8GB DDR4 2400 ECC RDIMM CL17 1Rx8 registered server memory for SuperMicro systems
This 8 GB DDR4 module is built for SuperMicro server and workstation platforms that require registered ECC memory. It operates at 2400 MHz with a CL17 latency and a 1.20 V supply. The single-rank 1Rx8 organisation fits standard 288-pin RDIMM slots in compatible systems.
Registered buffering and ECC correction keep data integrity high while the 1.20 V DDR4 voltage limits power draw per module. Passive components and no heat spreader mean silent running inside chassis with managed airflow. Typical idle and light-load thermals stay close to ambient server inlet temperatures.
Modules are stress tested under sustained workloads to verify signal integrity and error correction across extended periods. The registered design reduces electrical loading on the memory controller during continuous throughput. This makes the kit suitable for virtualisation hosts, database nodes and other 24/7 server roles.

Align the notch on the module with the slot key, press firmly until both side clips click, and confirm the system registers 8 GB at 2400 MT/s in BIOS; the step often missed is seating the module fully so both clips engage automatically.
No routine maintenance is required; the module has no heat spreader or moving parts, and ECC error correction handles transient faults internally.
The CAS latency of 17 cycles at 2400 MT/s sets the timing ceiling; bandwidth and capacity remain constant, so latency is the first constraint under heavy sustained workloads.
