32 GB DDR4 ECC Registered RDIMM

This 32 GB DDR4 2933 MHz module is built for servers, workstations and NAS systems that require ECC registered memory. It operates at 1.2 V with CL21 latency and a 2Rx4 rank configuration. The 288-pin RDIMM will not work in standard desktop computers or alongside unbuffered modules.

Thermals noise and power draw

Running at the JEDEC-standard 1.2 V keeps power draw low and heat output minimal without a heat spreader. Registered buffering reduces electrical load on the memory controller, helping stability in densely populated slots. No active cooling is required for normal server or workstation workloads.

Backward compatibility and compliance

The module is validated for backward compatibility with 2133, 2400 and 2666 MHz platforms, allowing mixed-speed deployments. Full JEDEC and RoHS compliance ensures a warranty-safe upgrade that meets OEM specifications. Each unit is tested in-house before shipment.

Questions sur cet article

How do I install this 288-pin DDR4 RDIMM and what step is often missed?

Align the notch with the slot key, press firmly until both retention clips click, then verify the system detects 32 GB at 2933 MHz in BIOS.

What maintenance or replacement will this 32 GB ECC registered module need later?

No routine maintenance is required; replace only if memory diagnostics report uncorrectable errors or the module fails POST.

What limit appears first when this CL21 1.2 V RDIMM runs under sustained load?

The CAS latency of CL21 at 2933 MHz sets the timing boundary before thermal or voltage limits are reached.
