Server Memory Upgrade

This A-Tech 4 GB DDR3 module is built for server and workstation systems that require registered ECC memory. It replaces the Micron MT18JSF51272PZ-1G6 part and installs in a standard 240-pin DIMM slot.

4 GB Capacity and DDR3 1600 Speed

The single-rank 1Rx4 design runs at 1600 MHz (PC3-12800) with CL11 latency at 1.50 V. It handles everyday server workloads and virtualisation hosts within its 4 GB limit; larger datasets or memory-heavy databases will exhaust the capacity quickly.

Direct Replacement for Micron MT18JSF51272PZ-1G6

Use this module when a compatible registered ECC DIMM is needed to restore or expand a qualified platform. The jump is worth it when the system currently has empty slots or lower-capacity modules and the workload fits within 4 GB per DIMM.

Questions about this item

Will this DDR3 1600 RDIMM run with my existing CL9 modules at 1.5V?

Mixing CAS latencies forces the system to run at the slowest timing; both this CL11 stick and your CL9 modules will operate at CL11 while sharing the standard 1.5V DDR3 voltage.

How can I confirm the ECC RDIMM is registered and error-correcting after installation?

The BIOS memory information screen will show ECC enabled and the module type listed as Registered (RDIMM), confirming both functions are active.

Does the 240-pin DIMM ship alone or with a heat-spreader and installation guide?

The package contains the single 4GB 1Rx4 RDIMM only; no heat-spreader, manual or additional accessories are included.
