Cpu Core Speed Self Adjusting...

Question

Hey guys, i am a long time dell owner (laptops and desktops) and just recently found this forum. I now currently have an Xps M1330 w/ T7500. i had this problem on my M1210 when i had it, and i solved it somehow but i cant remember...well its not necessarily a problem. I am to assume that our dual core processors dynamically switch; they dont always stay at the same core speed. this is something i DO NOT want. i find sometimes it does not adjust (when playing games) or keeps adjusting (goes from 1.2 to 2.2 and then back down to 1.2 immediatly). anyways i have found there to be some lag with this process. i used NHC and monitored with CPU-Z on my core speed. with the adaptor plugged in the core speed self adjusts according to the situation; going anywhere from 1.1ghz to 2.2ghz, and on battery power it is steady 1.5Ghz. i want to keep my core speed steady at 2.2ghz at anytime while the adaptor is plugged in to receive maximum power. How can i accomplish this? Thanks

Set the power scheme (control panel) to Always On. Bear in mind however, that the system is not designed to cope with the heat of running at full speed all the time, so you will see a reduction of life in the internal components of the system by doing so - the hard drive, mainboard, video chip and RAM will all see reduced lifespans.

Thanks, however i am using Vista and there is no option for that.  i have it set to High Performance although it does not keep the core speed locked at 2.2ghz

There is an advanced setting link on the power options page. Click it and you can adjust many power saving options. I guess even in high performance the setting of CPU speed is adjusted to min=5% and max=5%. I use balanced and it is like that. It is the same for power saver as well. You might adjust the min=100% and maybe have full speed CPU all the time. I haven't tried it and won't be doing as I fear things might get too hot!

@IS that true of ANY notebook? I'm toying with getting an XPS 1730 today, and I want to run Folding @ Home on both cores 100% of the time it's on. I'm hoping the larger design of the 1730 (which appears to be built to be used and handle heat) can handle it.

disable SpeedStep in BIOS. press F2 when u see the Dell logo. go to Performance, select SpeedStep and disable it.

tigerwolf7 · Answer

That dosen't default it to it's LOW speed does it?  I though I read that somewhere.

tigerwolf7 · Answer

Yeah, but I think there were people talking about how disabling it in the BIOS actually defaulted it to the LOWEST speed it could do rather than the highest-that it had to be on to hit the max clock speed.

But I don't know what systems that was or what clock speed. To me I'd MUCH rather have the ability to shut it off and have the default it to the highest speed.

mike4realz · Answer

low speed? not sure where u heard it from but speedstep is a power saving feature that dynamically adjusts the clock speed, voltage, fsb to match the performance of the applications being used. if disabled, the cpu will use the default clock speed (T7500 - 2.2ghz).

Bump, anyone have an answer? i've been gaming and when the CPU clocks down i get some annoying lag until it goes to full power again...it gets really annoying.

would turning dynamic acceleration off in the system BIOS be the answer?

brown_fv  The best way I know of to stop it from doing that is to set your power options to always on or max performance.
