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.

Questions about this item

Should I pick this 256GB kit or a smaller capacity for my MSI WS WRX80 motherboard?

This kit provides 256GB across four 64GB modules, filling four DDR4 slots on the MSI WS WRX80 board for maximum registered ECC capacity.

What does the 3200 speed rating mean once the modules are installed in a server?

The modules run at DDR4 3200 (PC4-25600) with CL22 latency at 1.2V, delivering the rated throughput when the motherboard enables the XMP or JEDEC profile.

How does the 288-pin RDIMM interface limit what I can use this memory with?

The 288-pin DDR4 RDIMM form factor only fits DDR4 registered DIMM slots; it cannot be used in UDIMM, SO-DIMM or DDR5 sockets.
