Two green DDR4 RDIMM modules without heat spreaders

NEMIX RAM

NEMIX RAM 128GB 2x64GB DDR4 2933MHz PC4-23400 CL21 2Rx4 1.2V ECC RDIMM ASUS WS C621E SAGE

SKU CH-4SBW-Q3YA3

128GB DDR4 2933MHz ECC RDIMM kit with 2Rx4 registered modules for ASUS WS C621E SAGE workstations

  • Capacity128GB (2 x 64GB)
  • Type288-Pin DDR4 RDIMM
  • SpeedDDR4 2933 (PC4 23400)
  • CAS LatencyCL21
  • Voltage1.20V

Size 128GB 2X64GB

  • 128GB kit enables full-capacity workloads with two 64GB modules
  • DDR4 2933MHz PC4-23400 speed matches board-rated frequency exactly
  • Registered ECC architecture corrects single-bit errors for production stability
  • 2Rx4 CL21 1.20V spec aligns with memory controller expectations
  • 288-pin RDIMM form factor fits ASUS WS C621E SAGE motherboard slots

Exact-Match Server Upgrade

This 128GB kit delivers two 64GB DDR4 2933MHz modules built to the PC4-23400 standard with CL21 latency and 1.20V operation. The 2Rx4 registered ECC RDIMM design matches the precise rank, voltage and timing the ASUS WS C621E SAGE workstation motherboard expects for full-capacity recognition at rated speed.

Registered ECC Architecture

Registered buffering offloads the memory controller so every populated slot runs stably at maximum capacity while ECC corrects single-bit errors on the fly, preventing silent data corruption and unplanned reboots in production workloads. The 288-pin RDIMM form factor is the only type this board accepts; UDIMM or SODIMM modules will not fit or function.

Suited For And Not Suited For

Ideal for administrators expanding an ASUS WS C621E SAGE workstation to 128GB with validated, spec-matched modules that install without population-order guesswork. Not suitable for systems requiring UDIMM or SODIMM form factors, for boards that do not support registered ECC DDR4, or for any platform outside the verified compatibility list.

Questions about this item

Will the 2Rx4 ECC RDIMM modules need replacement after a certain period?

The modules have no moving parts and are built for continuous server operation; they typically last the lifetime of the ASUS WS C621E SAGE system unless a rare defect occurs.

What limits sustained throughput on the DDR4 2933MHz CL21 kit?

The CAS latency of 21 cycles and the 2933 MT/s data rate set the maximum sustained bandwidth the memory controller can achieve.

How much heat and power do the 1.2V registered DIMMs produce under all-day load?

Each 64 GB module runs at 1.2 volts with registered buffering, keeping power draw and thermal output low enough for standard server airflow.
