Hi. I have an old PC, that I use only to work in Enigma,SETI@HOME and others but I want to do an upgrade in that PC, i'm think to put a video card with CUDA, but my mother board, just have PCI and AGP slots. = ( anyone know one video card with CUDA that use AGP or PCI ??? Thanks a lot. |

Hi. AGP isn't as far I've read capable of crunching, people in number crunching have asked that before, PCI can, but is slow, You might try in this thread here and look for the GT210 or the GT430, I'd get the card that has the most cuda cores of course and that has a fan on It. You might also look for a 9800GT, sure It's old, but It should be in PCI and this link here mentions which gpu has how many cuda cores, oh and ignore the buy It now link, there may be a very good reason, like no PCI cards in stock, just incompatible PCI-E cards, look to ebay for pci cards, use the last link as a guide as to what You want to get.

I got myself a Zotac PCI GT430 a couple of days ago: ZOTAC GeForce GT 430 or there is the PCI GT520, but that has half the stream processors: ZOTAC GeForce GT 520 These are both fanless designs, so you'll probably want to rig up a fan on a bracket pointing at the GPU slot. Claggy |

The highest rated AGP card that you can get is an ATI HD3850. I do not know if they are still available but i have two AGP HD4650 (320 stream proc`s) from ebay. and there was at one time some AGP HD 4670 around, same 320 SP`s but higher clocks. From my experience you will not be able to crunch SETI on the ATI AGP cards, Go for the nvidia cards. Unless things have changed recently and i did not notice it, The CPU`s on AGP boards do not have the needed SSE2 or SSE3 instruction sets needed to run the ATI open CL GPU seti applications. It is a show stopper :¬( |

Youre right this machine has SSE3 capable CPU and an AGP slot too. I thought about putting something OpenCL capable in it but kind of forgot about it(and rumors are ATI apps dont work well with AGP cards. Some kind of driver problem). |

my understanding of how GPU crunching works, is that there is a lot of traffic going both ways, and AGP does not run fast enough of the GPU to memory to support GPU crunching. |

Chris is correct, and the most powerful AGP GPU is the ATI HD3850. If this is updated with the ATI 11.3 driver with APP and AGP kit, then the ATI friendly projects can be crunched (Milkway, Collatz, DNETC, Moo! Wrapper, etc). If the PCI (not express) expansions slots are then filled with a couple of GeForce GT430s then CUDA projects (like SETI and Einstein, etc) can be crunched as well (in parallel). I do on a dual P3 with only PCI (not express), but run a pair of GeForce 9,500GTs successfully. I have yet to try this on SETI, but this is not possible ATM as I think the 450W PSU is defunct. It's good to be back amongst friends and colleagues |

The ATI HD3850 can run the AP hybrid application, but it does use mostly CPU. So if buying a new card a PCI NVIDIA solution would be a better bet. The highest rated AGP card that you can get is an ATI HD3850. What mutant MB do you have that is S775 & AGP? That must be almost as rare at the S478 & PCIe boards. Apparently the P4 530 has SSE3 did come in a S478 package. I have been trying to source one for my older system to see if I could give the OpenCL app a whirl on my HD3850. Ideally I would want to find a SL8JZ, SL79L, or SL7E4. SETI@home classic workunits: 93,865 CPU time: 863,447 hours Join the [url=http://tinyurl.com/8y46zvu]BP6/VP6 User Group[ |

OpenCL requirements for ATI's are HD4*** and higher, HD3850 won't do. http://developer.amd.com/sdks/AMDAPPSDK/pages/DriverCompatibility.aspx Claggy |

The AGP 4670 cards are still to be had on ebay uk http://www.ebay.co.uk/sch/i.html?_from=R40&_trksid=p5197.m570.l1313&_nkw=agp+4670&_sacat=58058 And some AGP 4650 are also there. |

I know that the CPU part is wrong, as i have a core 2 duo on a board with AGP. What motherboard are you using, Can you post the make, model, and part number this is an oddity i would like to know more about. To the point of possibly buying one if i can find one. Or some other core 2 ish + AGP board. Be it AMD or Intel. |

I search some video cards. but many is PCI-E but i found this, can work??? Thanks a lot to all the people that tri to help me. [url] http://produto.mercadolivre.com.br/MLB-201866533-placa-de-video-zotac-geforce-512mb-64-bit-ddr2-_JM[/url] |

I search some video cards. No good, if you look at the picture, you'll see it a Geforce 6200 (Geforce 8*** and later required for Cuda support) Claggy |

a core 2 duo on a board with AGP. The ASROCK 775i65G (don't ever use the ...GV 'board as it won't run Conroe) is a gem. There are probably others. The 775i65G runs quad-core CPU's too. I have one fitted with a Q6600. It requires CL2 memory which will enable 1066mhz:- the board automatically overclocks the RAM so it takes about 10 seconds longer during POST. The difference between 0 and 1 is greater than the difference between 1 and 1,000,000 |

I would just bite the bullet and upgrade the whole motherboard. You don't need to make it into some I7 supercruncher. Just a modern PCI-E board, some sort of CPU (pentium dual or Athlon X2, a stick of RAM and mid range graphics card. The existing PSU should run a mid-range card OK. The high end ones need the 600+watt power supplies. Now you have a useful cruncher and a good backup PC that you can play modern games over your LAN etc Just seems to make more sense than throwing $$ at an old machine, that's still going to be a dog. Spend slightly more and you have a reasonably current machine. Of course eventually you end up with something like my G/Fs machine. It's had so many upgrades over the years that the keyboard is the only original part :-) Ian |
