32 GB dual-channel ECC kit

This OWC kit supplies 32 GB of DDR4 memory in a matched pair of 16 GB unbuffered UDIMMs. Error-correcting code protects data integrity for workstations, servers and NAS devices. The modules run at 2400 MHz with CL17 latency at 1.2 V.

JEDEC compliance and backward compatibility

Each module meets JEDEC PC4-19200 specifications and is RoHS compliant. The kit also operates at 2133 MHz when installed in systems limited to that speed. No heat spreader is fitted, keeping the profile low for dense server chassis.

288-pin unbuffered DIMM form factor

The standard 288-pin layout fits desktop, workstation, server and NAS motherboards that accept unbuffered ECC UDIMMs. Black PCBs give a neutral appearance. Installation follows typical DIY memory upgrade procedures.

Questions about this item

Will this memory fit a standard desktop motherboard with 288-pin DDR4 slots?

Yes, the kit uses the standard 288-pin DDR4 UDIMM form factor and runs at 1.2 V, so it installs in any desktop board that accepts unbuffered DDR4 DIMMs.

Does my system need to support ECC for these modules to work?

The modules include ECC circuitry, but they will operate as non-ECC memory on consumer platforms that do not enable ECC; full error correction requires a CPU and chipset that support it.

Can I mix this 2400 MHz kit with existing 2133 MHz DDR4 memory?

The kit is backward compatible with 2133 MHz DDR4, so it will downclock automatically to match slower modules already installed.
