  • 288-pin form factor fits ASUS WS C246M PRO/SE slots
  • Major-brand Samsung Micron Hynix chips ensure consistent quality

Exact-match DDR4 ECC kit for ASUS workstations

This 16 GB kit delivers two 8 GB DDR4 2666 UDIMMs with ECC, 1.2 V operation and CL19 timing. The modules are validated for the ASUS WS C246M PRO and WS C246M PRO/SE motherboards so the memory controller recognises the full capacity at rated speed without manual adjustment.

Suited for ECC workloads.

Builders who need error-correcting memory for data-integrity tasks such as scientific computing, rendering or server workloads will benefit from the on-the-fly correction. Systems that require registered DIMMs, SODIMMs or non-ECC unbuffered modules cannot use this kit.

Fits 288-pin UDIMM slots on the C246 platform

The 288-pin unbuffered ECC form factor matches the board's DIMM sockets and population rules, leaving no need for adapters or BIOS workarounds. Installing the pair frees remaining slots for future capacity expansion while keeping the memory subsystem within the board's validated configuration.

Questions about this item

What motherboard must I already have for this 288-pin DDR4 2666 kit to work?

The kit is validated for the ASUS WS C246M PRO and WS C246M PRO/SE workstation motherboards that accept 288-pin unbuffered ECC UDIMMs.

Will this 1Rx8 CL19 kit run alongside any existing DDR4 2666 ECC UDIMMs I keep in the same board?

Yes, if the installed modules are also DDR4 2666 unbuffered ECC UDIMMs at 1.2 V, the memory controller will operate all DIMMs at the common 2666 MT/s speed and CL19 timing.

How can I confirm the 16 GB kit is recognised at full speed after installation?

Enter the BIOS or UEFI and verify the memory frequency reads 2666 MHz, the capacity shows 16 GB, and ECC status is reported as enabled.
