Is it possible to "Underclock" a CPU?

post #1 of 16
Thread Starter 
Not that I want to, I am just wondering. Like would it be possible to run a 965 BE at 1.6GHz?
post #2 of 16
I can run my E5300 @ 1.2Ghz.. stock speed is 2.6Ghz.

Yeah, if you want. Technologies like Intel Speedstep and AMD Cool n Quiet do similar things, and clock down/underclock the processor when the user isn't performing intensive tasks, cutting down on heat output and power consumption.

yep, it can significantly cut down on heat and power consumption. Some people underclock laptops to get better battery life and so they dont run extremely hot

+1 to that.

Just let the CPU run on stock with all the power saving options like C1E and EIST

Yeah. I've got my laptop CPU underclocked and undervolted. Battery life has been increased as a result of the underclock/volt and the fan runs less because of less heat being generated which means the fan doesn't need to run as much meaning battery life is increased that way as well.

On my linux netbook I used a user space cpu frequency module to lock it at the 1000 MHz minimum speedstep The difference in battery life was small as the on demand module spends most of it's time at the lowest anyway. I think you can set a max CPU percentage in w7 too.

ohh its possible....i have a i7 930 suppose to be 2.8ghz..but I got it as low as 1.2ghz.. It probably will go lower but the setting in the bios will not allow it.
