With Hyperthread=1 and ThreadCount > Physical CoreCount, Prime95 is giving an error statement of:

Cannot initialize FFT code, errorcode 1010
Unknown gwnum error code: 1010

Either option is to set Hyperthread=0 or reduce the threadcount.

For full system stress (power, thermal and stability), hyperthread=1 and ThreadCount=PhysicalCoreCount is an optimum solution.

When you are running on a system without hyperthreading, how much stress does it put?

When you are running on a system without hyperthreading, how much stress does it put?

If hyperthreading=0, threads=physicalCoreCount, stress is approx 50%
If hyperthreading=0, threads>=logicalCores, stress is approx 75-80%.

Full system stress (~100%) is coming up with hypertheading=1, and threads=physicalCoreCount
