128GB DDR5 ECC kit for workstations

This OWC kit delivers 128GB of DDR5 memory across four 32GB modules. It runs at 4800 MT/s with a CL40 latency and operates at 1.1V. The modules are unbuffered ECC UDIMMs built for select workstations, servers and NAS systems.

JEDEC-standard 288-pin unbuffered DIMMs

Each stick uses the standard 288-pin DDR5 form factor without a heat spreader. Unbuffered ECC circuitry provides error correction for data integrity in critical workloads. The black PCBs fit standard desktop DIMM slots and require no extra clearance for oversized coolers.

Verify DDR5 ECC UDIMM support before ordering

Confirm your platform accepts DDR5 unbuffered ECC UDIMMs at 4800 MT/s and 1.1V. Check that the motherboard or workstation manual lists support for 2Rx8 32GB modules and a four-module population. Ensure the BIOS is current for full compatibility.

Questions sur cet article

Will this kit run at 4800 MHz on a board that only supports 4800?

Yes, the modules are rated DDR5 4800 (PC5-38400) and will operate at that speed on any compatible motherboard.

Do I need a CPU and chipset that support ECC unbuffered memory?

Yes, ECC unbuffered DIMMs require a platform that explicitly enables ECC; standard consumer desktop chipsets usually do not.

Can I install the four 32 GB sticks in a dual-channel workstation?

The kit contains four 32 GB modules for 128 GB total; populate all four slots on a dual-channel board to run in dual-channel mode.
