Server Memory Kit

This 768GB DDR5 kit contains twelve 64GB registered ECC RDIMMs built for the ASUS RS520A-E12-RS12U single-socket 2U server. It targets administrators who need maximum memory capacity for virtualisation, databases or high-performance computing workloads. The modules run at 4800MT/s with CL40 latency at 1.1V.

Sustained Load Behaviour

ECC and registered buffering protect data integrity during continuous operation in mission-critical environments. The 2Rx4 organisation and major OEM DRAM from Samsung, Micron or Hynix maintain stability under heavy, prolonged memory pressure. Modules are stress-tested under load before shipping to verify reliability.

Build and Connectors

Each module uses a standard 288-pin DDR5 RDIMM form factor without a heat spreader, fitting the server's native DIMM slots directly. The 1.1V operating voltage aligns with the platform's power design. Twelve modules populate all available channels for the configured system.

Perguntas sobre este artigo

How much power does the 1.10V 768GB DDR5 4800 kit draw under sustained load?

At the rated 1.10 volts the 12 modules draw only modest power; registered DDR5 at 4800 MT/s typically stays well within standard server power budgets.

What must the ASUS RS520A-E12-RS12U already have for this 12x64GB kit to work?

The server needs 12 free 288-pin DDR5 RDIMM slots and a BIOS that supports 768 GB of registered ECC memory at 4800 MT/s.

Will the CL40 2Rx4 modules run at 4800 MT/s alongside older DDR5 DIMMs I keep?

The memory controller will down-clock all installed DIMMs to the lowest common speed and latency, so older DDR5 will force this kit to run slower.
