32GB DDR4 ECC Registered RDIMM

This 32GB DDR4 module runs at 2400MHz with CL17 latency and 1.2V operation. It is built as a 2Rx4 registered DIMM with ECC for data integrity in server and workstation platforms. The 288-pin form factor fits standard DDR4 RDIMM slots.

JEDEC compliant registered design

The module follows JEDEC specifications and is RoHS compliant. It uses a registered buffer to reduce electrical load on the memory controller, allowing higher capacities per channel. No heat spreader is present, so airflow in the chassis manages thermals directly.

Upgrade for ECC registered systems

This part replaces or adds to existing DDR4 ECC registered memory in compatible servers, workstations or NAS units. It cannot be used in standard desktop boards or mixed with unbuffered modules. Buyers who need non-ECC or unbuffered memory should select a different product.

Questions about this item

Does the DDR4-2400 PC4-19200 rating limit real-world bandwidth to 19200 MB/s?

The PC4-19200 designation marks a peak transfer rate of 19200 MB/s; actual sustained throughput depends on the server's memory controller and channel population.

Will this 288-pin registered DIMM fit in a standard desktop motherboard?

No, the 288-pin RDIMM keying and registered buffer require a server or workstation board that supports ECC registered memory; standard desktop boards accept only unbuffered UDIMMs.

What is the correct installation sequence for this 2Rx4 ECC registered module?

Power down the system, open the chassis, align the module notch with the slot key, press firmly until both retention clips click, then verify in BIOS that the module reports 32GB at 2400 MHz with ECC active.
