A-Tech Supermicro Certified 16GB DDR4 3200MHz CL22 2Rx8 ECC RDIMM

Certified Supermicro Server Memory

This 16GB DDR4 module carries Supermicro certification for use in validated server platforms. It is built for administrators who need registered ECC memory that meets the vendor's qualified-vendor-list requirements. The dual-rank design suits systems that populate multiple slots per channel. It is not for desktop boards that accept only unbuffered non-ECC DIMMs.

DDR4 3200 Registered Interface Limits

The module runs at the standard 1.20V and delivers a CL22 latency at 3200 MT/s. Registered signalling adds one clock cycle of address/command buffering, which stabilises heavy loads but prevents use in consumer chipsets that lack register support. ECC correction protects data integrity at the cost of a small bandwidth overhead. Populating all slots may force the memory controller to reduce the operating frequency below the rated speed.

2Rx8 Dual-Rank Organisation

The 2Rx8 layout places sixteen 8-bit devices across two ranks, giving the memory controller two independently addressable banks per DIMM. This rank count improves interleaving efficiency on multi-channel server boards but can exceed the rank-per-channel limit of some entry-level platforms. Verify the maximum supported ranks per channel in your system documentation before ordering.
