32GB DDR3 ECC Registered DIMM

This module provides 32GB of DDR3 server memory in a single 240-pin registered DIMM. It operates at 1600MHz with a CL11 latency and 1.5V voltage. The 4Rx4 ECC registered design targets data integrity for workstations, servers and NAS systems.

Requires registered ECC memory slots

The module fits 240-pin DDR3 slots that support registered ECC operation. It cannot be mixed with unbuffered memory and will not function in standard desktop platforms. Installing it frees additional slots for further registered ECC expansion where the platform allows.

Suits administrators upgrading compatible servers

Buyers maintaining JEDEC-compliant DDR3 infrastructure gain a warranty-safe capacity increase. Those needing unbuffered desktop memory, non-ECC modules, or different DDR generations must select alternative products.

Questions about this item

How does the 1.5V voltage affect sustained power draw under load?

The module operates at 1.5V, the standard voltage for DDR3 registered DIMMs, so power consumption scales with the 1600 MHz data rate and 4Rx4 organisation rather than any elevated voltage.

What thermal output should I expect when the DIMM runs continuously in a populated server chassis?

With no heat spreader fitted, the 32 GB module relies on chassis airflow across the 240-pin PCB; registered ECC operation at CL11 and 1.5V keeps heat within normal DDR3 limits for dense 4Rx4 configurations.

Which slot type and memory controller features must my system provide for this module to function?

A 240-pin DDR3 socket wired for registered ECC operation is required; the platform must support 4Rx4 load-reduced signalling and 1.5V supply, typical of workstation, server, NAS or router mainboards.
