Precision 64GB DDR4-2933 RDIMM

This NEMIX RAM module delivers 64GB of DDR4-2933 (PC4-23400) registered ECC memory in a single 288-pin RDIMM. It operates at 1.20V with CL21 latency and a 2Rx4 rank structure. The specification matches the exact voltage, timing and rank organisation your server memory controller expects for full-speed recognition.

Verified ASUS WS C422 fit

Verified compatibility covers the ASUS WS C422 SAGE/10G and WS C422 PRO/SE workstation motherboards. Registered architecture offloads the memory controller so every slot runs fully populated at rated capacity, while ECC corrects single-bit errors on the fly. Builders using consumer UDIMMs, SODIMMs or non-ECC modules should look elsewhere because the platform requires registered ECC RDIMMs.

2Rx4 registered ECC at 1.20V

The single specification that decides fit is the 2Rx4 registered ECC organisation at 1.20V. Your motherboard manual lists supported capacities, approved DIMM population order and installation steps; consult it before purchase to confirm this module meets those rules.

Questions about this item

Will the 288-pin RDIMM fit the ASUS WS C422 SAGE/10G motherboard?

Yes, the 288-pin DDR4 RDIMM form factor matches the memory slots on the ASUS WS C422 SAGE/10G and WS C422 PRO/SE workstation motherboards.

What is the correct installation order when populating all slots with these 2Rx4 modules?

Follow the motherboard manual's DIMM population sequence; registered ECC RDIMMs must be installed in the specific slot order the manual defines for full-capacity recognition.

Does the lack of a heat spreader affect long-term reliability under continuous server loads?

The modules use major OEM chips rated for 1.20 V operation without a spreader; adequate chassis airflow keeps temperatures within spec for continuous operation.
