  • 512 GB total capacity from four 128 GB modules enables maximum memory density
  • DDR5 4800 speed with CL40 latency delivers rated performance on the ASRock Rack GENOA2D24G-2L+
  • Registered ECC architecture corrects single-bit errors and stabilises fully populated slots
  • 2Rx4 organisation and 1.10 V voltage match the board's memory controller requirements exactly
  • 288-pin RDIMM form factor ensures correct physical and electrical fit for this server platform

Exact-match server upgrade

This 512 GB kit contains four 128 GB DDR5 4800 modules built to the precise rank, voltage and timing the ASRock Rack GENOA2D24G-2L+ memory controller expects. Each 288-pin RDIMM runs at 1.1 V with CL40 latency and 2Rx4 organisation so the board recognises full capacity at rated speed. Builders who need a different capacity or form factor such as UDIMM or SODIMM cannot use this kit.

Registered ECC stability

Registered buffering offloads the memory controller, allowing every slot to stay fully populated while ECC corrects single-bit errors on the fly to prevent silent data corruption and unplanned reboots. The modules ship without heat spreaders, relying on server chassis airflow for cooling. Buyers who require integrated thermal solutions or consumer-style XMP profiles will not find them here.

DDR5 4800 interface limits

The PC5-38400 standard sets a fixed 4800 MT/s data rate and 1.1 V operating voltage, so the kit cannot exceed this speed or voltage on the target platform. Population rules for the GENOA2D24G-2L+ dictate which slots must be filled first, and the manual must be consulted before installation. Systems that demand higher frequencies, lower latencies or non-ECC operation fall outside this specification.

Questions sur cet article

Will the 288-pin DDR5 RDIMM modules need any thermal paste or active cooling added later?

The kit ships without heat spreaders; standard server chassis airflow over the bare modules is the intended cooling method.

What electrical limit appears first when all four 128 GB DIMMs run continuously at 4800 MT/s?

The memory controller sees the full 512 GB registered load at 1.10 V, so the platform's maximum registered-DIMM capacity per channel is the governing ceiling.

How much extra power draw and fan noise should I expect from the 4-module kit under 24-hour workloads?

Each DIMM operates at 1.1 V DDR5 baseline; total incremental power is low enough that existing server fans typically maintain their idle curves.
