Exact-match DDR4 ECC UDIMM kit

This 32 GB kit contains two 16 GB DDR4 2666 modules built to the PC4-21300 standard. Each stick is a 288-pin unbuffered ECC UDIMM running at 1.2 V with CL19 latency and a 2Rx8 organisation. It is intended for workstations that require error-correcting memory and will only operate in systems that accept this exact specification.

Check motherboard manual and DIMM population

Verify that your motherboard supports 288-pin DDR4 ECC unbuffered UDIMMs and confirms the 2Rx8 rank structure at 2666 MT/s. Consult the manual for approved capacity limits, slot-filling order and any BIOS settings required for ECC operation before installing these modules.

Thermals noise and power draw

Modules run at the standard 1.2 V DDR4 voltage without a heat spreader, so they rely on case airflow for cooling. Power consumption stays within normal DDR4 UDIMM limits and the parts add no audible noise to the system. Ensure your chassis provides adequate ventilation over the DIMM slots.

Questions about this item

What comes in the box and is anything else required to install it?

The kit includes two 16 GB DDR4 2666 ECC UDIMM modules for a total of 32 GB. No extra parts are needed; the DIMMs plug directly into the motherboard's 288-pin slots.

How do I decide between this 32 GB kit and a different capacity?

Choose this 2 x 16 GB kit when your ASUS Pro WS C246-ACE board supports 32 GB and you want dual-channel performance with ECC error correction at the rated 2666 MT/s speed.

Will the advertised 2666 MHz speed actually run at that rate once installed?

Yes. The modules are spec-matched to the ASUS Pro WS C246-ACE memory controller with 2Rx8 rank, 1.20 V operation and CL19 timing, so the system recognises the full 32 GB and runs at the rated DDR4 2666 (PC4-21300) frequency.
