SK hynix MEM-DR480L-HL01-ER29 32GB (4x8GB) DDR4-2933 CL21 1Rx8 ECC Registered server RAM

Server-grade DDR4 memory kit

This 32GB kit contains four 8GB DDR4-2933 registered DIMMs with ECC and CL21 latency. It is built for servers and workstations that require error correction and signal integrity under sustained loads. The modules operate at 1.20V and conform to the PC4-23400 standard. Desktop boards that cannot use registered ECC memory will not accept these sticks.

Thermals noise and power draw

Each module runs at the standard DDR4 voltage of 1.20V, keeping power draw low for high-density server configurations. Registered buffering reduces electrical load on the memory controller, which helps thermal stability in fully populated slots. No active cooling is included; airflow across the 31.25mm module height is expected from the chassis design. Acoustic impact is negligible because the DIMMs have no moving parts.

Registered ECC and parity checking

The registered design adds a register between the DRAM and the memory controller, enabling parity checking that detects improper addresses or commands. ECC corrects single-bit errors and detects multi-bit errors to protect data integrity in critical workloads. These features replace the need for non-ECC consumer modules in supported platforms. No software utilities or additional accessories are bundled with the kit.
