Server-grade DDR4 kit

This 32 GB kit contains two 16 GB registered DIMMs built for servers that require DDR4 2933 operation. The modules carry ECC and a 2Rx8 organisation to protect data integrity in multi-socket or virtualised workloads. They are not suitable for standard desktop or laptop platforms.

Registered ECC integration

Each stick presents a 288-pin DDR4 interface and runs at 1.2 V, drawing power from the server’s memory controller without adding unbuffered signal load. The registered design reduces electrical stress on the memory bus, freeing the platform to populate more slots per channel. Systems without registered-DIMM support cannot use this memory.

Sustained 2933 throughput

Rated at PC4-23400 with CAS 21 latency, the modules maintain their rated transfer rate during extended compute or database tasks rather than throttling after short bursts. The dual-rank layout helps keep bandwidth stable across all populated channels under continuous load. Platforms limited to lower DDR4 speeds will clock the kit down automatically.

Questions about this item

Does the 2Rx8 dual-rank layout limit how many modules I can install per channel at full 2933 MHz?

Each 16 GB module uses a 2Rx8 organisation. Most server platforms cap dual-rank DIMMs to one per channel when running at the rated 2933 MT/s.

What thermal or power headroom should I plan for when the kit runs continuously at 1.2 V?

The modules operate at the standard DDR4 1.2 V with no extra voltage headroom required. Registered buffering adds negligible power draw, so typical server airflow is sufficient.

Must my motherboard have registered ECC RDIMM slots to use this kit?

Yes. The 288-pin RDIMMs need a server-class board that supports registered ECC DDR4. Consumer desktop boards will not accept them.
