Server ECC Registered DIMM

This OWC module provides 32GB of DDR4 2400 ECC Registered memory in a 288-pin VLP form factor. It is built for workstations and servers that require registered DIMMs with 2Rx4 organisation and 1.2V operation. The part is not compatible with standard desktop computers or with unbuffered and load-reduced memory types.

JEDEC and RoHS compliance

The module meets JEDEC standard specifications and RoHS requirements, making it a warranty-safe upgrade for supported OEM platforms. It is validated as a direct replacement for Samsung M392A4K40BM0-CRC, Hynix HMAA4GR8AMR4NUH and Micron MTA36ADS4G72PZ2G3 parts. Matching capacity, speed and manufacturer across all slots is recommended for optimal performance.

DIY installation notes

Installation follows the standard DIMM insertion procedure for the target server or workstation. The most common issue is attempting to use this registered ECC module in a consumer desktop board that only accepts unbuffered non-ECC memory. Mixing with unbuffered or load-reduced DIMMs will also prevent the system from posting.

Questions about this item

Does this module include a heat spreader or any cooling hardware?

The module is listed without a heat spreader, so it relies on chassis airflow across the bare DRAM packages.

What electrical or thermal limit appears first when this DIMM runs continuously at DDR4 2400?

Continuous operation at the rated 1.2 V and CL17 timing keeps the module within JEDEC DDR4 specifications; the first limit reached will be the platform memory-controller thermal envelope.

How much power does a single 32 GB stick draw under all-day load?

At the specified 1.2 V the module follows standard DDR4 2400 power envelopes; exact watts depend on the server memory controller workload.
