Server Memory Kit

This NEMIX RAM kit supplies 512 GB of DDR5 capacity across eight 64 GB registered DIMMs. It is built for the ASUS RS520A-E12-RS24U single-socket 2U server and targets IT teams running memory-intensive workloads in that specific platform.

Build Integration

Each module uses the 288-pin DDR5 RDIMM form factor with 2Rx4 organisation and operates at 1.1 V. Registered buffering and on-die ECC reduce electrical load on the memory controller, freeing the CPU to handle larger datasets without instability.

Suitability

This kit suits administrators who need a validated 512 GB upgrade for the named ASUS 2U server and want a single part number for all eight slots. Builders using a different chassis, a dual-socket board, or a platform that requires unbuffered UDIMMs should look at other memory solutions.

Questions about this item

Will the 1.10 V DDR5 modules stay stable during 24-hour workloads?

The kit runs at the standard 1.10 V for DDR5, so power draw and heat remain within normal server DIMM limits.

How much heat does the 512 GB kit produce under continuous load?

Eight 64 GB RDIMMs at 4800 MT/s and CL40 generate typical registered-DIMM thermals; no heat spreader is fitted, so chassis airflow handles cooling.

Does the ASUS RS520A-E12-RS24U need a specific BIOS version before installing this memory?

The modules are validated for the RS520A-E12-RS24U; consult the ASUS motherboard manual for any required BIOS update before installation.
