Server Memory Kit

This kit provides 1TB of DDR5 memory across sixteen 64GB registered ECC RDIMM modules. It is built for the ASUS RS700A-E12-RS12U 1U dual-processor server platform where maximum capacity and error correction are required.

Compatibility Check

Verify that your system is the exact ASUS RS700A-E12-RS12U model before ordering. Confirm the motherboard has sixteen available 288-pin DDR5 slots and supports registered ECC modules at 4800MHz with CL40 latency and 1.10V operation.

Build Integration

The modules install directly into the server's DDR5 RDIMM slots without heat spreaders, fitting the dense 1U form factor. Registered buffering reduces electrical load on the memory controller, allowing all sixteen slots to be populated for full 1TB capacity.
