16GB DDR3L 1600 ECC RDIMM for Servers

This 16GB DDR3L 1600 ECC Registered DIMM is built for workstations, servers, NAS systems and routers that require registered memory. It operates at 1.35V with CL11 latency and a 2Rx4 organisation across 240 pins. The module carries JEDEC and RoHS compliance for warranty-safe upgrades.

Replaces Supermicro DDR3L 1600 Registered Modules

It matches the specifications of Supermicro part numbers MEM?DR316L?HL05?ER16, MEM?DR316L?HL06?ER16 and MEM?DR316L?SL02?ER16. The upgrade is worth it when a system needs ECC registered capacity and cannot accept unbuffered DIMMs. Mixing with unbuffered memory is not supported.

Fits 240-Pin DDR3L Registered Slots

The DIMM installs in 240-pin DDR3L slots that support registered ECC operation at 1.35V. It frees capacity headroom for virtualisation or large datasets while keeping power draw low. Buyers who need unbuffered memory or a different DDR generation cannot use this module.

Questions about this item

Will this 240-pin DDR3L RDIMM fit my server's DIMM slots?

Yes, it uses the standard 240-pin DDR3L form factor and 1.35V voltage required by compatible workstation, server, NAS and router platforms.

What is the correct way to install this 2Rx4 registered module, and what mistake should I avoid?

Align the notch with the slot key, press firmly until both retention clips click, and do not mix this registered ECC memory with unbuffered modules in the same system.

Does this 16GB CL11 module require any firmware updates or battery replacements over time?

No, the module has no onboard battery or firmware; it is a passive JEDEC-compliant DRAM component with no scheduled maintenance.
