512GB DDR5 5600 ECC RDIMM kit

This 512GB memory kit contains four 128GB DDR5 5600 CL46 4Rx4 ECC registered DIMMs. It is built for servers and workstations that require registered error-correcting memory at the DDR5 5600 standard.

DDR5 5600 registered ECC constraint

Registered ECC RDIMMs operate at 1.1V and present a 4Rx4 organisation to the memory controller. The platform must support DDR5 5600 registered ECC modules with this rank geometry and voltage.

ASUS Pro WS WRX90E SAGE SE compatibility

This kit is validated for the ASUS Pro WS WRX90E SAGE SE workstation motherboard. Systems using a different motherboard or an unregistered DIMM type will not accept these modules.

Questions about this item

Should I choose the 4×128 GB kit or a different capacity for my ASUS Pro WS WRX90E SAGE SE workstation?

The kit provides 512 GB total across four 128 GB modules, matching the board's eight-channel architecture for full bandwidth.

What does the 5600 MT/s rating deliver once installed in the workstation?

The modules run at DDR5 5600 (PC5-44800) with CL46 latency at 1.10 V, giving the rated throughput on the qualified platform.

How does the 288-pin DDR5 RDIMM interface limit performance in practice?

The registered 288-pin DDR5 RDIMM form factor caps speed to the platform's validated 5600 MT/s and requires ECC-enabled server chipsets.
