Speed 5600MHz

  • 64 GB capacity expands server memory headroom for large workloads
  • DDR5 5600 speed delivers high bandwidth for data-intensive applications
  • ECC registered design detects and corrects errors to protect data integrity
  • 4Rx4 organisation maximises density within a single 288-pin module
  • 1 V operation reduces power draw in Dell PowerEdge XE9685L systems

64GB DDR5 5600 ECC RDIMM

This 64GB DDR5 5600 CL46 registered DIMM adds ECC capacity to the Dell PowerEdge XE9685L rack server. It runs at 1.1V with a 4Rx4 organisation and uses major OEM DRAM from Samsung, Micron or Hynix. The module fits standard 288-pin DDR5 slots and requires no heat spreader for operation.

Upgrade from lower-capacity or slower DDR5 modules

Replacing smaller RDIMMs with this 64GB stick increases total memory bandwidth and rank density per channel. The jump is worthwhile when workloads such as virtualisation, in-memory databases or large dataset processing exceed the current installed capacity and the platform supports 4Rx4 registered modules at 5600 MT/s.

DDR5 RDIMM platform limits

Registered DDR5 modules rely on the memory controller to manage on-die ECC and command-address parity, so the server BIOS and CPU must qualify 4Rx4 parts at the rated speed. If the platform caps memory frequency below 5600 MT/s or restricts rank-per-channel population, the module will downclock or may not be recognised.

Questions about this item

Does the 288-pin DDR5 RDIMM fit the Dell PowerEdge XE9685L memory slots?

Yes, the 288-pin DDR5 RDIMM form factor matches the slots in the Dell PowerEdge XE9685L rack server.

How do I install this ECC registered module correctly?

Power down the server, open the chassis, align the module key with the slot notch, press firmly until both retention clips click, then verify the 64GB capacity in BIOS.

When should I plan to replace this 64GB DDR5 5600 module?

Replace the module if memory diagnostics report uncorrectable ECC errors, the server fails POST with the DIMM installed, or a firmware update explicitly requires a newer revision.
