Exact-match DDR4 ECC UDIMM for ASUS workstations

This 8 GB DDR4 2666 MHz module is built as an exact-match upgrade for the ASUS WS C246M PRO and WS C246M PRO/SE workstation motherboards. It uses the 288-pin unbuffered ECC UDIMM form factor those boards require, running at 1.2 V with CL19 timing and a 1Rx8 rank configuration. The memory controller will recognise the module at full capacity and at its rated speed without manual tuning.

Replaces non-ECC or slower DDR4 modules

The jump is worth it when your current DIMMs lack error-correcting code or run below 2666 MHz, because ECC detects and corrects single-bit errors on the fly to prevent silent data corruption and unplanned reboots. Matching the board's native PC4-21300 specification also avoids down-clocking that occurs with slower kits. Buyers who need registered RDIMM modules or SODIMM form factors cannot use this product.

Check motherboard manual for population rules

Before ordering, consult the ASUS WS C246M PRO or PRO/SE manual for supported total capacities, approved DIMM population order, and installation steps. The board's memory-population rules determine which slots must be filled first and the maximum capacity per channel. Verify that your system accepts unbuffered ECC UDIMMs rather than registered or load-reduced variants.

Questions about this item

Will this 288-pin DDR4 UDIMM fit the memory slots on my ASUS WS C246M PRO motherboard?

Yes, the module uses the 288-pin DDR4 UDIMM form factor required by the ASUS WS C246M PRO and WS C246M PRO/SE workstation boards.

What is the correct way to install this ECC UDIMM and which step is often missed?

Power off the system, open the chassis, align the notch on the 288-pin module with the slot key, press firmly until both retention clips click, then consult the motherboard manual for the approved DIMM population order.

Does the ECC function on this 1Rx8 module require any maintenance or replacement over time?

No, the on-die error-correcting code operates automatically without user maintenance and the module is covered by a lifetime replacement warranty.
