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.

Questions about this item

How much heat and power does the 1.35V DDR3L module draw when the server runs continuously?

The DDR3L 1333 module operates at 1.35 volts, which is lower than standard DDR3 voltage, reducing both power draw and heat output during all-day workloads.

What must the motherboard provide for this 240-pin RDIMM to function?

The board needs a DDR3L-registered DIMM slot that supports 1333 MHz PC3L-10600, ECC, and 2Rx8 organisation.

Will this 4GB DDR3L 1333 stick work alongside older 1.5V DDR3 modules I already have?

Mixing 1.35V DDR3L with 1.5V DDR3 forces the memory controller to run at the higher voltage, so the low-voltage advantage is lost and stability cannot be guaranteed.
