OWC 32GB DDR5 ECC UDIMM Kit

This OWC kit provides 32GB of DDR5 memory in a matched pair of 16GB unbuffered UDIMMs. Each module runs at 5200 MT/s with a CL42 latency at the JEDEC standard 1.1V. Error-correcting code is built in for data integrity. The modules use a plain black PCB without a heat spreader or lighting.

Suited For ECC Workstations And NAS

The kit targets workstations, servers and NAS systems that require ECC unbuffered DDR5 memory in a dual-channel configuration. Systems that need registered or load-reduced DIMMs cannot use these modules. Builds without ECC support in the memory controller will not benefit from the error-correction feature.

288-Pin DDR5 ECC Unbuffered Form Factor

The decisive specification is the 288-pin DDR5 ECC unbuffered UDIMM form factor combined with 5200 MT/s JEDEC speed. Only motherboards and platforms that explicitly support DDR5 ECC unbuffered memory at this pin count and voltage can accept the kit.

Questions about this item

Will the 288-pin DDR5 modules need any replacement or maintenance after installation?

No, DDR5 ECC UDIMMs are solid-state components with no moving parts and require no scheduled maintenance or replacement under normal use.

What limit appears first when the kit runs at 5200 MT/s CL42 continuously?

The JEDEC-standard 1.1 V operating voltage and CL42 latency define the sustained performance envelope; thermal throttling is unlikely without a heat spreader.

How much noise, heat or power draw should I expect from the 32 GB kit during all-day operation?

The modules draw 1.1 V with no active cooling, so they produce minimal heat, zero audible noise and low power consumption even under constant load.
