A-Tech 8GB DDR3 ECC RDIMM

This A-Tech module is an 8GB DDR3 1866MHz ECC Registered DIMM built as a compatible replacement for Micron MT18JSF1G72PDZ-1G9P1. It runs at 1.50V with CL13 latency and uses a 2Rx8 rank configuration on a 240-pin DIMM form factor. The module targets server and workstation systems that require registered ECC memory for data integrity.

Suited for DDR3 registered ECC platforms

It suits administrators upgrading or repairing servers and workstations that specifically accept DDR3 1866MHz ECC RDIMM modules. It is not for desktop PCs or laptops that use unbuffered non-ECC memory, nor for systems limited to lower DDR3 speeds or different pin counts. Buyers needing larger single-module capacities or newer DDR generations must select different memory.

8GB capacity for moderate workloads

The 8GB capacity handles typical virtualization hosts, database buffers and multi-user application servers with comfortable headroom. Memory-intensive tasks such as large in-memory analytics, heavy container densities or high VM counts will exhaust this module quickly. Each stick provides a single 8GB rank pair, so total system capacity depends on available DIMM slots.

Questions about this item

What motherboard slot does the 240-pin DDR3 DIMM need to fit this A-Tech module?

The module uses the standard DDR3 DIMM 240-pin form factor, so your motherboard must provide a DDR3 DIMM slot that accepts registered ECC memory.

Will this registered ECC DDR3 1866 MHz module run in a system that only supports unbuffered non-ECC DDR3?

No — registered ECC modules require a chipset and BIOS that explicitly support registered operation and ECC; they will not function in consumer boards limited to unbuffered non-ECC DDR3.

How can I confirm the module is recognised at 1866 MHz with ECC active after installation?

Enter the BIOS or use a tool such as CPU-Z or dmidecode; the memory should report 1866 MHz (PC3-14900), CL13, 1.5 V, and show ECC type as registered.
