I just got WCG running on an old PIII 833mhz. 256mb box, using Linux libranet 2.8.1 It all runs fine, what I am finding is that when it is crunching the numbers, the fan goes into (what seems) a higher mode (its a lot louder). Is this to be expected, from an older machine, also will this do any damage to the system.?

Hello carpinus,
Your fan speeds up because your CPU is running at maximum utilization, increasing its heat output. Is this dangerous? Depends. There are a lot of threads about clearing dust out of systems and heat sinks. Start off by looking for a CPU temperature monitor: http://www.worldcommunitygrid.org/forums/wcg/viewthread?thread=5248 mycrofth |

The fan is running because this project is designed to drive the computer at 100% unless throttling is engaged.
----------------------------------------Old? There's a pentium III 500MHz running Rosetta here that's not complaining. You might look in there and clean out any dust. Another idea would be to get an ADDITIONAL case fan if there's a spot for one. (in addition to the large one in the power supply) They are made in different sizes, so look at the distance between 4 corner mounting holes. They are cheap -- $5 to $10. I put a chassis fan on a new computer here and it dropped the temperature another 8 degrees. This particular motherboard has 3 tiny sockets for the CPU fan (look where the cord goes), chassis 1 fan, and chassis 2 fan, which will be the same socket size.

I have a P3 667MHz with a 3rd party heatsink/fan but no additional case cooling. It runs as a server but with grid apps for idle usage. It frequently manages many months of uptime without a problem, and I've had that system since 1999.

Hehe we should start a thred called "slowest cruncher!" :) I have a couple P2's running NOTHING BUT BOINC on debian :) I think one is a 400mhz and a 600mhz :) they just sit in a corner with 6 dedicated WCG boxes
 most of them don't even have covers on them and are prolly full of dust but I haven't had any problems with them going down. |

Hehe we should start a thred called "slowest cruncher!" 400MHz is probably about borderline. I recently took a Pentium II/400MHz offline for other reasons. While it was active, two of the longest Rosettas it had crunched were 315 and 325 hours, over 13 days each. That's getting very close to the two week timeout of 336 hours.

Well considering that it doesn't do ANYTHING but WCG I think it should be all right, I'm sure it's border line but I figure since it doesn't do ANYTHING other than WCG (it would be in the garbage otherwise) it can just do its thing, if it happens to time out on a work unit so be it, it will try again on another one, I'd rather have it finish every other unit than not finish any units. And I watch my devices almost daily to make sure they are keeping up with reporting, thats how I tell if one went down or not :)

I have 19 old PIII's from 450MHz to 550MHz happily crunching away on UD agents. I've had some fairly long crunch times, too, certainly well in excess of 200 hours but the end results all go in the same bin as those from the faster folks.
I notice that my hard-earned position at #80 (on points) has required about 14 years computing time from me, whereas others who have achieved the same number of points have done so with less than 7 years. The trick I find is to adopt a mental attitude whereby you can regard these old machines as hi-tech fan heaters helping to keep you warm and cosy!! Happy New Year to crunchers old and new. David. |

About borderline, I just saw that my Old P200 MMX (
) which is used as a router, can't do proper WCG operations.About 0.02% with 3 hours, which brings us about 625 hours per unit :( (192 RAM) Too bad, I'll use other wcg boxes  |

I just retired a PII 400 - slowest cruncher now is a P4 1.8 ;)
