4GB DDR3 ECC UDIMM for workstations

This OWC module adds 4GB of DDR3 1600 memory with ECC error correction. It runs at 1.5V with CL11 latency in the standard 240-pin UDIMM form factor. The unbuffered design suits desktop workstations, servers and NAS units that require data integrity without registered memory.

Upgrade from non-ECC or lower-capacity DDR3

Replacing standard non-ECC modules with this ECC version adds single-bit error correction for workloads that cannot tolerate silent data corruption. The jump is worth it when the platform supports ECC unbuffered memory and the application demands uptime over raw bandwidth. A single 4GB stick also fills a lone slot on boards limited to one DIMM per channel.

Fits 240-pin DDR3 slots at 1.5V

The module plugs directly into any DDR3 240-pin slot wired for 1.5V unbuffered ECC operation. No heat spreader means it clears tall CPU coolers and dense server chassis without extra clearance planning. It frees a second slot for a matching stick to run dual-channel when the board supports it.

Questions about this item

Will the 240-pin DDR3 DIMM fit my desktop motherboard?

The module uses the standard 240-pin DDR3 form factor and 1.5V operation, matching JEDEC specifications for compatible desktop, workstation and server boards.

What is the correct way to seat the 240-pin DDR3 module, and what step do people often miss?

Align the notch with the slot key, press firmly until both side clips click shut, then verify the system recognises the full 4GB at 1600 MHz CL11 in BIOS.

When should I consider replacing this ECC UDIMM?

Replace it if memory diagnostics report correctable or uncorrectable ECC errors, if the system fails to POST with the module installed, or if you need capacity beyond 4GB.
