8GB DDR3 1600MHz ECC RDIMM

This 8GB registered DIMM uses Samsung chips and runs at DDR3 1600MHz with CL11 latency. It is certified for Supermicro systems and carries the MEM-DR380L-SL01-ER16 part number. The module is built for servers and workstations that require error-correcting registered memory.

Thermals noise and power draw

Operating at the standard 1.5V DDR3 voltage, the module draws typical power for an 8GB registered stick. Passive cooling through the server chassis airflow keeps temperatures within normal limits. No active cooling or additional fan noise is introduced by the memory itself.

Sustained load behaviour

The dual-rank 2Rx4 organisation helps maintain bandwidth during extended workloads. ECC registration adds a clock cycle of buffering, which stabilises the signal under continuous read and write cycles. The module is tested for reliable operation in 24/7 server environments.

Questions about this item

How do I install this 240-pin DDR3 RDIMM in a Supermicro server and which step is often missed?

Power down the server, open the chassis, align the module key notch with the slot, press firmly until both retention clips click, then verify the system BIOS reports the full 8 GB at 1600 MHz; the step often missed is enabling ECC in the BIOS after the physical install.

What maintenance or replacement will this Samsung ECC RDIMM need over its service life?

No scheduled maintenance is required; the module is tested for lifetime reliability, so replacement is only needed if a memory diagnostic reports uncorrectable ECC errors or the server fails to POST with the DIMM seated.

What is the first limit reached when this CL11 1.50 V registered DIMM runs sustained workloads?

The thermal and voltage envelope of DDR3 at 1.50 V and CL11 latency defines the sustained performance ceiling; the registered buffer adds minor latency but prevents signal degradation, so the memory controller’s maximum supported bandwidth at 1600 MHz is the limiting factor.
