64GB DDR4 LRDIMM for servers
This 64GB DDR4 3200 module uses a 288-pin LRDIMM form factor and quad-rank 4Rx4 organisation. It targets server platforms that require high-density memory in a single slot. The CL22 latency rating matches the PC4-25600 speed grade.
Upgrading from lower-density RDIMMs
Replacing standard RDIMMs with this LRDIMM raises per-slot capacity without adding modules. The jump is worthwhile when the motherboard supports load-reduced DIMMs and the memory controller can address four ranks per channel. Systems limited to one or two ranks per slot cannot use this module.
Installation notes and common issues
Align the 288-pin edge connector with the DDR4 slot key and press until the retention clips engage. No heat spreader is fitted, so airflow across the PCB is the only cooling. The most frequent problem is a BIOS that does not recognise quad-rank LRDIMMs, resulting in no POST or reduced reported capacity.

Questions about this item
What 288-pin DDR4 slot does this LRDIMM module fit?
The module uses a standard 288-pin DDR4 LRDIMM form factor and installs in any server DIMM slot keyed for DDR4 3200 memory.
How is the quad-rank 4Rx4 LRDIMM seated, and what step is often missed?
Align the notch with the slot key, press firmly until both ejector clips click, then verify the BIOS detects 64 GB at 3200 MHz CL22.
When should this 64 GB DDR4 module be replaced?
Replace the stick if memory diagnostics report uncorrectable ECC errors or the system fails to POST with this module seated alone.
