Exact-match DDR4 ECC kit for ASUS WS C246 PRO

This 32 GB kit contains two 16 GB DDR4 2666 modules built to the PC4-21300 standard. The 2Rx8 unbuffered ECC UDIMM design matches the memory controller expectations of the ASUS WS C246 PRO workstation motherboard.

32 GB capacity with ECC headroom

Two 16 GB DIMMs provide 32 GB of error-correcting memory for professional workloads that demand data integrity. The kit runs at 1.2 V with CL19 latency, so it fits within standard DDR4 power and timing envelopes for the supported platform.

288-pin unbuffered ECC form factor

The modules use the 288-pin UDIMM layout required by the ASUS WS C246 PRO, not registered or SO-DIMM variants. Buyers whose systems need RDIMM, LRDIMM or non-ECC memory cannot use this kit.

Questions about this item

Will this 32 GB DDR4-2666 CL19 kit run at its rated speed alongside my existing DDR4 ECC UDIMMs in the ASUS WS C246 PRO?

The kit is spec-matched to the ASUS WS C246 PRO and uses the exact 2666 MT/s, 1.2 V, CL19, 2Rx8 unbuffered ECC timings the board expects, so it will be recognized at full capacity and rated speed when populated per the manual.

How can I confirm the ECC function is active after installing the 2×16 GB ME21300-628K2 modules?

Enter the BIOS on the ASUS WS C246 PRO and verify that ECC is reported as enabled, then check the OS kernel logs or Windows Event Viewer for corrected-error counters that increment only when ECC is working.

What comes in the ME21300-628K2 box and do I need any extra parts to install it?

The box contains two 16 GB 288-pin DDR4 ECC UDIMM modules; no heat spreaders, cables, or tools are included and none are required for installation in the ASUS WS C246 PRO DIMM slots.
