A-Tech 4GB DDR3L 1600 ECC UDIMM 1Rx8 1.35V 240-Pin for Micron MT9KSF51272AZ-1G6 Server Memory

4GB DDR3L ECC UDIMM for servers

This 4GB DDR3L 1600 ECC UDIMM module suits servers and workstations that require error-correcting unbuffered memory. It runs at 1.35V low voltage and uses a 240-pin DIMM form factor with a single-rank 1Rx8 organisation. The kit is a direct replacement for Micron MT9KSF51272AZ-1G6 modules.

DDR3L 1600 speed and voltage limits

The module operates at 1600 MT/s with a PC3L-12800 data rate and CL11 latency. DDR3L voltage of 1.35V reduces power draw compared with standard DDR3, but the platform must support low-voltage operation to benefit. Systems that only accept 1.5V DDR3 may not post or may run the module at higher voltage.

Replaces non-ECC or lower-capacity DDR3

Upgrading from non-ECC memory adds single-bit error correction for data integrity in critical workloads. Moving from 2GB or smaller modules increases total capacity without occupying additional slots. The jump is worth it when the motherboard supports ECC UDIMM and DDR3L voltage, and when the application demands both reliability and extra headroom.
