Server DDR3L module for registered memory slots

This 4 GB DDR3L 1333 ECC RDIMM is built for servers and workstations that require registered, error-correcting memory. It runs at 1.35 V low voltage and fits 240-pin DIMM sockets. The module is a compatible replacement for the Kingston KVR1333D3LD8R9S/4G part number.

Low-voltage registered design limits heat and power

Operating at 1.35 V reduces power draw compared to standard 1.5 V DDR3, which helps keep system thermals lower in densely populated memory configurations. Registered buffering adds a clock cycle but lightens the electrical load on the memory controller, contributing to stable operation under sustained workloads.

Major-brand chips tested for ECC reliability

The module uses major-brand DRAM chips and undergoes quality-assurance testing to verify ECC function and registered signalling. This validation aims to deliver dependable error correction and signal integrity for mission-critical server deployments.

Questions about this item

How do I install this 240-pin DDR3L RDIMM and what step is often missed?

Power off the server, open the chassis, align the notch on the 240-pin module with the slot key, press firmly until both retention clips click, then verify in BIOS that the 1.35V voltage and ECC registered mode are recognised.

What maintenance or replacement will this 4GB DDR3L 1333 module need over time?

No routine maintenance is required; if a memory error appears, reseat the module or replace the single 4GB stick — there are no batteries, fans or firmware to service.

What limit appears first when this CL9 1.35V RDIMM runs sustained workloads?

The 1333 MT/s data rate and CL9 latency set the throughput ceiling; sustained heavy loads will hit that bandwidth limit before the 1.35V thermal envelope becomes a constraint.
