NEMIX RAM 256GB (4×64GB) DDR4 3200 ECC RDIMM CL22 1.2V memory upgrade

256GB DDR4 ECC RDIMM kit

This 256GB kit contains four 64GB DDR4 3200 ECC registered DIMMs built for MSI WRX80 motherboards. It targets IT professionals and system builders who need maximum registered capacity in a validated four-module configuration. Each module operates at 1.2V with CL22 latency and uses a 2Rx4 organisation.

Registered DDR4 3200 platform limits

Registered DDR4 3200 modules require a motherboard chipset and CPU memory controller that support registered ECC operation at this data rate. Population rules for quad-channel WRX80 boards dictate specific slot loading order; exceeding the board's ranked-DIMM limit per channel will prevent boot or force down-clocking. The 288-pin RDIMM form factor is mechanically incompatible with standard unbuffered UDIMM slots.

2Rx4 quad-rank density constraint

The 2Rx4 dual-rank x4 organisation across four 64GB modules determines whether the platform's memory controller can address the full 256GB without reducing speed or disabling ranks. Buyers whose MSI WRX80 board specifies a maximum rank count per channel lower than eight cannot use this kit at its rated capacity or frequency.
