384GB DDR4 ECC RDIMM Kit

This 384GB kit contains twelve 32GB DDR4 2933MHz registered ECC RDIMMs. It is built for the ASUS WS C621E SAGE workstation motherboard and matches the board's required 2Rx8 rank, 1.2V voltage, and CL21 timing. The registered design allows all slots to be populated at full rated speed.

Installation and Common Issues

The 288-pin RDIMM modules install vertically into the motherboard's DDR4 slots following the population order in the ASUS WS C621E SAGE manual. Because the kit uses registered ECC memory, the system must support ECC and registered DIMMs; a board that only accepts unbuffered UDIMMs will not POST. Verify the approved DIMM sequence before seating all twelve sticks.

Who This Suits and Who Should Look Elsewhere

This kit suits administrators upgrading an ASUS WS C621E SAGE workstation to its maximum validated capacity with matched, server-grade modules. Buyers who need a different total capacity, a different speed grade, or memory for a motherboard that does not support registered ECC DDR4 should look elsewhere.

Questions about this item

How do I verify the kit runs at DDR4 2933 CL21 with ECC active after installation?

Enter the BIOS or UEFI and confirm the memory speed shows 2933 MT/s, CAS latency reads CL21, voltage is set to 1.20 V and ECC is reported as enabled for all 384 GB across the 12 slots.

What exactly ships in the MR23400-328K12 kit and is anything else required?

The box contains twelve 32 GB 288-pin DDR4 RDIMM modules rated PC4-23400 2Rx8 1.2 V CL21; no heat spreaders, cables or additional parts are included and nothing else is needed for a supported ASUS WS C621E SAGE motherboard.

Which capacity version should I choose for the ASUS WS C621E SAGE to reach the full 384 GB limit?

Select the 384 GB kit (12 × 32 GB) — it matches the board's maximum supported capacity and population rules, whereas smaller kits would leave slots empty and reduce total memory.
