  • ECC protection stops silent data corruption
  • Exact DDR4-2666 spec matches ASUS WS C246 PRO
  • 16GB dual-channel kit runs at rated CL19 speed
  • Unbuffered 288-pin UDIMM fits board slots
  • Major OEM chips ensure consistent quality

Exact-match DDR4 ECC kit

This 16 GB kit contains two 8 GB DDR4 2666 MHz modules built to the PC4-21300 standard with CL19 latency and 1.2 V operation. It targets workstation owners who need error-correcting memory for the ASUS WS C246 PRO motherboard.

Unbuffered 288-pin UDIMM form

Each stick is an unbuffered ECC UDIMM using a 1Rx8 organisation and major-brand Samsung, Micron or Hynix chips. The 288-pin layout matches the board's DIMM slots directly, so no adapter or registered alternative is required.

CL19 timing at 2666 MHz

The modules run at DDR4-2666 with a CAS latency of 19, the exact timing the memory controller expects for full-speed recognition. Builders using RDIMM-only platforms or non-ECC consumer boards cannot use this kit.

Questions about this item

What DDR4 speed and PC4 rating does this 16GB kit run at?

The kit operates at DDR4 2666 with a PC4-21300 data rate, so the memory controller will run it at 2666 MT/s when the board supports that speed.

Which motherboard form factor and slot type does this 288-pin UDIMM kit require?

It needs a standard desktop motherboard with two 288-pin DDR4 DIMM slots that accept unbuffered ECC UDIMMs; the ASUS WS C246 PRO Workstation board is the verified platform.

How are the two 8GB modules installed, and what population rule do builders often miss?

Insert each module into the slots specified by the motherboard manual for a 2-DIMM configuration; the common mistake is populating the wrong pair of slots and preventing the system from booting at full capacity.
