Exact DDR4-2666 ECC kit for ASUS WS C246 PRO

This 64GB kit contains four 16GB unbuffered ECC UDIMMs rated at DDR4 2666 (PC4-21300) with CL19 timing at 1.20V. The modules use a 2Rx8 organisation and 288-pin form factor so the motherboard recognises the full capacity at its rated speed.

Verify your board manual before ordering

Confirm the ASUS WS C246 PRO supports 64GB total capacity and the approved DIMM population order for four unbuffered ECC UDIMMs. The board must accept 288-pin DDR4 modules at 1.20V and CL19 latency for this kit to function correctly.

Suits workstation builders needing ECC reliability

Ideal for users who require error-correcting memory to prevent silent data corruption on the ASUS WS C246 PRO platform. Not for buyers who need registered RDIMMs, SODIMMs, non-ECC modules, or a different DDR generation.

Questions about this item

Does the 64GB kit contain four 16GB modules or do I need to buy extra sticks?

The package includes four 16GB DDR4 ECC UDIMM modules for a total of 64GB, so no additional sticks are required.

Should I choose a different speed or latency for the ASUS WS C246 PRO workstation?

This kit runs at DDR4 2666 (PC4-21300) with CL19 timing, matching the motherboard's rated specification exactly.

Will the 2666MHz rating actually run at that speed once installed in the WS C246 PRO?

Yes, the 2Rx8 unbuffered ECC modules operate at 1.20V and are spec-matched so the board recognises the full 64GB at the rated 2666MHz.
