64GB DDR4 ECC RDIMM for servers
This module provides 64GB of DDR4 3200MHz registered ECC memory in a 288-pin form factor. It is built for enterprise servers and workstations that require error-correcting, buffered RAM to maintain data integrity under heavy workloads. The dual-rank 2Rx4 organisation and CL22 latency support stable operation in multi-module configurations. Certified for Supermicro platforms, it suits IT professionals upgrading compatible systems.
Upgrade from lower-capacity or non-ECC modules
Replacing smaller RDIMMs or unbuffered memory with this 64GB stick increases total system capacity and adds hardware error correction. The jump is worthwhile when applications demand larger datasets in memory or when the platform requires registered DIMMs for signal integrity across populated slots. Systems limited to lower densities or lacking ECC support cannot use this module, so verification against the motherboard qualified-vendor list is essential before purchase.
Steady throughput under sustained workloads
Operating at the standard 1.20V DDR4 voltage, the module maintains its rated 3200MHz speed during extended compute tasks such as virtualisation, database caching or scientific processing. Registered buffering reduces electrical load on the memory controller, helping consistent timing when all channels are fully populated. Thermal characteristics follow the DDR4 specification for server environments, allowing continuous operation without throttling in properly cooled chassis.

Questions about this item
What slot type does the 288-pin RDIMM need on the motherboard?
The module is a 288-pin DDR4 RDIMM and requires a matching 288-pin DDR4 DIMM slot that supports registered ECC memory.
Which way round does the 64GB DDR4 3200 module go in?
Align the single key notch on the module with the slot key, press straight down until both side clips click, and confirm the 2Rx4 label faces the same way as other installed modules.
How can I tell if the 1.20V ECC RDIMM is starting to fail?
Watch for corrected ECC error counts rising in the system event log or IPMI; a growing count means the module should be swapped before uncorrectable errors appear.
