OWC 32 GB DDR4 ECC Registered RDIMM

This 32 GB DDR4 3200 MHz PC4-25600 ECC Registered RDIMM is built for servers and workstations that require error-correcting registered memory. It will not work in standard desktop computers and cannot be mixed with unbuffered modules. The 288-pin 2Rx4 module matches Dell part numbers 370-AEVN, 75X1V, AA783422 and AA799087.

Thermals, noise and power draw

Operating at 1.2 V, the module draws minimal power and runs without a heat spreader, so it adds negligible heat to a server chassis. Passive cooling from system airflow is sufficient; there are no fans or moving parts to generate noise. The low voltage helps keep overall power consumption down in dense memory configurations.

Compliance and upgrade confidence

The memory is 100 % compliant with JEDEC specifications and ROHS compliant, providing a warranty-safe upgrade path. OWC tests every module in-house and backs it with a limited lifetime warranty and free technical support. Using identical capacity, speed and manufacturer across all DIMM slots ensures optimal performance.

Questions about this item

How do I install this 288-pin DDR4 RDIMM 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, then verify the server BIOS recognises the full 32GB capacity at 3200MHz.

What maintenance or replacement will this ECC registered module need over time?

No routine maintenance is required; if a correctable error count rises or the module fails, replace it with an identical 32GB 2Rx4 CL22 1.2V RDIMM to keep rank and timing matched.

What limit appears first when this RDIMM runs under sustained load?

The CL22 latency at 3200MHz sets the timing boundary; sustained throughput is capped by the JEDEC PC4-25600 data rate and the registered buffer's command cycle.
