So I recently assembled a new/old late 90's retro PC to compliment the rest of my fleet. Specs are AMD K6-2+ 550mhz, 768mb ram, 3Dfx Voodoo3. I built it primarily for DOS/98SE 3Dfx gaming, but I also have it dual booting Windows 7 and thought I would let it run a work unit or two just for fun. So far, it has failed on 3 of 3 work units with the stock s@h x86 app. http://setiathome.berkeley.edu/results.php?hostid=7830684 Does anyone know if the s@h app simply requires an instruction set not present in the K6-2+? Or is there some other setting I can try to get it to work? Before failing, the BOINC estimated time to completion was approximately 40 hours :). |

The CPU needs at least SSE to work. The K6 2 doesn`t support it. With each crime and every kindness we birth our future. |

See inside the WUs logfile: Unhandled Exception Detected... So yes, your CPU lacks needed instructions, obviously the SSE instructions. Aloha, Uli |

Understood, thanks! |

The CPU needs at least SSE to work. Not really I used (and may again use) K6-2+ on Windows 98 / Windows 2000 http://setiathome.berkeley.edu/show_host_detail.php?hostid=3412467 http://setiathome.berkeley.edu/host_app_versions.php?hostid=3412467 "Number of tasks completed 57" It have "Consecutive valid tasks 0" just because the last task was "Time out" Using: app_info.xml stock setiathome_7.00_windows_intelx86.exe (MD5: 61ed886de72526d5c9adda9fc120df0f) PSAPI.DLL (MD5: 7f7005d2f1d9c579179807818c3ac4c7) from Windows 2000 (needed when I run on Windows 98) put next to setiathome_7.00_windows_intelx86.exe Old libfftw3f-3-1-1a_upx.dll renamed to libfftw3f-3-3_upx.dll (MD5: faef6807b4fe889a33647a661c52d99e) (The problem with the new "real" libfftw3f-3-3 is that it needs CMOV instruction) - Not SSE app_info.xml <app_info> <app> <name>setiathome_v7</name> </app> <file_info> <name>setiathome_7.00_windows_intelx86.exe</name> <executable/> </file_info> <file_info> <name>setigraphics_7.00_windows_intelx86.exe</name> <executable/> </file_info> <file_info> <name>libfftw3f-3-3_upx.dll</name> <executable/> </file_info> <file_info> <name>Psapi.dll</name> <executable/> </file_info> <file_info> <name>wisdom.sah</name> </file_info> <app_version> <app_name>setiathome_v7</app_name> <version_num>700</version_num> <file_ref> <file_name>setiathome_7.00_windows_intelx86.exe</file_name> <main_program/> </file_ref> <file_ref> <file_name>setigraphics_7.00_windows_intelx86.exe</file_name> </file_ref> <file_ref> <file_name>libfftw3f-3-3_upx.dll</file_name> </file_ref> <file_ref> <file_name>Psapi.dll</file_name> <copy_file/> </file_ref> <file_ref> <file_name>wisdom.sah</file_name> <copy_file/> </file_ref> </app_version> </app_info> Â - ALF - "Find out what you don't do well ..... then don't do it!" :) Â |

Thank, BilBg. I honestly wasn't sure if SSE was a requirement or not. I'll sit down with it this evening and see if I can get it working! |

Wow, great analysis - one never stops learning something new! *twothumbsup* :) Aloha, Uli |

Same here , Decided to build a vintage PC some weeks ago (Pentium I @ 100mhz ,32Mb RAM , Win98 SE) , My idea was using it to play 16bits games and old software , But I thought .. "Imagine this piece of museum searrching for extraterrestrial life" , However , It went unsucessful and doesn't get any tasks . http://setiathome.berkeley.edu/show_host_detail.php?hostid=7820731 Maybe the client is too old or RAM it is not enough. I saw a lot of comments about the K6-2 , That was my office computer only 2 years ago (not kidding) , Runtimes were 96hours long . Seems like the app is now updated and needs the SSE instruction set. |

With only 32mb ram, BOINC would not download seti tasks. I tried it on one of my 486's a while back. It gave some message about insufficient memory. Does anyone know where I might find a copy of libfftw3f-3-1-1a_upx.dll? I've been searching with no luck for a few hours now. |
