A-Tech 4GB DDR3L 1333 ECC UDIMM 2Rx8 1.35V Micron MT18KSF51272AZ-1G4 Server Memory

4 GB DDR3L ECC UDIMM for servers

This 4 GB DDR3L ECC UDIMM module operates at 1333 MHz with CL9 latency and runs at 1.35 V. It uses a 2Rx8 organisation with major-brand chips on a 240-pin DIMM. The stick is built as a direct replacement for the Micron MT18KSF51272AZ-1G4 part and is intended for server or workstation systems that require error-correcting unbuffered memory.

Fits DDR3L 240-pin ECC UDIMM slots

The module plugs into any DDR3L 240-pin DIMM socket that accepts unbuffered ECC memory at 1333 MHz. Because it is unbuffered it does not need a registered memory controller, freeing a registered DIMM slot for other configurations. The low 1.35 V voltage reduces power draw compared with standard DDR3, leaving more headroom for other components in the chassis.

Tested replacement with lifetime warranty

Each unit undergoes quality-assurance testing before shipment to verify reliable operation in the target platform. The module is validated as a compatible equivalent for the Micron MT18KSF51272AZ-1G4, simplifying procurement for maintenance or upgrades. A lifetime warranty and US-based technical support are included with the purchase.
