OWC 32GB DDR4 2400MHz ECC RDIMM

This 32GB registered DDR4 module operates at 2400MHz with CL17 latency and 1.2V power. It is built for Supermicro X10DRT series motherboards including the B+, P, PIBF, PIBQ and PT models. The part replaces multiple Supermicro MEM-DR432 part numbers.

Passive thermals low power draw

Without a heat spreader the module relies on chassis airflow and runs at the standard 1.2V DDR4 voltage. Registered buffering and ECC add minimal overhead while keeping signal integrity high. Power draw stays within JEDEC limits for PC4-19200 operation.

Registered ECC not for desktops

This RDIMM requires a platform that supports registered ECC memory and will not work in standard desktop computers. It also cannot be mixed with unbuffered DIMMs in the same system. Buyers needing non-ECC or unbuffered memory should look elsewhere.

Questions about this item

How do I install the OWC 32GB DDR4 2400MHz RDIMM into my Supermicro X10DRT motherboard, and what step is often missed?

Align the notch on the 288-pin module with the slot key, press firmly until both retention clips click, and verify the system detects the full 32GB capacity at 2400MHz CL17 in BIOS.

What maintenance or replacement will this ECC Registered DIMM need over time?

No routine maintenance is required; the module has no heat spreader, so keep server airflow clean, and replace only if memory diagnostics report correctable errors exceeding thresholds.

What limit appears first when this 1.2V 2Rx4 module runs sustained workloads?

The registered buffer and CL17 latency cap throughput at DDR4 2400 PC4-19200; sustained use stays within JEDEC 1.2V spec without thermal throttling.
