32GB DDR4 2933MHz ECC RDIMM for Supermicro Servers

This 32GB registered DIMM runs at 2933MHz with CL21 latency and 1.20V operation. It uses Samsung chips in a 2Rx4 layout and carries Supermicro certification for compatible platforms. The module targets administrators who need validated ECC memory for stable server deployments.

Fits 288-pin DDR4 RDIMM slots on qualified

Registered buffering reduces electrical load on the memory controller, allowing higher capacities per channel. ECC circuitry corrects single-bit errors to protect data integrity in continuous workloads. Verify the system qualified-vendor list before installation to confirm support.

Maintains rated 2933MHz throughput under sustained

Samsung DRAM and registered signalling preserve timing margins during extended compute tasks. ECC correction operates transparently without halting the pipeline. The 1.20V standard voltage keeps thermals predictable in densely populated chassis.

Questions about this item

Does the CL21 latency limit sustained throughput on this 2933 MHz module?

CL21 is the rated CAS latency for this DDR4 2933 MHz RDIMM; it sets the timing baseline under sustained load.

How much heat or power does a 1.20 V 32 GB RDIMM produce when running all day?

At 1.20 V standard DDR4 voltage this 32 GB registered module operates within normal server thermal envelopes.

What motherboard slot and memory type must I already have for this 288‑pin DDR4 RDIMM?

A DDR4 RDIMM slot supporting 288‑pin registered ECC modules is required for installation.
