Hi,
I have a new machine, a laptop Intel i5 core.. Couple of questions: 1. I noticed during the night it goes to sleep (like a person!) even though in the power settings sleep mode is set to 'never'. Any thoughts how this could happen and how I can prevent it? Also, if I look into TThrottle chart, it seems it still runs (the line CPU is there, and not 0%), but it cannot be. 2. Also your i5 laptop runs very hot? I have another laptop like that, and it reached (without tthrottle) 85 C!. This one a bit less but still if I set less than 72 C I do not cruch anything almost...Any suggestions? Thanks |

There's that option on the website profile (not in the client prefs), that can instruct BOINC to stop computing after default 20 minutes of no input at the computer. Stop work after computer is idle for: 20 minutes. Set that to zero if not done already. A BOINC message log entry would tell you if this function is actually active.
----------------------------------------TThrottle does the job for pretty much everyone on Windows. Set the temp ceiling... say 65C, and it will slow BOINC. Not sure, but I've installed TThrottle with admin i.e, right click and select °execute as administrator° or something similar, so it can get at the service. I'd say that 75C is kind of the laptop ceiling for ordinary operation. If there's hardly any crunching at 72C, then that's what it is. A little crunching which us more than nothing. You might though wanna do a dustbunny operation. When the fans run at high speed they suck in lots of crud in a few months. --//-- [Edit 1 times, last edit by Former Member at Sep 28, 2011 5:21:00 PM] |

Hi Sek,
thanks for the reply, anyway is not that one the issue, as the profile was already set at zero for that variable. And at 72 C it is pretty good crunching especially at night, so I am leaving as it is with Tthrottle on. Thanks |

Maybe you need to clear the local prefs to be sure that the web prefs do take effect.and set the Activity menu to °Run Always°.
Sort of misread that 72C was where it became borderline poor. As noted, 75C is fairly save, but maybe not for posterity if any were planned ;-) --//-- |

Are you sure it's not going into hibernation mode rather than just sleep? Different setting. You may also need to check the network card and hard drive is not getting shut down. Might be worth noting that some laptops will downclock and may even stop using cores if either the CPU or other components get too hot.
----------------------------------------Maybe frowned upon WRT runtime credit, but on an i5, which has stepping technology (in fact most processors now do), you can alter the Power Configurations (Vista/W7) so that the system operates at lower frequency; say set it to 1600MHz rather than 2400MHz. This uses less power and allows the system to run cooler and quieter. It improves longevity over tools such as TThrottle, which allows you CPU to keep crunching right up to 65degC before stopping all crunching. If it is regularly going over 65degC (or whatever you specify) then tasks will be starting and stopping a lot (so LAIM would be required). As a general rule of thumb, 50degC is about the max for the system (motherboard and other components), which tend to die long before the CPU. So use Speccy or some other tool to get the system temp as well as the CPU temp. Some Bios's also allow you to set a target CPU temperature, and control fan speed. PS. Don't forget to Vacuum the air ducts/fans, regularly. Good luck, [Edit 1 times, last edit by skgiven at Sep 28, 2011 6:55:28 PM] |

No idea where you got 50C for laptops, skgiven, but my duo has been crunching at over 70C and higher for 5+ years and nothing broke, but the battery, which when on juice and charged is preferably taken out. Not an issue on the previous laptop, nor the one before that and the one before and the one before, which ca 1986 had a slide out flat screen mono-color, which really was a portable desktop, running complex multiday analysis at 100% load, albeit, just 1 thread.Maybe frowned upon WRT runtime credit, but on an i5, which has stepping technology (in fact most processors now do), you can alter the Power Configurations (Vista/W7) so that the system operates at lower frequency; say set it to 1600MHz rather than 2400MHz.

Good luck, As for TThrottle, it does not shut down computing [if you said that]... it filters the cycles and BOINC being agnostic of TThrottle, BOINC needing to be set to 100% itself, simply torquing how much at the fractional second level. The BOINC throttle does not unload the sciences with LAIM off when using it's CPU time %. It would be completely stupid. It simply holds in memory whilst it's in the interrupt cool phase for instance at 50 percent, 1 second on, 1 second pause. BOINC 6.10 does not even unload anymore when Benchmarking with LAIM off. Only when specifying the Idle-Work setting it still does that under 6.10 FAIK, which includes that "While processor usage is less than xx %. --//-- |

Yes - it was not on 'run always' under activity. And I cleared the local preferences.
I agree with Sek, never seen laptops under 65-68 C. And TThrottle does a very good job. Thanks |

In addition to TThrottle I use a laptop cooling pad which helps keep the heat down. Mine has two fans built in and is powered by USB. Cost is about $30 and it works fine for me.
