128GB DDR4-2933 ECC RDIMM

This 128GB registered DDR4 module runs at 2933MHz with CL21 latency and 1.20V operation. It uses a 4Rx4 quad-rank layout built on Samsung 3DS/TSV chips and carries Supermicro certification for validated server platforms.

Registered ECC limits and rank constraints

Registered ECC RDIMMs require a chipset and CPU that support registered signalling and error correction; consumer desktop boards will not POST with them. The 4Rx4 quad-rank organisation increases electrical load per slot, so the maximum number of modules per channel is often lower than with single or dual-rank DIMMs.

Verify platform qualification before ordering

Confirm that your motherboard or server qualified vendor list includes the MEM-DR412MH-ER29 part number and supports 128GB quad-rank RDIMMs at 2933MHz. Check the maximum supported capacity per slot and total system capacity, as some platforms cap registered DIMM density below 128GB. Ensure the BIOS revision in use recognises Samsung 3DS/TSV modules.

Preguntas sobre este artículo

Should I choose the 128GB quad-rank module or a lower-capacity alternative?

This module provides 128GB in a single 288-pin RDIMM using 3DS/TSV technology with a 2S2Rx4 (4Rx4) organisation. Select it when your server board supports quad-rank registered DIMMs and you need maximum density per slot.

What does the 2933 MHz speed rating deliver in an actual server?

The module runs at DDR4 2933 (PC4-23400) with CL21 latency at 1.20V, giving 23400 MB/s peak bandwidth per stick when the platform enables that data rate.

Is this DDR4 RDIMM limited by the registered ECC interface?

The registered ECC interface adds one clock cycle of buffering for signal integrity, allowing dense 4Rx4 loads on 288-pin DDR4 server boards while maintaining the 2933 MHz specification.
