16GB DDR4 ECC SODIMM for servers and workstations

This module adds 16GB of DDR4 error-correcting memory to laptops, microservers or NAS units that accept unbuffered ECC SO-DIMMs. It targets administrators and power users who need data integrity for always-on workloads. The single stick leaves other slots free for future expansion. Systems without ECC support in the chipset or BIOS cannot use this module.

Capacity and headroom at 2133 MHz

The 16GB dual-rank stick handles virtualisation hosts, ZFS caches and multi-VM labs with comfortable headroom for concurrent services. Workloads that exceed 16GB of active pages will swap to storage, increasing latency. The CL15 timing and 2133 MHz bus deliver standard JEDEC throughput; heavier compute tasks may benefit from higher-frequency modules if the platform allows them.

ECC unbuffered requirement decides fit

The defining specification is ECC unbuffered operation on a 260-pin DDR4 SO-DIMM interface. Only platforms that explicitly support ECC SO-DIMMs will initialise the module and enable error correction. Buyers must confirm their motherboard or laptop documentation lists ECC unbuffered SO-DIMM support before purchase.

Questions about this item

Will this 260-pin DDR4 2133 MHz ECC SODIMM work in an older laptop that only supports non-ECC DDR4 2133?

The module is ECC unbuffered; it requires a system that explicitly supports ECC SODIMMs. A laptop limited to non-ECC DDR4 will not recognise or use the error-correction function and may not boot.

How can I confirm the 16 GB module is running at CL15 1.20 V after installation?

Open the BIOS or a system-information tool such as CPU-Z and verify the reported speed shows 2133 MHz, CAS latency 15, voltage 1.20 V and that ECC is listed as active.

Does the single 16 GB stick ship with any heat spreader or extra cables?

The module has no heat spreader and includes only the SODIMM itself; no cables, brackets or additional accessories are supplied.
