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.

Highlights

  • ECC protection guards data integrity with registered DDR3 1600MHz operation
  • 8GB capacity expands server workloads using a single 1Rx4 module
  • CL11 latency and 1.50V voltage deliver stable PC3-12800 performance
  • Micron chipset compatibility replaces MT18JSF1G72PZ-1G6D1FE and MT18JSF1G72PZ-1G6E1 parts

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.
