32GB DDR4 2666 ECC UDIMM

This 32 GB DDR4 2666 module delivers 2666 MT/s at CL19 and 1.20 V. It uses a 2Rx8 unbuffered ECC UDIMM layout on 288 pins. The memory is built for the ASUS Pro WS C246-ACE workstation motherboard.

Fitment and limits

Suits owners of that ASUS board who need exact-match ECC UDIMM capacity. Builders requiring registered RDIMMs, non-ECC modules, SODIMM form factor or speeds above 2666 MT/s should look elsewhere.

Deciding spec: 2Rx8 ECC UDIMM

The single specification that decides fitment is the 2Rx8 unbuffered ECC UDIMM organisation. Your motherboard must accept this rank, voltage and pin layout; otherwise the module will not be recognised or run at rated speed.

Questions about this item

Will this 32GB DDR4 2666MHz ECC UDIMM work in my ASUS Pro WS C246-ACE motherboard?

Yes, the module is verified for the ASUS Pro WS C246-ACE and matches the board's required 288-pin unbuffered ECC UDIMM form factor, 2Rx8 rank, 1.2V voltage and CL19 timing.

Can I add this 2Rx8 ECC UDIMM alongside my existing 1Rx8 DDR4 2666MHz sticks?

Mixing ranks is possible but the motherboard manual should be consulted for approved population order; the board may run all slots at the lowest common speed and rank configuration.

How do I confirm the 32GB kit is running at DDR4 2666MHz with ECC active after installation?

Enter the BIOS or UEFI and check the memory information screen — it should report 32GB, 2666MHz (PC4-21300), CL19, 1.2V and ECC enabled.
