does 2RX4 dual-rank architecture improve performance?
The 2RX4 configuration provides two ranks of memory on each side of the module, increasing memory density and allowing the memory controller to interleave access patterns. This improves overall system performance and throughput for data-intensive workloads.
