Workstation ECC memory kit

This 32GB kit contains four 8GB DDR4 ECC unbuffered UDIMM modules rated at 2666MHz with CL19 latency and 1.20V operation. It is built for professionals using the ASUS WS C246 PRO workstation motherboard who require error-correcting memory for data integrity.

Standard voltage thermal profile

Operating at the standard 1.20V DDR4 voltage, these modules run without heat spreaders and draw minimal power during typical workloads. The unbuffered design keeps electrical loading low, so system fan curves remain quiet under normal workstation use.

ASUS WS C246 PRO exact fit

The 288-pin UDIMM form factor, 1Rx8 rank structure, and DDR4-2666 specification match the memory-controller requirements of the ASUS WS C246 PRO motherboard. Builders needing registered DIMMs, SODIMMs, or non-ECC memory should choose a different kit.

Questions about this item

How do I install the four 288-pin DDR4 UDIMM modules on the ASUS WS C246 PRO, and which slot order do people get wrong?

Power off, open the case, and insert each 8 GB stick into the slots specified by the motherboard manual — typically the same-coloured pair first — pressing straight down until the latches click; the common mistake is populating the second channel before the first, which can prevent the full 32 GB from being recognised.

What maintenance or replacement will the 1Rx8 ECC UDIMM kit need later?

No routine maintenance is required; the modules have no heat spreaders to clean and no moving parts. If a DIMM ever fails, the lifetime replacement warranty covers a direct swap of the faulty 8 GB unit.

What limit appears first when the 2666 MHz CL19 kit runs sustained workloads?

The memory controller on the WS C246 PRO caps the data rate at 2666 MT/s, so throughput tops out at the rated PC4-21300 bandwidth; latency stays at CL19 and voltage remains at 1.20 V, so thermal throttling is not a factor with these unbuffered modules.
