I hear the sound as well and actually just came to start a post.  It seem to be near the fan or just behind that.  Its an extremely high pitch squealing that is steady but breaks up with hard disk access.

 

Dell Aaron advise if you can!!!

 

It is annoying although not to the point that I want to call in service yet.  Glad I got the 3yr NBD now.

 

Exactly this i hear too.

Some solution?

 

My Mainboard was switched 3 times now. All have the same problem.

My configuration is the same, only HDD is the 120GB 5400rpm/U.

 

My ears squeezes me up this time.

If more users have this problem: POST!

I know this programm can u say to me which exactly settings in RMClock u´re using?

I have the exact same issue, a high pitched whine, however, it only happens when the processor is at IDLE only. It can be done to cause the processor to be under a constant load and for that load to be alleviated when need be. A utility called RMClock allows this to be done to the processor. I used it and the whining sound is gone completely. By Running the HLT command and telling the program to autostart, it allows this to happen through its management tab. Hope this helps, worked for me.

I know, the noise is freaking annoying and supposedly!!!!! it has to do with throttling down to a ghz when its idling, which is fine and dandy, just the noise is a killer. I have RUN HLT COMMAND WHEN OS IS IDLE on, no you don't REALLY need it on autostart, but it is a good way to not have the sound ever bother you. I've also configured my duals to have the maximumed allowed voltage (thats controlled via bios) and throttling not active so my core clock is degraded still but the actual throttle is set to 2.33Ghz. Anything with load i found helps, however, dell should really be helping you guys out, ive had eight problems from the screen not turning off correctly when i close the lid to this and pixel problems and video issues and ive managed to patch it all up to work, but man my registry is a mess now.

I would be curious how you tweaked your cpu's with this utility as we all have similar processors and you definitely have the knowledge, as well.  I have downloaded and installed RMClockc Ver 2.2.

 

Do I need to have it autostart and run minimized in the sys tray in order for it to work each time i reboot; I have HLT enabled.  Could I not just click HLT, NOT autostart and minimize it and then NOT return the CPU to its former state on management and application exit (uncheck these boxes)??

 

Help has been and will be appreciated here...that noise was getting annoying; it is still annoying that I have to correct an error in a 2500 laptop I have only had  months.

 

PS I would still LIKE DELL TO PROVIDE SOME ASSISTANCE HERE IF I MAY. LETS SEE OUR CUST SUPPORT SINCE YOU DO MONITOR EACH AND EVERY POST.

 

 

You and I sound like twins...  I have enjoyed this project, for the most part, having overcome difficulties with Vista RC2 to include sleep/hibernate modes, video and so on.  My system still will not sleep unless it is on battery power alone.

 

My registry is like a mine field I believe.  On boot, there is a pause of about 20 seconds before the internet confirmsand bluetooth clicks in and now this rmclock program.  Then just when you think its done...quick blank screen while the appropriate 7400 drivers click in. 

 

I WOULD GIVE ANYTHING TO FIX THIS!!!!! I look forward to my Dell upgrade to start everything over and hope it installs properly.
