Ryzen 3900x - only half of threads being used?

See picture for reference. macos does correctly identify the 24 cores of the CPU (it has 12 cores, double the threads) but the odd threads are never used. Did I miss a thing in setting up my hackintosh, or is this expected behaviour on a AMD hackintosh?

In Windows, all threads are actively used, so apparently it's not a BIOS setting.
