System-specific ECC UDIMM kit

This 16 GB kit contains two 8 GB DDR4 2666 MHz unbuffered ECC UDIMMs built to the exact rank, voltage and timing the ASUS Pro WS C246-ACE workstation motherboard expects. It is for professionals who need verified, error-correcting memory that the board will recognise at full capacity and rated speed.

Build integration and slot usage

The 288-pin UDIMM form factor matches the board's required module type; it is not an RDIMM or SODIMM. Installing the pair occupies two DIMM slots and satisfies the motherboard's population rules, leaving remaining slots free for future expansion if the platform supports higher total capacity.

Thermals, noise and power draw

Modules run at 1.2 V with no heat spreader, so they add minimal thermal load and produce no audible noise. Power draw stays low during typical workstation workloads, and the ECC function corrects single-bit errors on the fly without increasing voltage or heat.

Questions about this item

Will the 1.20V DDR4 modules hit a thermal limit during continuous all-day workloads?

The kit runs at standard 1.20V DDR4 voltage with no heat spreader, so sustained use stays within normal JEDEC thermal limits for unbuffered ECC UDIMMs.

How much noise or extra heat does the 2666MHz CL19 kit add when the system runs 24/7?

Memory modules are passive components; they produce no audible noise and only minimal heat at 1.20V, adding negligible thermal load to the chassis.

Does the ASUS Pro WS C246-ACE motherboard need a specific BIOS version or CPU to recognise the 2x8GB 1Rx8 ECC UDIMM kit?

The board must support DDR4 2666 unbuffered ECC UDIMMs; consult the motherboard manual for approved DIMM population order and any required BIOS update.
