8GB DDR3L ECC RDIMM for servers

This 8GB DDR3L registered DIMM adds ECC-protected capacity to compatible workstations, servers, NAS units and routers. It runs at 1600MHz with CL11 latency and a low 1.35V operating voltage. The module uses a 1Rx4 organisation and a standard 240-pin form factor. It is built for systems that require registered ECC memory.

Capacity and headroom

An 8GB stick provides a cost-effective step up for memory-constrained multi-user or virtualised workloads. The registered buffer and ECC logic maintain data integrity under sustained load. Systems that need larger per-slot densities or higher frequencies will exceed what this module delivers. Buyers who want more storage or non-ECC desktop memory should look elsewhere.

Build integration

The module fits 240-pin DDR3L slots that explicitly support registered ECC operation. It cannot be mixed with unbuffered DIMMs and will not work in standard desktop platforms. No heat spreader is fitted, leaving clearance for tight server chassis. JEDEC and RoHS compliance ensures a warranty-safe upgrade path.

Questions about this item

Will this 1.35 V DDR3L 1600 RDIMM run with my existing 1.5 V DDR3 1600 RDIMMs?

Mixing 1.35 V DDR3L and 1.5 V DDR3 modules is not recommended; the system will default to the higher voltage and may cause instability or damage.

How can I confirm the module is operating at PC3L-12800 CL11 with ECC active?

Enter the BIOS or use a tool like CPU-Z to verify speed shows 1600 MHz, CAS latency 11, voltage 1.35 V, and ECC/Registered status enabled.

Does the 1Rx4 240-pin RDIMM ship alone or with a heat spreader or installation guide?

The module is supplied without a heat spreader; no brackets, cables or printed guides are included in the package.
