Dell optiplex 745
Intel core 2 duo e6600 2.40ghz
windows vista business
4gb samsung pc2-5300 (333mhz) ram
160gb h/d
ati radeon x1300 pro PCIe 256mb dvi
when I ran cpu-z v1.4 the core speed is showing 1594.9mhz ,multiplier x6.0, bus speed 265.8mhz, rated fsb 1063.2mhz.
So my question is why does the cpu appear to be running below 2.4ghz?? how can i correct this?
