Capacity and role

This A-Tech module is a 4GB DDR3 registered DIMM built for servers and workstations that require ECC protection. It replaces the Micron MT36JSZF51272PDZ-1GF1DD part number in compatible systems.

Registered ECC and voltage

The registered buffer and ECC circuitry improve data integrity for multi-module configurations. Operation at the standard 1.5V DDR3 voltage ensures compatibility with platforms designed for that specification.

Rank and pin count

The 4Rx8 organisation and 240-pin DIMM form factor determine whether the memory controller can address this module; verify your system supports quad-rank registered DIMMs before ordering.

Questions about this item

Will the registered ECC DIMM need any firmware updates or battery-backed components replaced over its service life?

No firmware or battery-backed parts are present on this registered ECC DIMM; it is a passive DRAM module that requires no scheduled maintenance.

What electrical limit is reached first when the module runs continuously at its rated 1066 MHz speed?

The 1.50 V supply rail defines the operating envelope; sustained loads stay within the standard DDR3 voltage specification without exceeding thermal or current thresholds.

How much heat and fan noise does a single 4 GB stick add to a server chassis running 24/7?

At 1.5 V the module draws only a few watts, adding negligible heat and no audible noise; existing chassis airflow handles it without extra fan speed.
