Frequently Asked Questions
What is the difference between ECC and non-ECC server memory?
ECC (Error Correcting Code) memory automatically detects and corrects single-bit errors in real-time, preventing data corruption in mission-critical applications. Non-ECC memory lacks this protection. For production servers, databases, and virtualization platforms, ECC registered RAM is essential for reliability and uptime.
Is the HMA82GR7JJR8N-VK compatible with my server?
This DDR4-2666MHz ECC registered RDIMM is compatible with servers supporting PC4-21300V-R memory specifications. Check your server's memory support list for compatibility. Registered memory requires server motherboards with registered DIMM slots—it is not compatible with consumer-grade systems.
What does 2Rx8 dual-rank configuration mean?
The 2Rx8 designation indicates two ranks of eight DRAM chips per module. This dual-rank configuration improves memory bandwidth and allows servers to address more memory capacity per slot, enhancing performance in multi-processor environments.
How does registered memory improve server stability?
Registered (buffered) memory includes a register that reduces electrical load on the server's memory controller. This buffering improves signal integrity and allows servers to support higher memory capacities and speeds reliably, making registered DDR4 memory the standard for enterprise infrastructure.
