OWC 16GB DDR4 2400MHz ECC UDIMM

This 16GB DDR4 module runs at 2400MHz with CL17 latency and ECC error correction. It is an unbuffered 288-pin DIMM operating at 1.2V, designed for workstations, servers and NAS systems. The single 2Rx8 rank stick meets JEDEC standards and requires no heat spreader.

Upgrade from non-ECC or slower DDR4

The module replaces standard non-ECC memory or slower DDR4 2133MHz sticks, adding data integrity for critical workloads. The jump is worth it when your platform supports ECC unbuffered DIMMs and you need protection against silent data corruption in professional or server environments.

16GB capacity for moderate workloads

Sixteen gigabytes handles typical workstation multitasking, virtual machines and mid-sized datasets comfortably. Headroom runs out with large in-memory databases, heavy rendering queues or many concurrent VMs, at which point adding further identical modules or moving to higher-capacity sticks becomes necessary.

Questions about this item

Will the 288-pin DDR4 module fit my desktop motherboard?

The module uses the standard 288-pin DDR4 UDIMM form factor and requires a desktop motherboard with DDR4 DIMM slots that support ECC unbuffered memory.

What is the correct way to seat the 16GB stick so the system recognises the full capacity?

Align the notch on the module with the slot key, press down firmly until both side clips click into place, and verify the BIOS reports 16GB at 2400MHz CL17.

Does the ECC unbuffered design need any periodic maintenance or firmware updates?

No scheduled maintenance is required; the module has no heat spreader or LEDs, and ECC error correction operates automatically without user intervention.
