SK hynix HMABAGR7A2R4N-XS 128GB DDR4-3200 ECC Registered Quad Rank Server RAM

128GB DDR4-3200 ECC Registered Server Memory

This 288-pin DDR4 SDRAM module delivers 128GB of capacity at 3200MHz with PC4-25600 bandwidth. It is built for servers and workstations that require registered ECC memory for data integrity and high-density configurations. The quad-rank design supports large memory footprints in compatible multi-socket platforms.

Registered ECC Buffering and Quad-Rank Architecture

The registered buffer reduces electrical load on the memory controller, allowing higher module counts per channel in enterprise systems. On-die ECC detects and corrects single-bit errors to maintain uptime in mission-critical workloads. The 2Rx4 quad-rank organisation enables this 128GB density within a single DIMM slot.

CAS Latency 1.1 Timing Specification

A CAS latency of 1.1 cycles at DDR4-3200 defines the module's access timing for the memory controller. Systems must support this timing parameter to operate the module at its rated 3200MHz speed. Buyers verifying motherboard QVL entries or BIOS memory profiles should match this latency value to ensure compatibility.
