Are there any PCI or AGP Cuda cards?

When I do searches all I can find are PCI-E cards for Cuda. Are there any choices for my old P4 2.8 machine? Official Abuser of Boinc Buttons... And no good credit hound! |

You could check this out - and I think there was an older thread about PCI card availability in Australia, too... -Dave |

How good did you look? ;-) Found a couple of PCI ones: http://www.sparkle.com.tw/product_detail.asp?id=82&sub_id=220 (scroll down), there's an 8400 (4x), 9400 (4x) and 9500 (2x). Found some on EVGA's site as well. 9 series (scroll down) 8 series (first one). |

I cheated on that though. ;-) Used Alternate (a Dutch online PC shop) to check what graphics card manufacturers they had and then went and looked on their sites. Checked some others as well and now know I never return to the Zotac and Club3D sites, because of their really annoying Flash use. |

Not to forget.. For max. CUDA performance you need a PCIe 1.0 x16 or PCIe 2.0 x8 slot on mobo for every GPU. Someone made a test here.. if you have a GPU at PCIe 1.0 x8 (PCIe 2.0 x4) it start to lose performance. AFAIK.. something around 5 % or something. IIRC if you go more down with the slot it's more and more lost.. not proportional.. the reduction increase disproportionately.. So you can calculate/guess down to a PCI slot. ;-) |

Are there any choices for my old P4 2.8 machine? Ya, I am using a JATON GeForce 9500 GT 1GB 128-bit DDR2 in my old Sempron rig (2261623). Got it from Newegg It was a semi cost effective way of upgrading the crunching of an older system that was limited to PCI only. The CUDA on my Sempron is 'supposed' to be doing two SETI to one Collatz. However, all by itself, my Collatz RAC is usually near 3k... BTW, if you don't already know, there are a few scheduling issues associated with having a fast(er) GPU and an average speed CPU... ;) |

There's a BFG 8400 GS 512MB as well. |

my opinion is if you fill a older motherboard that has say 5 pci slots and put 5 9500gt pci cards in it you have a six core machine the 9500gt's are almost as fast as a core 2 when it comes to seti multibeam so the gain in rac would be pretty good .. a few thousand maybe however on newegg they go for about $75 75 x5 ~~~ 375 for 375 you could get a motherboard a q8400 a 9600gso for the same price and this new system will out preform the old one by a LARGE margin |
