NEMIX RAM DDR4 ECC RDIMM 256GB (4x64GB) 2933MHz CL21 2Rx4 1.2V 288-Pin Registered Memory Upgrade

SKU CH-3C8J-EAFJS

A 256GB registered ECC DDR4 kit of four 64GB modules at 2933MHz CL21 1.2V for the ASUS WS C621E SAGE workstation motherboard

  • Capacity256GB (4 x 64GB)
  • Type288-Pin DDR4 RDIMM
  • SpeedDDR4 2933 (PC4 23400)
  • CAS LatencyCL21
  • Voltage1.20V
  • ECCYes

Size 256GB 4X64GB

  • 256 GB kit populates four slots at full rated speed
  • 2933 MHz DDR4 matches the controller spec exactly
  • Registered ECC design corrects single-bit errors on the fly
  • 20 V operation keeps power draw low per module
  • 288-pin RDIMM form factor fits the ASUS WS C621E SAGE motherboard

Exact-match server upgrade

This kit delivers 256GB of DDR4 ECC registered memory in four 64GB modules built to the precise rank, voltage and timing the memory controller expects. It is intended for administrators upgrading an ASUS WS C621E SAGE workstation that requires fully populated registered DIMM slots at rated speed.

DDR4-2933 registered limits

The DDR4-2933 registered interface tops out at this data rate and requires a motherboard wired for 288-pin RDIMMs; unbuffered or SO-DIMM modules will not fit or function. Population rules on the target board dictate which slots must be filled first, so full 256GB capacity is only reached when the manual's approved order is followed.

Replaces partial or slower kits

This kit replaces smaller-capacity or mixed-speed DDR4 registered sets that leave slots empty or force the controller to down-clock. The jump is worth it when the workload needs the full 256GB at 2933MHz with ECC protection and the board's population guide confirms four 64GB 2Rx4 modules are supported.

商品問答

Should I choose the 256GB kit or buy single 64GB modules to fill the ASUS WS C621E SAGE?

The 256GB kit provides four matched 64GB RDIMMs tested together for 2Rx4 rank consistency, ensuring the memory controller recognises the full capacity at DDR4-2933 without population-order issues.

What does the 2933MHz rating mean once the kit is installed in the workstation?

The modules run at DDR4-2933 (PC4-23400) with CL21 latency at 1.2V, delivering the exact bandwidth and timing the C621E chipset expects when all four slots are populated.

How does the 288-pin RDIMM interface affect maximum capacity on this motherboard?

Registered DIMMs buffer address and command signals, allowing the board to run all four slots at 64GB each for 256GB total, while ECC corrects single-bit errors in real time.
