Anyone know if that “Device Memory 42.7 GB” is fixed or can be increased?

The MacBook Pro M1 Max can be ordered with either 32 GB or 64 GB of unified memory. The geekbench report shows 64 GB of memory (maxed), not sure why only 42.7 GB is usable by OpenCL--so I guess we have to assume that's the max, unless there's some software fix to get it up to 64 GB.

I very much doubt that this would even be possible. The OS and other on-chip devices require dedicated memory as well and need to reserve address space.

You simply cannot max out physical RAM with a single device in a UMA configuration.

It reports the currently free memory as device memory.
