Perhaps later releases of linpack will become multithreaded. Until then you can run prime in background to fully load all 8 threads, and cause full vdroop so you can check stability, and then run linx at same time. This is no harder on your cpu than running either prime full load itself, or running linx itself with hyperthreading off. It takes linx longer to run, but that way you still get increased efficiency of linx.
For example at 2 notches below stable, prime v25.8 latest, takes about 2-3 hours to error or reboot. With prime running, then running linx, linx will error within 3-5 runs, much faster. But like you have noticed, since linx/linpack will only load 50%, it does not cause full vdroop, and hence I can run linx all day by itself at 2 notches below stable because vcore is much higher from lack of vdroop of full load.
Hopefully intel will come out with multithreaded version as some point.
