Server Memory Upgrade

This 4 GB DDR3 1600 MHz registered ECC module is built for server and workstation platforms that require error-correcting memory. It replaces the Micron MT18JSF51272PDZ-1G6M1 part and fits 240-pin DIMM slots. The dual-rank 2Rx8 organisation suits systems designed for registered DIMMs.

Thermals and Power

Operating at the standard DDR3 voltage of 1.5 V, the module draws typical power for its class and runs within normal server thermal envelopes. Registered buffering reduces electrical load on the memory controller, helping stability under sustained workloads. No additional cooling beyond standard chassis airflow is required.

Compatibility and Assurance

Every unit undergoes quality-assurance testing before shipment to verify reliable operation in qualified systems. Buyers must confirm their platform supports DDR3 registered ECC DIMMs, as this module will not work in consumer desktop boards or laptops that require unbuffered non-ECC memory.

Questions about this item

How do I install this 240-pin DDR3 RDIMM and what step do people often get wrong?

Align the notch on the module with the key in the 240-pin DDR3 slot, press firmly until both retention clips click shut, and ensure the registered module is seated in a slot that supports registered DIMMs — the step most often missed is verifying the motherboard accepts RDIMMs before installation.

What maintenance or replacement will this ECC RDIMM need later?

No routine maintenance is required; the module either continues operating or develops correctable errors that ECC handles, and replacement is only needed if uncorrectable errors appear or system diagnostics report a persistent fault.

What limit appears first when this 1.50V CL11 module runs under sustained load?

The DDR3 1600 CL11 timing and 1.50V voltage set the performance ceiling; under sustained load the memory controller reaches its maximum throughput at these specifications before thermal throttling becomes a factor.
