Which statement is true regarding 32 GB DIMMs?

The statement regarding 32 GB DIMMs being only supported on systems using Xeon W Series CPUs is accurate because these specific CPUs are designed to support higher memory capacities, such as 32 GB DIMMs. The Xeon W Series is part of Intel's professional and workstation-grade product line, which includes architecture that can effectively utilize larger memory modules, thereby enhancing performance for applications requiring significant memory resources.

Other processor models, especially older or consumer-grade CPUs, typically do not support such high-capacity DIMMs, limiting their maximum memory configuration. This makes the support of 32 GB DIMMs exclusive to systems outfitted with the appropriate Xeon W Series processors, which cater to professional use cases, such as high-performance computing or complex data tasks, rather than universal compatibility across all types of systems.
