Supermicro Certified 16GB DDR4 RDIMM

This A-Tech module is Supermicro certified and built with Hynix chips for validated compatibility. It delivers 16GB of DDR4 2666MHz ECC registered memory in a single 288-pin DIMM. The CL19 latency and 1.20V operation match standard server specifications.

For servers needing registered ECC memory

This module suits administrators upgrading or repairing Supermicro platforms that require RDIMM ECC modules. Builders assembling desktop PCs or workstations using unbuffered UDIMM slots should look elsewhere because this stick is registered and will not function in consumer motherboards.

Single rank 1Rx4 organisation

The 1Rx4 rank configuration determines how the memory controller addresses the chips and affects maximum population rules for specific Supermicro boards. Verify the platform's qualified vendor list to confirm this rank is supported in your target configuration.

Questions about this item

Does the 1.20V voltage limit thermal headroom when the module runs continuously in a fully populated server?

The module operates at the standard DDR4 1.20V, so power draw stays within JEDEC limits; sustained loads in a dense chassis will not push voltage beyond spec.

How much heat and noise does the 2666MHz registered DIMM add during all-day operation?

As a passive 288-pin RDIMM it produces no fan noise; heat output is low at 1.2V and is managed by the server’s existing airflow.

What motherboard slot and chipset support are required for this 1Rx4 ECC RDIMM to function?

A DDR4 288-pin RDIMM slot with ECC registered support is needed; the module is Supermicro certified for compatible platforms.
