ASUS WS C621E SAGE 192GB DDR4 ECC RDIMM kit

This 192GB kit contains six 32GB DDR4 2933MHz registered ECC RDIMMs built for the ASUS WS C621E SAGE workstation motherboard. Each module runs at 1.2V with CL21 latency and a 2Rx8 organisation. The registered design lets the memory controller address every slot at full population.

Upgrade from partial or slower memory configurations

Replacing a smaller set of modules or slower DIMMs with this matched 6x32GB kit restores full-channel bandwidth and eliminates mixed-rank instability. The jump is worth it when your workload needs the full 192GB capacity at the board's native 2933MHz speed without down-clocking.

Suits workstations running ECC-critical workloads

Builders who need registered ECC memory validated for the ASUS WS C621E SAGE should use this kit. Buyers whose systems require unbuffered UDIMMs, SODIMMs, a different voltage, or a lower maximum capacity should look at something else.

Questions about this item

Will the 288-pin DDR4 RDIMM modules fit the ASUS WS C621E SAGE motherboard slots?

Yes, the kit uses the 288-pin Registered RDIMM form factor that the ASUS WS C621E SAGE requires; it is not a UDIMM or SODIMM.

What is the correct population order for the six 32GB modules on this board?

Consult the ASUS WS C621E SAGE manual for the approved DIMM population sequence; the board's memory-controller rules dictate which slots must be filled first.

Do the modules need active cooling since they have no heat spreader?

The 1.2V DDR4 RDIMMs run without a heat spreader; ensure the chassis provides adequate airflow over the memory slots for sustained server loads.
