Physical memory

Represents a physical memory entry, providing its capacity, clock speed, and available registry metadata

Original source

The macOS physical memory information are provided by MacOsPhysicalMemory, which inherits PhysicalMemory

KInfo's source

val physicalMemory: List<PhysicalMemory> = hardware.globalMemory.physicalMemory
val sample: PhysicalMemory = physicalMemory.first()

The examples require a non-empty physical memory list; check it before calling first(). On Apple Silicon, a single entry describes the unified memory when the required registry entry is available. Unavailable textual metadata can be unknown or empty

Properties

bankLabel

The memory bank label. The Apple Silicon unified memory entry uses unknown

val bankLabel: String = sample.bankLabel

println(bankLabel) // unknown

capacity

The capacity of the memory entry in bytes

val capacity: Long = sample.capacity

println(capacity) // e.g. 17179869184

clockSpeed

The memory clock speed in MHz, or 0 when unavailable

val clockSpeed: Long = sample.clockSpeed

println(clockSpeed) // e.g. 0 when unavailable

manufacturer

The memory manufacturer reported by the native registry

val manufacturer: String = sample.manufacturer

println(manufacturer) // e.g. unknown

memoryType

The memory type reported by the native registry

val memoryType: String = sample.memoryType

println(memoryType) // e.g. LPDDR4X

partNumber

The memory part number reported by the native registry

val partNumber: String = sample.partNumber

println(partNumber) // e.g. unknown

serialNumber

The memory serial number reported by the native registry

val serialNumber: String = sample.serialNumber

println(serialNumber) // e.g. unknown
