Posted 27 Feb 2009 by Napsterbater Post: It's more like multithreading on a single core ;) Ok i have a Tri core AMD phenom II x3 720 with an ATI 4870, I was testing some setting and set the "avg_ncpus" to .1, and restarted boinc what I saw with I got 3 MW WUs running and 3 Seti WUs running (2 using 100% of 2 cores 1 use maybe 66%ish), now my questing is do these WU need a 100% of a core to do the same work or can they use 33%ish (all 3 combined) and get the same work done. What I'm trying to say in theory would allowing another project to rune like that produce that same amount of credits/hr for WM, then not running the other project. Just trying to get the most out of my computer. EDIT:To add If I leave "avg_ncpus" set to .5 Boinc only runs 2 Seti (100%x2) and 2 MW at 50% each (100% of one core), and .1 get 3xSeti 2x100% 1x66% and 3 MW's using a total of 33% of one core. |

Posted 27 Feb 2009 by Napsterbater Post: If i was you i would see if i could improve the cooling in your computer a bit. This computer is a 4u Server case with a 120MM fan on the left side (in front of the vid card) plus a 80mm delta (lots of air and very loud =P) behind the 2 3.5 slots. plus a 80mm Delta directing air from just in front of the card down it towards the back of the case.
kinda though that might be it after posting, but thanks for confirming it. |

Posted 26 Feb 2009 by Napsterbater Post: humm, idle is about 46°C, were you crunching or idling at when you took those readings? BTW I'm at 100% Fan speed and overclocked to 800/1000. |

Posted 26 Feb 2009 by Napsterbater Post: Just attached and installed the .19b on my system that has a Sapphire HD4870 1gig, and only issue I have is the screen stops for about 2 seconds every 10-60+secs, anyway to fix that? Also what everyone Temps on their cards I'm at 83-88°C. |
