64GB DDR5 4800 ECC RDIMM 2Rx4 Server Module

This A-Tech module delivers 64GB of DDR5 4800MHz registered ECC memory for server and workstation platforms. It operates at the standard 1.10V DDR5 voltage with CL40 latency. The dual-rank 2Rx4 organisation uses a major-brand chipset and a 288-pin DIMM form factor. It is built as a compatible replacement for specific Hynix part numbers.

Suited for DDR5 RDIMM Slots Only

This memory fits systems that require registered DDR5 DIMMs with ECC support and accept a 2Rx4 configuration. It will not work in boards that take only unbuffered UDIMMs, nor in slots keyed for earlier DDR generations. Builders needing a different capacity, rank layout, or voltage should verify their platform specifications before ordering.

288-Pin DDR5 DIMM Form Factor

The module uses the 288-pin DDR5 DIMM interface, which is the single physical specification that determines whether it installs in a given server or workstation. Confirm the motherboard manual lists DDR5 RDIMM support and the correct pin count before purchase.

Questions sur cet article

Will the 64 GB DDR5 4800 ECC RDIMM need any firmware updates or periodic replacement in a server?

The module is a solid-state component with no moving parts and no firmware to update. Under normal server conditions it runs until a hardware fault occurs, at which point the single 64 GB stick is replaced.

What limit appears first when the Hynix-compatible 2Rx4 module runs at full load continuously?

The registered DDR5 4800 design operates at 1.10 V with CL40 latency. The first sustained-use boundary is the thermal envelope of the server chassis; the memory itself has no separate throttle point listed.

How much noise, heat or power does the 288-pin DDR5 4800 RDIMM add when the system runs all day?

The module draws power at the standard DDR5 1.10 V level and produces only the heat typical for a 64 GB registered DIMM. It adds no audible noise; cooling is handled by the server’s existing airflow.
