Exact-match DDR4 ECC UDIMM for ASUS C246-ACE

This 16 GB DDR4-2666 module is built to the precise rank, voltage and timing the ASUS Pro WS C246-ACE workstation motherboard expects. It installs as a 288-pin unbuffered ECC UDIMM so the board recognises full capacity at rated speed without manual tuning.

CL19 at 1.2 V decides compatibility

The memory controller on this platform requires CAS latency 19 at 1.20 V with a 2Rx8 organisation. Any different latency, voltage or rank structure will prevent the system from booting or force a down-clock that wastes the installed capacity.

Passive operation keeps thermals simple

Without a heat spreader the module relies on chassis airflow and runs at the standard 1.20 V DDR4 voltage. Power draw stays low, noise is limited to case fans, and temperatures remain within normal limits for typical workstation workloads.

Questions about this item

Will the 2666 MHz rating run at that speed in my ASUS Pro WS C246-ACE?

The module is spec-matched to the board's DDR4 2666 (PC4-21300) memory controller, so it is recognized at full capacity and runs at the rated 2666 MHz with CL19 timing.

Does the 288-pin ECC UDIMM interface limit me to unbuffered modules only?

Yes, this is a 288-pin unbuffered ECC UDIMM; the motherboard requires this exact form factor and will not accept registered RDIMMs or SODIMMs.

What physical clearance does the 16 GB stick need inside the case?

The module has no heat spreader, so it fits the standard 288-pin DDR4 UDIMM slot height used by the ASUS Pro WS C246-ACE without extra clearance.
