Frequently Asked Questions
What is an RDIMM and why do I need it?
An RDIMM (Registered DIMM) is specifically designed for server environments. The registered buffer reduces electrical load on the memory controller, enabling support for higher capacities and more DIMM slots per server. This DDR5-4800 RDIMM is ideal for multi-socket systems requiring maximum memory density.
Does this memory module support ECC?
Yes, this Samsung module includes full ECC (Error-Correcting Code) support. ECC memory automatically detects and corrects single-bit errors, making it essential for enterprise servers, data centers, and any environment where data reliability cannot be compromised.
What servers are compatible with DDR5-4800 RDIMM memory?
This PC5-38400 DDR5-4800 RDIMM is compatible with enterprise servers supporting DDR5 technology, including latest-generation Intel Xeon and AMD EPYC platforms. Verify your server's memory specifications before purchase to ensure compatibility.
What does 4Rx4 configuration mean?
The 4Rx4 configuration indicates quad-rank memory with four ranks per side. This design maximizes capacity while maintaining stability in demanding server environments, providing superior performance for virtualization and high-throughput applications.
