Is this normal or do I need to do something like turn off turbo-core? Thanks

It wouldn't be caused by turbo core, that has no effect on how many threads a program can use. It may be that prime 95 has a limit of 4 threads, I remember back when it only did 1 thread and you had to run 2 istances of it on a dual core processor.
you should be able to select the number of torture test threads, just set it to 6
