512GB DDR4 2933MHz ECC Registered RDIMM kit

This kit provides 512GB of DDR4 2933MHz ECC registered memory across eight 64GB modules. It is built for servers, workstations and NAS systems that require registered DIMMs with error correction. Standard desktop platforms cannot use this memory and it must not be mixed with unbuffered modules.

Sustained throughput at 2933MHz with CL21 latency

Each module runs at 2933MHz with a CAS latency of 21 cycles and operates at 1.2V. The registered design adds a clock cycle of buffering to stabilise the command bus under heavy, continuous workloads. Backward compatibility allows operation at 2133MHz, 2400MHz or 2666MHz when the platform requires a lower speed.

Passive modules draw 1.2V with no onboard cooling

The 288-pin RDIMMs have no heat spreader and rely on system airflow for thermal management. At the rated 1.2V the modules run cool and silent, making them suitable for densely populated server chassis where fan noise and power draw must stay low.

Klausimai apie šią prekę

How much power do the 1.2V DDR4 2933MHz modules draw when the server runs continuously?

Each 64GB RDIMM operates at 1.2V, the standard DDR4 voltage, so total power scales with the eight modules installed and the platform's memory controller efficiency.

What must the system already support for this 8×64GB ECC registered kit to function?

The motherboard needs 288-pin DDR4 slots that accept ECC registered RDIMMs, a CPU and chipset qualified for 2Rx4 64GB density, and BIOS support for 512GB total capacity.

Will these CL21 2933MHz sticks run stably alongside existing 2133MHz or 2400MHz DDR4 ECC RDIMMs?

The modules are backward compatible with 2133MHz, 2400MHz and 2666MHz speeds; the system will clock all populated slots to the lowest common frequency and matching timings.
