32 GB DDR3 1866 ECC Kit

This OWC kit supplies 32 GB of DDR3 1866 memory across eight 4 GB unbuffered UDIMMs. Each module runs at 1.5 V with CL13 latency and includes error-correcting code for data integrity. The 240-pin DIMMs are built to JEDEC and RoHS standards for broad workstation and server compatibility.

Workstations and NAS needing ECC

The kit targets desktops, workstations and NAS systems that require ECC unbuffered DDR3. Systems without ECC support or those limited to registered memory will not benefit. Buyers using consumer platforms that lack ECC capability should choose non-ECC modules instead.

Straightforward DIMM installation

Install by powering down, opening the case and seating each 240-pin module until the retention clips click. Common issues include mixing ECC with non-ECC DIMMs, populating slots in the wrong channel order, or leaving a module partially inserted causing boot failure.

Soalan tentang produk ini

What motherboard slot type is required for these 240-pin DDR3 ECC UDIMMs?

The modules use a standard 240-pin DDR3 UDIMM form factor, so the board must provide DDR3 DIMM slots that accept unbuffered ECC memory.

Can I mix these CL13 1866 MHz sticks with slower DDR3 modules already installed?

The kit runs at DDR3 1866 CL13 1.5 V; the system will downclock all modules to the slowest installed speed and loosest timings.

How do I confirm the full 32 GB kit is recognised with ECC active after installation?

Check the BIOS memory summary for 32 GB total and ECC enabled, then verify in the operating system with a tool that reports ECC status.
