256 GB DDR4 2933 MHz ECC registered RDIMM kit in eight 32 GB modules at CL21 1.2 V, validated for the ASUS WS C621E SAGE workstation motherboard
This 256 GB kit contains eight 32 GB DDR4-2933 registered ECC RDIMMs built to the precise rank, voltage and timing the motherboard expects. The modules operate at 1.2 V with CL21 latency and use a 288-pin form factor so the board recognises the full capacity at rated speed without manual tuning.
Registered buffering offloads the memory controller, allowing every slot to run fully populated at 2933 MHz while ECC corrects single-bit errors on the fly. The kit requires a motherboard that accepts 288-pin DDR4 RDIMMs and follows the manufacturer's DIMM population rules; no heat spreaders are included, so airflow in the chassis must be adequate for sustained server workloads.
Builders expanding an ASUS WS C621E SAGE to its supported memory limit will find the spec-matched kit eliminates compatibility guesswork. Buyers who need unbuffered UDIMMs, SODIMMs, a different DDR generation, or smaller capacities should look at other memory lines that match those requirements.

Other versions of this model
At 1.2V the kit draws the standard DDR4 voltage, keeping power consumption and thermals in line with other registered ECC modules rated for 2933 MHz.
The memory controller on the C621E SAGE reaches its maximum supported capacity of 256GB, so no further DIMMs can be added without changing the platform.
A CPU and chipset that support registered ECC DDR4 at 2933 MHz, plus a BIOS configured for the correct population order across all eight slots.
