4GB DDR3L 1600 ECC RDIMM Server Module

This 4GB DDR3L 1600 ECC registered DIMM is built for server and workstation platforms that require error-correcting memory. The single-rank 1Rx8 module operates at 1.35V low voltage and uses major-brand chips to deliver dependable registered performance in 240-pin slots.

Verify DDR3L 1.35V Registered DIMM Support

Before ordering confirm that your system accepts DDR3L registered ECC memory at 1.35V and provides 240-pin DIMM slots. Many consumer boards only support unbuffered non-ECC modules so the registered design will not function there. Check the vendor memory-qualified list for 1600MHz CL11 compatibility.

Replaces Micron MT9KSF51272PZ-1G6 Equivalent

This module is a direct equivalent for the Micron MT9KSF51272PZ-1G6 part number. The upgrade is worthwhile when your server requires registered ECC memory at DDR3L voltage and you need to populate available slots with validated 4GB capacity. It is not suitable for systems that demand unbuffered or higher-density modules.
