512GB DDR5 kit for ASUS RS720Q-E11-IM

This 512GB kit contains four 128GB DDR5 4800 registered ECC RDIMMs built for the ASUS RS720Q-E11-IM 2U4N immersion-cooling server. It targets IT teams who need maximum density in a validated configuration.

288-pin registered modules without heat spreaders

Each module is a 288-pin 4Rx4 RDIMM operating at 1.1V with CL40 latency. The registered design and error-correcting code protect data integrity under sustained load. The bare PCB fits the tight clearances of the immersion-cooled chassis without extra height.

Four matched modules in a single kit

The package delivers four factory-matched 128GB sticks so the server populates all channels identically. This eliminates mixing risks and simplifies qualification for mission-critical deployments.
