Size 64GB 2X32GB

  • Error-correcting ECC memory prevents silent data corruption and crashes
  • Exact-match 64 GB kit runs at full 2666 MHz CL19 on the ASUS Pro WS C246-ACE
  • Two 32 GB dual-rank UDIMMs populate the board's required 288-pin slots correctly
  • Low 1.2 V operation reduces power draw and heat in workstation builds
  • Built with major OEM DRAM chips for consistent reliability

Exact-match DDR4 ECC kit for ASUS Pro WS C246-ACE

This 64 GB kit contains two 32 GB DDR4 2666 UDIMM modules built to the exact rank, voltage and timing the motherboard expects. It is intended for workstation builders who need ECC reliability on this specific ASUS platform.

2Rx8 unbuffered ECC at 1.2 V CL19

Each module is a 288-pin DDR4 2666 (PC4-21300) UDIMM with 2Rx8 organisation, unbuffered ECC, 1.20 V operating voltage and CL19 latency. The board requires this precise combination; RDIMM or SODIMM variants will not fit or function.

Standard-voltage DDR4 thermals without spreaders

The modules run at the JEDEC-standard 1.2 V with no heat spreaders, so power draw and heat output remain at baseline DDR4 levels. Acoustic profile is silent because there are no active cooling components on the DIMMs.

Questions about this item

Will the 2666 MHz speed run at that frequency on the ASUS Pro WS C246-ACE?

The kit is rated DDR4 2666 (PC4-21300) and the motherboard supports that speed, so the modules will operate at their rated frequency.

Is this ECC unbuffered UDIMM the correct module type for the board?

Yes, the ASUS Pro WS C246-ACE requires 288-pin DDR4 ECC unbuffered UDIMMs, which is exactly what this kit provides.

Does the 2Rx8 dual-rank layout fit the board's DIMM population rules?

The kit uses two 32 GB 2Rx8 modules, matching the board's supported rank and capacity per slot for full 64 GB operation.
