eah we know about all those :P They are pretty much the required things for working with dells, other than a lot of patience and a strong urge to not kill yourself when they break all the time.
For RMclock your cpu HAS to be supported and since demitri hasn't been working on it since I've been on those forums, that means only laptops with cpus and chipsets pre-early2008 will work.
For RMClock, be sure you downloaded word for word, RMCLOCK UTILITY beta 2.2 (RC3), or 2.35 (I use 2.2, it seemed to work better)
Then for relief play around with it. :P
You can do it without running the HLT command, but if you absolutely must, you can use that as a last resort, and it SHOULD kill the ringing sound by putting the cpu under some load all the time.
HLT command works well, but it's a bit annoying to work with. The cpu power it uses will be freed up upon using a program, but your temperatures will be higher than usual, by a couple degreesish. HLT command is found in the management tab.
The ringing is actually caused by a bad resonance at around 18khz, our upper limit of hearing. In order to push this resonance higher you need to kick the cpu out of wanting to go into low power mode, change the voltage / frequency it uses at low power mode, or what I do, all of the above and all that I have listed. Completely works.
That can be solved by the following;
-Keep the cpu ACTIVE even a teeny bit! Best way is to have the usb hub on all the time
- Change system power settings over to rmclock's control, and change the preformance in rmclock to always on.
- Prevent the cpu from going into low power mode by disabling the pop-down / pop-up controls, and disable c4e c5e sleep states (they are the ones that cause the issue)
-Change some of the voltages by about 0.025V, I found that to be the best spots, but the upper ones should be fine, what I have listed is for undervolting, but it seems to work great for the whine as well.
Make sure your cpu is SUPPORTED if you see a crap load of stuff blanked out, it's either not activated, not correctly installed or not supported. Theres a few ways to force it to activate through the registry, but only a couple settings will work if your cpu isn't supported. message here OR on RMclock's forum if there's issues.
My settings are here. Thats after unlocking everything and a LOT of tinkering.
Please note that this worked for me and all testing was done under a pentium 3, C2D and Core Duo platforms that had mild to severe whine (C2D the worst)
But for a quick fix, I know that HLT command works, and amazingly well. My settings avoid increasing cpu temps and will stop the cpu from dropping into its "enhanced/annoying" mode. It might nessicarily not work for you though, so if it doesn't work again, HLT command all the way, a few degrees matters to me, but to you it's probably nothing compared to sweet ear release. (Just keeps the cpu under some load)
