SK hynix HMA82GR7DJR4N-XN 16GB DDR4-3200 ECC Reg CL22 1Rx4 server RAM

16 GB DDR4-3200 ECC Registered Module

This 16 GB DDR4-3200 module is built for servers and workstations that require registered ECC memory. It operates at 3200 MHz with a CAS latency of CL22 and uses a 288-pin form factor. The single-rank 1Rx4 organisation helps keep electrical loading low on populated channels.

Suited for Registered ECC Platforms Only

This module fits systems designed for registered ECC DDR4 memory with 288-pin slots. It will not work in desktop or laptop boards that accept only unbuffered non-ECC memory. Buyers who need unbuffered modules or a different capacity should look at other parts.

Registered ECC with Single-Rank Layout

The registered ECC design adds a buffer that reduces signal load on the memory controller, while the single-rank 1Rx4 layout allows higher population densities on supported platforms. This combination decides whether the module is compatible with a given server board.
