Exact-match DDR4 ECC kit for ASUS workstations

This 32 GB kit contains four 8 GB DDR4-2666 ECC UDIMM modules rated at CL19 and 1.2 V. It is built as a direct replacement for the ASUS WS C246M PRO and WS C246M PRO/SE workstation motherboards, matching the 288-pin unbuffered form factor and 1Rx8 rank layout those boards require.

ECC protection prevents silent data errors

Each module implements error-correcting code that detects and corrects single-bit faults in real time, stopping silent corruption and unplanned reboots before they affect workloads. The kit ships without heat spreaders, keeping the low-profile UDIMM height compatible with dense workstation layouts.

Verify DIMM population rules before installing

Motherboard manuals define supported capacities, approved slot order and maximum modules per channel; exceeding those limits can prevent the system from posting or force reduced speeds. Confirm your specific board revision accepts four 8 GB unbuffered ECC UDIMMs at DDR4-2666 before ordering.

Questions about this item

Will the ECC UDIMM modules need periodic replacement or firmware updates?

The modules are passive DDR4 ECC UDIMM components with no firmware; they require no scheduled replacement under normal operation.

What thermal or voltage limit is reached first during continuous full-load use?

The kit runs at a fixed 1.20 V with CL19 timing and no heat spreader; sustained load stays within the standard DDR4 voltage envelope.

How much noise and heat does the 4x8GB kit produce when the workstation runs all day?

The unbuffered UDIMMs have no moving parts and no heat spreader, so they add negligible acoustic noise and only modest heat at 1.20 V.
