Suitable servers and workloads

This 512GB kit fits the ASUS RS700-E11-RS4U dual-socket 1U server. Registered ECC RDIMMs with 2Rx4 organisation provide the density and error correction that virtualisation, database and compute clusters require. Buyers needing unbuffered UDIMMs or non-ECC memory for workstations should look elsewhere. Modules without heat spreaders also rely on chassis airflow, so systems with restricted cooling need verification.

Deciding specification

The registered ECC RDIMM form factor is the single specification that determines compatibility. Only platforms that accept 288-pin DDR5 registered DIMMs with 2Rx4 ranks at 1.1V can use this kit. Consumer motherboards and most workstations do not support registered memory, so the module type alone confirms whether this upgrade will work.
