How do I stop Bonic using 100% of my cpu so that bonic doesnt fry my cpu?
I have changed my preferences but it still doent stop using 100%.
Is there anyone preference that controls this?

It uses the lowest priorty. 100% is the way it is supposed to work. Classic did the same. I have had computers running 100% for a few years, and none have fried.

Leave it alone, it works just fine.

Cheers. Hopefully that damm CPU beeping stops.

If there is beeping it's the BIOS.
Check what the CPU temperature is. If it's high then you need to fix the problem, not the sympton.

If it's a temperature problem, I find that opening the case and pointing a fan inside is a cheap and easy way to fix it.

Yep, but it's always nice to fix the actual problem.

The chip is designed to run 100%, 24/7, for years. If it's overheating, then it's an overheating problem, not an overworked CPU problem. The most likely culprit is inadequate airflow. Something as simple as opening the case and using some canned air to knock the dust off may be all it takes.

There are programs that work with the OS to limit the amount of CPU time any one process gets (for some reason the name "Threadmaster" comes to mind), but I have absolutely no experience with them so can't comment any further, other than I've heard they exist.
If you think education is expensive, try ignorance.

I've hear CPU run at 100% all the time.. doing the whole idle processes. Well, I've run my PC 100% 27/4 since the PIII came out... if you dont overclock, then your fine.

Not necessarily. True that when you use the CPU in a normal way that the stock fan will be able to run it, but as soon as you start running it 24/7/365 with only the odd reboot, you may want to check for a better CPU fan and/or case fans or another cooling solution.

The Intel P4 (EE) with HT and most AMD CPUs won't make it at the stock CPU. You really do want better!

Actually, you don't.
The stock cooler is more than sufficient for any system running 24/7 that isn't over clocked. A better fan or heatsink is only needed if you wish to overclock.
This is of course assuming you haven't shoved the case under a desk & hard up against a wall on long shag pile carpet & buried it under a pile of rubbish.

Actually for some cpu's you do, if you push them hard i.e. at 100%, early AMD XP's, with stock cooler would easily run in mid 60C's with cool ambient doing nothing. And with our 2000+ we bought new case, ThermalTake Xaser3 (7 case fans), and Zalman HS/Fan which help's but hasn't fixed problem.

And my son's early P4 HT 3.0 used to indicate overheat if ambient went over 25C until we change the HS/fan, although I do suspect that is a BIOS problem reporting temp higher than it actually is.

All just indicates problems with the way the system has been set up to me.
The original Athlons ran much hotter than the early AthlonXPs & i had no problems with either with the stock cooler inside a system with it's covers on where the ambients were as high as 37°c.


BTW- mutliple case fans often make things worse as the CPU fan is unable to draw in enough air. Just pulling one side of the case off will drop the CPU temperature by around 5°c without even using a fan to blow in to it.

At one stage the AthlonXP was run with new HS/fan outside the case in a cool room, probably 20C or lower, and running seti still ran hot at 65C. And have tried all options of fans on/off, side panel off. That cpu runs hot, when trying to diagnose problem you will not try a second time to grab HS until its been off for at least 5 mins.

For info, I'm an electronics engineer with over 40 years experience, try cooling 10KW class A (max theoretical efficiency 35%) amplifiers.

Odd in the extreme.
As i mentioned earlier, the stock heatsink & fan are more than sufficient for cooling the CPU in ambients of 37°c.

Only time i've come across CPUs actually that hot (or hotter) is when overclocking- the core voltage has been bumped up significantly.

I recently installed threadmaster, one word.
search it on net and you will find it easily.

Use the install.cmd, winxp only - read their homepage, not a win 98 thing,,, tried. :)

then edit with regedit as it says in the readme.
then post a question for threadmaster and I'm sure you will get help if needed.

It is not super clear, but it is small and easy.

Cheers. (setting here is 85%, but Boinc.exe I made no special entry for. So it shall run at the default 15% as you will soon read.)
