Server ECC RDIMM Upgrade

This 32 GB DDR3L 1600 CL11 module is a registered ECC RDIMM built for Supermicro X9DR series motherboards. It targets administrators upgrading workstations, servers, NAS boxes or routers that require 1.35 V registered memory. The single DIMM delivers 32 GB in a 4Rx4 configuration and will not work in standard desktop systems or alongside unbuffered modules.

Thermals and Power

Operating at 1.35 V, the DDR3L module draws less power than standard DDR3 parts at the same 1600 MT/s speed. No heat spreader is fitted, so airflow across the PCB handles cooling in typical server chassis. The JEDEC-standard design keeps thermals predictable under sustained ECC workloads.

Build and Installation

The 240-pin DIMM uses a standard RDIMM key notch that matches Supermicro X9DRFF, X9DRFR, X9DRG, X9DRH and X9DRi boards. Registered buffering and on-die ECC require a compatible chipset; mixing with unbuffered DIMMs is not supported. The module is RoHS compliant and covered by OWC's limited lifetime warranty with advance replacement.

Questions about this item

How do I install the 240-pin DDR3L ECC RDIMM into a Supermicro X9DRi motherboard, and which step is often missed?

Align the notch on the module with the slot key, press firmly until both retention clips click, then verify the BIOS detects the full 32 GB at 1600 MHz; the step often missed is seating the module completely so both clips engage.

What maintenance or replacement will this 32 GB DDR3L 1600 CL11 module need during its service life?

No scheduled maintenance is required; if a memory error appears, run a diagnostic and replace the individual RDIMM — ECC corrects single-bit errors, but uncorrectable faults mean the module must be swapped.

What limit appears first when this 1.35 V 4Rx4 registered DIMM runs under sustained load?

The DDR3L 1600 CL11 timing and 1.35 V voltage set the throughput ceiling; sustained workloads will hit the 12800 MB/s bandwidth limit before thermal throttling becomes a factor.
