Hi ! I have started running Seti again after some time away. I have setup a machine with 2 radeon 7990. Been running for a week now and are seeing 35.000 . How much will 2 of these cards produce at peak. Not running CPU. Thanks ! The_Wiizzard |

Hi ! See https://boincstats.com/en/stats/-1/host/detail/284612264/charts. The daily update graph says about 65000. To overcome Heisenbergs: "You can't always get what you want / but if you try sometimes you just might find / you get what you need." -- Rolling Stones |

Hi ! Thanks for the answer. Good page you redirected me too. I'm running 4 instances per per card and has a CPU utilization of near 100%. Is this as it should be. Then if i add another card the CPU couldn't take it !? The_Wiizzard |

Considering you have a 4 core CPU and running 8 instances already which takes approx 50% of a CPU core you will most probably running out of ressources. With each crime and every kindness we birth our future. |

Thanks for the answer !! All my 4 cores are running nearly 100% as it is right now. Is there anything i might have done wrong !? |

Nope, everything is like it is to be expected. With each crime and every kindness we birth our future. |

ok. Thanks for the answer. Must upgrade the CPU then. I have another card that i want to add !! |

It seems like every time I do an update my total work done gets LOWER despite having 4 laptops running. My average work done gets lower and lower and I do not understand why that is. HELP !!! The laptops are running from a Pentium to an i7. |

It seems like every time I do an update my total work done gets LOWER despite having 4 laptops running. My average work done gets lower and lower and I do not understand why that is. HELP !!! The laptops are running from a Pentium to an i7. None of those systems are big performers, however for starters I would de-select "Use Intel GPU" in your Seti settings as their performance isn't that great, and using them really, really slows down your CPU crunching. Once all of the those Intel GPU WUs have cleared, your CPU crunching performance should improve significantly. Edit- In Computing preferences, make sure "Suspend when computer is in use" is not selected and that "Use at most x % of the CPUs " and "Use at most x % of CPU time" are set to 100%. Unless you're trying to play a game, or running some other intensive programme on the Laptop, Seti is very good at not impacting on other programmes (particularly for CPU crunching). Being Laptops, it's worth checking to see that the power settings are set to "Maximum performance when on AC power", otherwise the CPU clock speed can be significantly reduced. Also make sure the laptops are on solid surfaces with nothing blocking the air from being drawn in the bottom & expelled out the rear or/and side(s). Grant Darwin NT |

Laptops are not ideal for crunching because their cooling is compromised. When I was using one a few years back I had to sit it on a pair of large fans to prevent it shutting down every few hours, then every few weeks very carefully removing all the dust that stuck to every cooling surface inside the beast (I got good at stripping it down and putting it back together without loosing any of the tiny screws and clips that held it together). These days aggressive use of things like Tthrottle may help in controlling the temperature, but they won't stop the problems with dust.

I looked at Jaye's computers and she has one with a (7488703) GT 750 that might benefit from a couple of changes. I would add this to the mb*sog.txt file in the Program Data directory (hidden so have to change to show hidden in Windows Explorer). -sbs 192 -spike_fft_thresh 2048 -tune 1 64 1 4 This may or maynot speed up your gpu processing. You have to re-read the config files, pause/restart the gpu or restart seti to get this read. ------------------------ If you want to continue gpu-based crunching on the other 3 intel boxes I propose the following change to the INTEL Intel(R) HD Graphics 4000 one (6762302 ). In the mb*sog.txt file. -spike_fft_thresh 2048 -tune 1 64 1 4 You have to re-read the config files, pause/restart the gpu or restart seti to get this read. Since the last two intel boxes don't mention any kind of video, if they are crunching on the gpu and you want to continue gpu crunching on the 6762302 box then we need to look around for the "doesn't use gpu" command and where to put it. Otherwise, as previously recommended, turn off the Intel gpu option. ------------------------------------------------------------------- Apparently your AuthenticAMD AMD Turion(tm) 64 X2 doesn't include an integrated GPU so if you look in your device manager and find out what the graphics card brand/model# is we MIGHT be able to offer some advice on getting that gpu to crunch better.
