my pc is working 24 hours a day and i need a software that can underclock the prossesor from 00:00 to 08:00.
cpu : E5700 3.0 Ghz (3.5 OC)
windows 7 Enterprise.
note : Intel speedstep technology is enabeld but i need to reduce the bus as well.
The speedstepping should down clock the CPU during idle, But you can always use the profiles in the bios, like set 1 profile to say 3gh and the other to 3.5ghz, You will have to restart but thats only why I would know of on an Intel dual core system.
