32 GB ECC UDIMM kit for workstations

This OWC kit supplies 32 GB of DDR5 memory in two 16 GB modules. It is built for workstations, servers and NAS systems that require error-correcting code protection. The modules are unbuffered and run at the standard 1.1 V JEDEC voltage. No heat spreaders or LEDs are fitted.

Capacity and headroom at 4800 MT/s

Two 16 GB DIMMs give 32 GB total in a dual-channel configuration. The CL40 latency at 4800 MT/s handles typical workstation workloads and multi-tasking. Capacity runs out when applications demand more than 32 GB or when higher frequencies are required for specialised compute tasks. The kit stays within JEDEC limits for broad compatibility.

ECC unbuffered decides fit

The decisive specification is ECC unbuffered operation on a 288-pin DDR5 DIMM. Only platforms that support ECC unbuffered memory can use this kit; registered or non-ECC systems will not accept it. Verify the motherboard or server manual for ECC unbuffered support before purchase.

Soalan tentang produk ini

Will the 4800 CL40 DDR5 ECC UDIMM modules run alongside my existing DDR5 memory?

The kit uses JEDEC-standard DDR5 at 4800 MT/s and 1.1 V. Mixing with other DDR5 modules will work only if the other modules also run at 4800 MT/s and 1.1 V; otherwise the system will downclock all modules to the lowest common speed and voltage.

How can I confirm the 32 GB dual-channel kit is operating at 4800 MT/s CL40 with ECC active?

Enter the firmware or use a tool such as CPU-Z or dmidecode; each 16 GB module should show 4800 MT/s, CL40-40-40 timing, 1.1 V and ECC type "Unbuffered" for a total of 32 GB in dual-channel mode.

What does the 2 x 16 GB kit include and what must I supply?

The box contains two black 288-pin DDR5 ECC unbuffered UDIMMs (1Rx8, no heat spreaders). You must provide a compatible DDR5 motherboard or workstation with two free UDIMM slots and a CPU that supports ECC memory.
