Exact-fit DDR4 ECC UDIMM for ASUS WS C246 PRO

This 8 GB module matches the ASUS WS C246 PRO workstation motherboard memory specification. It is an unbuffered ECC UDIMM running at DDR4 2666 with CL19 timing and 1.2 V operation. The 1Rx8 rank layout ensures the memory controller recognises the full capacity at rated speed. Builders upgrading this specific board can install it without configuration guesswork.

DDR4 2666 bus and unbuffered ECC constraints

The DDR4 2666 interface caps peak bandwidth at the PC4-21300 rate, so workloads that scale with higher memory throughput will not benefit beyond this ceiling. Unbuffered ECC UDIMMs also limit maximum system capacity compared with registered DIMMs because the memory controller drives each module directly. Systems requiring larger total memory or faster data rates must use a different platform.

1Rx8 single-rank organisation decides fit

The single-rank 1Rx8 organisation is the decisive specification for this motherboard's memory population rules. If the board's qualified-vendor list calls for dual-rank modules or a different rank-per-channel limit, this DIMM will not operate correctly. Verify the manual's approved DIMM population order before purchase.

Questions about this item

Should I choose the 8GB DDR4-2666 CL19 kit or a different capacity for my ASUS WS C246 PRO?

The 8GB kit is an exact-match upgrade for the ASUS WS C246 PRO, delivering DDR4-2666 (PC4-21300) with 1Rx8 unbuffered ECC at 1.20V CL19 so the board recognises full capacity at rated speed.

What does DDR4-2666 (PC4-21300) actually deliver inside the WS C246 PRO?

The module runs at 2666 MT/s with CL19 timing and 1.20V, providing error-correcting unbuffered memory that the motherboard's memory controller accepts at its rated specification.

Is the 288-pin DDR4 ECC UDIMM interface the right one for this board, and what does it cap?

Yes — the WS C246 PRO requires 288-pin unbuffered ECC UDIMMs; this module matches that form factor and caps at DDR4-2666 (PC4-21300) with CL19 latency.
