Hynix Memory 64GB (1*64GB) 4RX4 PC4-17000P-L DDR4-2133 - 64 GB - DDR4

For enterprise servers and workstations that demand maximum memory capacity per slot without sacrificing signal integrity, the HYNIX HMAA8GL7MMR4N-TF stands apart as a load-reduced DIMM (LRDIMM) engineered to minimise bus loading and enable higher densities. This single 64 GB module operates at 2133 MHz with a PC4-17000P-L rating, delivering the headroom needed for virtualisation, in-memory databases, and large-scale data analytics. Unlike standard registered DIMMs, the LRDIMM architecture uses a memory buffer to isolate the DRAM from the command/address bus, allowing quad-rank configurations to run at full speed while maintaining stability across all four ranks.

Highlights

• 64 GB capacity in one module – maximise memory per channel without populating all slots
• Quad-rank (4Rx4) organisation with x4 chip configuration for deep memory interleaving
• Load-reduced design reduces electrical load, enabling higher speeds and larger capacities
• ECC error correction for mission-critical data integrity in server environments
• 288-pin DDR4 form factor, 1.2 V low-voltage operation for improved energy efficiency
• PC4-17000P-L speed grade, backward compatible with slower DDR4 platforms

In daily use

Deploying the HMAA8GL7MMR4N-TF in a compatible server or workstation immediately expands memory capacity while keeping power and thermal profiles in check. The load-reduced buffer allows the module to present a single load to the memory controller, so even when all four ranks are populated, the system sees a lighter electrical load than a comparable registered DIMM. This is particularly valuable in dense 2U or 4U servers where multiple modules per channel are common. The ECC functionality detects and corrects single-bit errors on the fly, reducing the risk of silent data corruption during long-running workloads. With a CAS latency of CL15 and a 2133 MHz clock, the module balances bandwidth and responsiveness for transactional and analytical applications alike.
