8 GB DDR4 ECC SODIMM for Samsung systems

This 8 GB DDR4 2666 ECC SODIMM is built for Samsung servers, workstations and NAS units that require unbuffered error-correcting memory. The single-rank 1Rx8 module runs at 1.2 V with CL19 latency and fits 260-pin SO-DIMM slots.

Sustained load behaviour with ECC active

Error-correcting code operates continuously during long compute or storage tasks, detecting and correcting single-bit errors without halting the system. Unbuffered design keeps latency low while the Samsung-sourced DRAM chips maintain stability across extended workloads.

Verify slot count and ECC support before ordering

Confirm the target machine accepts 260-pin DDR4 SODIMMs and enables ECC in the BIOS or firmware. Systems limited to non-ECC memory or soldered RAM cannot use this module, and maximum capacity per slot may restrict total upgrade size.

Questions about this item

How much heat does the 1.20V 260-PIN SODIMM produce when running continuously?

The module operates at 1.20V without a heat spreader, so it relies on system airflow to stay cool during extended use.

What must the host system provide for this ECC SODIMM to function?

The laptop or NAS needs a DDR4 SODIMM slot that accepts 260-PIN unbuffered ECC memory at 1.20V and supports CL19 timing.

Will the 1Rx8 8GB module work in a Samsung system that currently uses a 1Rx8 4GB stick?

Yes, both are 1Rx8 unbuffered ECC SODIMMs at the same voltage and pin count, so they can populate separate slots on a compatible Samsung platform.
