4GB DDR3L ECC SODIMM for servers

This 4GB DDR3L 1600 ECC SODIMM module targets administrators upgrading or repairing server and workstation laptops that require 204-pin low-voltage memory with error correction. It replaces Hynix HMT451A7AFR8A-PB and HMT451A7BFR8A-PB parts and is tested for compatibility with AMD and Intel platforms. The unbuffered design fits standard SO-DIMM slots without registered timing constraints.

Low-voltage operation keeps thermals modest

Running at 1.35V reduces power draw and heat output compared to standard 1.5V DDR3 modules, helping enclosed server chassis stay cooler under sustained workloads. CL11 latency at 1600MHz delivers stable throughput without aggressive timing that could increase voltage stress. The module operates silently with no active cooling required.

Fits 204-pin SO-DIMM slots in DDR3L systems

Installation requires a laptop or compact server board that accepts DDR3L 1.35V ECC unbuffered memory and provides a 204-pin SO-DIMM socket. The single-rank 1Rx8 organisation leaves additional slots free for further capacity expansion where the platform supports it. Verify your system's qualified vendor list before purchase to confirm supported densities and maximum total memory.

Questions about this item

How do I install the 204-Pin DDR3L SODIMM and which step is often missed?

Align the notch on the module with the slot key, press firmly until the side clips click, then verify the system detects 4GB at 1600 MHz in BIOS.

Will the ECC unbuffered module need any firmware updates or component swaps over time?

No firmware or component changes are required; the module is tested for lifetime reliability at 1.35V and CL11 latency.

What thermal or voltage limit appears first during sustained server workloads?

The 1.35V low-voltage specification is the primary operating limit; sustained loads stay within this envelope without throttling.
