ECC SODIMM for microservers and workstations

This 4 GB DDR4 module adds error-correcting memory to compatible microservers, mobile workstations and NAS servers. It runs at 2400 MHz with a CL17 latency and standard 1.2 V operation. The single-rank 1Rx8 layout fits 260-pin SO-DIMM slots that specifically support unbuffered ECC.

Cooling and power in daily operation

Without a heat spreader the module relies on system airflow, which is typical for SODIMM form factors. At 1.20 V the power draw stays within standard DDR4 limits for laptop-class hardware. No active cooling or additional voltage is required.

The specification that decides fit

Your platform must support DDR4 ECC unbuffered SO-DIMM memory; standard non-ECC laptop slots will not accept this module. Verify the motherboard or system manual for ECC SODIMM compatibility before purchase.

Questions about this item

How do I install this 260-pin DDR4 SODIMM and what step do people often miss?

Align the notch on the module with the slot key, press firmly until the side clips click into place, and verify the system recognises the full 4GB capacity in BIOS.

Will this ECC unbuffered module need any maintenance or replacement over time?

No routine maintenance is required; the module has no heat spreader and uses standard 1.20V DDR4 voltage, so it runs passively for its service life.

What limit appears first when this CL17 2400 MHz module runs under sustained load?

The CAS latency of 17 cycles at 2400 MHz sets the timing floor, so latency-bound workloads hit that ceiling before bandwidth saturates.
