A-Tech Supermicro Certified MEM-DR340L-CL05-ER13 4GB DDR3L 1333 2Rx8 ECC RDIMM 240-Pin server RAM

Certified Supermicro Server Module

This 4 GB DDR3L RDIMM carries the Supermicro MEM-DR340L-CL05-ER13 part number and is validated for Supermicro platforms. It targets administrators upgrading or repairing registered-memory servers that require ECC protection and 1.35 V low-voltage operation. The single-rank Micron chipset delivers 1333 MHz speed with CL9 latency in a 240-pin form factor.

Steady-State Workload Behaviour

Registered buffering and ECC correction maintain data integrity during continuous database, virtualisation or compute tasks. The dual-rank 2Rx8 organisation allows the memory controller to interleave accesses, sustaining throughput on multi-threaded workloads without the error accumulation seen in non-ECC modules. CL9 timing at 1333 MHz provides predictable latency for latency-sensitive services.

Thermals, Noise and Power Draw

Operating at 1.35 V reduces power consumption and heat output compared with standard 1.5 V DDR3, easing cooling requirements in dense chassis. The module runs passively with no moving parts, adding zero acoustic noise to the server environment. Lower voltage also decreases stress on the motherboard voltage regulators during prolonged operation.
