Decided to give it a go just to see if it could do a unit in time and not only did it but actually has it pending...Check out this wooping time... 93,443.86 61.79 pending Official Abuser of Boinc Buttons... And no good credit hound! |

And a Celeron 400 comes somewhere in the middle, also with Simon's MMX v2.2 app. |

I got a P2-450 back up and running a couple of weeks ago. |

Yep, formerly known as the IDT WinChip and Cyrix processors when VIA first bought the line. In any event, the addition of the L2 cache in the cartridge on the Slot 1 PII's and the onboard cache (albeit small by today's standards) for Skt 370 makes all the difference in the world compared to the best you can get from Skt 3, 5, or 7. ;-) In fact those old PII's and early Slot 1 PIII's make a pretty good showing for themselves considering their age, and late model Skt 370 PIII's and Celery's have nothing to be ashamed of. :-) Alinator |

Ha, I used to have a cyrix...seems it was a 170 or 150 some oddball number...I was so exited when I was finally able to upgrade to a Pentium 233 MMX WOW that was the chip...LOL Official Abuser of Boinc Buttons...

Yep, formerly known as the IDT WinChip and Cyrix processors when VIA first bought the line. I did forget to mention that K6-III's and K6-2+'s can probably compete fairly well with late model PII's as well as early PIII's and Celery's, even though they are still Super 7 chips. Only problem is they are kind of scarce and pricey when you find them. I have a K6-III/450, but I'm still looking for a Asus P5a or Gigabyte (don't have the model # handy) MB to run it on so as to complete my collection of vintage K-6 units. ;-) Alinator |

Yeah, I have an old PII 300 MHz home server that crunches SETI with its few spare cycles ;) Its actually running an older version of the opti'd app, I wonder how much improvement it would get running the newest one. Host #2852429 |

Well lots of people say overclocking shortens a CPU's life well we will see. I overclocked the 400 MHZ to 448 MHZ, thats seems pretty decent for this old chip. I will let it run seti 24/7 untill it dies... Official Abuser of Boinc Buttons... And no good credit hound! |

God! this is like "old home week" for me....lol i still have: 1 486dx- 100 laptop 1 p1-100 laptop 1 cyrix i think its a 700mhz 1 k6-2 300 1 k6-2 333 1 k6-2+ 550 1 p2-400 1 p3-600 i'd run these but i haven't had to pay a heating bill this winter. i've actually had to cut the ac on. i do use the last three sporadically for dev projects. running a thin linux os to maximize the usefulness. |

I have a 400 MHz Pentium II running SuSE Linux 10.1. BOINC 5.8.11 gives it a 334 MIPS floating and 453 MIPS integer rating. I am running Einstein@home, SETI@home and QMC@home on it, meeting all deadlines. But I had to abandon BBC and climateprediction.net. Mission impossible!. Tullio |

I will let it run seti 24/7 untill it dies... It is still running strong and has an RAC of around 64. Suprised me I was figuring around 20.

Not too shabby for a dinosaur! :-) The superior FPU's and in cartridge L2, even at half speed, makes a tremendous difference compared to the contemporary Socket 7 designs from AMD up to the -2+'s and -III's at least. I've gotta get my hands on another Super 7 board to get my K6-III/450 running and see what it can do compared to my other K6 family boxes, and the Deschutes. Alinator |

I'd love to get my army of old systems online again - I just can't afford the electric bill (nor the AC [also electric] in the summer). And ComEd prices are expected to keep rising this summer, making it more difficult to afford. |

And ComEd prices are expected to keep rising this summer, making it more difficult to afford. I can relate, I have my extra machines in my office and justify them as heat and advertising.
