System-specific DDR5 ECC RDIMM kit

This NEMIX RAM kit delivers 512 GB of DDR5 4800 registered ECC memory across sixteen 32 GB modules. It is built for the ASUS RS700A-E12-RS4U 1U dual-processor server and targets IT teams running virtualisation, databases or high-throughput workloads that demand maximum capacity with error correction.

Verify DIMM slots and BIOS revision

Confirm the server has sixteen available 288-pin DDR5 RDIMM slots and that the current BIOS supports 1Rx4 registered modules at 1.10 V. The platform must accept PC5-38400 speeds and CL40 latency without manual tuning. Without these checks the kit will not post or will fall back to a lower speed.

No heat spreaders or software included

The modules ship without heat spreaders, relying on the server’s directed airflow for cooling. No configuration utilities, firmware tools or diagnostic software are bundled; management is handled entirely through the system BIOS and IPMI. Buyers needing pre-applied thermal pads or a graphical tuning suite should look elsewhere.

Questions about this item

What comes in the 512GB kit and do I need any extra parts to install it in my ASUS RS700A-E12-RS4U server?

The kit contains sixteen 32GB DDR5 4800 ECC RDIMM modules. No additional parts are required; the modules plug directly into the server's 288-pin DDR5 slots.

Should I choose this 512GB 16x32GB kit or a different capacity for my ASUS RS700A-E12-RS4U?

This 512GB kit fills sixteen slots with 1Rx4 32GB modules running at DDR5 4800 CL40. Choose it when the server needs the full 512GB capacity across all available channels.

What does the DDR5 4800 CL40 rating mean for real-world performance in the RS700A-E12-RS4U?

The modules operate at 4800 MT/s with CAS latency 40 at 1.10V, delivering the rated PC5-38400 bandwidth when the server's memory controller runs them at the native DDR5 4800 speed.
