I have a gtx 260-216 vidieo card now running cuda great. I'm running an intel I7 with 12gb ram and I have an asus p6T mother board with 2 open pcie slots I have 2 9500gt's laying here and want to use them to crunch also. I install one the other day ..windows reconized both cards gpuz sees both cards I only have one display boinc does not see the other card. Do I need to do anything to my app info file to get it to see both cards, maybe cc_config ?
can't figure it out. Here is a copy of my app info file and my cc_config.

Thanks

Try the cc_config.xml:

<cc_config>
  <options>
      <use_all_gpus>1</use_all_gpus>
  </options>
</cc_config>

[edit] "use_all_gpus" is a flag - "0" = No, "1" = Yes. [/edit]

use_all_gpus should be set to one to turn it on, not to your number of gpus.

How do I configure my client using the cc_config.xml file?

Ok changed it to 1 restarted no good only one working the gtx 260

I think it has to do with the different generation of your video cards. If you ran the 2 9500Gt's , they would work. Or if you had 2 GTX 260's.

Here's my experience.
I ran 2 x 9800GT's. No problems. I added a 9800GX2 to the mix and still no problems. They all use the G92 core, though the 9800GX2 has 128SP vs the 112 on the 9800GT, the core is the same.

I added a GTX 260 to the above rig and windows/BOINC, everything recognized all the cards 9800GT x2, 9800GX2, GTX260, but BOINC would only work on the GTX 260, leaving all the other cards idle. When I removed the GTX 260 and rebooted, the other cards started crunching again.

that might be the problem then thanks Duner

@ ganja

Which PCIe version and electric connection the three slots on the mobo have?

PCIe 1.0/2.0 ? _x4, _x8, _x16 (electric!) ?

I couldn't imagine that this is the prob, but who know it? ;-)


@ Duner

You used/made this hint with cc_config.xml and use_all_gpus entry?
BOINC should use then all (also different) GPUs.

Which BOINC Version you use?

---

Also..

It depend which Windows OS.

I use WinXP and all GPUs running very well without to extend the Windows Desktop to all GPUs or insert dummy plugs in all GPUs.

After reading this forum, I guess you need to do this only with WinVista.


[ EDIT: Maybe with Win7 also? ]

---

On my experience with my i7, MSI Platinum board, i was able to run 2x 9600GT, or a GTS250+9600GT or 2x GTS250, but when i add a GTX 295 to the system, i wasn´t able to boot the system with any other card on the second slot.It was not power related, I think. Win XP didnt boot to the end.

---

If it helps at all, I'm running XP 64bit with a GTS 250 and a 9500GT and both are working fine for CUDA. Also, I'm using the GTS 250 as my monitor card.

---

The GTS 250 is a re-badged 9800GTX, so I would expect it to work with other 9x00 series cards.

I'm getting a 8800GT card soon and I don't expect and issues running beside my 9800GT's and 9800GX2 b/c they are all the G92 core.

---

Running 260+9800GTX+ on xp32 here:
host 5007936
This is the first i've heard of this..Have run an 8400GS+260 setup as well. Normally, if windows knows where the drivers are and boinc has the <use_all_gpus> flag set; I've only had to shutdown, swap whatever card, restart (maybe twice) and all is well.
Good luck, Keep crunching !

I'm beginning to think the problem might be vista64 or Win7 64 and by the way what is a dummy plug everyone is talking about? and where do I get one to see if that works.

Just google for "dummy plug". Lots of info.

it was the dummy plug guys ....built one in about 30 secs.

thanks for all your help.

Ganja

I use winxp 32, no dummy plugs needed.

The cc_config.xml worked for me though. I've got 2 9800GT's, 9800GX2, GTX 260 all crunching at the same time now. I'm going to be building a new rig and moving the GTX 260 to it though so it won't make a huge difference, but at least I know it works now. Thanks for the help.

mind you in boinc is the main issue for more then 1 card works some times
