Inspiron Buzzing Solution

Thread Starter 
I, like many others, have the loud high pitched buzzing problem whenever my computer is idling. It was driving me insane. I've tried the USB Power management fix, but it didn't work at all. Actually, i think it made it even louder. So I finally found something that gets rid of the noise.

Download RMClock 2.05 and under the Management tab, enable "Run HLT command when OS is idle" (under Management Settings). Make sure you uncheck/disable "Use OS load-management". Since the HLT process will now take control of your idling process, Windows is going to think that you are constantly at 100% load. Thus, SpeedStep will always set your CPU at Max Speed. By disabling OS load management and using RMClock to control your "Performance On Demand / SpeedStep" settings, your CPU will clock up/down when it is appropriate.



You will notice that your idle temperature is slightly higher. This is normal and is because the CPU is no longer allowed to drop down in the Deep Sleep mode (C3/C4 states). Plugging in a USB thumbdrive will have the same effect (a power management bug in Windows XP). This is basically the only way (short of replacing your motherboard) to get rid of the buzzing.

Regain your sanity and enjoy!

EDIT: UPDATED FOR LATEST RMCLOCK VERSION

I tried it and it works. I don't have the noise anymore but my CPU load get up and still at 100%. My CPU begin to heat and my fans start spinning at full speed !

Someone have a tip for my CPU load problem ?

Well ithe cpu is not really at full load. You unchecked OS Management right? If you look at RMclock again, you see that the CPU load is lower, even though windows tells you OS load is higher. Mine only goes up 1-2C, and that's it.

I enabled the P-State Transitions with 8 different steps and watched the CPU load and temps at different loads of my CPU and it is ok now.

Thank you for the solution !

so what is the buzzing noise? and what does the "Run HLT command when OS is idle" actually do?

The HLT command is a simple instruction that tells the CPU to 'sleep'. This way, it consumes less power and hence generate less heat.
Not my words.

For me its only really constant if i have teamspeak open and no sounds playing anywhere.

HLT command basically tells CPU to sleep and be idle, thus generate less heat and use less energy. It is already implemented with the NT core, Windows XP uses this instruction.

Give it a try and see if it works for you
Does this work for the XPS2?

I have a high pitch noise that I can't seem to target.....

Just to clarify this isn't the video card buzz we are talking about but the buzz that people seem to be hearing that appears to come from the right fan?

There's a million types of buzzing. If this doesnt fix it, then the buzz that you have is obviously not the one that we have.

HLT: HaLT? It's just my guess of what it could stand for.
