128GB DDR4-2933 ECC RDIMM kit

This 128GB kit contains four 32GB DDR4-2933 Registered ECC RDIMMs built for the ASUS WS C621E SAGE workstation motherboard. Each module runs at 1.2V with CL21 timing and a 2Rx8 organisation. The registered buffer and error-correcting code are designed for stable, fully populated server operation.

Verify motherboard population rules

Check the ASUS WS C621E SAGE manual for approved DIMM population order, maximum supported capacity per slot, and any BIOS version requirements before installing. The kit uses 288-pin RDIMM form factor; it will not fit UDIMM or SODIMM slots. Ensure your system accepts Registered ECC modules at the rated speed.

Suited for fully populated ECC workloads

Ideal for users upgrading the named workstation to its full 128GB Registered ECC configuration for virtualization, rendering or data-integrity tasks. Not suitable for systems that require unbuffered UDIMMs, non-ECC memory, SODIMM form factor, or a different DDR generation. Builders needing lower capacity or consumer-grade modules should consider other options.

Questions about this item

Does the 128GB kit include all four 32GB modules or must I buy extra sticks?

The box contains the full 128GB kit as four matched 32GB DDR4 2933MHz RDIMMs; nothing else is required to reach the stated capacity.

Should I pick the 2Rx8 CL21 1.2V version or a different rank and latency for the ASUS WS C621E SAGE?

Choose the 2Rx8 CL21 1.2V modules listed; they match the board's qualified rank, voltage and timing so the memory controller recognises every slot at full speed.

Will the PC4-23400 rating actually deliver 2933 MT/s once installed in the workstation?

Yes — the modules are specced to DDR4 2933 (PC4-23400) and the registered ECC design lets the C621E SAGE run all four slots populated at that rated data rate.
