Dell 640m/1405

Hi All,

I just bought a new 640m/1405. So far I love it, however there is one thing that is troubling me.

I ran CPU-Z to get the CPU details and it only is reporting the Core Speed at 998.7 MHZ. I configured my 640m with a Core 2 T5600, so it should be at 1.83. I thought it might be the Intel Speedstep thing, so I disabled it in the bios and I still get the same thing. Very strange, happens when I'm plugged in or on battery.

I also have a IBM T60 and it is the 1st gen dual core, (T2400 @ 1.83.) It reads the Core Speed at 1.83 all the time, plugged in or not.

Any thoughts on this would be appreciated!

Thanks.

 

Maybe the settings didn't save in the BIOS. My 6400/1505 usually reads just under 1GHz or 1.32GHz but jumps back up to 2GHz whenever its needed. I'd just turn speedstep back on and not pay attention to it. To test it you could install I8kfangui and run a game with it open, play the game for a while, then go look at the graph in I8kfangui and see if the clockspeed changes.

 

go to power settings in control panel vhange them from portable to always on this will lock cpo its just speedstep adjusting cpu power versus load
