32 GB DDR3-1866 ECC UDIMM kit

This OWC kit supplies 32 GB of DDR3 memory as four 8 GB unbuffered UDIMMs. Modules run at 1866 MT/s with CL13 latency and 1.5 V operation. ECC support adds error detection for data integrity in workstations, servers and NAS systems.

Suitability and alternatives

The kit suits desktop, workstation and server platforms that accept 240-pin DDR3 ECC unbuffered DIMMs. Systems requiring registered or load-reduced modules cannot use these sticks. Builders needing non-ECC memory or a different DDR generation should select another product.

Deciding specification

ECC unbuffered DDR3 at 1866 MT/s is the single specification that determines fit. Verify the motherboard or server documentation for 240-pin DDR3 ECC unbuffered support before purchase.

Questions about this item

Will this kit work in a system that requires unbuffered ECC DDR3 at 1866 MHz?

Yes. The modules are DDR3 1866 (PC3-14900) with CL13 timing, 1.5 V operation and unbuffered ECC, matching those exact requirements.

Does the 240-pin form factor fit standard desktop, workstation and server DIMM slots?

The 240-pin UDIMM design is the standard DDR3 desktop, workstation and server form factor, so it installs in any board that accepts unbuffered DDR3 DIMMs.

What does the 2Rx8 organization mean for my memory controller?

Each 8 GB module uses a dual-rank x8 layout, presenting two ranks per DIMM; ensure your platform supports that rank count per channel for full 32 GB operation.
