I´m running a X2 4800+ Dual core. I have set my preferences to 2 CPUs but it only shows 50% in task manager. Also my times are slow i think. About 4 houres with optimized SSE2 0.430 AR. What is wrong. regards Mike With each crime and every kindness we birth our future. |

Your results say that you're using the SSE app, not the SSE2 one. It will dramatically make your times faster if you install the SSE2 one on that machine instead ;) Still, it should use both CPUs if you have your BOINC preferences set up to do so. HTH, Simon.

Have you updated your preferences on your local computer? I.e. Did you go into BOINC Manager, select Projects, select SETI@Home (or any project), then hit the Update button on the left? It should kick in eventually. |

Hi Simon. I´m running the SSE2 version of your ap, but no one has finnished yet. Is this normal that they are only at 50% ???? Mike With each crime and every kindness we birth our future. |

I�m running a X2 4800+ Dual core. Are you crunching 2 work units at a time? If so, 50% per cpu would equal a total of 100%. |

Hi Simon. when the first WUs a ready, make an update, at that time BOINC will use 2 CPUs, i have the same poroblem with my P4 with HT Times ago, the BOINC Manager use some time to recognize this. Greetings from Germany NRW Ulli ![]() ![]() |

@Terry Yes its running two WUs at one time. What makes me wonder is that my CPUs needs over 4 houres for one. My sons XP 64 3200+ needs less than 4 hr. And he has only 512K cache and my toledo 1024 x 2. Mike With each crime and every kindness we birth our future. |

Crunching over night 4 results. Between 4:30 and 4:50 for two. Mike With each crime and every kindness we birth our future. |

@Mike, Windows calculates your computer's processing time by the total of CPUs in your system. If you have two CPUs, then each one at 50% would make a total of 100%, so this is normal. As for why it takes your computer longer even though it's faster - could be a few reasons. My guess is that you have more installed and running on your machine that might steal a few seconds here and there from SETI@Home, such as a real-time AV scanner, real-time Adware scanner, file sharing app, web-based thermometer, or any other gadgets loaded with Windows. Also, if you use your computer more than your son does, this will cause your system to take longer as well. |

I think its caused by my slower RAMs. I only have 512 MB DDR 333 my son have 1 Gig DDR 400 running at 217 Mhz. BTW he has more stuff running in the backround like i have. But thanks anyway. I will buy other Ram package next week, so i´ll see. regards Mike With each crime and every kindness we birth our future. |

Definitely your RAM there Mike - it sounds like you're running single-channel RAM with your X2 - that's holding it back a LOT. If you can manage to grab a second stick of RAM and upgrade it, I believe you will see your times go down to 1/2 or 2/3ds of what they are now. Even dual channel 333 is way quicker than single channel. Of course, dual channel DDR400 would be even better ;o) Regards, Simon. Donate to SETI@Home via PayPal!

Its running in dual channel mode 2 x 256 MB DDR 333. But will buy DDR 400 2 x 512 MB. Mike With each crime and every kindness we birth our future. |

Its running in dual channel mode 2 x 256 MB DDR 333.Just keep in mind Mike that, though 1G of RAM is going to speed your Windows experience up to a degree, simply having more will not speed up your crunching UNLESS you're usually running enough apps and background stuff to consume your current 512M. In other words, if BOINC is the only thing running on your desktop and background services are stopped, 512 is vastly more than BOINC requires. Under those circumstances, 1G will not help you crunch faster. However, as has been said, faster RAM will help you, especially if is high quality RAM with fast timings. If you have the funds, don't go cheap here!! Get a matched pair of sticks from companies like Crucial, Corsair, OCZ, Muskin, PNY or Kingston. Spend more than $100US and look for timings of 2-2-2-5 or 2-3-3-5. It will make a huge cumulative difference on your crunching, I promise. Luck - Without love, breath is just a clock ... ticking.

Thanks Jim. Kingston is my favorite. Mike With each crime and every kindness we birth our future. |

It sounds like you've got everything set up correctly. I'd check if it's an error in the Science App with the work unit itself. In BOINC Manager, on the Tasks tab, there should be 2 WU's with status of "Running". Both of their CPU Time counters should be increasing second by second. If you find one WU that is supposed to be running, but whose CPU Time counter isn't increasing, then highlight it and suspend it by pushing the "Suspend" button on the left. Your CPU usage should go back up to 100%. |

Your sons 217fsb is why hes creaming you. I dont overclock my pcs anymore, but when i used to, it would decrease time per wu by quite a bit. gl |

Looking at your Pcs and their benchmarks makes no sense at all. Are the 3500s the 3200 overclocked?. |

No they are 3500+ original. Only my son overclocked a little. Mike With each crime and every kindness we birth our future. |

Thanks. Explains benchmarks. |
