4GB DDR3L ECC UDIMM for servers

This 4GB DDR3L module runs at 1333 MHz with CL9 latency and 1.35V operation. It is an unbuffered ECC UDIMM built with 2Rx8 organisation on a 240-pin DIMM. The stick targets administrators upgrading or repairing compatible server and workstation platforms.

Capacity and headroom

Four gigabytes adds modest capacity for light virtualization, file serving or legacy application workloads. The single rank layout leaves additional DIMM slots free for further expansion where the platform allows. Workloads needing large in-memory datasets or heavy multi-tenant consolidation will exceed this module alone.

240-pin DDR3L 1.35V interface

The 240-pin DDR3L interface at 1.35V is the decisive compatibility factor; systems requiring 1.5V DDR3 or registered DIMMs cannot use this module. Verify the motherboard qualification list for the exact Samsung M391B5273CH0-YH9 or M391B5273DH0-YH9 part numbers before purchase.
