Exact-match DDR4 ECC module

This 8GB DDR4-2666 UDIMM delivers ECC error correction at CL19 and 1.2V for the ASUS Pro WS C246-ACE workstation motherboard. The 1Rx8 unbuffered organisation matches the board's memory controller so the full capacity is recognised at rated speed. Builders needing registered DIMMs or non-ECC memory cannot use this module.

Verified fitment for C246-ACE

The 288-pin unbuffered ECC form factor is the exact type the ASUS Pro WS C246-ACE requires, not an RDIMM or SODIMM. Population order and maximum capacity depend on the motherboard manual, so confirm the supported configuration before installation. Systems that demand registered or load-reduced DIMMs are not supported.

Low-voltage operation without spreaders

Running at 1.20V keeps power draw modest and thermals manageable inside a workstation chassis. No heat spreader is fitted, so airflow across the bare PCB handles cooling silently. Modules needing active cooling or higher voltage rails fall outside this design.

Questions about this item

Will the CL19 latency hold steady during extended workloads on the ASUS Pro WS C246-ACE?

Yes, the module runs at its rated DDR4 2666 speed with CL19 timing and 1.20 V, so the memory controller sees the exact latency it expects without downclocking.

Does the lack of a heat spreader cause higher temperatures or fan noise under all-day operation?

The UDIMM operates at standard 1.2 V DDR4 power and is unbuffered, so it stays within normal thermal limits for workstation boards without adding audible fan load.

Must the motherboard already support 288-pin DDR4 ECC unbuffered DIMMs for this kit to work?

Yes, the ASUS Pro WS C246-ACE requires 288-pin DDR4 ECC unbuffered UDIMMs, and this 1Rx8 module matches that exact form factor and voltage.
