Exact-match 32 GB DDR4-2933 RDIMM

This NEMIX RAM module delivers 32 GB of DDR4-2933 memory in a 288-pin registered ECC form factor. It is built for the ASUS WS C621E SAGE workstation motherboard and runs at 1.2 V with CL21 latency. The 2Rx8 rank configuration matches the board's memory controller expectations.

Registered ECC with 2Rx8 rank

The module uses registered (buffered) architecture and on-die ECC to offload the memory controller and correct single-bit errors automatically. Its 2Rx8 organisation and 1.2 V operation are the precise electrical specifications the platform requires for full-capacity recognition at rated speed.

Suits ASUS WS C621E SAGE upgrades

This part fits builders populating the validated DIMM slots on that specific motherboard according to the manual's population rules. It does not suit systems needing unbuffered UDIMMs, SODIMMs, non-ECC memory, or a different DDR generation or pin count.

Questions about this item

Will the 2933 MHz speed run at its rated frequency on the ASUS WS C621E SAGE?

Yes, the module is an exact-match upgrade specified for DDR4-2933 on that motherboard, so the memory controller will recognise it at full capacity and run it at the rated 2933 MT/s.

Does the 288-pin RDIMM form factor limit which slots I can populate on this board?

The 288-pin Registered DIMM is the only form factor the ASUS WS C621E SAGE accepts; you must follow the manual's population order, but the module itself fits every supported slot.

What clearance does the module need since it has no heat spreader?

Without a heat spreader the module stays at the standard low-profile height, so it clears most CPU coolers and chassis air baffles that accommodate regular RDIMMs.
