I imagine there's a celeron or p4 maybe even a amd k7 with multi highend graphic cards, giving it a big rac. Is there? Maybe there someday be a usb graphic card on an atom.

Well at work, the workstation at my desk is a P4 530 (LGA775, 3.0ghz, HT, 1MB L2, 800MHz FSB) that -could- have a CUDA card installed. right now it just has has a Silicon Image card that has about 15 components on it and a single DVI on the back. I think it works with the Intel 915 onboard graphics and provides a DVI link for it. I'm not going to spend money and put my own hardware in that equipment though.

The oldest machine I have that will support a CUDA card is a Celeron 2.6ghz (socket 775).

There are not many pre socket 775 boards that have PCIe slots.

But if I was to spring for a 200 series NVidia card, I wouldn't be putting it in the old Celeron.

I have a Northwood P4 3GHz + 8600GT Cuda card that had an RAC of 1260 and climbing before the current round of server problems began. It's currently running 912.

Before I upgraded it to Cuda it ran an RAC of around 600.

Has anyone tried a pci card? 8400gs or 9400gt? Available at new egg, could you run multipules of these?

I have a 2.6c here with an 8600GT in it, but I need a new power supply cos this one died :(

I am running 3 8400GS cards right now, on a Win 7 box, and just got a 260 as well, so am running 4 cards in it.

But..

Having some probs getting them to work with CUDA, been trying to run out my cache so I can try installing all the optimized apps and clients on here, to see what it really can do. There is another thread recently about vid card speeds and processing power, but to let you know, when I start BOINC, it sees all 4 cards, and here is the speed specs it lists (not very encouraging on the PCI front, the 8400GS is the fastest current PCI card I could find, though I didn't know about the 9400gt card as being PCI. Checked at Newegg, only brand 9400 that isn't PCI-E looks to be Sparkle, and they have pretty unfavorable reviews on that card. Too bad EVGA doesn't make one):

4/4/2009 11:46:02 PM CUDA devices: GeForce GTX 260 (driver version 18171, CUDA version 1.3, 896MB, est. 89GFLOPS), GeForce 8400 GS (driver version 18171, CUDA version 1.1, 512MB, est. 4GFLOPS), GeForce 8400 GS (driver version 18171, CUDA version 1.1, 512MB, est. 4GFLOPS), GeF

It cuts off the last card, must be a char limit per line, but as you can see, 4 gflops for a 8400, and 89 for a 260. I paid I think around $50 each for the 8400's, and a little under $200 for my 260 at Micro Center with a rebate. I also got a 250 to see what that will do on my new I7 I am building. Hope this helps, as I'm trying it, and will post the info on a new thread when I get it running, but I have to say from what I have seen so far, without actually running it but seeing the estimated speed in BOINC, I can't think it would really be worth it to load up a box with them, even if you have spare PCI slots. Save the money, and put together a low end new system with 1-2 PCI-E slots and a 250-260, and you'll be way ahead in terms of raw crunching power, I would assume. Just my 2 cents.

I was thinking of pci cards for older machines without pcie
maybe something running 333mz I gave away a bunch of slow machines, which were still good for e-mail and modest surfing ,was just wondering if those old machines could have crunched with multi pci cards.

gpu crunching needs a cuda card and they are pcie cards not pci cards. There are no pci cuda cards I know of all cuda cards are pcie cards.

They'll work, and aren't terribly expensive, as long as you go into it not expecting miracles (but if you are running 333 mhz machines, I don't think you would be...) Probably would exceed your CPU performace, I'd think.

my 8400gs (500mhz core clock) runs about 2.5 hours per wu. its pci-e. so that'ld be a best case scenario. altho with the speed of that card i dont imagine a pci bus hurting it too much.

theres a socket 478 board out there with pcie. so you can drop a big card on a small box. and some socket 754 (1st run athlon 64's). personally i cant see putting money into doing it tho. since you can get a quad core cpu, board, and ram for less than a decent crunching gpu.

im kinda curious to see how the ion boards do(atom with a 9400m)

A GTS250 card should have the same speed as my 9800GTX+ - about 3,700 cobblestones/day. I'd call that a pretty decent crunching card.

My local (UK) supplier charges 125 GBP for a GTS250 - well under $200. Where can you get a decent quad, MB and RAM for less than that? The same supplier is charging 249 GBP for a Q6600 bundle (pre-assembled with warranty - probably costs more than the individual components, but not double).

One of my Linux boxes (4082448) is a 754 board. I have a 6600GT in it right now, but that was an upgrade to the onboard video when I got an 8800GT for my main cruncher (2889590). I could drop a 9800GT or something similar into that box, but it is Linux, and I don't know how well the Linux port of CUDA is working at the moment..if at all. Not only that, but things are fine the way they are, presently, so it's best to just leave everything alone.

Well, Crunch3r's Linux CUDA build works fine. There's the CUDA slowdown for VLARs, but I think that is the same as for Windows.

One curiosity is whether the CUDA VLAR slowdown is affected by how much free GPU RAM your video card has...


Then again, if all is working fine for the moment, why change unless you want to experiment or "have a play"?

Happy crunchin',

it was a slight exageration. but for pure cpu horsepower try these:

how about a quad opteron for $200 ( 137 gbp)

http://sfbay.craigslist.org/pen/sys/1102626617.html less than 30 min from work. dual core opteron full system for $115.

gotta love retired corp gear. it aint pretty, its loud, but it'll crunch.

of course theres an 8800gt on ebay for 30 bux. hmmmmmmmm.
