Capacity and Configuration

This 512GB kit contains sixteen 32GB DDR5 registered DIMMs built for Dell PowerEdge R760XA servers. The modules are ECC registered with a 2Rx4 organisation to support high-density memory configurations in enterprise environments.

Sustained Workload Behaviour

Each module runs at 4800MT/s with CL40 latency at 1.10V and is stress tested under load before shipment. The registered design and ECC capability help maintain data integrity during continuous operation in mission-critical applications.

Pre-Installation Checks

Verify that your motherboard supports 288-pin DDR5 RDIMMs and can address 512GB across all populated slots. Confirm the system BIOS recognises 2Rx4 registered modules and that the platform accepts 1.1V DDR5 memory without additional configuration.

Questions about this item

How much power will the 1.10 V DDR5 registered kit draw when the server runs continuously?

Each module operates at 1.10 V, the standard DDR5 voltage, so total power scales with the 16 installed DIMMs and the workload; the registered buffer adds a small overhead compared with unbuffered memory.

What motherboard features are required for these 288-pin ECC RDIMMs to function?

The board must provide 288-pin DDR5 slots, support registered ECC RDIMMs, and accept 2Rx4 modules at 4800 MT/s; consumer boards that only take unbuffered non-ECC DIMMs will not work.

Can I mix these 2Rx4 CL40 modules with existing 1Rx4 or 2Rx8 DDR5 RDIMMs in the same Dell PowerEdge R760XA?

Mixing ranks is possible if the platform's memory controller allows it, but Dell's qualified configurations usually recommend identical rank-per-channel layouts for maximum stability and performance.
