NEMIX RAM 8GB DDR4 2666MHz ECC UDIMM CL19 1Rx8 memory upgrade

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.
