Server ECC RDIMM 16GB

This 16GB DDR4 2933 PC4-23400 ECC RDIMM module is built for SuperMicro server and workstation platforms. Registered buffering and error-correcting code protect data integrity in mission-critical workloads. It installs in a standard 288-pin DDR4 slot at 1.20V. The single-rank 1Rx8 organisation keeps electrical loading low for dense configurations.

Suited for registered memory slots only

Systems that require unbuffered UDIMM or non-ECC modules cannot use this part. Laptops and consumer desktops with 260-pin SO-DIMM or standard UDIMM slots are incompatible. Builders needing higher density per slot or different CAS latency values should evaluate other modules.

Registered ECC with CL21 latency

The module operates at CL21 CAS latency with registered buffering. This combination determines whether the memory controller can train the link at 2933 MT/s. Verify the platform qualified vendor list for this exact part number before purchase.

Questions about this item

Does the 1.20V registered DDR4 module add noticeable heat or fan noise when the server runs all day?

The module runs at 1.20V with no heat spreader, so thermal load is minimal and it does not introduce extra fan noise in a properly cooled chassis.

What must the system already provide for this 288-pin ECC RDIMM to function?

A Supermicro motherboard with DDR4 RDIMM slots that support 2933 MT/s registered ECC memory and a BIOS configured for ECC operation.

How does this CL21 2933 module behave alongside slower DDR4 RDIMMs the buyer may keep?

The memory controller will down-clock all installed RDIMMs to the lowest common speed and highest latency, so older modules set the pace for the whole channel.
