That's working as expected. The CPU can't hit the top turbo speed when using all four cores. Also, Prime95 is so efficiently coded that using hyperthreads (which is basically two threads taking turns on the core) doesn't speed things up.

With regards to only one worker, I believe it will force that if you're working on very large exponents.

Is there a standardization for prime.txt ? I'll send my machine through it.

Hello.

As a brand shiny new noob, should I run the benchmarks non-HT and single core for best and most useful results?

In Prime95 <options><benchmark> and let it run for a couple of minutes. Copy the output from results.txt to the link provided above.
