Server ECC RDIMM Kit

This OWC kit provides 32GB of DDR5 memory in a matched pair of 16GB modules. It is built for workstations and servers that require registered ECC DDR5 DIMMs. Standard desktop computers cannot use this memory type.

JEDEC Compliant Dual Channel

The two modules are tested together for dual-channel operation at 4800 MT/s with CL40 latency. JEDEC standard voltage of 1.1V and ROHS compliance ensure a warranty-safe upgrade without manual tuning. No heat spreaders are included.

Registered 1Rx4 Architecture

The 1Rx4 registered design with on-die ECC is the single specification that determines compatibility. This memory will not work in systems that require unbuffered or load-reduced DIMMs. Mixing with other module types is not supported.

商品問答

Will the CL40 latency require any future adjustment or replacement?

CL40 is the factory-set CAS latency for these DDR5 modules and does not change over time; no maintenance or replacement is needed for the latency setting itself.

What limit appears first when the 4800 MT/s kit runs continuously?

Sustained operation is constrained by the 1.1 V JEDEC voltage and the registered ECC design, which together define the thermal and stability ceiling before any throttling would occur.

How much heat or noise do the 1Rx4 registered DIMMs produce under all-day load?

The modules have no heat spreader and no moving parts, so they add only the normal DDR5 power draw at 1.1 V and generate no audible noise during continuous use.
