Default Re: Hyper Threading problem

This is indeed normal - windows is not aware of there being one CPU with HT - it thinks you have two precessors. Therefore when you run an app it will assign the full processor power to it, but because of its HT it still has another pipeline free to use on another app. Hence windows will only see one processor working and the other at zero. To get both to appear to run try running two instance of a program like folding at home with different machine id's in command line mode - it certainly does it for mine! another technique I found to fill up the CPU usage on both processors is to RAR two or three or more largish files at the same time, thus making use of the HT support and making both processors in task manager 100% workload.

Yeah, its all pretty simple when you get the hang of working out what is best where.
