I have an 8 Cpu "Cascades" Compaq Server with 8 x 2Mb Cache 700Mhz CPU's, 3.5Gb RAM and 4 x SCSI 10K 140Gb drives running Suse Enterprise Server http://setiathome.berkeley.edu/show_host_detail.php?hostid=2545894 Still dead slow of course... |

I usually run 3 Dual P3's (one Slot1 and 2 socket370). I just temporally retired one of them (a classic Abit VP6 board) - due to the "Bad Capasitor" syndrom (descriped at www.badcaps.net). It has beeen running SETI (and as fileserver) very stable for more than 5 yrs on Win2K - only booted when needed for updates and cleaning of fans). I'm awaiting some "1500uF 6,5v caps" to arrived in mailbox soon - and I'll give the board another try. I't really deserves it ;) Kiva Greetings from Norway Crunch3er & AK-V8 Inside |

The soldering is a pain! I ha problems to unsolder the caps as the use some kind of heatsink on the board (The board itself) use a bigger soldering iron, so you can heat both wires of the caps at a time |

Like everyone else that has posted, I also had (have) a fondness for the dual-P3's because of the reliability. They were (are) just simply stable workhorses. I built mine back then around a Supermicro P6DBU. Initially, I built it for video editing and creation, along with Photoshop work. Even put the Adaptec RAIDport card in and "R"AID 0'd a couple SCSI HDD's. Worked very well. (Don't bother looking for the ARO cards today as WinNT was the only OS that drivers were ever developed for them. Even the open source communities, unfortunetly, were never ever to develop drivers as Adaptec refused to give the intimate specs.) It served very well for video and photo work before "retiring" into a game rig. From game rig, it "retired" into a general purpose machine. From there, it eventually "retired" into doing home LAN server stuff under FreeBSD. Under all roles, it has run very faithfully for six years straight. Every six months I do housekeeping (cleaning, checking the caps, etc) on it, and expect it to continue for still many more years. Going dual and SCSI back then definetly gave it more longetivity... Likewise with others, I'd also have no problem (today) putting together a dual P3 for someone that just needs something for general purpose but on the cheap. In fact, a have another box built around a Supermicro 370DL3 doing just that. Sure, spec-wise, it is old on paper -- but real world use, when I click on Firefox it comes up almost instantly. Same with email, word processing, even streaming video. What more does it really need? |

I agree the dual P3's are the stable workhorses, that in many cases are still plodding on. I've retired mine from BOINC but it is still in use as an electronics measurement device, multimeter, scope, spectrum analyser and audio signal frequency signal source. Coppermine 933MHz, Gigabyte mobo, 512 KByte ram @133MHz. The original WD 10 GByte HDD is still operational but now runs with a 40. Andy |

That would be a nice addition to my museum... unfortunately, my cash is running low, and all my money is being saved up for an upgrade for my main system. I'm itching hard for a Core 2 Duo for me and an Athlon 64 X2 for my girlfriend (there's a slight possibility I might try to go for some dual Xeon 5130s for myself!). But I'd definitely like to get the VIA CPUs added to my collection of x86 compatible chips just so I can say I own one. 8-) |

I gave $103 each for Asus Terminator I C3's -- Case, Power Supply, Motherboard, Processor, Floppy and CD-ROM. Just added memory and a HD. |

It'll be done with it in 4 1/2 days. LOL That's about as fast as my AMD K6-2 500MHz CPU! And I think the K6-2 500 had a total power consumption of about 29 watts. Are you sure that's a good deal? ;-) |

This app. doesn't need a lot of computer, and it's way down from the Dual-PPro. |

Depends a lot on what's in the box, although the K6-2/500 should be a little higher. Well, that's true, and to be honest I didn't use any wattage meter or anything of the sort. I simply used AMD's own whitepaper about it's total draw for CPU alone. Though, if you're running a relatively old AGP card, no sound, CD drive (only uses power when in use) and HDD, it should be pretty close to the VIA C3, I'd presume. This app. doesn't need a lot of computer, and it's way down from the Dual-PPro. Very true, though unfortunately, I have to keep running systems down to a minimum to keep electricity costs down as much as possible, and since I already have a dual P3 file and print server running, replacing the Dual PPro with a VIA C3 is still going to be extra wattage over not running it (and taking down the dual P3 isn't going to be an option - it's the only way I could convince the girlfriend to let me have a dualie, even though file servers don't need dual, but that's beside my best intent of having a dualie). But I'm still interested in the unit, as I still plan to finish off my museum one of these days, and I want every generation of CPU from every manufacturer to be in it (including some slightly-modified CPUs of the same generation), so thanks for pointing me out to that good deal. |

Very true, though unfortunately, I have to keep running systems down to a minimum to keep electricity costs down as much as possible.... I know exactly what you're talking about here. Rates from Southern California Edison have gone basically nuts, especially if you get 200% over baseline. ... so, as a result, through various and sundry changes (including decommissioning the Dual-PPro) I've managed to get daily power consumption from 36kwh/day to 26kwh/day over the past 60 days or so. I'm hoping to get down another 3 or 4. An 800 MHz C3 is somewhere under 10w (I want to say 7w, but I'm going by memory) and the 43w came from an actual measurement. |

There is some really cool dual-P3 rackmount stuff going around really cheap these days too. I know I've been tempted, but I'm trying to hold restraint as I want to build something around quad-core and DirectX10 when the time comes... |
