Four green DDR4 ECC UDIMM modules without heat spreaders

NEMIX RAM

NEMIX RAM DDR4 64GB 4x16GB ECC UDIMM 2666 CL19 ASUS Pro WS C246-ACE

SKU CH-SQ6Z-MN6AT

A 64 GB kit of four 16 GB DDR4 ECC UDIMM modules running at 2666 MHz CL19 and 1.2 V, validated for the ASUS Pro WS C246-ACE workstation motherboard

  • Capacity64GB (4 x 16GB)
  • Type288-Pin DDR4 ECC UDIMM
  • SpeedDDR4 2666 (PC4 21300)

Size 64GB 4X16GB

  • 64 GB capacity across four 16 GB modules for high-density workstation memory
  • ECC protection detects and corrects single-bit errors to prevent silent data corruption
  • DDR4 2666 MHz CL19 at 1.20 V matches the board's rated speed and timing
  • 288-pin unbuffered UDIMM form factor fits the ASUS Pro WS C246-ACE exactly
  • Lifetime replacement warranty and free US-based technical support included

Exact-match upgrade kit

This 64 GB kit contains four 16 GB DDR4 ECC unbuffered UDIMM modules rated at 2666 MT/s with CL19 timings at 1.20 V. It is built to the precise rank, voltage and timing the ASUS Pro WS C246-ACE workstation motherboard expects so the memory controller recognises the full capacity at rated speed.

Thermals noise and power

The modules operate at the standard DDR4 voltage of 1.20 V and have no heat spreader, relying on case airflow for cooling. With no active cooling components the kit adds no audible noise and its power draw remains within the normal range for 288-pin DDR4 ECC UDIMMs at this frequency.

What the bundle changes

The package delivers a matched set of four identical 2Rx8 modules that follow the board's memory-population rules for full-capacity operation. ECC functionality detects and corrects single-bit errors on the fly to prevent silent data corruption and unplanned reboots during critical workloads.

Perguntas sobre este artigo

How do I install the 288-pin DDR4 UDIMM kit on the ASUS Pro WS C246-ACE, and which step is often missed?

Power off the system, open the case, and insert each 16 GB module into the slots specified by the motherboard manual in the correct population order; the step most often missed is consulting that manual for the exact slot sequence before installing all four sticks.

What maintenance or replacement will the ECC UDIMM kit need over its service life?

No routine maintenance is required; the modules are covered by a lifetime replacement warranty, so a stick would only be swapped if a hardware fault develops.

What limit appears first when the 2666 MHz CL19 kit runs under sustained load?

The memory controller on the C246-ACE platform caps operation at the rated 2666 MT/s and CL19 timing, so sustained workloads cannot exceed that speed or latency envelope.
