32GB DDR4-2933 ECC RDIMM

This 32 GB registered DDR4 module runs at 2933 MT/s with CL21 latency and 1.20 V operation. It is built for Supermicro servers and workstations that require ECC error correction and registered signalling. The single 2Rx8 rank fits one 288-pin slot. Buyers needing non-ECC or unbuffered memory for consumer boards cannot use this part.

Registered ECC with 2Rx8 organisation

The module uses registered ECC RDIMM architecture with a 2Rx8 rank layout, which is the single specification that determines compatibility with the target Supermicro platforms. Systems that accept only unbuffered UDIMMs or that require a different rank configuration will not post with this installed. No other memory type or rank arrangement is supported by this module.

Passive operation at 1.20 V

Without a heat spreader the DIMM relies on chassis airflow and its low 1.20 V supply to stay cool in normal server workloads. Power draw remains modest because the registered buffer and ECC logic operate at standard DDR4 voltage. Acoustic impact is zero since the module has no moving parts.

Questions about this item

What real-world throughput does the DDR4-2933 CL21 module provide once installed?

The module runs at DDR4-2933 with CL21 latency; actual throughput depends on the platform's memory controller and channel configuration.

How does the RDIMM registered interface affect usable speed and capacity?

The registered design adds one cycle of buffering for signal integrity, allowing higher capacities per channel while operating at the rated DDR4-2933 speed.

What slot and physical clearance does the 288-pin RDIMM need?

It requires a standard 288-pin DDR4 RDIMM slot and fits low-profile builds because it has no heat spreader.
