Server-Ready DDR5 Kit

This 512GB kit delivers eight 64GB DDR5-6400 Registered ECC RDIMMs built for the Supermicro X14DBG-LC+ motherboard. Each module runs at 1.1V with CL52 latency and a 4Rx4 organisation, matching the board's exact rank, voltage and timing requirements so the memory controller recognises full capacity at rated speed.

Enterprise Workloads Only

The registered architecture and on-die ECC suit databases, virtualisation hosts and compute clusters that demand continuous uptime and data integrity. Workstations or consumer boards that accept only unbuffered UDIMMs cannot use these modules, and any system limited to lower maximum densities should look elsewhere.

Build Integration

Populate all eight slots following the motherboard's approved DIMM sequence to enable the full 512GB at DDR5-6400. The registered design reduces electrical load on the memory controller, allowing every slot to run fully populated without signal degradation. No heat spreaders are fitted, so ensure chassis airflow meets the server vendor's thermal guidelines.
