128GB DDR4 ECC Registered Server Memory

This 128GB DDR4 3200 ECC Registered RDIMM is built for workstations and servers that require error-correcting, registered memory. It operates at PC4-25600 speed with CL22 latency and a 1.2V supply. The module uses a 288-pin 4Rx4 organisation and carries no heat spreader. It is not compatible with standard desktop computers or unbuffered memory configurations.

Thermals Noise and Power Draw

Running at the JEDEC-standard 1.2V, the module draws minimal power and generates low heat without a dedicated spreader. Passive cooling relies on chassis airflow, so a well-ventilated server enclosure keeps temperatures stable. No active cooling components are present, resulting in silent operation under normal workloads.

Bundled Accessories and Software Impact

The package contains only the memory module itself; no cables, brackets, or software utilities are included. Installation is a straightforward DIMM insertion that immediately adds 128GB of ECC-protected capacity. OWC's advanced replacement programme and limited lifetime warranty provide long-term support without altering system behaviour.

Questions sur cet article

How do I install the 288-Pin DDR4 RDIMM in a Supermicro server, and what step do people often skip?

Align the notch on the 288-Pin module with the slot key, press firmly until both side clips click, and verify the server BIOS recognises the full 128GB at 3200MHz; the step often skipped is confirming the memory mode is set to registered ECC in the firmware.

What maintenance or replacement will the 128GB 4Rx4 module need over its service life?

The module has no moving parts or heat spreader, so no scheduled maintenance is required; replacement is only needed if a memory test reports correctable ECC errors that exceed the platform threshold.

What limit appears first when the 1.2V CL22 RDIMM runs sustained workloads?

The 1.2V operating voltage and CL22 latency define the thermal and timing envelope; under continuous load the memory controller’s thermal throttle point is reached before the module’s own rating.
