Server memory upgrade

This single 128GB DDR4 3200 module is an ECC registered RDIMM built for ASRock OCP and bare-bone server platforms. It targets administrators who need to expand memory capacity in compatible workstations or NAS systems. The 288-pin form factor fits registered DIMM slots only.

Compatibility check

Verify that your motherboard accepts ECC registered DDR4 and does not require unbuffered or load-reduced modules. The listed ASRock OCP 1OU3N-MILAN/ORV3 and 4U server barebones are confirmed platforms; other boards must explicitly support registered ECC memory. Mixing with unbuffered or LR-DIMM modules will prevent operation.

Build and connectors

The module operates at 1.2V with CL22 latency and an 8Rx4 organisation. No heat spreader is fitted, so airflow across the DIMM rows must be maintained by the chassis. JEDEC and RoHS compliance ensures a warranty-safe upgrade. Backward compatibility with 2133, 2400, 2666 and 2933 speeds allows deployment in mixed-speed configurations.

商品問答

Does the 128GB DDR4 3200 RDIMM ship as a single stick or a kit, and are any brackets or cables required for installation?

The upgrade consists of one 128GB 288-pin DDR4 3200 ECC Registered RDIMM. No brackets, cables or additional parts are needed; it installs directly into a compatible DIMM slot.

How do I decide between this 128GB 8Rx4 module and a lower-capacity alternative for my ASRock OCP 1OU3N-MILAN/ORV3?

Choose the 128GB 8Rx4 module when you need maximum capacity per slot on supported ASRock OCP and 4U barebone servers; smaller capacities use fewer ranks and suit lighter workloads.

What does the 3200 PC4-25600 rating mean once the module is running in a server that only supports 2666 MT/s?

The module will down-clock to 2666 MT/s (or 2133, 2400, 2933 MT/s) while keeping CL22 timing and 1.2V operation, delivering full ECC Registered stability at the platform's top speed.
