Server ECC RDIMM Module

This A-Tech module is a 4GB DDR3L registered DIMM built for servers and workstations that require error-correcting memory. It operates at 1333MHz with a CL9 latency and runs at the low 1.35V DDR3L voltage to reduce power draw in compatible platforms.

Compatibility and Use Cases

The module suits administrators upgrading or repairing systems that accept DDR3L 1333MHz PC3L-10600 ECC RDIMMs with a 2Rx4 organisation. It is not intended for desktop boards that only support unbuffered non-ECC memory or for platforms that require a different voltage, speed or form factor.

Deciding Specification

The registered ECC design combined with DDR3L 1.35V operation is the single specification that determines whether this part will function in a given server; the system must explicitly support registered error-correcting DDR3L DIMMs at this voltage.

Questions about this item

How much heat does the 1.35V DDR3L module generate under continuous server load?

The 1.35V DDR3L voltage reduces power draw compared to standard 1.5V DDR3, lowering heat output during all-day operation in registered DIMM configurations.

What motherboard slot and chipset support are required for this 240-pin ECC RDIMM?

A server or workstation motherboard with DDR3 240-pin registered DIMM slots and ECC support in the chipset is required; verify your system manual for qualified memory lists.

Can this CL9 1333MHz registered module run alongside existing CL9 1333MHz unbuffered DIMMs?

No — registered ECC RDIMMs and unbuffered DIMMs use different signalling and cannot be mixed in the same system; all slots must use registered modules.
