Prime95 should not do that -- I believe it should tell the OS to run the 3 threads on any core. When starting prime95 does it tell you which logical CPUs it is assigning threads to?

You can try setting "Affinity=1,2,3" in the [Worker #1] section of local.txt. That might help.

If still having trouble, run a benchmark (abort it anytime) and send me the hwloc topology written to either results.txt or results.bench.txt. Also send prime.txt and local.txt.

Good luck
