32GB DDR4 ECC SODIMM for servers

This 32GB DDR4 3200 ECC SODIMM module is built for server and workstation systems that require error-correcting memory. It operates at CL22 latency with a standard 1.20V voltage and uses a 260-pin SO-DIMM form factor. The unbuffered design suits platforms that accept ECC unbuffered memory.

Thermals noise and power in normal use

Running at the standard 1.20V DDR4 voltage keeps power draw low during typical workloads. The module produces minimal heat under normal server or workstation operation. Passive cooling from system airflow is sufficient as no active cooling components are present on the module.

Build fit and system impact

The 260-pin SO-DIMM form factor fits compatible laptop, server, or workstation slots supporting DDR4 3200 ECC unbuffered memory. It replaces the Samsung M474A4G43AB1-CWE module directly. Verify your platform supports 32GB ECC unbuffered SODIMMs before installation as some systems limit capacity or ECC functionality.

Questions about this item

How do I install this 260-pin DDR4 SODIMM and what step is often missed?

Align the notch on the module with the slot key, press firmly until both side clips click, then verify in BIOS that the system reports 32 GB at 3200 MHz with ECC active.

What maintenance or replacement will this ECC SODIMM need over time?

No scheduled maintenance is required; keep the laptop vents clean so the 1.2 V module stays cool, and replace only if memory diagnostics report correctable errors rising above threshold.

What limit appears first when this CL22 module runs sustained workloads?

The CAS latency of 22 cycles at 3200 MHz sets the response-time floor, so latency-sensitive tasks hit that timing boundary before bandwidth saturates.
