A-Tech 128GB (2x64GB) DDR4 2933 ECC LRDIMM 4Rx4 server RAM

Server-grade DDR4 LRDIMM kit for enterprise

This 128 GB kit contains two 64 GB DDR4 2933 MHz modules built as ECC Load Reduced DIMMs for servers and workstations. Each stick uses a 288-pin form factor and operates at the standard 1.2 V. The quad-rank 4Rx4 organisation is intended for multi-socket platforms that support LRDIMM memory.

Quad-rank 4Rx4 organisation determines platform fit

The modules are 4Rx4 (4DRx4) Load Reduced DIMMs, a configuration that only works in systems explicitly qualified for DDR4 ECC LRDIMM memory. Desktop and laptop platforms cannot use these modules. Verify the server or workstation memory specification list before purchase to confirm 4Rx4 LRDIMM support.

Sustained throughput with ECC and reduced

Load Reduced buffering lowers the electrical load on the memory bus, allowing the quad-rank modules to maintain stable operation at 2933 MHz under continuous heavy workloads. ECC corrects single-bit errors in real time, preserving data integrity during extended compute or virtualisation tasks. The CL21 latency and 1.2 V operation keep power draw predictable while the dual-channel kit layout supports balanced bandwidth across populated channels.
