Pentium 4 640 3.2 acting like a dual core
Hi.
When opening the task manager window, under the "performance tab", the "Cpu Usage History" displays two colomns, as if I had a split core? why is this? Running WinXP (32 bit) professional sp2 on a Pentium 4 640 3.2Mhz cpu (with 64bit support)

Running WinXP (32 bit) professional sp2 on a Pentium 4 640 3.2Mhz cpu (with 64bit support) 640 has Hyperthreading, which is two virtual processors running within one physical processor. Not as effective as two real cores, but suitable for making the desktop run smoother. http://processorfinder.intel.com/det...px?sSpec=SL7Z8 http://en.wikipedia.org/wiki/Hyperthreading Paul
