RM Clock and The Buzzing.

So I read a bunch of posts about the high pitched noise. Never heard it before but now that I read it, there it is. If I never read it I would have thought it was just normal. Great.
So now I have install RM Clock to fix it. What exactly does checking that box do to the computer. The CPU and Voltage graphs are off the charts. Is this good bad? Will this hurt the battery? I am usually at a desk and let the battery run out or close to it and then plug it in. So I don't really care about battery life but I do want to save it for when I do.
So.. all help is appreciated.
thanks

 

It prevents the CPU from going into a lower state of sleep, so by not being able to do that it appears to solve the noise but ur CPU doesnt slow down when not in use.

 

Does this harm or overwork the computer?

 

no it just means that when for example you are on battery power, the CPU cant use its full power saving abilities to prolong your battery life. in other words expect your battery time to drop.

 

I noticed when I turned it on with RM Clock, the sound immediately went away, but Aero was NOTICABLY slower

 

Thats interesting. I hope this is fixed soon, I haven't received my vista upgrade yet and don't expect it for a little while. But it should give them a chance to fix it. I heard that it is a large problem for many brands and is more a core duo problems then anything, so maybe there is no fix. Who knows, but I definetly don't want to return it or lag the power and abilities.

 

Is it supposed to keep the fan running constantly and raise the temp? Mine went from about high 30s to mid 40s.

 

yep. its almost acts like its really doing some work. open up the task manager and you'll see cpu usage is through the roof on rmclock.

i dont like this method at all.

 

I found this problem to be so ridiculous I returned mine.

 

lol, i heard. Seems like you couldnt wait to get rid of it, i saw your other threads.

 

=D I know, it was driving me mad.

 

From what I read it seems to me you guys use the "Run HLT command when OS is idle" option from RMClock, right?
If so: Don't.

Instead: Go to the "Advanced CPU Settings" tab, enable all (or not all, not sure bout that cos I didn't see no differences in heat/load/watt) C-states, then go to the "Platform" sub-tab and uncheck "Enable Popup Mode".

The C2D noise goes away and it'll consume a lot less energy than the HLT command version (which simply makes RMClock use up all unused cpu cycles in order to keep the cpu busy). For instance, on my NC6400, activating the HLT option costs me a little over 1 hour of battery juice. The no-popup version costs some 20 minutes. Besides, the cpu doesn't heat up and so the fan doesn't start (and thus consume even more energy).

What that popup/down thing does (AFAIK!) is stop the cpu from constantly switching tween the C3 and C4 modes while the OS is idling - and that seems to be the reason for the whining or buzzing or whatever you want to call that noise.

can someone explain exactly what C3 and C4 is/does? and if we want it to stop switching between the two, shouldnt the latest firmware be able to stop the buzzing with its new disable C4 feature?

What will disabling C4 do exactly, and what effects will it have?

 

I do not understand all the fuss about RMClock. I didn't need it at all!

In the 'Device Manager" ("Start", right click "My Computer", "Properties", tab "Hardware"), open "Universal Serial Bus controllers", open the last "USB Root Hub", click on "Power Management" and unselect the option of "Allow the computer to turn of this device to save power". That's all. I read it somewhere, didn't find it out myself.

Acid, just read it didn't work for you, sorry about that. For me it worked only when I deselected the last USB Root Hub, not the others - guess you tried them all.

 

@DV6174CL: That's jus the "fuzz", the USB thing works only for some. Besides, I usualy work a) in an area loud enough for me not to hear the noise or b) while listening to music on my headphones. So all I need is a quick fix for those rather rare occasions where I could actualy hear it. RMClock does just that while not wasting any energy the rest of the times (like - I guess - your USB fix does).

@aphexacid: Not that I'd understand all that engineer talk but:

In (inaccurate and) short: C1 to C4 are different levels of inactivity of the cpu. The less the pc is doing, the deeper the c-state the cpu can fall back to and the less energy it'll consume.
Deactivating C4 (where possible, e.g. the Bios update for the NC6400 did sadly not include that option) will simply limit the cpu to C1, C2 and C3 and that means, it'll consume a bit more energy than it would if C4 was available too. It will not make the cpu slower and it will (most definitelly) not make it run hotter while idle. It SHOULD fix the noise thouhg. But, why don't you just try?

 

I think i'm gonna take a crack at it. The only thing about the new bios that i dont know how much i like is that it does something to the fans. i dont mind hearing the fan, or the fact that its spins at higher rpms. i'd rather it stay cool than be quieter. but i guess i'll need to see for myself, i can always flash back to F12 if F15 is not to my liking.

i think i'll give it a spin right now actually...

 

Let us know how it goes for you.

I have a Vostro 1500 and also have this problem.

I've unchecked the Popup and popdown modes and the buzzing went away.

But now I have a question, if these modes are used to switch between states, this means that when they are disabled the CPU will stick to a state and never change?

 

uninstall rmclock... it's not stable... nor fully vista compatible

 

WRONG! The newest version IS Vista compatible and I have been using it since I bought my new HP laptop and never had ANY problems.

 

can you show me how to uninstall rmclock? it couldnt find it in "Uninstall or change program"
