Server Memory Upgrade

This 8 GB DDR3 registered ECC module runs at 1600 MHz with CL11 latency and 1.50 V operation. It is built as a 1Rx4 RDIMM on a 240-pin DIMM form factor for server and workstation platforms. The Micron chipset base ensures reliable registered buffering for multi-module configurations.

Compatibility Check

Verify that your system accepts DDR3 RDIMM modules at 1600 MHz PC3-12800 with ECC and registered signalling. Confirm the motherboard supports 1Rx4 organisation and 1.50 V DDR3 standard voltage. Cross-reference the Micron part numbers MT18JSF1G72PZ-1G6D1FE and MT18JSF1G72PZ-1G6E1 against your qualified vendor list before ordering.

Thermals and Power

Standard 1.50 V DDR3 voltage keeps power draw within typical registered DIMM limits for this speed grade. Passive cooling via chassis airflow is sufficient; no active heatsink or fan is required on the module itself. Registered buffering adds negligible thermal load compared to unbuffered equivalents in normal server workloads.

Questions about this item

Does the 8GB DDR3 1600MHz ECC RDIMM ship as a single 240-pin module or do I need to buy anything else?

The listing is for one 8GB module (1 x 8GB) in a 240-pin DDR3 DIMM form factor. No extra parts are included; install it directly into a compatible server or workstation slot.

How do I choose between the Micron MT18JSF1G72PZ-1G6D1FE and MT18JSF1G72PZ-1G6E1 versions this module replaces?

Both Micron part numbers share the same 8GB capacity, DDR3 1600MHz speed, CL11 latency, 1.50V voltage, ECC registered design and 1Rx4 rank. This A-Tech module is a compatible equivalent for either part number.

What does the PC3-12800 rating mean for real-world server performance?

PC3-12800 denotes a peak transfer rate of 12,800 MB/s at 1600MHz. With CL11 timing and registered ECC operation, the module delivers stable, error-corrected throughput for typical server and workstation workloads.
