Server ECC Registered RDIMM

This OWC module is an 8GB DDR3 1866 PC3-14900 CL13 1Rx4 240-pin 1.5V ECC Registered RDIMM built for select workstations and servers. It uses registered buffering and error-correcting code to maintain data integrity in multi-module configurations. The single-rank x4 organisation fits systems that require registered DIMMs. It is not compatible with standard desktop computers or unbuffered memory.

Installation notes

The 240-pin DIMM seats in a standard DDR3 RDIMM slot with the key notch aligned; no heat spreader is present so clearance is minimal. Systems must support registered ECC memory at 1.5V and the PC3-14900 speed grade; mixing with unbuffered modules will prevent boot. Firmware should be current before adding capacity. Handle the module by the edges to avoid static damage.

Compatibility checklist

Verify that your motherboard or chassis accepts DDR3 ECC Registered RDIMMs and lists PC3-14900 1866MHz CL13 at 1.5V in its qualified vendor list. Confirm the maximum supported capacity per slot and total population rules for registered modules. Ensure the platform does not require load-reduced or unbuffered DIMMs instead. Cross-reference the part number 1R8D31R408GB with the vendor documentation.

Preguntas sobre este artículo

How can I confirm the 8GB DDR3 1866 CL13 module is running at the correct speed after installation?

Enter the system BIOS or UEFI and verify the memory frequency reads 1866 MHz with CAS latency CL13 and 1.5 V.

What comes in the package and are any extra parts required for a server install?

The box contains one 8 GB 240-pin DDR3 ECC Registered RDIMM; no additional components are needed if your workstation or server has a free DDR3 RDIMM slot.

Should I choose the 1Rx4 8 GB version or a different capacity for my upgrade?

Select this 1Rx4 8 GB module when your platform requires a single-rank registered DIMM at 1866 MHz; match the rank and voltage to your system's memory configuration.
