I'll reply to this thread also.
1. When u have P4 with HT enabled. You would not hit 100% utilisation because this has only one thread. It's only 50% - another 50% idle. 2. About those temperatures. I have very warm room where i have all my equipment. That is 4 computers all. 1 firewall, 1 laptop, 2 desktops. Heat causes a stress for those computers. And boxed solutions do not work for me. Atleast if all systems are stressed. Summer time is the worst. I have few Mb's fried - few gpu's as well. I do know what it is with heat... You only have to build reliable and reasonable cooling for your system within your condition. Very good test bench for CPU is cpuburn-program. I'd like to remind u before testing that it might fry your cpu, if you don't take care. |

This is my suggestion too. You have to limit CPU usage.
I have an overclocked machine that was not designed to run at 100% for 12 hours at a time. I installed the application last night, and when I woke up this morning my motherboard was beeping at me that my CPU was overheating. Please fix this. Thanks. [Otherwise it's a great project and keep up the great work!] |

Ehrm...
just a sidenote here.. When OC'ing stuff - keep cooling in mind :) I realize that in order to keep the most badass OC'ers with the project IBM/UD probably will need to do something about the software - but once more... OC'ing a comp without also tuning the cooling is like driving a tricked out speedster with bicycle brakes - fun while it lasts (But mostly stupid :) Considering all that cash that probably went into the most extreme systems - people should really be able to afford a good cooling solution, be it waterbased or just a good fan... |

1. When u have P4 with HT enabled. You would not hit 100% utilisation because this has only one thread. It's only 50% - another 50% idle. I am running a Socket T P4 with HT oc'ed to 3.8ghz ddr2 running a little over 600mhz ASUS p5gd2 premium ATI R X600 (sadly I missed out on the SLI Board) XP SP2 I would like to devote more than 50% of my cpu to this program, is there anyway possible to do so? I tryed to put this on high priority thinking it was going to be an ez fix no such luck i figuered that would not work but oh well , it seems the program is stuck with only being able to use half of my cpu. This makes me wunder if I were just to build an amd 64 bit or even just a socket A barton 3200 would it be able to devote more cpu % ? I need a reason to buy that new asus 64bit SLI board anyway  |

Hi Sirfox,
Don't worry! Your computer is running as fast as it can, even though Task Manager says 50%. Here is an old thread that tries to explain it at http://www.worldcommunitygrid.org/forums/wcg/viewthread?thread=484 Our program Rosetta is keeping your FPU (floating point processor) full while occasional other threads using integer-only instructions will work their way down the pipeline bypassing the FPU. Your computer really is working 100%.  Lawrence |

I wouldn't worry about exhaustion of resources... CPUs are designed to survive long years of usage. It's true that the temperature might be a problem, but there are dozens of great coolers on the market (thermalright for instance). For start you can just open the case - that should lower your CPU temp by a few degrees.

Some systems have been designed to have optimum airflow patterns and removing the covers will actually reduce the airflow across some components and put the system at more risk of overheating. |

Well, that's absolutely right:
----------------------------------------Some systems have been designed to have optimum airflow patterns and removing the covers will actually reduce the airflow across some components and put the system at more risk of overheating. But mb04 mentioned about having some standard case and in such situations opening case can actually help... Regards, |

Here is one that works! It is called the off switch

Hum.
I think it is not a true question, most of CPU have stock cooler, noisy and not so efficient. In fact Intel and AMD are selling products with a hope : that the computer will not be fully used. But even with this situation, dust, thermal efficiency reduction are acting against thermal dissipation. World computing is a good solution to make people understand that their computers need some care, cleaning CPU from its dust is the first step. Furthermore, heat waves can strike at summer, strongly rising ambient temperatures. |
