I recently came across an Intel pentium 4 3.0GHZ Processor w/ HT technology. When I install it in my computer, The machine recognized it as a 3 GHZ processor but shows it running at 1.5 GHZ. I downloaded SPEEDFAN to see what my temps were running and it showed CPU0 and CPU1 and listed them as two CPU's. Can some one clear up the confusion by telling me how a single core processor is listed as two and why doesn't my processor run at the 3GHZ speed and only runs at half that...???
