Server memory kit for data centres

This 512GB kit contains eight 64GB DDR4 2933MHz ECC RDIMM modules rated at CL21 and 1.2V. It is built for servers and workstations that require registered memory with error correction for mission-critical workloads.

Fits 288-pin DDR4 RDIMM slots only

Each module uses a 2Rx4 organisation and registered buffering, so the motherboard must support registered ECC DDR4 memory. The kit occupies eight slots and frees the installer from mixing different capacities or speeds.

Runs at standard 1.2V without heat spreaders

The modules operate at the JEDEC DDR4 voltage and have no integrated heat spreaders, relying on chassis airflow for cooling. Power draw scales with all eight modules populated, and noise depends entirely on the system fan configuration.

Questions about this item

Does the CL21 latency limit throughput when the kit runs at 2933 MHz all day?

CL21 is the rated timing at DDR4 2933; sustained throughput follows the PC4-23400 bandwidth ceiling.

How much heat do the eight 64 GB modules produce at 1.2 V under continuous load?

Registered DDR4 RDIMMs at 1.20 V run cool enough for standard server airflow; no heat spreaders are fitted.

Must the motherboard already support 2Rx4 registered ECC DIMMs for this 512 GB kit to work?

Yes — the platform needs DDR4 RDIMM slots that accept 2Rx4 registered ECC modules.
