DIMM,64GB PC4-3200AA-R,4Gx4

HPE P11446-1A1 is a 64GB server memory module for systems that support its memory type. Its DDR4-3200AA rating identifies the memory generation and speed class, while PC4-25600 is another designation for that speed tier.

The module uses a dual-rank 2Rx4 ECC registered RDIMM design. ECC provides error checking, and registered DIMM is the module type; these characteristics make it a server memory option rather than a general-purpose unbuffered DIMM. The server platform must support DDR4 registered memory for this module to be suitable. The listing identifies it as a single 64GB DIMM, useful when adding memory capacity to a compatible server.
