Server-grade capacity for ECC workloads

This 32 GB DDR3L registered DIMM delivers error-correcting memory for servers and workstations that require data integrity. The 4Rx4 organisation and CL9 latency suit multi-socket platforms running virtualisation or database tasks. It operates at 1.35 V, reducing power draw compared with standard DDR3 modules.

Fits 240-pin registered DIMM slots

The module uses the 240-pin DDR3 form factor and requires a motherboard that supports registered ECC memory and DDR3L voltage. It replaces Micron MT72KSS4G72PZ-1G4N1, MT72KSZS4G72PZ-1G4 and MT72KSZS4G72PZ-1G4E2 parts. Systems limited to unbuffered or non-ECC DIMMs cannot use this module.

Low-voltage operation aids thermal headroom

At 1.35 V the DIMM generates less heat than 1.5 V DDR3 equivalents, helping densely populated memory channels stay cooler under sustained load. Registered buffering reduces electrical loading on the memory controller, contributing to stable operation in fully populated configurations.

Questions about this item

How does the 4Rx4 rank configuration affect maximum capacity on a single memory channel?

The 4Rx4 organisation counts as four logical ranks; most server chipsets limit a channel to eight ranks, so two of these 32 GB modules will reach that limit.

What thermal load should I expect from the 1.35 V DDR3L registered DIMM during continuous operation?

At 1.35 V the module draws less power than standard 1.5 V DDR3, reducing heat output; registered buffering adds minimal overhead, so airflow designed for typical RDIMMs is sufficient.

Which motherboard slot and chipset features are required for this 240-pin DDR3L ECC RDIMM to function?

A DDR3 240-pin DIMM slot with registered-memory support and ECC capability in the chipset is mandatory; consumer boards without those features will not POST with this module.
